Abstract

One or more embodiments of the invention provide a semantic search method and device based on a case event knowledge graph, and electronic equipment, and the method comprises the steps: firstly carrying out the preprocessing of a law case event question inputted by a user, and then carrying out the information extraction and information fusion of the description of the law case event question; classifying the description based on case event type tags, and outputting a semantic search graph with the case event type tags; performing sub-graph matching on the semantic search graph and a law case event knowledge graph, and outputting law case event answer data. According to the method, the semantic network is established for the user questions, and matching and reasoning are carried out in combination with the case event knowledge graph, so the search intention of the user can be accurately captured, answers meeting the search intention of the user are directly given, and legal questions of the user are practically solved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of knowledge graphs, and in particular to a semantic search method, device and electronic device based on case event knowledge graphs. Background technique [0002] With the development of technology, artificial intelligence is promoting the reform of the judiciary. In the face of massive judicial documents and other legal resources, if the machine can understand and recognize the case to a certain extent, it will liberate manpower to a large extent, and it will be used in judicial application scenarios such as searching for similar cases and accurately pushing similar cases. play an important role. [0003] Most of the traditional legal case event search systems are based on keyword matching technology or case event classification, and the returned results are mainly based on whether there are relevant legal keywords in the user input material or directly rough classification...
