| 摘 要： | 目前许多用户查询与网页信息的时效性密切相关，但当前的搜索引擎在处理许多具有时间属性的查询时还不尽如人意。通过引入基于时间感知的用户查询理解、索引结构和页面排序算法，提出一种基于用户查询日志挖掘的时间感知搜索引擎模型，来克服当前主流搜索引擎在处理具有时效性查询时存在的不足在真实的Web环境下广泛进行的实验结果表明了该模型的有效性。

| Abstract: | Many of web pages have freshness and nowadays many users＇ queries are closely related to this freshness For current search engines, however, there are still some problems in handling many queries with time property. A new temporal-aware search engine model was presented, which introduces the user query understanding, index structure and page ranking algorithm based on the temporal-aware processing into architecture of search engine. This model aims at o- vercome the shortcoming of the traditional keyword-based search engine in dealing with the time-based queries. Exten- sive experiments are carried out in a real Web environment, and the experimental results show the effectiveness of the model. |
