Entity Recognition in Natural Language Processing Systems

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:

• ingest a source terminology resource to generate a hierarchical representation of the source terminology resource comprising nodes for terms related to concepts in the source terminology resource;
• generate, for a node of the nodes in the hierarchical representation of the source terminology resource, a permutation of a corresponding term associated with the node;
• generate an expanded hierarchical representation of the source terminology resource based on the generated permutation;
• generate an enhanced dictionary data structure based on the expanded hierarchical representation;
• and
• output the enhanced dictionary data structure to an analytics engine to perform analysis of a corpus of information using the enhanced dictionary data structure.

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:
• ingest a source terminology resource to generate a hierarchical representation of the source terminology resource comprising nodes for terms related to concepts in the source terminology resource;
• generate, for a node of the nodes in the hierarchical representation of the source terminology resource, a permutation of a corresponding term associated with the node;
• generate an expanded hierarchical representation of the source terminology resource based on the generated permutation;
• generate an enhanced dictionary data structure based on the expanded hierarchical representation;
• and
• output the enhanced dictionary data structure to an analytics engine to perform analysis of a corpus of information using the enhanced dictionary data structure.
