An information retrieval system implemented as a virtual data base management system which uses a knowledge base management system to provide a problem-oriented conceptual schema for one or more standard data base management systems. In the conceptual schema, a hierarchy of concepts is used to organize individual objects. A classifier determines which concepts an individual object is a representative of and determines the relationship of new concepts to existing concepts. The use of a knowledge base with a classifier permits conversion of queries into concepts and detection of changes in the relationships between individual objects and the concepts. A window-based user interface permits flexible and experimental access to the information. Special features of the user interface permit the user to specify conversion of a query into a concept, to establish monitors to detect such changes, and to define a query by specifying a portion of a graph.

Interactive data analysis employing a knowledge base

Interactive data analysis apparatus employing a knowledge base

Apparatus and methods for integrating a knowledge base management system with a data base system. The knowledge base management system employs compositional descriptions which describe information in terms of concepts. A translation component of the apparatus translates compositional descriptions into data base queries, so that information matching a compositional description may be retrieved from the data base. The translation component further permits display of the retrieved data in terms of the compositional description. The returned information can be automatically integrated into the knowledge base, either item by item or on the basis of the compositional description which was used to return the information.
