GeoCLEF is an evaluation initiative for testing queries with a geographic specification in large set of text documents. GeoCLEF ran a regular track for the third time within the Cross Language Evaluation Forum (CLEF) 2008. The purpose of GeoCLEF is to test and evaluate cross-language geographic information retrieval (GIR). GeoCLEF 2008 consisted of two sub tasks. A search task ran for the third time and a Wikipedia pilot task (GikiP) was organized for the first time. For the GeoCLEF 2008 search

The groups used a variety of approaches, including sample documents, named entity extraction and ontology based retrieval. The evaluation methodology and results are presented in the paper.
