SYSTEMS AND METHODS FOR APPLYING STATISTICAL INFERENCE TECHNIQUES TO KNOWLEDGE REPRESENTATIONS
First Claim
1. A method of modifying a computer-readable elemental data structure, the method comprising:
- estimating, using at least one processor executing stored program instructions, a relevance associated with an elemental component of the elemental data structure, estimating the relevance comprising estimating a frequency of occurrence in reference data of one or more labels associated with the elemental component; and
modifying the elemental data structure, comprising storing the relevance in data associated with the elemental component;
wherein the elemental component is encoded as a computer-readable data structure storing the data associated with the elemental component.

Abstract
Techniques for analyzing and synthesizing complex knowledge representations (KRs) may utilize an atomic knowledge representation model including both an elemental data structure and knowledge processing rules stored as machine-readable data and/or programming instructions. One or more of the knowledge processing rules may be applied to analyze an input complex KR to deconstruct its complex concepts and/or concept relationships to elemental concepts and/or concept relationships to be included in the elemental data structure. One or more of the knowledge processing rules may be applied to synthesize an output complex KR from the stored elemental data structure in accordance with context information. Methods of populating an elemental data structure and methods of synthesizing a complex KR from the elemental data structure may rely on statistical inference techniques.
