Abstract

One or more embodiments of this specification provide a semantic search method, device and electronic device based on legal knowledge graph. In response to receiving the description of the legal issue input by the user, preprocessing the description; performing element extraction on the preprocessed description, the element extraction includes the extraction of entity-relationship-entity triples, Construct a semantic search graph according to the entity-relationship-entity triple, set up a category label for the semantic search graph based on the type of laws and regulations, and output a semantic search graph with labels; compare the semantic search graph with the legal knowledge map Subgraph matching, using subgraphs with high matching degree as legal answer data. The present invention can accurately capture the user's search intention by establishing a semantic network for the user's question and combining the legal knowledge graph for matching and reasoning, thereby directly giving an answer that satisfies the user's search intention, and actually solving the user's legal problem.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of knowledge graphs, in particular to a semantic search method, device and electronic device based on legal knowledge graphs. Background technique [0002] With the development of science and technology, automated legal consulting services are playing an increasingly important role in alleviating the shortage of human legal service resources. In the process of public legal consultation, an efficient and accurate legal search system can provide accurate and comprehensive one-stop solutions for the public. [0003] Most of the traditional legal search systems are based on retrieval questioning keyword matching technology and sorting algorithms. The returned results are mainly based on whether keywords exist in the material, and it is impossible to know the true meaning of the user's search sentence. This often contradicts the user's demand for accurate and immediate results. Fo...
