摘要
针对目前搜索引擎存在的一些问题,该文结合本体技术及Okapi-BM25算法,实现了一种个性化的搜索引擎;设计并实现了基于本体的用户兴趣模型;采用Silverlight技术进行界面的设计,增强了用户的视觉效果;使用Okapi-BM25算法结合兴趣模型对检索的结果进行过滤,提高了搜索结果的准确性;在界面与准确性上更好地满足了用户的需求.
To tackle problems in the present search engines,this paper proposes a personalized search engine by combining ontology technology and the Okapi-BM25 algorithm.An ontology based user interest-model is designed and realized,and Silverlight technology is adopted to design the user interface to enhance users' visual effect.The retrieval results are filtered using the Okapi-BM25 algorithm and the user interest-model to increase the search accuracy.Overall,the proposed search engine can better meet users' needs with respect to user interface and search accuracy.
