The aim in information filtering is to provide users with a personalised selection of information, based on a description of their interest profile. These can be automatically generated or set by users. We can expect that users sometimes will want to be able to review their profiles even if they are system generated. We present a study of the effects of combining automatic profiling with explicit user involvement. Firstly, we wanted to explore if a machine-learned profile would benefit from being based on an initial explicit user profile. Secondly, we tested if profiles that provided better filtering also were better liked by users. Finally, we tested if users could make improvements to machine-learned profiles. We found that the initial set-up of a personal profile was effective, and yielded performance improvements even after feedback training. However, the study showed no correlation between users ratings of profiles and their filtering performance. Neither were there any conclusive evidence that users could improve on the system-generated profiles.
