Library and Information Science Papers Discussed on Twitter: A new Network-based Approach for Measuring Public Attention

Publicado en línea: 03 Jul 2020
Páginas: 5 - 17

Resumen

AbstractPurpose

In recent years, one can witness a trend in research evaluation to measure the impact on society or attention to research by society (beyond science). We address the following question: can Twitter be meaningfully used for the mapping of public and scientific discourses?

Design/methodology/approach

Recently, Haunschild et al. (2019) introduced a new network-oriented approach for using Twitter data in research evaluation. Such a procedure can be used to measure the public discussion around a specific field or topic. In this study, we used all papers published in the Web of Science (WoS, Clarivate Analytics) subject category Information Science & Library Science to explore the publicly discussed topics from the area of library and information science (LIS) in comparison to the topics used by scholars in their publications in this area.

Findings

The results show that LIS papers are represented rather well on Twitter. Similar topics appear in the networks of author keywords of all LIS papers, not tweeted LIS papers, and tweeted LIS papers. The networks of the author keywords of all LIS papers and not tweeted LIS papers are most similar to each other.

Research limitations

Only papers published since 2011 with DOI were analyzed.

Practical implications

Although Twitter data do not seem to be useful for quantitative research evaluation, it seems that Twitter data can be used in a more qualitative way for mapping of public and scientific discourses.

Originality/value

This study explores a rather new methodology for comparing public and scientific discourses.

Historical Bibliometrics Using Google Scholar: The Case of Roman Law, 1727–2016

Publicado en línea: 03 Jul 2020
Páginas: 18 - 32

Resumen

AbstractPurpose

The purpose of this study is to investigate the historical and linguistic coverage of Google Scholar, using publications in the field of Roman law as an example.

Design/methodology/approach

To create a dataset of Roman law publications, we retrieved a total of 21,300 records of publications, published between years 1500 and 2016, with title including words denoting “Roman law” in English, French, German, Italian, and Spanish.

Findings

We were able to find publications dating back to 1727. The largest number of publications and authors date to the late 19th century, and this peak might be explained by the role of Roman law in French legal education at the time. Furthermore, we found exceptionally skewed concentration of publications to authors, as well as of citations to publications. We speculate that this could be explained by the long time-frame of the study, and the importance of classic works.

Research limitation

Major limitations, and potential future work, relate to data quality, and cleaning, disambiguation of publications and authors, as well as comparing coverage with other data sources.

Practical implications

We find Google Scholar to be a promising data source for historical bibliometrics. This approach may help bridge the gap between bibliometrics and the “digital humanities”.

Originality/value

Earlier studies have focused mainly on Google Scholar's coverage of publications and citations in general, or in specific fields. The historical coverage has, however, received less attention.

Evidence-based Nomenclature and Taxonomy of Research Impact Indicators

Publicado en línea: 03 Jul 2020
Páginas: 33 - 56

Resumen

AbstractPurpose

This study aims to classify research impact indicators based on their characteristics and scope. A concept of evidence-based nomenclature of research impact (RI) indicator has been introduced for generalization and transformation of scope.

Design/methodology/approch

Literature was collected related to the research impact assessment. It was categorized in conceptual and applied case studies. One hundred and nineteen indicators were selected to prepare classification and nomenclature. The nomenclature was developed based on the principle—“every indicator is a contextual-function to explain the impact”. Every indicator was disintegrated into three parts, i.e. Function, Domain, and Target Areas.

Findings

The main functions of research impact indicators express improvement (63%), recognition (23%), and creation/development (14%). The focus of research impact indicators in literature is more towards the academic domain (59%) whereas the environment/sustainability domain is least considered (4%). As a result, research impact related to the research aspects is felt the most (29%). Other target areas include system and services, methods and procedures, networking, planning, policy development, economic aspects and commercialisation, etc.

Research limitations

This research applied to 119 research impact indicators. However, the inclusion of additional indicators may change the result.

Practical implications

The plausible effect of nomenclature is a better organization of indicators with appropriate tags of functions, domains, and target areas. This approach also provides a framework of indicator generalization and transformation. Therefore, similar indicators can be applied in other fields and target areas with modifications.

Originality/value

The development of nomenclature for research impact indicators is a novel approach in scientometrics. It is developed on the same line as presented in other scientific disciplines, where fundamental objects need to classify on common standards such as biology and chemistry.

Classification of Paper Values Based on Citation Rank and PageRank

Publicado en línea: 28 Jul 2020
Páginas: 57 - 70

Resumen

AbstractPurpose

The number of citations has been widely used to measure the significance of a paper. However, there is a need in introducing another index to determine superiority or inferiority of papers with the same number of citations. We determine superiority or inferiority of papers by using the ranking based on the number of citations and PageRank.

Design/methodology/approach

We show the positive linear correlation between Citation Rank (the ranking of the number of citation) and PageRank. On this basis, we identify high-quality, prestige, emerging, and popular papers.

Findings

We found that the high-quality papers belong to the subjects of biochemistry and molecular biology, chemistry, and multidisciplinary sciences. The prestige papers correspond to the subjects of computer science, engineering, and information science. The emerging papers are related to biochemistry and molecular biology, as well as those published in the journal “Cell.” The popular papers belong to the subject of multidisciplinary sciences.

Research limitations

We analyze the Science Citation Index Expanded (SCIE) from 1981 to 2015 to calculate Citation Rank and PageRank within a citation network consisting of 34,666,719 papers and 591,321,826 citations.

Practical implications

Our method is applicable to forecast emerging fields of research subjects in science and helps policymakers to consider science policy.

Originality/value

We calculated PageRank for a giant citation network which is extremely larger than the citation networks investigated by previous researchers.

The Compound F2-index and the Compound H-index as Extension of the f2 and h-indexes from a Dynamic Perspective

Publicado en línea: 03 Jul 2020
Páginas: 71 - 83

Resumen

AbstractPurpose

Elaboration of an indicator to include the dynamic aspect of citations in bibliometric indexes.

Design/methodology/approach

A new bibliometric methodology—the f2-index—is applied at the career level and at the level of the recent 5 years to analyze the dynamic aspect of bibliometrics. The method is applied, as an illustration, to the field of corporate governance.

Findings

The compound F2-index as an extension of the f2-index recognizes past achievements but also values new research work with potential. The method is extended to the h-index and the h2-index. An activity index is defined as the ratio between the recent h’-index to the career h-index.

Research limitations

The compound F2 and H-indexes are PAC, probably approximately correct, and depend on the selection and database.

Practical implications

The F2- and H compound indexes allow identifying the rising stars of a field from a dynamic perspective. The activity ratio highlights the contribution of younger researchers.

Originality/value

The new methodology demonstrates the underestimated dynamic capacity of bibliometric research.

Co-author Weighting in Bibliometric Methodology and Subfields of a Scientific Discipline

Publicado en línea: 03 Jul 2020
Páginas: 84 - 96

Resumen

AbstractPurpose

To give a theoretical framework to measure the relative impact of bibliometric methodology on the subfields of a scientific discipline, and how that impact depends on the method of evaluation used to credit individual scientists with citations and publications. The authors include a study of the discipline of physics to illustrate the method. Indicators are introduced to measure the proportion of a credit space awarded to a subfield or a set of authors.

Design/methodology/approach

The theoretical methodology introduces the notion of credit spaces for a discipline. These quantify the total citation or publication credit accumulated by the scientists in the discipline. One can then examine how the credit is divided among the subfields. The design of the physics study uses the American Physical Society print journals to assign subdiscipline classifications to articles and gather citation, publication, and author information. Credit spaces for the collection of Physical Review Journal articles are computed as a proxy for physics.

Findings

There is a substantial difference in the value or impact of a specific subfield depending on the credit system employed to credit individual authors.

Research limitations

Subfield classification information is difficult to obtain. In the illustrative physics study, subfields are treated in groups designated by the Physical Review journals. While this collection of articles represents a broad part of the physics literature, it is not all the literature nor a random sample.

Practical implications

The method of crediting individual scientists has consequences beyond the individual and affects the perceived impact of whole subfields and institutions.

Originality/value

The article reveals the consequences of bibliometric methodology on subfields of a disciple by introducing a systematic theoretical framework for measuring the consequences.

A Novel Method for Resolving and Completing Authors’ Country Affiliation Data in Bibliographic Records

Publicado en línea: 09 Jul 2020
Páginas: 97 - 115

Resumen

AbstractPurpose

Our work seeks to overcome data quality issues related to incomplete author affiliation data in bibliographic records in order to support accurate and reliable measurement of international research collaboration (IRC).

Design/methodology/approch

We propose, implement, and evaluate a method that leverages the Web-based knowledge graph Wikidata to resolve publication affiliation data to particular countries. The method is tested with general and domain-specific data sets.

Findings

Our evaluation covers the magnitude of improvement, accuracy, and consistency. Results suggest the method is beneficial, reliable, and consistent, and thus a viable and improved approach to measuring IRC.

Research limitations

Though our evaluation suggests the method works with both general and domain-specific bibliographic data sets, it may perform differently with data sets not tested here. Further limitations stem from the use of the R programming language and R libraries for country identification as well as imbalanced data coverage and quality in Wikidata that may also change over time.

Practical implications

The new method helps to increase the accuracy in IRC studies and provides a basis for further development into a general tool that enriches bibliographic data using the Wikidata knowledge graph.

Originality

This is the first attempt to enrich bibliographic data using a peer-produced, Web-based knowledge graph like Wikidata.

The Gender Patenting Gap: A Study on the Iberoamerican Countries

Publicado en línea: 03 Jul 2020
Páginas: 116 - 128

Resumen

AbstractPurpose

This work presents a study on the female involvement in patent applications in all 23 Ibero-American countries that are WIPO members, in order to measure gender inequalities in institutional collaborations and technological fields, across time.

Design/methodology/approach

The data used in this paper come from EPO Worldwide Patent Statistical Database (PATSTAT). PATSTAT contains bibliographical data relating to more than 100 million patent documents from leading industrialized and developing countries, as well as legal event data from more than 40 patent authorities contained in the EPO worldwide legal event data (INPADOC). The extracted subset is composed of 150,863 patent applications with priority years between 2007 and 2016.

Findings

Our observations indicate that even in more dynamic economies such as Portugal and Spain, the participation of women per patent applications does not exceed 30%. Additionally, the distribution of female participation among institutional sectors and technological fields is consistent with previous studies in other regions and indicate a socio-cultural divide.

Research limitations

Unisex names were not considered and were counted as gender unknown, and patent applications for which no inventor information was available were discarded, but further effort of data analysis may provide more information about gender inequalities.

Practical implications

While patents are imperfect variables of inventive step and therefore should be considered as a variable proxy of innovation, our findings may help to guide the implementation of policies for balancing gender participation in innovative activities, as well as instigating research into the issues causing divisive participation along gender lines.

Originality/value

While there is a widespread effort into evaluating and improving the participation of groups recognized as minorities within state-of-the-art activities, research about women participation in the innovation sector is fragmented due to differing regional characteristics: industrial and academic segmentation, socio-economic disparities, and cultural factors. Thus, localized studies present an opportunity of filling the gaps of knowledge on societal participation in innovation activities.

A Tailor-made Data Quality Approach for Higher Educational Data

Publicado en línea: 09 Jul 2020
Páginas: 129 - 160

Resumen

AbstractPurpose

This paper relates the definition of data quality procedures for knowledge organizations such as Higher Education Institutions. The main purpose is to present the flexible approach developed for monitoring the data quality of the European Tertiary Education Register (ETER) database, illustrating its functioning and highlighting the main challenges that still have to be faced in this domain.

Design/methodology/approach

The proposed data quality methodology is based on two kinds of checks, one to assess the consistency of cross-sectional data and the other to evaluate the stability of multiannual data. This methodology has an operational and empirical orientation. This means that the proposed checks do not assume any theoretical distribution for the determination of the threshold parameters that identify potential outliers, inconsistencies, and errors in the data.

Findings

We show that the proposed cross-sectional checks and multiannual checks are helpful to identify outliers, extreme observations and to detect ontological inconsistencies not described in the available meta-data. For this reason, they may be a useful complement to integrate the processing of the available information.

Research limitations

The coverage of the study is limited to European Higher Education Institutions. The cross-sectional and multiannual checks are not yet completely integrated.

Practical implications

The consideration of the quality of the available data and information is important to enhance data quality-aware empirical investigations, highlighting problems, and areas where to invest for improving the coverage and interoperability of data in future data collection initiatives.

Originality/value

The data-driven quality checks proposed in this paper may be useful as a reference for building and monitoring the data quality of new databases or of existing databases available for other countries or systems characterized by high heterogeneity and complexity of the units of analysis without relying on pre-specified theoretical distributions.

Co-occurrence of Cell Lines, Basal Media and Supplementation in the Biomedical Research Literature

Publicado en línea: 03 Jul 2020
Páginas: 161 - 177

Resumen

AbstractPurpose

The use of in vitro cell culture and experimentation is a cornerstone of biomedical research, however, more attention has recently been given to the potential consequences of using such artificial basal medias and undefined supplements. As a first step towards better understanding and measuring the impact these systems have on experimental results, we use text mining to capture typical research practices and trends around cell culture.

Design/methodology/approach

To measure the scale of in vitro cell culture use, we have analyzed a corpus of 94,695 research articles that appear in biomedical research journals published in ScienceDirect from 2000–2018. Central to our investigation is the observation that studies using cell culture describe conditions using the typical sentence structure of cell line, basal media, and supplemented compounds. Here we tag our corpus with a curated list of basal medias and the Cellosaurus ontology using the Aho-Corasick algorithm. We also processed the corpus with Stanford CoreNLP to find nouns that follow the basal media, in an attempt to identify supplements used.

Findings

Interestingly, we find that researchers frequently use DMEM even if a cell line's vendor recommends less concentrated media. We see long-tailed distributions for the usage of media and cell lines, with DMEM and RPMI dominating the media, and HEK293, HEK293T, and HeLa dominating cell lines used.

Research limitations

Our analysis was restricted to documents in ScienceDirect, and our text mining method achieved high recall but low precision and mandated manual inspection of many tokens.

Practical implications

Our findings document current cell culture practices in the biomedical research community, which can be used as a resource for future experimental design.

Originality/value

No other work has taken a text mining approach to surveying cell culture practices in biomedical research.

Acknowledgment of Libraries in the Journal Literature: An Exploratory Study

Publicado en línea: 03 Jul 2020
Páginas: 178 - 186

Resumen

AbstractPurpose

This study examines acknowledgments to libraries in the journal literature, as well as the efficacy of using Web of Science (WoS) to locate general acknowledgment text.

Design/methodology/approach

This mixed-methods approach quantifies and characterizes acknowledgments to libraries in the journal literature. Using WoS's Funding Text field, the acknowledgments for six peer universities were identified and then characterized. The efficacy of using WoS to locate library acknowledgments was assessed by comparing the WoS Funding Text search results to the actual acknowledgment text found in the articles.

Findings

Acknowledgments to libraries were found in articles at all six peer universities, though the absolute and relative numbers were quite low (< 0.5%). Most of the library acknowledgments were for resources (collections, funding, etc.), and many were concentrated in natural history (e.g. zoology). Examination of Texas A&M University zoology articles found that 91.7% of the funding information came from “acknowledgments” and not specifically a funding acknowledgment section. The WoS Funding Text search found 56% of the library acknowledgments compared to a search of the actual acknowledgment text in the articles.

Research limitations

Limiting publications to journals, using a single truncated search term, and including only six research universities in the United States.

Practical implications

This study examined library acknowledgments, but the same approach could be applied to searches of other keywords, institutions/organizations, individuals, etc. While not specifically designed to search general acknowledgments, WoS's Funding Text field can be used as an exploratory tool to search acknowledgments beyond funding.

Originality/value

There are a few studies that have examined library acknowledgments in the scholarly literature, though to date none of those studies have examined the efficacy of using the WoS Funding Text field to locate those library acknowledgments within the journal literature.

Scientometric Implosion that Leads to Explosion: Case Study of Armenian Journals

Publicado en línea: 03 Jul 2020
Páginas: 187 - 196

Resumen

AbstractPurpose

The purpose of this study is to introduce a new concept and term into the scientometric discourse and research—scientometric implosion—and test the idea on the example of the Armenian journals. The article argues that the existence of a compressed scientific area in the country makes pressure on the journals and after some time this pressure makes one or several journals explode—break the limited national scientific area and move to the international arena. As soon as one of the local journals breaks through this compressed space and appears at an international level, further explosion happens, which makes the other journals follow the same path.

Design/methodology/approach

Our research is based on three international scientific databases—WoS, Scopus, and RISC CC, from where we have retrieved information about the Armenian journals indexed there and citations received by those journals and one national database—the Armenian Science Citation Index. Armenian Journal Impact Factor (ArmJIF) was calculated for the local Armenian journals based on the general impact factor formula. Journals were classified according to Glänzel and Schubert (2003).

Findings

Our results show that the science policy developed by the scientific authorities of Armenia and the introduction of ArmJIF have made the Armenian journals comply with international standards and resulted in some local journals to break the national scientific territory and be indexed in international scientific databases of RISC, Scopus, and WoS. Apart from complying with technical requirements, the journals start publishing articles also in foreign languages. Although nearly half of the local journals are in the fields of social sciences and humanities, only one journal from that field is indexed in international scientific databases.

Research limitation

One of the limitations of the study is that it was performed on the example of only one state and the second one is that more time passage is needed to firmly evaluate the results. However, the introduction of the concept can inspire other similar case study.

Practical implications

The new term and relevant model offered in the article can practically be used for the development of national journals.

Originality/value

The article proposes a new term and a concept in scientometrics.

Discipline Impact Factor: Some of Its History, Some of the Author's Experience of Its Application, the Continuing Reasons for Its Use and… Next Beyond

Publicado en línea: 03 Jul 2020
Páginas: 197 - 209

Resumen

AbstractPurpose

This work aims to consider the role and some of the 42-year history of the discipline impact factor (DIF) in evaluation of serial publications. Also, the original “symmetric” indicator called the “discipline susceptibility factor” is to be presented.

Design/methodology/approach

In accordance with the purpose of the work, the methods are analytical interpretation of the scientific literature related to this problem as well as speculative explanations. The information base of the research is bibliometric publications dealing with impact, impact factor, discipline impact factor, and discipline susceptibility factor.

Findings

Examples of the DIF application and modification of the indicator are given. It is shown why research and university libraries need to use the DIF to evaluate serials in conditions of scarce funding for subscription to serial publications, even if open access is available. The role of the DIF for evaluating journals by authors of scientific papers when choosing a good and right journal for submitting a paper is also briefly discussed. An original indicator “symmetrical” to the DIF (the “discipline susceptibility factor”) and its differences from the DIF in terms of content and purpose of evaluation are also briefly presented.

Research limitations

The selection of publications for the information base of the research did not include those in which the DIF was only mentioned, used partially or not for its original purpose. Restrictions on the length of the article to be submitted in this special issue of the JDIS also caused exclusion even a number of completely relevant publications. Consideration of the DIF is not placed in the context of describing other derivatives from the Garfield impact factor.

Practical implications

An underrated bibliometric indicator, viz. the discipline impact factor is being promoted for the practical application. An original indicator “symmetrical” to DIF has been proposed in order of searching serial publications representing the external research fields that might fit for potential applications of the results of scientific activities obtained within the framework of the specific research field represented by the cited specialized journals. Both can be useful in research and university libraries in their endeavors to improve scientific information services. Also, both can be used for evaluating journals by authors of scientific papers when choosing a journal to submit a paper.

Originality/value

The article substantiates the need to evaluate scientific serial publications in library activities—even in conditions of access to huge and convenient databases (subscription packages) and open access to a large number of serial publications. It gives a mini-survey of the history of one of the methods of such evaluation, and offers an original method for evaluating scientific serial publications.

Classification of Paper Values Based on Citation Rank and PageRank

Publicado en línea: 28 Jul 2020
Páginas: 57 - 70

Resumen

AbstractPurpose

The number of citations has been widely used to measure the significance of a paper. However, there is a need in introducing another index to determine superiority or inferiority of papers with the same number of citations. We determine superiority or inferiority of papers by using the ranking based on the number of citations and PageRank.

Design/methodology/approach

We show the positive linear correlation between Citation Rank (the ranking of the number of citation) and PageRank. On this basis, we identify high-quality, prestige, emerging, and popular papers.

Findings

We found that the high-quality papers belong to the subjects of biochemistry and molecular biology, chemistry, and multidisciplinary sciences. The prestige papers correspond to the subjects of computer science, engineering, and information science. The emerging papers are related to biochemistry and molecular biology, as well as those published in the journal “Cell.” The popular papers belong to the subject of multidisciplinary sciences.

Research limitations

We analyze the Science Citation Index Expanded (SCIE) from 1981 to 2015 to calculate Citation Rank and PageRank within a citation network consisting of 34,666,719 papers and 591,321,826 citations.

Practical implications

Our method is applicable to forecast emerging fields of research subjects in science and helps policymakers to consider science policy.

Originality/value

We calculated PageRank for a giant citation network which is extremely larger than the citation networks investigated by previous researchers.

The Compound F2-index and the Compound H-index as Extension of the f2 and h-indexes from a Dynamic Perspective

Publicado en línea: 03 Jul 2020
Páginas: 71 - 83

Resumen

AbstractPurpose

Elaboration of an indicator to include the dynamic aspect of citations in bibliometric indexes.

Design/methodology/approach

A new bibliometric methodology—the f2-index—is applied at the career level and at the level of the recent 5 years to analyze the dynamic aspect of bibliometrics. The method is applied, as an illustration, to the field of corporate governance.

Findings

The compound F2-index as an extension of the f2-index recognizes past achievements but also values new research work with potential. The method is extended to the h-index and the h2-index. An activity index is defined as the ratio between the recent h’-index to the career h-index.

Research limitations

The compound F2 and H-indexes are PAC, probably approximately correct, and depend on the selection and database.

Practical implications

The F2- and H compound indexes allow identifying the rising stars of a field from a dynamic perspective. The activity ratio highlights the contribution of younger researchers.

Originality/value

The new methodology demonstrates the underestimated dynamic capacity of bibliometric research.

Co-author Weighting in Bibliometric Methodology and Subfields of a Scientific Discipline

Publicado en línea: 03 Jul 2020
Páginas: 84 - 96

Resumen

AbstractPurpose

To give a theoretical framework to measure the relative impact of bibliometric methodology on the subfields of a scientific discipline, and how that impact depends on the method of evaluation used to credit individual scientists with citations and publications. The authors include a study of the discipline of physics to illustrate the method. Indicators are introduced to measure the proportion of a credit space awarded to a subfield or a set of authors.

Design/methodology/approach

The theoretical methodology introduces the notion of credit spaces for a discipline. These quantify the total citation or publication credit accumulated by the scientists in the discipline. One can then examine how the credit is divided among the subfields. The design of the physics study uses the American Physical Society print journals to assign subdiscipline classifications to articles and gather citation, publication, and author information. Credit spaces for the collection of Physical Review Journal articles are computed as a proxy for physics.

Findings

There is a substantial difference in the value or impact of a specific subfield depending on the credit system employed to credit individual authors.

Research limitations

Subfield classification information is difficult to obtain. In the illustrative physics study, subfields are treated in groups designated by the Physical Review journals. While this collection of articles represents a broad part of the physics literature, it is not all the literature nor a random sample.

Practical implications

The method of crediting individual scientists has consequences beyond the individual and affects the perceived impact of whole subfields and institutions.

Originality/value

The article reveals the consequences of bibliometric methodology on subfields of a disciple by introducing a systematic theoretical framework for measuring the consequences.

A Novel Method for Resolving and Completing Authors’ Country Affiliation Data in Bibliographic Records

Publicado en línea: 09 Jul 2020
Páginas: 97 - 115

Resumen

AbstractPurpose

Our work seeks to overcome data quality issues related to incomplete author affiliation data in bibliographic records in order to support accurate and reliable measurement of international research collaboration (IRC).

Design/methodology/approch

We propose, implement, and evaluate a method that leverages the Web-based knowledge graph Wikidata to resolve publication affiliation data to particular countries. The method is tested with general and domain-specific data sets.

Findings

Our evaluation covers the magnitude of improvement, accuracy, and consistency. Results suggest the method is beneficial, reliable, and consistent, and thus a viable and improved approach to measuring IRC.

Research limitations

Though our evaluation suggests the method works with both general and domain-specific bibliographic data sets, it may perform differently with data sets not tested here. Further limitations stem from the use of the R programming language and R libraries for country identification as well as imbalanced data coverage and quality in Wikidata that may also change over time.

Practical implications

The new method helps to increase the accuracy in IRC studies and provides a basis for further development into a general tool that enriches bibliographic data using the Wikidata knowledge graph.

Originality

This is the first attempt to enrich bibliographic data using a peer-produced, Web-based knowledge graph like Wikidata.

The Gender Patenting Gap: A Study on the Iberoamerican Countries

Publicado en línea: 03 Jul 2020
Páginas: 116 - 128

Resumen

AbstractPurpose

This work presents a study on the female involvement in patent applications in all 23 Ibero-American countries that are WIPO members, in order to measure gender inequalities in institutional collaborations and technological fields, across time.

Design/methodology/approach

The data used in this paper come from EPO Worldwide Patent Statistical Database (PATSTAT). PATSTAT contains bibliographical data relating to more than 100 million patent documents from leading industrialized and developing countries, as well as legal event data from more than 40 patent authorities contained in the EPO worldwide legal event data (INPADOC). The extracted subset is composed of 150,863 patent applications with priority years between 2007 and 2016.

Findings

Our observations indicate that even in more dynamic economies such as Portugal and Spain, the participation of women per patent applications does not exceed 30%. Additionally, the distribution of female participation among institutional sectors and technological fields is consistent with previous studies in other regions and indicate a socio-cultural divide.

Research limitations

Unisex names were not considered and were counted as gender unknown, and patent applications for which no inventor information was available were discarded, but further effort of data analysis may provide more information about gender inequalities.

Practical implications

While patents are imperfect variables of inventive step and therefore should be considered as a variable proxy of innovation, our findings may help to guide the implementation of policies for balancing gender participation in innovative activities, as well as instigating research into the issues causing divisive participation along gender lines.

Originality/value

While there is a widespread effort into evaluating and improving the participation of groups recognized as minorities within state-of-the-art activities, research about women participation in the innovation sector is fragmented due to differing regional characteristics: industrial and academic segmentation, socio-economic disparities, and cultural factors. Thus, localized studies present an opportunity of filling the gaps of knowledge on societal participation in innovation activities.

A Tailor-made Data Quality Approach for Higher Educational Data

Publicado en línea: 09 Jul 2020
Páginas: 129 - 160

Resumen

AbstractPurpose

This paper relates the definition of data quality procedures for knowledge organizations such as Higher Education Institutions. The main purpose is to present the flexible approach developed for monitoring the data quality of the European Tertiary Education Register (ETER) database, illustrating its functioning and highlighting the main challenges that still have to be faced in this domain.

Design/methodology/approach

The proposed data quality methodology is based on two kinds of checks, one to assess the consistency of cross-sectional data and the other to evaluate the stability of multiannual data. This methodology has an operational and empirical orientation. This means that the proposed checks do not assume any theoretical distribution for the determination of the threshold parameters that identify potential outliers, inconsistencies, and errors in the data.

Findings

We show that the proposed cross-sectional checks and multiannual checks are helpful to identify outliers, extreme observations and to detect ontological inconsistencies not described in the available meta-data. For this reason, they may be a useful complement to integrate the processing of the available information.

Research limitations

The coverage of the study is limited to European Higher Education Institutions. The cross-sectional and multiannual checks are not yet completely integrated.

Practical implications

The consideration of the quality of the available data and information is important to enhance data quality-aware empirical investigations, highlighting problems, and areas where to invest for improving the coverage and interoperability of data in future data collection initiatives.

Originality/value

The data-driven quality checks proposed in this paper may be useful as a reference for building and monitoring the data quality of new databases or of existing databases available for other countries or systems characterized by high heterogeneity and complexity of the units of analysis without relying on pre-specified theoretical distributions.

Co-occurrence of Cell Lines, Basal Media and Supplementation in the Biomedical Research Literature

Publicado en línea: 03 Jul 2020
Páginas: 161 - 177

Resumen

AbstractPurpose

The use of in vitro cell culture and experimentation is a cornerstone of biomedical research, however, more attention has recently been given to the potential consequences of using such artificial basal medias and undefined supplements. As a first step towards better understanding and measuring the impact these systems have on experimental results, we use text mining to capture typical research practices and trends around cell culture.

Design/methodology/approach

To measure the scale of in vitro cell culture use, we have analyzed a corpus of 94,695 research articles that appear in biomedical research journals published in ScienceDirect from 2000–2018. Central to our investigation is the observation that studies using cell culture describe conditions using the typical sentence structure of cell line, basal media, and supplemented compounds. Here we tag our corpus with a curated list of basal medias and the Cellosaurus ontology using the Aho-Corasick algorithm. We also processed the corpus with Stanford CoreNLP to find nouns that follow the basal media, in an attempt to identify supplements used.

Findings

Interestingly, we find that researchers frequently use DMEM even if a cell line's vendor recommends less concentrated media. We see long-tailed distributions for the usage of media and cell lines, with DMEM and RPMI dominating the media, and HEK293, HEK293T, and HeLa dominating cell lines used.

Research limitations

Our analysis was restricted to documents in ScienceDirect, and our text mining method achieved high recall but low precision and mandated manual inspection of many tokens.

Practical implications

Our findings document current cell culture practices in the biomedical research community, which can be used as a resource for future experimental design.

Originality/value

No other work has taken a text mining approach to surveying cell culture practices in biomedical research.

Acknowledgment of Libraries in the Journal Literature: An Exploratory Study

Publicado en línea: 03 Jul 2020
Páginas: 178 - 186

Resumen

AbstractPurpose

This study examines acknowledgments to libraries in the journal literature, as well as the efficacy of using Web of Science (WoS) to locate general acknowledgment text.

Design/methodology/approach

This mixed-methods approach quantifies and characterizes acknowledgments to libraries in the journal literature. Using WoS's Funding Text field, the acknowledgments for six peer universities were identified and then characterized. The efficacy of using WoS to locate library acknowledgments was assessed by comparing the WoS Funding Text search results to the actual acknowledgment text found in the articles.

Findings

Acknowledgments to libraries were found in articles at all six peer universities, though the absolute and relative numbers were quite low (< 0.5%). Most of the library acknowledgments were for resources (collections, funding, etc.), and many were concentrated in natural history (e.g. zoology). Examination of Texas A&M University zoology articles found that 91.7% of the funding information came from “acknowledgments” and not specifically a funding acknowledgment section. The WoS Funding Text search found 56% of the library acknowledgments compared to a search of the actual acknowledgment text in the articles.

Research limitations

Limiting publications to journals, using a single truncated search term, and including only six research universities in the United States.

Practical implications

This study examined library acknowledgments, but the same approach could be applied to searches of other keywords, institutions/organizations, individuals, etc. While not specifically designed to search general acknowledgments, WoS's Funding Text field can be used as an exploratory tool to search acknowledgments beyond funding.

Originality/value

There are a few studies that have examined library acknowledgments in the scholarly literature, though to date none of those studies have examined the efficacy of using the WoS Funding Text field to locate those library acknowledgments within the journal literature.

Scientometric Implosion that Leads to Explosion: Case Study of Armenian Journals

Publicado en línea: 03 Jul 2020
Páginas: 187 - 196

Resumen

AbstractPurpose

The purpose of this study is to introduce a new concept and term into the scientometric discourse and research—scientometric implosion—and test the idea on the example of the Armenian journals. The article argues that the existence of a compressed scientific area in the country makes pressure on the journals and after some time this pressure makes one or several journals explode—break the limited national scientific area and move to the international arena. As soon as one of the local journals breaks through this compressed space and appears at an international level, further explosion happens, which makes the other journals follow the same path.

Design/methodology/approach

Our research is based on three international scientific databases—WoS, Scopus, and RISC CC, from where we have retrieved information about the Armenian journals indexed there and citations received by those journals and one national database—the Armenian Science Citation Index. Armenian Journal Impact Factor (ArmJIF) was calculated for the local Armenian journals based on the general impact factor formula. Journals were classified according to Glänzel and Schubert (2003).

Findings

Our results show that the science policy developed by the scientific authorities of Armenia and the introduction of ArmJIF have made the Armenian journals comply with international standards and resulted in some local journals to break the national scientific territory and be indexed in international scientific databases of RISC, Scopus, and WoS. Apart from complying with technical requirements, the journals start publishing articles also in foreign languages. Although nearly half of the local journals are in the fields of social sciences and humanities, only one journal from that field is indexed in international scientific databases.

Research limitation

One of the limitations of the study is that it was performed on the example of only one state and the second one is that more time passage is needed to firmly evaluate the results. However, the introduction of the concept can inspire other similar case study.

Practical implications

The new term and relevant model offered in the article can practically be used for the development of national journals.

Originality/value

The article proposes a new term and a concept in scientometrics.

Discipline Impact Factor: Some of Its History, Some of the Author's Experience of Its Application, the Continuing Reasons for Its Use and… Next Beyond

Publicado en línea: 03 Jul 2020
Páginas: 197 - 209

Resumen

AbstractPurpose

This work aims to consider the role and some of the 42-year history of the discipline impact factor (DIF) in evaluation of serial publications. Also, the original “symmetric” indicator called the “discipline susceptibility factor” is to be presented.

Design/methodology/approach

In accordance with the purpose of the work, the methods are analytical interpretation of the scientific literature related to this problem as well as speculative explanations. The information base of the research is bibliometric publications dealing with impact, impact factor, discipline impact factor, and discipline susceptibility factor.

Findings

Examples of the DIF application and modification of the indicator are given. It is shown why research and university libraries need to use the DIF to evaluate serials in conditions of scarce funding for subscription to serial publications, even if open access is available. The role of the DIF for evaluating journals by authors of scientific papers when choosing a good and right journal for submitting a paper is also briefly discussed. An original indicator “symmetrical” to the DIF (the “discipline susceptibility factor”) and its differences from the DIF in terms of content and purpose of evaluation are also briefly presented.

Research limitations

The selection of publications for the information base of the research did not include those in which the DIF was only mentioned, used partially or not for its original purpose. Restrictions on the length of the article to be submitted in this special issue of the JDIS also caused exclusion even a number of completely relevant publications. Consideration of the DIF is not placed in the context of describing other derivatives from the Garfield impact factor.

Practical implications

An underrated bibliometric indicator, viz. the discipline impact factor is being promoted for the practical application. An original indicator “symmetrical” to DIF has been proposed in order of searching serial publications representing the external research fields that might fit for potential applications of the results of scientific activities obtained within the framework of the specific research field represented by the cited specialized journals. Both can be useful in research and university libraries in their endeavors to improve scientific information services. Also, both can be used for evaluating journals by authors of scientific papers when choosing a journal to submit a paper.

Originality/value

The article substantiates the need to evaluate scientific serial publications in library activities—even in conditions of access to huge and convenient databases (subscription packages) and open access to a large number of serial publications. It gives a mini-survey of the history of one of the methods of such evaluation, and offers an original method for evaluating scientific serial publications.
