Ontology-based intelligent retrieval system for information security event

Abstract

The invention designs and realizes an ontology-based intelligent retrieval system for an information security event, which is a system for performing information retrieval of the information security event based on an ontology, and contains knowledge from the field of information security. The goal of designing the system is to provide knowledge accumulation in the field of information security for a user, and the system has a certain intelligent semantic retrieval function, so that the user can obtain required information security event related knowledge and information. A design concept is that firstly, an initial information security event domain ontology is established based on OWL, then information security event domain related information is acquired, and a relationship between information security event domain concepts is extracted, thereby realizing automatic expansion of the information security event domain ontology; secondly, an inference rule is designed according to a semantic relationship of the information security event ontology, and the information security event ontology is inferred based on Jena; and finally, the query expansion and sorting are carried out based on the information security event ontology and semantic similarity calculation, thereby realizing semantic retrieval of the information security event.

Description

technical field [0001] The invention belongs to the technical category of information retrieval, in particular to an ontology-based intelligent retrieval system for information security events. The invention is oriented to the field of information security events, and can provide users with the functions of acquiring relevant knowledge of information security events and intelligent retrieval. Background technique [0002] With the rapid development of computer network technology, my country has made great progress in network construction. With the development of the information industry, the Internet and network information security issues have also become a hot issue of concern to the relevant government departments, major industries and leaders of enterprises and institutions. At present, the economic losses caused by the vulnerability of information systems in the world are increasing year by year, security problems are becoming more and more serious, and information abo...

AI Technical Summary

Problems solved by technology

First of all, most of the traditional information retrieval tools use keyword-based user demand acquisition mechanisms, which do not understand user needs enough and cannot achieve extended search, which will inevitably cause semantic loss and output a large amount of useless junk information. Not high enough to be retrieved by simple reasoning
