    Abstract: A method, system, and computer program product for storing and managing a knowledge profile are described. The knowledge is stored in knowledge units representative of unconstrained natural language (NL). Any given knowledge unit is associatable with at least one other knowledge unit with the given knowledge unit being a context knowledge unit, and the at least one other knowledge unit being a detail knowledge unit of the associated context knowledge unit, and such that every given context knowledge unit that has at least one associated detail knowledge unit satisfies a NL relationship there-between that corresponds to one of the NL-expressible forms of the NL word “have”. The profile includes a core set of knowledge units for a core vocabulary of words, at least some of which are associated with knowledge units to provide a basic meaning of the associated words. The profile further includes a core set of knowledge units for core processing and core parsing NL-expressible knowledge.

  • Patent number: 5432934
    Abstract: An access restriction interface system for use in a computer system of the sort comprising an operating environment and an application program and user interface apparatus, wherein the access restriction system is adapted to limit user access to the computer system by restricting user input through the user interface apparatus and computer output through the user interface apparatus. Preferably the access restriction system comprises a workspace hierarchy characterized by at least one top-level workspace and at least one lower level workspace on which items may be positioned; at least one class hierarchy for items and attributes of items positioned in one or more of the workspaces, the class hierarchy being characterized by a base class and one or more lower level classes; user restrictions selectively assignable to one or more of the workspaces and implemented in the workspace hierarchy; and class restrictions selectively assignable to one or more of the classes and implemented in the class hierarchy.
