摘要
记者从发明人提供的背景信息中获得了以下引文：“在线搜索引擎的技术现状，通常涉及基于单词或基于短语的搜索，在检索文档(例如网页、图像、文件等)的能力方面是相当先进的。”响应查询的术语，通常使用查询中包含的关键字RD进行搜索和检索。虽然此类搜索引擎通常返回与查询的搜索术语（关键字）准确对应的结果，但SEARC H结果可能不反映用户的基本兴趣和目标。“此外，使用此类关键字搜索，搜索引擎可能返回太多的搜索结果和来自的搜索结果的有效质量，从而产生几个问题。首先，返回如此大量的结果，以至于用户不能在合理的时间段内审查所有的结果，或者在分配给用户审查的时间内审查所有的结果。第二，由于大量的结果，搜索提供者通常返回已经根据搜索提供者应用的一些标准，例如由G Oogle页面排名系统根据第三方提供的到所选网页(或网站)的链接的数量作为所选网页(或网站)重要性的指示而进行的搜索结果。
Abstract
Reporters obtained the following quote from the background information supplied by the inventors: “The current state of the art in online search engines, genera lly involving word-based or phrase-based searching, is reasonably advanced in it s ability to retrieve documents (e.g., web pages, images, files, etc.) that are responsive to the terms of a query, typically searched and retrieved using keywo rds contained in the query. While such search engines typically return results t hat accurately correspond to the search terms (keywords) of the query, the searc h results may not reflect the user’s underlying interests and goals. “Additionally, using such keyword searching, too many search results and an insu fficient quality of the search results from may be returned by the search engine , creating several problems. First, such a large number of results are returned that the user cannot review all of the results in a reasonable period of time, o r within the time allocated for review by the user. Second, because of the large number of results, search providers typically return results which have been ra nked according to some criteria applied by the search provider, such as by the G oogle page ranking system based upon the number of links to a selected web page (or website) provided by third parties as an indicator of the importance of the selected web page (or website).
