1. A computer system comprising:

  • one or more processors which process program instructions;

    a memory device connected to said one or more processors; and

    program instructions residing in said memory device for distinguishing domain-specific terms from a list specific to a particular domain by extracting linguistic objects from a set of question-and-answer pairs wherein the linguistic objects include lexical answer types and answer entities, grouping the lexical answer types into a first set and grouping the answer entities into a second set, identifying distinguishing features of one or more corpora specific to a particular domain wherein the distinguishing features distinguish the lexical answer types in the first set from the answer entities in the second set, and classifying the domain-specific terms as either lexical answer type or answer entity based on the distinguishing features,wherein said program instructions further train a natural language classifier using the distinguishing features, and the classifying uses the natural language classifier.
