Abstract

A Geographic Information Retrieval (GIR) system for answering geographic queries has to cope with various information needs, which have a wide range of contexts and implicit requirements. A user, for example, who is looking for a place to spend his or her holidays certainly has a different understanding of distance than a user looking for a bar in the city he or she lives in. To get a better understanding of geographic information needs and their implications for GIR systems, we analysed real world (geographic) queries with regard to different facets of geographic references in queries. The results of this analysis are presented in this paper, the aim of which was a classification of the geographic aspects of information needs. We present empirical results and line out possible classification criteria, which could be helpful in designing GIR systems that are able to consider different semantics of geographic references in queries.
地理信息需求的特点
地理信息检索(GIR)系统需要处理各种不同的信息需求,这些信息需求具有广泛的背景和隐含的要求。例如,一个用户正在寻找一个度假的地方,与一个用户在他或她居住的城市寻找一个酒吧,他或她对距离的理解肯定不同。为了更好地理解地理信息需求及其对GIR系统的影响,我们分析了现实世界(地理)查询中关于地理参考的不同方面。本文提出了这一分析的结果,其目的是对信息需求的地理方面进行分类。我们提出了实证结果,并列出了可能的分类标准,这可能有助于设计能够在查询中考虑不同地理参考语义的GIR系统。
