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.

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as figure 1 As shown, the precise search and sorting method for legal provisions based on the knowledge map in Embodiment 1 of the present invention mainly includes the following steps:

[0034] S101, input keywords to be searched;

[0035] S102. Obtain from the legal knowledge map model the subject words that match the keywords to be searched and the associated words of the subject words to form a thesaurus; the associated words include: superordinate topics, subordinate topics, and label synonyms; wherein, the superordinate topics refer to the represented Topics with a large scope, ...
