Identifying and grounding descriptions of places

Simon E. Overell, Stefan M. Rüger
2006 Workshop on Geographic Information Retrieval  
This paper outlines our plans to apply the co-occurrence models generated with Wikipedia to solve the problem of disambiguating place names in text using supervised learning techniques.  ...  In this paper we test the hypothesis Given a piece of text describing an object or concept our combined disambiguation method can disambiguate whether it is a place and ground it to a Getty Thesaurus of  ...  Data mining Wikipedia is slowly making its way into Geographic Information Retrieval with the XLDB group using it as a source for place names in GeoCLEF 2005 [2] .  ...
