Automatic Data Extraction And Visual Analysis And Deduction In Court Judgment Documents

Since the 18 th National Congress of the Communist Party of China,China has adopted zero tolerance attitude towards duty crimes and made a fight against corruption for an important part of national governance.With the efforts of the vast number of anti-corruption staff,more and more crimes have been investigated.The problem is that a large number of crime cases require to invest more resources.In this situation,the Ministry of Science and Technology and the Ministry of Public Security have set up a major research project "Public Security Risk Prevention and Control and Emergency Technical Equipment".It aims at improving the efficiency of investigation through computer technology and realize the judgment of the situation of duty crimes so as to control of key high-incidence areas and reduce the duty crimes.The content of my research belongs to the project "Multi-modal Anti-corruption Case Characteristics Discovery and Prediction of the Development Trend of Corruption Cases",it is a sub-project of of "Public Security Risk Prevention and Control and Emergency Technical Equipment".The main research content is how to automatically collect judgments for the internet in my research.Then I use natural language processing technology to extract 27 kinds of key information of judgment documents and design the WEB system of situation analysis of duty crime cases and case simulation and other modules.As of March 2019,there are more than 70 000 000 judgment documents publicized on the internet.So we use the crawler technology to obtain the public judgment documents as the initial document data.After that,we use many kinds natural language processing algorithms,such as based on rules information extraction algorithm,named entity recognition and so on.Then we use MySQL database to store the extraction of multi-category information.On this basis,we design the WEB-side visual system for judgment document data analysis and situation research and deduction modules.Finally we do the system testing to achieve the system design requirements of the subject.
