摘要
随着WWW的出现和发展,Internet上出现的信息迅速增长。如何从大量的信息中获取有用的信息,正成为信息领域的关键技术。传统的搜索引擎没有考虑不同用户的兴趣,因此搜索出来的结果往往无法满足不同用户的特定需求。提出一种用户兴趣模型,能够有效表示用户兴趣,并对传统搜索引擎的搜索结果进行匹配度计算,从而将符合用户兴趣的结果返回给用户。基于这种模型开发了一个基于用户兴趣的法律领域的搜索引擎MyLaw。
With the emergence and evolution of WWW, the information on the Internet has increased greatly. Retrieving useful information from a large amount of information has become a key technology in the information area. Traditional search engine do not take different user＇s interest into consideration, so the result they retrieved can＇t satisfy user＇s specified needs. A user profile model is proposed, which can effectively reflect user＇s interest, compute similarity of user＇s interest against the results retrieved by the traditional search engine and returns the results that match the user＇s interest to the user. Based on this model, MyLaw, a user interest based search engine of legal area, is developed.
