Abstract

One or more embodiments of the invention provide a semantic search method and apparatus based on a legal knowledge graph, and an electronic device. The method comprises the steps: responding to the received description of the legal question input by the user, and preprocessing the description; performing element extraction on the preprocessed description, wherein the element extraction includes extraction of entity relationship entity triples; constructing a semantic search graph according to the entity relationship entity triples, establishing category labels for the semantic search graph based on law and regulation types, and outputting the semantic search graph with the labels; performing sub-graph matching on the semantic search graph and a legal knowledge graph, and taking the sub-graph with high matching degree as legal 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 legal 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 the legal questions of the user are practically solved.

Description

Technical field[0001]In this manual, one or more embodiments relate to the field of knowledge map, and more particularly to a semantic search method, apparatus, and electronic device based on legal knowledge.Background technique[0002]With the development of technology, the automated legal consulting services play an increasingly important role in alleviating the lack of artificial legal service resources. In the process of legal advice, an efficient and accurate legal search system can provide precise and comprehensive one-stop solutions for the people.[0003]Traditional legal search system is mostly based on retrieving question-based keyword matching techniques and sorting algorithms, the result is mainly based on whether there is a keyword in the material, and cannot know the true meaning of the user search statement. This is often contradictory with the user's precision and needs. For example, when searching "What are the types of civil cases?", Traditional search system presentin...
