检索质量评价标准的研究与实例分析

Retrieval Research and Case Analysis of the Quality Evaluation Criteria

随着web2.0进一步推广与应用,广大用户通过网络查询所感兴趣的信息时都要借助搜索引擎来实现,但在搜索结果中有些是与用户所查询的信息相关的,有些信息是无关的,那些无关的信息在一定程度上影响了用户的搜索体验。通过对精确率与召回率等指标与实例的分析,在搜索系统推出结果之前,对性能进行测评,如果效果不够理想,则重新研究设计和改进搜索技术,以期达到理想的搜索性能。

With further application of web 2. 0,user information queries of interest are generally relied over the network using a search engine. Some search results are related to the information on user request,but other irrelevant information to a certain extent affect the user＇s search experience. Through precision and recall ratio to search systems before introducing the results,searching performance were evaluated,and if the results were less than ideal,the search technology would be re-examined and redesigned in order to achieve the desired search performance.
