1. A computer-implemented method of preparing a set of documents to support information extraction, the method comprising:

  • defining a set of concept categories;

    defining a set of monadic relations associated with single concepts;

    defining a set of dyadic relations between concepts;

    defining a set of rules that allow extraction of monadic relations associated with concepts and dyadic relations between concepts;

    receiving a corpus containing documents;

    parsing the documents to identify concepts;

    extracting, by applying the set of rules to the parsed documents, concept-relation-concept triples, referred to as CRCs, and relation-concept pairs, referred to as RCs from the parsed documents; and

    incorporating the CRCs and the RCs into a data organization.
