Abstract

This paper introduces the concept of spatial filters as an approach to increasing the relevance of the information retrieved by users of mobile information systems. This approach applies post-query filters to remove results that are deemed not relevant given some aspect of a mobile individual's spatial behaviour. The aim is to reduce the volume of results returned to users of mobile information systems, to avoid the need for manual filtering. An opportunity for future research is to consider how these filters can be applied to the task of combining rankings based upon thematic and spatial criteria, for documents retrieved from unstructured or semi-structured collections, such as those handled by geographic information retrieval systems.
用于移动信息检索的空间滤波器
本文介绍了空间滤波器的概念,作为一种提高移动信息系统用户检索信息相关性的方法。此方法应用查询后过滤器来删除被认为与移动个体空间行为的某些方面不相关的结果。其目的是减少返回给移动信息系统用户的结果量,以避免手动过滤的需要。未来研究的一个机会是考虑如何将这些过滤器应用于从非结构化或半结构化集合中检索的文档(例如由地理信息检索系统处理的文档)的基于主题和空间标准的组合排名的任务。
