Abstract

Conceptual structures which can be used to represent any knowledge that can be represented by frames/units. Its realization, in a software program called Unit Interface, provides a method of storing frame/unit data in conceptual structures and algorithms for accessing that data when stored in conceptual structures as if it were a frame/unit or collection of them.

Claims

1. A method of operating a data processing system having memory means and processor means coupled to said memory means comprising,

storing concept data, relation data, calculation function code bits, knowledge representation function code bits and symbolic access code bits in said memory means,

utilizing said processor means to access symbolic access code bits in order to acquire knowledge representation frame code bits that are related to said accessed symbolic access code bits, wherein said knowledge representation frame code bits represent storage addresses of said memory means for related concept data, relation data and calculation function code bits, and

employing said processor means so that said processor means utilizes said acquired knowledge representation frame code bits to obtain said related concept data, relation data and calculation function code bits from said memory means.

2. A method as claimed in claim 1 wherein said data processing system comprises viewing means comprising the further step of utilizing said processor means to link said concept data and said relation data into conceptual graphs that are viewable on said viewing means.

3. A method as claimed in claim 1 wherein said data processing system comprises viewing means comprising the further step of utilizing said processor means to link concept data and calculation function code bits into data flow graphs that are viewable on said viewing means.

4. A method as claimed in claim 1 wherein said data processing system further comprises a viewing means and includes the further step of utilizing said processor means to link said concept data, relation data and calculation function code bits into bound data flow graphs that are viewable on said viewing means.

5. A method as claimed in claim 1 wherein said data processing system comprises viewing means comprising the further step of utilizing said processor means to link concept data, relation data and calculation function code bits into a type lattice that is viewable on said viewing means.
