Embodiment Construction

[0033] Compare and match the characteristics of the case with the ontology information in the ontology case database in the legal field. Through ontology analysis, find relevant legal articles similar to the characteristics of the case in the ontology case database of laws and regulations, and extract the legal articles and related trial recommendations. The overall structure is as figure 1 shown.

[0034] A collection of criminal case and civil case judgment documents based on the important evidence in the court case trial process and massive data of due cases.

[0035] Store these documents in a local or network database or in a subfolder of the root directory.

[0036] Model the criminal case and summarize the characteristics of the case:

[0037] There are a total of 39 types of case characteristics, covering the semantics of the cause, process, and after-the-fact behavior of criminal acts.

[0038] According to the expert analysis of criminal attributes, we intend to d...

Abstract

The invention discloses a case retrieval method based on a genetic algorithm and a nearest neighbor algorithm. The method comprises the steps that S1, criminal case data is expressed and stored scientifically and effectively in a vector form; S2, a model established based on a GA-KNN method algorithm is used for inference; S3, an operation interface is provided for user access data through a creation-read-update-delete module of mass criminal case data; and S4, a neural network is utilized for modeling, and a judgment result of a judge is predicted. According to the method, an inference system based on evidence and cases is applied to a case trial process, and therefore case trial objectiveness can be effectively ensured; meanwhile, with the assistance of a decision making system, case trial justice can be effectively ensured, case trial efficiency can be improved, and therefore the method has theoretical creation and application creation value.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to a case retrieval method based on a genetic algorithm and a nearest neighbor algorithm. Background technique [0002] As the main body of case trial, the court has accumulated a lot of successful experience in many years of work, and has preserved a large amount of case intelligence information in digital form. At the same time, with the gradual deepening of the application of computer technology, the management and application strategies of these information are becoming more and more mature, especially after the application of various management information systems, the application and management capabilities of case intelligence information have been greatly improved. [0003] In terms of comprehensive mining and utilization of historical case information, some developed countries started research as early as the late 1980s. Relying on the development of their ad...
