METHOD AND SYSTEM FOR LINKING DATA SOURCES FOR PROCESSING COMPOSITE CONCEPTS

摘要

A computer-implemented method and system and computer-readable medium are disclosed for linking an ontology provided by a content service (i.e. category ontology) with a word expansion ontology (i.e. lexical ontology). A user may provide an input such as a voice command to an application. The voice command is processed by a natural language processing (NLP) engine to derive the user's intent and to extract relevant entities embodied in the command. The NLP engine may create a composite concept set containing multiple permutations of the concepts (entities extracted) and provide the composite concept set to a concept mapper. The concept mapper searches a mapping file and applies one or more scoring operations to determine a best match between the composite concept set and at least one category provided by the category ontology. The content service is searched using the category and the results are displayed to the user.
