Abstract

The web is increasingly being used by mobile users, and it is increasingly possible to accurately geo-position mobile users. In addition, increasing volumes of geo-tagged web content are becoming available. Further, indications are that a substantial fraction of web keyword queries target local content. When combined, these observations suggest that spatial keyword querying is important and indeed gaining in importance. A prototypical spatial keyword query takes a user location and user-supplied keywords as parameters and returns web content that is spatially and textually relevant to these parameters. The paper reviews key concepts related to spatial keyword querying and reviews recent proposals by the author and his colleagues for spatial keyword querying functionality that is easy to use, relevant to users, and can be supported efficiently.
地理标记网络内容的空间关键词查询
越来越多的移动用户开始使用网络,而对移动用户进行准确地理定位的可能性也越来越大。此外,带有地理标记的网络内容也越来越多。此外,有迹象表明,相当一部分网络关键词查询是针对本地内容的。综合这些观察结果来看,空间关键词查询非常重要,而且越来越重要。典型的空间关键词查询将用户位置和用户提供的关键词作为参数,并返回与这些参数在空间和文本上相关的网络内容。本文回顾了与空间关键词查询相关的关键概念,并评述了作者及其同事最近提出的空间关键词查询功能建议,这些建议易于使用,与用户相关,并能得到有效支持。
