Method and device for excavating similar judgement documents based on big data

Abstract

The invention aims at providing a method and device for excavating similar judgement documents based on big data. The method for excavating similar judgement documents based on big data comprises obtaining a large number of judgement documents which are disclosed, and obtaining the causes of action of each judgement document; obtaining the text topic feature information with respect to the case of the judgement document and several keyword relevant messages with respect to the party disputing content and the party appealing content in the judgement document based on the text content of each judgement document, and establishing a text feature vector of the judgement document based on the text topic feature information and the several keyword relevant messages; updating a feature word library with respect to keywords based on the several keyword relevant messages, displaying each judgement document in the large number of judgement documents in a text feature vector manner effectively and accurately, updating the feature word library with respect to keywords, thereby obtaining similar judgement documents quickly, and improving the working efficiency of excavating similar judgement documents.

Description

technical field [0001] This application relates to the computer field, and in particular to a technology for mining similar judgment documents based on big data. Background technique [0002] With the rapid development of Internet technology, the text data information on the network shows explosive growth, however, it becomes more and more difficult to find a small amount of effective text data information among these massive text data information. For example, it is increasingly difficult and time-consuming to find effective text data information in systems with a large amount of text data information such as automatic question answering systems, intelligent retrieval systems, and mail screening systems. [0003] In the existing technology, in the court business scenario, before the judge makes the fact finding and judgment result of the case under trial, it needs to dig out effective similar judgment documents in advance or in real time. For example, the people's court co...
