Similarity analysis of legal judgments

In this paper, we have made an effort to propose approaches to find similar legal judgements by extending the popular techniques used in information retrieval and search engines. Legal judgements are complex in nature and refer other judgements. We have analyzed all-term, legalterm, co-citation and bibliographic coupling-based similarity methods to find similar judgements. The experimental results show that the legal-term cosine similarity method performs better than all-term cosine similarity method. Also, the results show that bibliographic coupling similarity method improves the performance over co-citation approach.
