Text extraction for determining emerging issues in vehicle warranty reporting

摘要

A method is provided for detecting trends in service repairs for vehicles. Service repair verbatims are accessed from a warranty database that includes information relating to an identified concern with the vehicle. A thesaurus of service repair related terms is provided. The service repair related terms are each associated with at least one of a component category, a concern category, a cause category, and a correction of repair category. Key terms are identified in each service repair verbatim that have an association with the service repair related terms in the thesaurus. The key terms are extracted from each of the service repair verbatims. A user selectively generates a report based on a key term in the component category and at least one other key term from at least one other category. The report identifies an aggregate number of service repair verbatims associated with the key terms selected by the user.
