The Application of Quantitative Methods in Assessing the Effectiveness of Litigation Legal Strategies - An Example of the Case Study Approach

In legal practice litigation cases, the selection of a litigation strategy significantly impacts both the litigation process and the overall outcome of the case. The study mainly applies quantitative methods to evaluate the effectiveness of legal strategies for litigation. We collect relevant legal strategy texts after analyzing relevant civil litigation cases in China. We then use text mining methods, such as regular expressions, jieba participles, and Word2Vec training word vectors, to refine high-frequency words in text data related to litigation legal strategies. This process establishes a quantitative evaluation index system for assessing the effectiveness of litigation legal strategies. We select litigation legal strategy cases as the evaluation object, utilizing the PMC index to determine and evaluate the effectiveness of each strategy. The sample litigation legal strategies have a mean PMC index of 6.69, indicating a good overall level. Only one strategy is considered acceptable, with the remaining 87.5% rated as good. Deficient litigation solutions and thought paths, with a mean value below 0.8, hinder the effectiveness of litigation legal strategies. We recommend optimizing and improving them to enhance their effectiveness.
