DFKI-LT - Ontology-based Query Construction for GeoCLEF
Ontology-based Query Construction for GeoCLEF
2 CLEF 2008 Working Notes, Aarhus, Denmark, Springer Verlag, 2008
This paper describes our participation in GeoCLEF. Being different from the traditional information retrieval, we focus more on the query expansion instead of document ranking. We parse each topic into the event part and the geographic part and use different ontologies to expand both parts respectively. The results show great advantages of our strategy for this task.
