Claim 8:
9. A method of classifying a maintenance record for a machine, the method comprising:
receiving the maintenance record including maintenance event information expressed as a collection of terms of interest in engineering jargon related to the machine, at least some of the engineering jargon abbreviated in maintenance record;
normalizing the terms of interest to their non-abbreviated, dictionary form;
accessing a database of authoritative engineering information from electronic documents, the authoritative engineering information expressed textually and indexed by class of a plurality of classes;
weighted scoring the authoritative engineering information that uses one or more of the terms of interest represented in the weighted scoring by uniqueness scores inversely related to frequency of the terms of interest across the plurality of classes to which the authoritative engineering information is indexed;
determining matching authoritative engineering information for the maintenance event information based on the weighted scoring; and
labeling the maintenance record with the class to which the matching authoritative engineering information is indexed, and thereby classifying the maintenance record into the class.
