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

摘要

Mechanisms are provided for processing logical relationships in natural language content. A logical parse of a first parse of a natural language content is generated by identifying latent logical operators within the first parse indicative of logical relationships between elements of the natural language content. The logical parse comprises nodes and edges linking nodes. At least one knowledge value is associated with each node in the logical parse. The at least one knowledge value of at least a subset of the nodes in the logical parse is propagated to one or more other nodes in the logical parse based on propagation rules. A reasoning operation is performed on the logical parse to generate a knowledge output indicative of knowledge associated with one or more of the logical relationships between elements of the natural language content.

1. A method, in a data processing system comprising a processor and a memory, for processing logical relationships in natural language content, the method comprising:
generating, by the data processing system, 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; associating, by the data processing system, at least one knowledge value with each node in the logical parse hierarchical representation; propagating, by the data processing system, 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 performing 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.
