Explicit Query Diversification for Geographical Information Retrieval

摘要: In this paper we make a rst attempt to evaluate the po- tential of diversity in Geographical Information Retrieval task. This task represent an opportunity take advantage diversity, given that documents are not relevant only from thematic point view, but also spatially. A user GIR system may be interested results ge- ographically distributed and equally relevant. We attempted diversify explicitly, reformulating queries with meronyms places con- tained original queries, help geographical ontology. The obtained show theoretical improvement is possible, approach eective case do contain enough data.
