Abstract

Scorpion is a research project at OCLC exploring the indexing and cataloguing of electronic resources. It focuses on building tools for automatic subject recognition based on the DDC. Dewey is used to classify any term and denote subject heading. The resources to be catalogued are treated as queries against a special Deqey database that returns a ranked list of potential subjects. Gives an overview of Scorpion and indicates future developments
