The Semantic Model in Information Retrieval

  • Jean Tague


Infological models of information systems represent a user’s conception of the real-world environment which is to be captured by the system. As such, they provide a basis for the design of the human-system interface. A number of models have been proposed for information retrieval systems: the Boolean model, the vector space model, and the relational model. In this paper, another model, the semantic model comes from database theory and is, in fact, an extension of that model. However, it provides a number of features which make it more powerful and expressive than these earlier models of retrieval systems. The implementation of the semantic model in an experimental information retrieval system which permits users to build their own interface is described.
