Linking Homogeneous Web-based Repositories

The eClass is an instrumented environment that automatically captures details of a lecture experience and provides effective multimedia-enhanced webbased interfaces for users to review the lecture. The CoWeb is a web-based service for collaborative authoring of web-based material. The eClass and CoWeb information repositories, when integrated, provide a persistent medium for collaborative learning. We present in this paper the results from a preliminary service that creates links automatically among those repositories. We experimented with data from a graduate course that had a manual linking service available. Results of an ad hoc evaluation indicate that most links were relevant and complement those created manually.
