A neural network model for documentary base self-organising and querying

The paper describes a connectionist architecture for an information retrieval system. The concept of a “dynamic” thesaurus is considered, in order to improve the construction of a documentary base and to perform associative information retrieval. The authors suggest a set of rules for activating cells in order to start an activation/propagation process, on which the associative information retrieval is based while a self-organising mechanism is also activated. These two notions allow one to develop automatic query reformulating and dynamic restructuring of the information base
