This paper presents the results obtained by our group at the GeoCLEF 2006. Our system used a method based on the expansion of index terms, which exploits WordNet synonyms and holonyms. This may help in finding implicit geographic information from text, particularly in the cases in which the indication of the containing geograph- ical entity is omitted. The system is based on the Lucene search engine. We submitted two kind of runs, one using WordNet to expand the index terms, the other without any expansion. Results show that expansion can improve recall in some cases, al- though a specific ranking function is needed in order to obtain better results in terms of precision. |
