  • (a) automatically segmenting said free text document into a plurality of sentences;

    (b) using a computer processor to retrieve a plurality of propositions by matching said sentences in a semantic mapping table created by domain experts through semantically annotating sentences from a corpus of related documents in a knowledge domain to propositions,(c) using a computer processor to retrieve a plurality of codes in a standard lexicon by matching said propositions to said codes created by a third party, in a code mapping table created by domain experts by annotating said propositions to said codes;

    wherein one or more of said matching codes from said standard lexicon represents at least a portion of the semantic content of said free text document.
