Abstract

This paper describes the summarization of textual material about locations in the context of a geo-spatial information display system. Both structured data and unstructured web pages are linked to maps. When the amount of associated textual data is large, it is organized and summarized before display. A hierarchical summarization framework, conditioned on the small space available for display, has been fully implemented. A case study is conducted on a fully implemented system to show how users interact with text in an integration context. Eye-tracking results are presented to illustrate and verify the observations in case study.
