1. 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 the natural language content by identifying latent logical terms 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 associated with 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, wherein the propagating of the at least one knowledge value generates transaction records in a transaction knowledgebase data structure; and perform a reasoning operation based on the transaction knowledgebase data structure, wherein the at least one knowledge value associated with each node in the logical parse hierarchical representation comprises a knowledge tuple having one or more supporting evidence measure knowledge values and a relevance knowledge value.
