If this makes your head swim, try reading the first couple of paragraphs (only!) in the Wikipedia article on TF-IDF document ranking: https://en.wikipedia.org/wiki/Tf–idf That URL contains non-ASCII characters, so it might be problematic; if it doesn't work, try this: https://en.wikipedia.org/wiki/Tf%E2%80%93idf Paul. -- Paul Hoffman <[email protected]> Systems Librarian Fenway Library Organization 550 Huntington Ave. Boston, MA 02115 (617) 442-2384 (FLO main number) _______________________________________________ Koha mailing list http://koha-community.org [email protected] https://lists.katipo.co.nz/mailman/listinfo/koha
