Abstract

GeoCLEF ran as a regular track for the second time within the Cross\ud Language Evaluation Forum (CLEF) 2007. The purpose of GeoCLEF is to test\ud and evaluate cross-language geographic information retrieval (GIR): retrieval\ud for topics with a geographic specification. GeoCLEF 2007 consisted of two sub\ud tasks. A search task ran for the third time and a query classification task was\ud organized for the first. For the GeoCLEF 2007 search task, twenty-five search\ud topics were defined by the organizing groups for searching English, German,\ud Portuguese and Spanish document collections. All topics were translated into\ud English, Indonesian, Portuguese, Spanish and German. Several topics in 2007\ud were geographically challenging. Thirteen groups submitted 108 runs. The\ud groups used a variety of approaches. For the classification task, a query log\ud from a search engine was provided and the groups needed to identify the\ud queries with a geographic scope and the geographic components within the\ud local queries
