【摘要】 大部分的网页中都含有地理位置信息,Web搜索引擎可以利用网页位置信息来为用户提供更好的搜索体验.同时,用户所在的位置也影响到搜索结果的准确性.但已有的搜索引擎不能很好地支持位置相关的搜索.针对这一问题,提出并建立了一个地理位置感知的Web搜索工具——LOSAA.LOSSA通过抽取网页中的首要地理位置,并结合用户所在位置和查询位置对Google搜索引擎的结果进行再排序,从而提高搜索结果的准确性.更多还原

【Abstract】 Most Web pages contain location information,which can be utilized by search engines to improve searching performance for users.Meanwhile,user location is also a factor that may influence the effectiveness of searching results.However,traditional search engines have little support in processing location-textual Web search.Aiming at solving this problem,in this paper we present and implement a location-sensitive Web search assistant called LOSSA(location-sensitive search assistant).LOSSA extracts the focused locations for each Web page,and re-rank search results returned by Google on the basis of user location and query locations.It is demonstrated that LOSSA is helpful to improve the effectiveness of location-textual Web queries.更多还原
