Evaluating Geographic Information Retrieval

Abstract. The processing steps required for geographic information retrieval include many steps that are common to all forms of information retrieval, e.g. stopword filtering, stemming, vocabulary enrichment, understanding Booleans, and fluff removal. Only a few steps, in particular the detection of geographic entities and the assignment of bounding boxes to these, are specific to geographic IR. The paper presents the results of experiments designed to evaluate the geography-specificity of the GeoCLEF 2005 task, and suggests some methods to increase the sensitivity of the evaluation.
