Abstract


With the rapid development of the World Wide Web , more and more organizations, companies and other information released software security flaws have been found on the World Wide Web . In this paper, based on the vertical search technology for software security defect information from the Internet , and further based on semantic annotation to extract the information used to build the software security flaws Knowledge Base . With vertical search and semantic annotation annotation techniques, and tools for software security defect information from the World Wide Web . The tool first design keyword training keywords in the field of software security defects ; then get the field Keywords design web filter ; the last filter design based on this site. Vertical search reptiles , crawling on the World Wide Web search software security defect information . A the vertical search crawlers tool combination of breadth-first search strategy based on Web topology and filter web filter algorithm based on keyword weight , as well as the optimal search strategy , the reptiles combined web filter can filter the field of non - software security web , can automatically multi-threaded download software security field of web pages ; design and Baidu search engine tools to get the information of software security defects ; realized based on the areas of Web content analysis algorithms keyword training tool , the tool for web filter keywords and its weight ; design and semantic annotation and parsing using JAXP - based semantic annotation results GATE Tools download page , the tool through GATE tool for semantic annotation of unstructured web information using JAXP technology marked parse , extract the safety defect information pages . The tool can be real-time information on the World Wide Web in the field of software security search crawling , and structured its information processing , provide data to support the basis for the knowledge base and analysis of software security vulnerabilities for building software security flaws .
