Users are provided with cluster representations instead of lists of titles and invited to make decisions on groups of documents. This paper discusses the diculties involved in representing clusters for usersÕ evaluation in a concise but easily interpretable form. The discussion is based on ®ndings and user feedback from a user study investigating the eectiveness of

The overall impression created by the experiment results and usersÕ feedback is that clusters cannot be relied on to consistently produce meaningful document groups that can easily be recognised by the users. They also seem to lead to unrealistic user expectations. Ó
