1. A method for classifying software production incident tickets, the method comprising: extracting, by a processor, a plurality of keywords from an incident ticket; deriving, by the processor, a query vector corresponding to the incident ticket based on the plurality of keywords; and classifying, by the processor, the incident ticket into at least one of a positive mechanization incident ticket and a negative mechanization incident ticket based on a comparison of the query vector and a plurality of vectors derived from a plurality of past incident tickets, wherein the comparison comprises at least adjusting the size of query vector by populating the query vector with dummy keywords, such that the query vector is of the same size as a vector from the plurality of vectors with which the comparison is to be performed, and adjusting the placement of the keywords within the query vector such that the adjusted keywords correspond to the placements of similar keywords within the vector from the plurality of vectors, and wherein the plurality of vectors are derived based on a plurality of keywords, and their corresponding occurrences in the plurality of past incident tickets, wherein the adjusted keywords are in the same positions as the similar keywords within the vector from the plurality of vectors.
