Towards Fuzzy Spatial Reasoning in Geographic IR Systems

Steven Schockaert, Martine De Cock, Etienne E. Kerre
2006 Workshop on Geographic Information Retrieval  
In this contribution, we propose a framework to represent such spatial information, and show how new spatial relations may be deduced.  ...  Furthermore, we illustrate how this framework can be useful to increase the coverage of focused spatial information retrieval systems.  ...  Furthermore, we have sketched how this formalism can be used to increase the coverage of a focused IR system, relying on natural language descriptions of spatial constraints when address extraction or  ...

Geographic Information Retrieval and the World Wide Web: A Match Made in Electronic Space

David Johnson, Myke Gluck
1997 Cartographic Perspectives  
The goal of information retrieval is to match the user's needs to the information that is in the system. Retrieval of geographic information is a combination of both information and data retrieval.  ...  The final section of this article discusses how seven WWW GIR's solve the the problem of matching the user's information needs to the information in the system.  ...  Each retrieval system has a "criteria" for the items retrieved. In the IR system, relevance is the reason that the items are retrieved.  ...

Neighborhood restrictions in geographic IR

Steven Schockaert, Martine De Cock
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
Geographic information retrieval (GIR) systems allow users to specify a geographic context, in addition to a more traditional query, enabling the system to pinpoint interesting search results whose relevancy  ...  Unfortunately, many useful types of geographic restrictions are currently not supported in these systems, including restrictions that specify the neighborhood in which the business should be located.  ...  Towards the higher recall values, the gain in performance over the baseline systems somewhat decreases.  ...
