Ranking Refinement via Relevance Feedback in Geographic Information Retrieval

چکیده
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 this paper we present a novel re-ranking method, which employs information obtained through a relevance feedback process to perform a 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 as query expansion via relevance feedback.

متن کاملConcept Based Representations for Ranking in Geographic Information Retrieval
Geographic Information Retrieval (GIR) is a specialized Information Retrieval (IR) branch that deals with information related to geographical locations. Traditional IR engines are perfectly able to retrieve the majority of the relevant documents for most geographical queries, but they have severe difficulties generating a pertinent ranking of the retrieved results, which leads to poor performan...
متن کاملLearning filtering rulesets for ranking refinement in relevance feedback
In this paper we propose an approach for refining a document ranking by learning filtering rulesets through relevance feedback. This approach includes two important procedures. One is a filtering method, which can be incorporated into any kinds of information retrieval systems. The other is a learning algorithm to make a set of filtering rules, each of which specifies a condition to identify re...
