Relevance Ranking for Geographic IR

In this paper, we introduce a geographic similarity operator that computes the relatedness between two geographic places and describe how it is combined with textual ranking. The effectiveness of the geographic ranking is evaluated on the GeoCLEF 2005 collection. We considered various strategies for query formulation and for combining textual ant geographical ranking. For some queries, geographic ranking significantly improves results, while for other queries it does not have a positive impact.
