AbstractCurrently, for educators and researchers, diagnosing the online interactions specifically related to knowledge and expertise exchanges is challenging. To address the problem, this paper describes a framework for the understanding and measurement of expertise presence in computer conferences. Expertise presence is defined as a persistent contribution of knowledge relevant to the purposes of the computer conferences. The paper includes a technique for measuring the strength of expertise presence from transcripts of computer conferences, and it also envisages a number of applications in online learning diagnosis and research. A case study of the application of the framework to the computer conferences of several online courses is discussed. © 2007 British Educational Communications and Technology Agency.
