Abstract

The use of the Yager's OWA operators within a flexible querying interface is discussed. The key issue is the adaptation of an OWA operator to the specifics of a user's query. Some well-known approaches to the manipulation of the weights vector are reconsidered and a new one is proposed that is simple and efficient.
