Experiments on using fuzzy quantified sentences in adhoc retrieval

In this work we implement and evaluate a fuzzy approach to Information Retrieval whose query language incorporates fuzzy quantifiers. Fuzzy quantified sentences are suitable for imposing additional restrictions in the retrieval process which are not typical in classic information retrieval. Moreover, fuzzy quantifiers can be implemented in different relaxed ways leading to a wide range of methods for combining query terms. The large-scale evaluation conducted here shows clearly the practical benefits obtained in terms of retrieval performance. These empirical results strengthen previous theoretical works that already advanced the adequacy of fuzzy quantifiers for modeling information needs.
