BBK-UFRGS@CLEF2009: Query Expansion of Geographic Place Names
Richard Flemmings, Joana Barros, André Pinto Geraldo, Viviane P. Moreira · 2009
For our first participation on CLEF, our aim was to compare plain information retrieval strategies and query expansion and emphasis of geographic terms. ANNIE was used to recognise geographic entities which were expanded using Google's Hierarchical List of Geographical Place Names. The idea was that the expansion would produce more accurate answers. The results have shown the opposite. Our best performing run was the baseline. Future work will include further experiments and a deeper analysis of our results in order to enable the design of a better performing strategy.
