IPM-G: Enabling Collaborative Filtering Using Multi-Application Interest Models

He Interest Profile Manager (IPM) plays the central role in inferring user interest during document triage. The IPM collects information about interest-related activity from the potentially many triage applications. In this paper, we extend the IPM framework to enable community-based navigation using inferred user interests from information gathering tasks involving the use of multiple applications. We call IPM running on server, Global IPM (IPM-G), and IPM-G can generate similarity assessments, and thus recommendations, based on three different levels: tasks, documents, and annotations. As a result, CF methods can be applied to each level to get results at these three levels of granularity. By representing inferred interests based on the features of their tasks, documents, and annotations, we make possible six potential collaborative filtering (CF) modes in the IPM-G. This paper describes why collaborative filtering based on multi-application interest models is important, abstractly describes the representation of the interest models, and presents details of one of these filtering modes.
