Research and Implementation of Dynamic Knowledge Based on Ontology
LV Lv · Computer Knowledge and Technology · 2009
Based on users' interested things to extract the related knowledge in web pages, and generate a dynamic knowledge base is an interesting, non-trivial problem. Two problems are involved: 1) extract users' interested things from web pages; 2) dynamic knowledge base maintenance. To solve these problems, firstly, use OWL to construct knowledge base which contains users' interested content, and then identify the related things in web pages using information extraction and ontology mapping method. In this process, new knowledge is also learned and is used to update the knowledge base. Finally, the knowledge base is used to annotate web pages. Experiment shows this method is effective and pragmatic.
