摘要
为了克服内容评价搜索策略算法"近视"和链接分析算法"主体偏移"的缺点,提出了一种使用内容评价搜索策略和链接分析策略结合的算法。使用的方法开发网络信息采集器能够极大地提高用户的检索速度,并能有效地限制检索领域,大大减小检索结果的信息冗余度,使用户能够快速获取其真正需要的信息。研究表明使用内容评价搜索策略和链接分析策略结合的算法开发网络信息采集器能够提高垂直搜索引擎快、精、准等方面的性能。
In order to overcome the ＂short- sighted＂ of Content -based Web Analysis Strategy and the ＂subject migration＂ of Link - Based Web Analysis Strategy, a new search strategy which combines Content - based Web Analysis Strategy with Link - based Web Analysis Strategy. is presented in this paper. The method can greatly improve the running speed of the system, diminish the redundancy of search result, and finally give out the finite information what user really wants. Research shows that the aggregator developed with this new strategy can greatly improve the speed, accuracy and efficiency of vertical search engine.
