Embodiment Construction

[0041] see figure 1 , in an embodiment of the present invention, a method for constructing a dynamic legal event map oriented to the legal field, the method is used to construct a dynamic legal event map oriented to the legal field, the present invention requires the knowledge of legal experts to strictly define legal events, and then uses the knowledge Graph technology and event extraction technology, combined with probabilistic graph model to construct event graph from the perspective of multiple legal data sources.

[0042] A method for constructing a dynamic legal event map oriented to the legal field of the present invention comprises the following steps:

[0043] (1) Definition of dynamic legal event map:

[0044] In a narrow sense, a legal event refers to a legal fact in the legal field, a legal fact and an objective phenomenon that does not depend on the subjective will of the subject of rights; A legal fact of at least one character and no less than one action occur...

Abstract

The present invention discloses a method for constructing a dynamic legal event map oriented to the legal field. The present invention uses natural language processing technology to construct a dynamic legal event map oriented to the legal field. The method for constructing a dynamic legal event map has not yet appeared in the legal field; and Compared with the prior art, the smallest unit of the dynamic legal event map in the present invention is a legal event rather than an entity, and the constructed map is composed of legal events and the relationship between legal events; compared with traditional event extraction, the present invention The knowledge in the constructed dynamic legal event graph is dynamic, computable, and deducible, rather than simply extracting events. The present invention constructs a dynamic legal event map oriented to the legal field, combines the traditional knowledge map knowledge extraction technology and event mining technology to construct the map, and then models the legal event elements and the relationship between legal events in the legal event map Perform legal event graph measurement.

Description

technical field [0001] The present invention mainly relates to the field of natural language processing, in particular to a method for constructing a dynamic legal event graph facing the legal field. Background technique [0002] With the gradual improvement of the legal system in our country, the administrative regulations are becoming more and more perfect, and the legal awareness of citizens is constantly increasing. More and more legal texts and judgment documents are made public, digitized, and informatized, accumulating a large amount of text information in the legal field. By constructing a legal text corpus in the judicial field, and using natural language processing technology to mine out what users care about in a specific scene, a specific plot, a specific time range and a specific area, there is at least one role and no less than one action things are called events. Different from general events, legal events emphasize legal facts and objective phenomena indepe...
