pAlgorithm::VSM --- A pure-Perl implementation for constructing either a VSM or an LSA model of a software library/corpus and for using such models for retrieving document names from the library/corpus in response to the search words in a query. The module can also use pre-stored VSM or LSA models of a library/corpus for faster retrieval. The module has also been provided with methods for calculating precision and recall numbers for measuring the retrieval accuracy for a given library/corpus. 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 "VSM" in the subject line if you wish to write to the author.
