An Efficient Approach to Learning Chinese Judgment Document Similarity Based on Knowledge Summarization
This work addresses the need for more accurate and efficient case reference in legal systems, though it appears incremental as it builds on existing methods like WMD with domain-specific adaptations.
The authors tackled the problem of computing semantic similarity between Chinese judgment documents by proposing a knowledge block summarization approach, which achieved higher accuracy and faster computation speed compared to traditional methods.
A previous similar case in common law systems can be used as a reference with respect to the current case such that identical situations can be treated similarly in every case. However, current approaches for judgment document similarity computation failed to capture the core semantics of judgment documents and therefore suffer from lower accuracy and higher computation complexity. In this paper, a knowledge block summarization based machine learning approach is proposed to compute the semantic similarity of Chinese judgment documents. By utilizing domain ontologies for judgment documents, the core semantics of Chinese judgment documents is summarized based on knowledge blocks. Then the WMD algorithm is used to calculate the similarity between knowledge blocks. At last, the related experiments were made to illustrate that our approach is very effective and efficient in achieving higher accuracy and faster computation speed in comparison with the traditional approaches.
