1. A case-based reasoning system, comprising:

  • a case base capable of storing a plurality of cases that each include one or more attributes, each of said attributes comprising a property having a value associated therewith, wherein each of said properties of said attributes has a match weight associated therewith and each value has a mismatch weight associated therewith, wherein match weights of attributes in different cases are separately specified, said plurality of cases including a selected case; and

    a search engine that, in response to receipt of an incident including one or more input terms that each have an absent weight associated therewith, scores the relative closeness of said selected case to said incident utilizing (1) the match weights of attributes in said selected case that match input terms in said incident, (2) the mismatch weight of each value for which the associated property has a matching input term and the value itself has no matching input term, and (3) the absent weight of each input term having no matching attribute in said selected case.
