Geographic information retrieval: Modeling uncertainty of user's context
Fuzzy Sets and Systems, 2012Geographic information retrieval (GIR) is nowadays a hot research issue that involves the management of uncertainty and imprecision and the modeling of user preferences and context. Indexing the geographic content of documents implies dealing with the ambiguity, synonymy and homonymy of geographic names in texts.

Vague regions in Geographic Information Retrieval
SIGSPATIAL Special, 2011Vagueness abounds in natural language descriptions of geographical space. We frequently refer to place names for which no universally agreed boundaries exist (e.g. the Alps, Central London, Southern Europe) and describe spatial configurations using phrases that cannot indisputably be translated to hard constraints (e.g.

Learning to rank for geographic information retrieval
Proceedings of the 6th Workshop on Geographic Information Retrieval, 2010The task of Learning to Rank is currently getting increasing attention, providind a sound methodology for combining different sources of evidence. The goal is to design and apply machine learning methods to automatically learn a function from training data that can sort documents according to their relevance.

On metonymy recognition for geographic information retrieval
International Journal of Geographical Information Science, 2008Metonymically used location names (toponyms) refer to other, related entities and thus possess a meaning different from their literal, geographic sense. Metonymic uses are to be treated differently to improve the performance of geographic information retrieval (GIR).

Geographic information retrieval to suit immediate surroundings
Proceedings of the 17th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2009This paper proposes a highly effective geographic information retrieval method. It assesses the extent implied by place names in documents and then emphasizes place names that are highly specific in terms of identifying locations. Furthermore, the method also assesses the proximity between place names and keywords in each document and adjusts the ...

Geographic Information Retrieval by Topological, Geographical, and Conceptual Matching
International Conference on GeoSpatial Semantics, 2007Geographic Information Science community is recognized that modern Geographic Information Retrieval systems should support the processing of imprecise data distributed over heterogeneous repositories. This means the search for relevant geographic results for a geographic query (QG) even if the data sources do not contain a result that matches exactly ...

Text Meets Space: Geographic Content Extraction, Resolution and Information Retrieval
European Conference on Information Retrieval, 2020In this half-day tutorial, we will review the basic concepts of, methods for, and applications of geographic information retrieval, also showing some possible applications in fields such as the digital humanities. The tutorial is organized in four parts.

GIR@SIGSPATIAL, 2018
Geographic information retrieval (GIR) has largely been synonymous with spatial information retrieval. However, geographic information in text is not always explicitly, nor even implicitly, spatial, and when people are seeking geographic information, it ...

Geographic information retrieval (GIR)
Proceedings of the 27th annual international ACM SIGIR conference on Research and development in information retrieval, 2004Information retrieval systems in operation today for applications ranging from Digital Libraries to Web Search make very little use of two major dimensions of the data being searched: location and time. For many applications these dimensions can provide an intuitive and understandable visualization of search constraints and results.

Semantic feedback in geographical information retrieval systems
Proceedings of the 15th French-speaking conference on human-computer interaction on 15eme Conference Francophone sur l'Interaction Homme-Machine - IHM 2003, 2003Based on previous works on geographical information (GI) modeling and information retrieval, we report on the development of a human-system interface for the AntéServeur Géographique project. The AntéServeur project is a middleware system that implements a framework for retrieving geographical data of heterogeneous nature.
