Abstract

The invention discloses a legal provision precise searching and sequencing method based on a knowledge map. The method includes the following steps of S101, inputting a to-be-searched keyword; S102, obtaining a subject term matched with the to-be-searched keyword and an associated word of the subject term from a legal knowledge map model to form a subject term library; S103, dynamically generatingthe weight of a subject term and an associated word of the subject term in the subject term library of the same cause of action according to the association relationship between the subject term library and a core subject in the legal knowledge map model; S104, obtaining subset groups of the subject term library to sequentially form the subset groups with element numbers of m, m-1, m-2...2; S105,taking one subject term from each subset group to form a final subject term group for searching; S106, sequencing all the subset groups on the basis of the number and total weight of keywords in thefinal subject term group for searching; S107, conducting searching in a legal provision database by means of the subject term group selected after sequencing, and sequencing and displaying the searchresults.

Description

technical field [0001] The invention relates to a method for searching and sorting legal clauses, in particular to a method for precise retrieval of legal clauses based on a knowledge graph and prioritization of search results. Background technique [0002] It is particularly important to strengthen the construction of the legal system in China and promote the basic strategy of ruling the country by law. Administration by law is an important part of ruling the country by law. In various judicial cases, all cases must be decided in accordance with the law. In addition to relying on their own professional knowledge and experience, judicial personnel often need to search for legal provisions involved in pending cases. Accurate and efficient retrieval of legal provisions has become a judicial task. There is an urgent need for personnel to search for other legal provisions. [0003] With the popularization and efficient operation of artificial intelligence, knowledge graph, as a...
