Deciphering cluster representations

There are several recent studies that propose search output clustering as an alternative representation method to ranked output. Users are provided with cluster representations instead of lists of titles and invited to make decisions on groups of documents. This paper discusses the diculties involved in representing clusters for usersÕ evaluation in a concise but easily interpretable form. The...

In this paper two distinct similarity measures in a document vector space, the distance-based and anglebased similarity measures, are compared, and a newly developed similarity measure based upon both the distance and angle strengths of two compared objects is presented. The concept of the iso-extent contour, which facilitates the understanding of the nature of the newly developed similarity me...

The study of interactive information retrieval (IR) has been a small but constant part of the Text REtrieval Conferences (TREC 1±8) from the beginning. The main arena for such work has been the Interactive Track (TREC 3±8). This report presents a bibliography of those e€orts together with a summary of the evolving experimental framework within which the studies took place. Published by Elsevier...

The results from a series of three experiments that used Text Retrieval Conference (TREC) data and TREC search topics are compared. These experiments each involved three novel user interfaces (one per experiment). User interfaces that made it easier for users to view text were found to improve recall in all three experiments. A distinction was found between a cluster of subjects (a majority of ...
