title = "Relational data model in document hierarchical indexing",
abstract = "One of the problems of the development of document indexing and retrieval applications is the usage of hierarchies. In this paper we describe a method of automatic hierarchical indexing using the traditional relational data model. The main idea is to assign continuous numbers to the words (grammatical forms of the words) that characterize the nodes in the hierarchy (concept tree). One of the advantages of the proposed scheme is its simplicity. The system that implements such indexing scheme is described.",
