Ranking Refinement via Relevance Feedback in Geographic Information Retrieval

Recent evaluation results from Geographic Information Retrieval (GIR) indicate that current information retrieval methods are effective to retrieve relevant documents for geographic queries, but; they have severe difficulties to generate a pertinent ranking of them. Motivated by these results in tins paper we present a novel re-ranking method, which employs information obtained through a relevance feedback process to perform it ranking refinement. Performed experiments show that the proposed method allows to improve the generated ranking from a. traditional IR machine, as well as results from traditional re-ranking strategies such as query expansion via relevance feedback.
