Applied Semantics, Inc. unveiled the addition of four new taxonomies as extensions to its Auto-Categorizer product. The four taxonomies, supplementing the existing ODP (Open Directory Project) and International Press Telecommunications Council (IPTC) taxonomy portfolio, include: MeSH (Medical Subject Headings) based on the National Library of Medicine’s (NLM) controlled vocabulary thesaurus of more than 20,000 top-level headings used by NLM for indexing articles; the U.S. Department of Labor’s SIC (Standard Industrial Classification System); the UNSPSC (Universal Standard Products and Services Classification), a 13,000-plus category taxonomy for classifying products and services of, for buy- and sell-side catalogs; and an 800-category taxonomy consisting of country codes standardized around the ISO 3166 alpha-2 code schema, enhanced with U.S. states and major U.S. and international cities. These industry-standard taxonomies are “plug-and-play” modules that can be individually licensed to enhance Applied Semantics Auto-Categorizer.
