Search::VectorSpace Description
Search::VectorSpace is a very basic vector-space search engine. Search::VectorSpace is a very basic vector-space search engine.SYNOPSIS use Search::VectorSpace; my @docs = ...; my $engine = Search::VectorSpace->new( docs => @docs, threshold => .04); $engine->build_index(); while ( my $query = ) { my %results = $engine->search( $query ); print join "n", keys %results; }This module takes a list of documents (in English) and builds a simple in-memory search engine using a vector space model. Documents are stored as PDL objects, and after the initial indexing phase, the search should be very fast. This implementation applies a rudimentary stop list to filter out very common words, and uses a cosine measure to calculate document similarity. All documents above a user-configurable similarity threshold are returned. Requirements: · Perl
