A model of facet information retrieval within the collection of scientific materials

The authors describe the model of information retrieval within the collection of scientific materials utilizing the technology of adaptive facet navigation. A registered user creates the structured formal annotation for informational object while entering it into the database. Subsequently a special program converts the structured formal annotation into the object's facet formula. Generation of search request is conducted as a sequence of iterations, where search request is adjusted in dialogue mode by using both direct and associative links between informational objects. A formal model is used to develop realization model, where visual interface shows content of the collection of scientific materials and serves as suitable tool for generation of search requests.
