Abstract
A query translator translates a query between a graphical user interface and a knowledge representation system. The knowledge representation system reformulates the query and generates an access plan to access data requested by the query. The access plan utilizes several different protocols to access the query information located in dissimilar databases distributed throughout a network. The knowledge representation system generates the access plan by first processing the query through a world view which defines the information in conceptual terms that a human being would understand and then processes the query through a system/network view which redefines the query into network and database access information so that the data requested by the query can be located. Placing the world view and the system network view in the knowledge representation system enables real-time intelligence to be used in the search process by providing a feedback loop between the searched databases and the knowledge representation system.
