Systems and methods for applying statistical inference techniques to knowledge representations

摘要

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.

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, wherein the elemental component comprises an elemental concept or an elemental concept relationship between two or more elemental concepts, and wherein estimating the relevance comprises estimating a frequency of occurrence in reference data of one or more labels associated with the elemental component, wherein the elemental component includes the elemental concept, wherein the relevance associated with the elemental component comprises a concept relevance associated with the elemental concept, wherein the one or more labels associated with the elemental component comprises a label associated with the elemental concept, and wherein estimating the frequency of occurrence in the reference data of the one or more labels associated with the elemental component comprises estimating a term frequency of the label within at least a portion of the reference data; and in response to determining that the relevance associated with the elemental component exceeds a relevance threshold, modifying the elemental data structure, wherein modifying the elemental data structure comprises:
adding the elemental component to the elemental data structure, andstoring 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.
