| 摘 要： | 元搜索引擎将为用户提供更全面的搜索结果信息,但在庞大的搜索结果中快速找到自己感兴趣的结果并非易事.针对查询结果合成问题,提出了一种基于用户兴趣的结果合成方法,在摘要法计算用户查询与查询结果相关度的基础上引入了词条等级和用户兴趣,实现了元搜索引擎的个性化.通过程序实现此算法,分别与单个搜索引擎以及其他几种结果合成算法比较,证明此算法保证了搜索结果的查全率,又提高了查准率,大大改善了用户检索效果和效率.

| Abstract: | The Meta-Search Engine provides more comprehensive information of searched results for users,but it is not easy to find the interested information in enormous searched results fast.For settling this problem,an algorithm of meta search results merging based on user profile is brought forward.It introduces the lemma rank and user profile on the basis of the Abstract algorithm which is used to estimate the correlation degree between the results and user query so realizes the individuation of the meta search en... |
