1. A computerized method for searching for text passages in text documents, comprising:

  • (a) parsing said text documents to obtain syntactic text information about said text documents;

    (b) processing said syntactic text information to obtain semantic text information about said text documents, wherein said processing is performed by a computer;

    (c) building said semantic text information into first semantic text networks;

    (d) linking said first semantic text networks to an ontology;

    wherein the ontology includes concepts and relationship slots, wherein each of the concepts defines an entity, and wherein each of the relationship slots defines a binary relation between two concepts;

    (e) generating second semantic text networks from said text passages; and

    (f) matching said first semantic text networks to second semantic text networks by specifying meanings of said text passages to find said text passages in said text documents.
