The role of automated subject switching in a distributed information network

Abstract

This article discusses some of the forces at work within today's online database environment which could lead to the emergence of a distributed information network. Several important modules in such a network are identified, including an automated subject switching module. Switching options include: exact matching, equivalency matchings and word- and phrase-stem matching. Research investigations, critical issues, and preliminary findings with regard to switching options and strategies are reported. It is anticipated that one of the primary benefits from automated subject switching will be much greater utlization of the online STI resource.
