Austin, Texas, November 3-9, 2006


Understanding emerging trends and patterns in science and technology is essential not only to scientists and engineers in their own fast-advancing fields but also to a wide variety of individuals and organizations who are also interested in tracking the development of thematic topics. In this article, we introduce a conceptual framework that extends an isolated citation mapping to a series of recursively applicable batch mode operators so that one can move along citation links back and forth in two directions. We describe the prototype that implements the forward expansion operator and analyze our experience with the CiteSeer metadata. In addition, we combine the forward expansion operators with information visualization.
