Abstract

We describe a document retrieval language which enables a user to better represent their requirements with respect to the desired documents to be retrieved. This language allows for a specification of the interrelationship between the desired attributes using linguistic quantifiers. This framework also supports a hierarchical formulation of queries. These features allow for an increased expressiveness in the queries that be handled by a retrieval system.
