ASIST Special Interest Group - Classification Research - Studies the fundamental principles, underlying processes, and analytic constructs of classification schemes and procedures by humans or automata.

Automatic Categorization of Magazine Articles - Research paper discussing automatic categorization of magazine articles with broad subject descriptors. Focuses upon the following aspects of text classification: effective selection of feature words and proper names that reflect the main topics of the text, and training of text classifiers.

Classification Society - Scientific organization studying classification and clustering, including systematic methods for creating classification schemes from unstructured data. Tied to Class-L list maintained at State University of New York at Stony Brook.

Controlled Vocabulary - Describes how controlled vocabularies are useful in describing images and information for classifying content in electronic databases. Links to sample hierarchies and controlled vocabularies. Also features links to related resources.

Delphi Group Taxonomy and Content Classification Report - Examines software segment for taxonomy management.

DELTA: Description Language for Taxonomy - A flexible format for encoding taxonomic descriptions for computer processing, intended for biology but with broad applications. It can be used to produce natural-language descriptions, conventional or interactive keys, classifications, and information-retrieval systems.

Flamenco Project - Investigates how to effectively incorporate large, faceted category hierarchies into information access user interfaces.

International Federation of Classification Societies - A federation of national, regional, and linguistically-based classification societies whose aims are to further knowledge classification research.

MeURLin: URL-based Classification of Web Pages - Project that attempts to classify web pages based solely on their URL. A functional demo is included.

Ontological Engineering - About two dozen links collected by the ontology project at the philosophy department of the State University of New York at Buffalo, with emphasis on artificial intelligence and the Internet.

Project Aristotle - Projects, research, products and services investigating or demonstrating automated Web categorization. Some prototypes and demos are available.

Taxonomy Warehouse - Directory of taxonomies, thesauri, classification schemes, and other authority files, plus information on how to license the taxonomies. Features search, browse and alert service.

Crosstraining: Learning probabilistic mappings between topics - Introduces a general semi-supervised learning framework called cross-training which can exploit knowledge about label assignments in one taxonomy B to make better inferences about label assignments in another taxonomy A. [PDF] (August, 2003)
