We develop a query algebra that supports efficient assertion retrieval--a natural extension of instance retrieval. The algebra is based on previously developed techniques for index...

Conventional operators for data retrieval are either based on exact matching or on total order relationship among elements. Neither of them is appropriate to manage complex data, s...
This paper presents an algebraic formalism for reasoning on finite increasing sequences over Boolean algebras in general and on generalizations of Rough Set concepts in particular...
This paper considers the problem of adding list as a type constructor to an object-oriented data model. In particular, we are concerned with how lists in a database can be constru...
This paper introduces a novel framework for the accurate retrieval of relational concepts from huge texts. Prior to retrieval, all sentences are annotated with predicate argument ...
