Judgement document-based structured processing method

Abstract

The invention relates to a judgement document-based structured processing method. According to the method, a natural language processing technology and an advanced machine learning technology are adopted to automatically realize case type classification on the basis of keyword extraction of brief texts, so that structured processing is carried out through constructing case hierarchical structuresand designing an extraction rule. Through constructing and extending a related lexicon, segmenting a judgment document module, designing and determining a cluster number K and an initial cluster center, and taking an increment of a word weight as second feature selection, the improvement of a kmeans cluster algorithm is realized, and class labels of cases are obtained; and through creating different hierarchical frameworks according to different case types and combining the designed extraction rule, structured processing of judgement documents is obtained. The method is capable of rapidly realizing the structured processing of judgement documents.

Description

technical field [0001] The invention relates to the technical field of structured processing of text data, in particular to a structured processing method based on referee documents. Background technique [0002] With the advancement of judicial reform, the depth and breadth of my country's judicial reform are also constantly expanding, and the ideas of democracy and the rule of law are slowly gaining popularity among the people. Among them, the online disclosure of judgment documents is a good example. Up to now, the number of judgment documents published on the Internet has reached more than 30 million. People can freely consult and download judgment documents through the Internet, which means better Protect the public's right to know and participate, enhance the image of the court's judicial justice, and establish judicial authority. The published judgment documents information is currently mainly presented in the form of Internet webpages. Although the case judgment doc...

Problems solved by technology

[0004] The structured processing of judgment documents is the premise of data analysis and in-depth mining of judicial cases. It not only requires mature big data mining technology, but also needs to formulate data processing services in the judicial field; the current mainstream and common information extraction techniques are divided into statistics and There are two types of rules. Statistics-based methods often have low accuracy in structured processing results in a specific field. The specific field has relatively special writing characteristics and cannot be directly transplanted to other fields.
