Title

Improving the effectiveness of retrieval systems by information structures

Abstract

Describes a new information structure that is aimed at increasing the effectiveness of an information retrieval system. This structure is a manually constructed knowledge representation providing additional information to the retrieval process. To analyse the properties of this new structure, the framework of first-order theories (model theory) is used. The results show that the construction and maintenance of such a structure are easier than those of a thesaurus.
