Other cryptographic characteristics such as frequency distribution of classes of words and letters are used to allocate and retrieve the information in the knowledge base. The system also utilizes a high speed cryptographic filter to reduce computational overhead. A crypto-signature is computed in this filtering process to permit fast and efficient pattern matching access and to interface the virtual memory system. Interpretation of requests having insufficient information or ambiguities is achieved by the use of information theory concepts of entropy and key equivocation in conjunction with a conversational mode.The system also rewrites the knowledge provided by the user in a form of Extended-Microinstructions, that participate in the inductive mapping process and code generation for the desired secondary language. The Extended-Microinstructions define the structure, parameters, and order of execution of a series of general purpose procedures used in the mapping process of the natural language to the command set.Other References
