Abstract
In this paper we identify location names that appear in queries written in Indonesian using geographic gazeeter. We built the gazeeter 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.
