Embodiment Construction

[0044] The present invention will be further described below in conjunction with accompanying drawing.

[0045] see figure 1 , the method for constructing the public security knowledge map of the present invention, including:

[0046] Step 1: Carry out ontology modeling according to the data sources and business characteristics covered in the public security field. The modeling content includes: class and class hierarchy construction, relationship and relationship association construction, attribute and attribute-class association relationship construction. The construction method adopts the combination of top-down and bottom-up. include:

[0047] Step S11, use the top-down construction method to construct classes and class hierarchies: use the basic elements of public security "people, things, things, points, and organizations" as the basic classes, and then according to the characteristics of the data source and the actual business, start from the basic Start with a clas...

Abstract

The invention discloses a method for constructing a public safety knowledge map. The method comprises the following steps of 1 carrying out the ontology modeling according to data sources and businesscharacteristics covered by the public safety field; 2 carrying out knowledge extraction from that current public safety data source; 3 storing that extracted knowledge in a combine manner of a graphdatabase, a relational database and a document database; 4 fusing knowledge collected from each data source; 5 performing the knowledge processing on the knowledge map which is used to complete the knowledge fusion. The invention makes the knowledge covering the public safety field more comprehensive under the condition that the data source is sufficiently supported.

Description

technical field [0001] The invention relates to the field of public security and the field of semantic network, in particular to a method for constructing a public security knowledge map. Background technique [0002] With the development of big data and artificial intelligence, knowledge graph, as an important part of artificial intelligence technology, has been widely used in intelligent search, man-machine question answering, Personalized recommendation and other directions provide a technical basis for knowledge-based organization and intelligent applications in medical, financial and other fields. In essence, the knowledge graph is a huge semantic network graph, which describes various entities or concepts and their relationships that exist in the real world through nodes representing entities or concepts and edges representing relationships. [0003] With the in-depth application of big data technology in the field of public security, a new era has opened. By effecti...
