Natural Language Processing Utilizing Propagation of Knowledge through Logical Parse Tree Structures

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• generate a logical parse hierarchical representation of a first parse of a natural language content by identifying latent logical operators within the first parse indicative of logical relationships between elements of the natural language content, wherein the logical parse hierarchical representation comprises nodes and edges linking nodes;
• associate at least one knowledge value with each node in the logical parse hierarchical representation;
• propagate the at least one knowledge value of at least a subset of the nodes in the logical parse hierarchical representation to one or more other nodes in the logical parse hierarchical representation based on propagation rules;
• and
• perform a reasoning operation on the logical parse hierarchical representation to generate a knowledge output indicative of knowledge associated with one or more of the logical relationships between elements of the natural language content.

An apparatus comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• generate a logical parse hierarchical representation of a first parse of a natural language content by identifying latent logical operators within the first parse indicative of logical relationships between elements of the natural language content, wherein the logical parse hierarchical representation comprises nodes and edges linking nodes;
• associate at least one knowledge value with each node in the logical parse hierarchical representation;
• propagate the at least one knowledge value of at least a subset of the nodes in the logical parse hierarchical representation to one or more other nodes in the logical parse hierarchical representation based on propagation rules;
• and
• perform a reasoning operation on the logical parse hierarchical representation to generate a knowledge output indicative of knowledge associated with one or more of the logical relationships between elements of the natural language content.
