Claim:
A method for document characterization, the method comprising: identifying, by a computer system, a plurality of candidate textual representations in a document; identifying, by a computer system, unambiguous textual representations from among the plurality of candidate textual representations, each unambiguous textual representation having a single concept associated therewith; identifying, by a computer system, ambiguous textual representations from among the plurality of candidate textual representations, each ambiguous textual representation having a plurality of concepts associated therewith; for each ambiguous textual representation: determining, by the computer system, that one of the plurality of concepts associated with the ambiguous textual representation is also associated with an unambiguous textual representation; and in response to determining that one of the plurality of concepts associated with the ambiguous representation is also associated with the unambiguous textual representation, pruning, by the computer system, concepts of the plurality of concepts other than the concept to which an unambiguous textual representation is mapped; and outputting a modified version of the document having a portion of the candidate textual representations corresponding to at least a portion of the list of concepts following pruning hyperlinked to supplemental materials relating to the at least a portion of the list of concepts.
