Algorithm::TicketClusterer is a perl5 module for retrieving Excel-stored tickets that are most similar to a new ticket. Tickets are commonly used in software services industry and customer support businesses to record requests for service, product complaints, user feedback, and so on. Identifying old tickets similar to a new ticket is made challenging by the fact that folks who submit tickets often write them quickly and informally. The informal style of writing means that different people may use different colloquial terms to describe the same thing. And the quickness associated with their submission causes the tickets to frequently contain spelling and other errors such as conjoined words, fragmentation of long words, and so on. This module is an attempt at dealing with these challenges. That different people may use different words for the same thing is dealt with by using WordNet to expand the tickets with synonyms in order to ground the tickets in a common vocabulary. This module requires the following three modules: Spreadsheet::ParseExcel Spreadsheet::XLSX WordNet::QueryData the first for extracting information from the old-style Excel sheets that are commonly used for storing tickets, the second for extracting the same information from the new-style Excel sheets, and the third for interfacing with WordNet for extracting the synonyms and antonyms for the words in the tickets. For installation, do the usual perl Makefile.PL make make test make install if you have root access. If not, perl Makefile.PL prefix=/some/other/directory/ make make test make install Contact: Avinash Kak email: kak@purdue.edu Please place the string "TicketClusterer" in the subject line if you wish to write to the author.
