METHOD FOR EXTRACTING SIGNATURE FROM PROBLEM RECORDS THROUGH UNSTRUCTURED AND STRUCTURED TEXT MAPPING, CLASSIFICATION AND RANKING

摘要

The structure attributes and unstructured attributes of a ticket are used to generate a problem signature. For structured attributes, correlation between field values is determined and fields with the highest weight are identified. For unstructured attributes, data mining techniques are applied to generate a plurality of keywords with a ranking for each ticket by identifying keywords, and commonly used acronyms and corpus variances. The set of structured attributes and the plurality of keywords from unstructured attributes form the signature of a given problem ticket.
