A Framework for Linguistic and Hierarchical Queries in Document Retrieval
We describe a document retrieval language which enables user’s to bet-ter represent their requirements with respect to the desired documents to be re-trieve. This language allows for a specification of the interrelationship between the desired attributes using linguistic quantifiers. This framework also supports a hier-archical formulation of queries. These features allow for an increased expressiveness in the queries that be handled by a retrieval system.
