The Building Of A Knowledge Base And The Generation Of Brief Report About Specific Domain

The work about construction of specific domain knowledge base and generationof briefreport, is put forward under the background that the people access toknowledge from the Internet is relatively difficult, its main target is to extractknowledge from a large number of web page, and organize a comprehensive report tothe user. The research work of this paper not only saves the time to search information,but also reprocess the information from Internet. We extract knowledge from theinformation, and construct the knowledge base in a specific way of knowledgerepresentation, finally generate comprehensive report to the user according to user’squestions.The research contents about construction of a specific domain knowledge baseand generation of briefreport mainly includes three aspects: the acquiring andprocessing original data, constructing knowledge base, generating briefreport. Thispaper has the following contribution in the three aspects of the work:First, this paper proposes a heuristic denoising method combined with statisticson the work of processing original data. This method can change the intensity of Webpage denoising by adjusting threshold, make the final Web page have completedcontent, simple structure,and not contain any noise. This Web page denoising methodis also significantly higher efficiency than the traditional denoising method based onheuristic rules.Second, this paper puts forward a new knowledge representation suitable for theresearch domain in constructing knowledge base. According to the differentknowledge type we design corresponding knowledge representation,including entitymeta-knowledeg and event meta-knowledge, construct two kinds of knowledge base,the entity meta-knowledge base contains234pieces of knowledge and the eventsknowledge base contains3158pieces of meta-knowledge. The two knowledge baseare convenient to automatic store and read knowledge，because they have simplestructure and hierarchy.Third, according to this research domain characteristic, this paper designs theprocess from builded knowledge base to comprehensive report. We can implementscomprehensive report generation system under the limited way of questions aboutcomputing cloud company.With the briefreport automatic generation system we can achieve the comprehensive report about the234computing cloud computingcompanies.That illustrates the research work of this paper is feasible.
