Information searching method based on public security domain knowledge ontology model

Abstract

The invention discloses an information searching method based on a public security domain knowledge ontology model, belonging to the searching technical field of natural language controlled words in the public security domain. The method disclosed by the invention comprises the steps of 1) establishing an analysis data warehouse, and implementing cluster analysis for the analysis data warehouse to obtain six basic elements; 2) dividing data in the analysis data warehouse into six categories according to a cluster result; 3) clustering each category of the data to obtain an element dimension of each category of the basic elements; 4) clustering the data in each element dimension to obtain a classification property of the data; 5) determining names of the controlled word categories according to a clustering result, dividing the public security data into the corresponding controlled word categories to obtain a controlled work bank; 6) establishing multi-dimensional quote marks for each controlled word; 7) searching the controlled word which is related to an input word in the controlled word bank according to an index number. The invention can automatically search vocabularies which are related to the target vocabularies, and can solve the problem that hidden information in the public security industry is hard to use and relate.

Description

technical field [0001] The invention belongs to the technical field of searching natural language controlled words in the public security field, and relates to an information search method based on a knowledge ontology model in the public security field. Background technique [0002] With the rapid development of informatization means in the public security industry, there are a large number of databases and information system applications in the public security industry. However, due to the various forms of information processed by the public security industry, there are a large number of duplicate and related data. Existing systems and various types of police are searching When searching data, only words and their related texts that exactly match the search target can be found. In order to achieve a better search effect, expand the scope of search results, and find hidden correlations between information, so as to facilitate case detection. To this end, it is necessary to...
