  • Patent number: 5257185
    Abstract: A knowledge system having a development configuration by which a knowledge engineer enters knowledge content into a database, and a user configuration employed by the end user to access the database for interactive learning, information retrieval, and problem solving in a specified subject area. The knowledge is organized by a hierarchy of topic nodes, with each node having an associated plurality of cross referenceable information units representing a variety of types, or categories, of information. The user can control the navigation path and information display sequence among information units in accordance with personal learning needs and style. One category can include a pattern of prompts and possible responses. The separation of knowledge content from program logic permits non-programmers to set up, modify, and maintain the knowledge content of the system.
