Scorpion is a research project at OCLC that builds tools for automatic subject assignment by combining library science and information retrieval techniques. A thesis of Scorpion is that the Dewey Decimal Classification (Dewey) can be used to perform automatic subject assignment for electronic items. This article describes recent research to objectively evaluate the performance of Scorpion and some initial results from a comparison of Scorpion results with the human-assigned classifications in OCLC NetFirst.
