Abstract
Mechanisms are provided for modifying an ontology for use with a natural language processing (NLP) task. A model of the ontology is obtained that comprises nodes representing concepts of the ontology and edges between nodes representing relationships between associated nodes of the ontology. A spreading activation operation is performed on the model of the ontology with the spreading activation operation matching a portion of a textual source to a matching node of the model and identifying related nodes to the matching node through edges of the model associated with the matching node to thereby generate an activation network. The activation network is evaluated with regard to a chosen NLP task to determine a performance metric for the NLP task associated with the nodes of the model. Based on the results, one of the model or a configuration of the activation network may be modified.
