Abstract:

In order to make the focused crawler comprehensive and accurately access to information security knowledge required by education in the construction of information security educating resources, this paper proposes a knowledge aggregation framework for information security. It established information security ontology to provide highly specialized precise delimiting description to the field of focused crawler. The depth-first traversal method guided by the maximum correlation and the correlation analysis in the semantic layer of crawled web page can improve the accuracy of the crawling information by the focused crawler. Using the mixed crawling strategy combining the breadth-first search strategy with the calculation to the connecting degree can improve the effectiveness of the crawling information by the focused crawler. The experiment comparing with focused crawler based on the description of keywords verifies the effectiveness of the proposed method.

Key words: security ontology, security education, knowledge aggregation, focused crawler, information security
