The Profile Editor: Designing a direct manipulative tool for assembling profiles

Information filtering systems retrieve documents from document streams according to their users’ long-term information interests represented by so-called profiles. The Profile Editor proposed in this article allows the interactive, direct manipulative construction of profiles. It takes a set of ranked queries and compiles them into a single profile by cropping and re-ranking the queries’ results. The approach of manual profile generation is expected to lead to two advantages: a) Profile generation is expected to be much faster than feedback-based automatic profile generation and b) users’ confidence in their profiles should be higher because they are in control of their profiles. The Profile Editor is currently being implemented in the context of an Internet TV program guide, in which it will be evaluated during the next months.
