Abstract

The focus of this work is on the development of a document retrieval language which attempts to enable users to better represent their requirements with respect to retrieved documents. We describe a framework for evaluating documents which allows, in the spirit of computing with words, a linguistic specification of the interrelationship between the desired attributes. This framework, which makes considerable use of the Ordered Weighted Averaging (OWA) operator, also supports a hierarchical structure which allows for an increased expressiveness of queries.
