Applying Geo-feedback to geographic information retrieval

Abstract

In this paper we identify location names that appear in queries written in Indonesian using geographic gazetteer. We built the gazetteer by collecting geographic information from a number of geographic resources. We translated an Indonesian query set into English using a machine translation technique. We also made an attempt to improve the retrieval effectiveness using a query expansion technique. The result shows that identifying locations in the queries and applying the query expansion technique can help improve the retrieval effectiveness for certain queries. © 2008 Springer-Verlag Berlin Heidelberg.
