What can we learn from the legal provisions in judgment documents?

Abstract

So far, more than 2 million judgment documents represented in the same pattern and standard have come up in China, which can be viewed as a huge knowledge base. From 150 thousands judgment documents in 2012, authors extracted more than 4,000 legal provisions, obtained the combination relationship among the provisions, calculated their lapping relationship, and constructed their co-occurrence matrix and lapping matrix. Then, authors proposed four recommendation algorithms. Experimental results reveal that the proposed algorithms which are considered the combination and lapping relationship of legal provisions perform more precisely and more meaningfully than traditional similar case recommendation algorithms which are not considered the relationship of provisions.
