Peer reviewedChen, Chaomei; Kuljis, Jasna – Journal of the American Society for Information Science and Technology, 2003
Discussion of knowledge domain visualization focuses on practical issues concerning modeling and visualizing scientific revolutions. Studies growth patterns of specialties derived from citation and cocitation data on string theory in physics, using the general framework of Thomas Kuhn's structure of scientific revolutions.

Chen, Chaomei; McCain, Katherine; White, Howard; Lin, Xia – Proceedings of the ASIST Annual Meeting, 2002
Investigates an integrated approach to scientometrics, or science mapping, with emphasis on the use of information visualization and animation techniques. Describes citation and cocitation patterns derived from articles published in the journal "Scientometrics", 1981-2001 and presents the growth of citation rates through an animation…

Peer reviewedChen, Chaomei; Paul, Ray J.; O'Keefe, Bob – Journal of the American Society for Information Science and Technology, 2001
Discusses the role of information visualization in modeling and representing intellectual structures associated with scientific disciplines and visualizes the domain of computer graphics based on bibliographic data from author cocitation patterns. Highlights include author cocitation maps, citation time lines, animation of a high-dimensional…

Peer reviewedChen, Chaomei; Cribbin, Timothy; Macredie, Robert; Morar, Sonali – Journal of the American Society for Information Science and Technology, 2002
Discusses information visualization and cocitation analysis and demonstrates the use of an integrative approach to visualizing and tracking the development of competing scientific paradigms. Assumes that a cluster of highly cited and cocited scientific publications in a cocitation network represents the core of a predominant scientific paradigm.…
