摘　　要：根据用户的"兴趣",从网页中提取相关的知识,并生成动态的知识库是一个有趣而且不简单的问题。主要有两个技术问题:1)如何从网页中提取用户感兴趣的内容;2)如何动态地维护知识库。要解决这些问题,首先用OWL手工构造用户"感兴趣内容"的知识库,通过信息提取和本体映射技术识别网页中相关的内容。这一过程同时也将学习和原来知识库相关的内容,成新的知识,修改旧的知识库,最后通过生成的本体对网页进行标注。实验表明这是个有效而且实用的方法。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.
