This study investigates the ability of cluster visualization to help a user rapidly identify relevant documents. It provides added support for the truth of the Cluster Hypothesis on retrieved documents and shows that clustering of relevant documents is readily visible. The study then shows the visual eeect of a technique similar to relevance feedback and shows how to enhance that eeect to further help the user locate relevant material. A ranked list returned by a text search engine purports to present the documents in the order they are most likely to be relevant: the rst document is the best match for the user's query, the second is the next most likely to be helpful, and so on. We are interested in situations where this simple model breaks down|where the user is unable to nd enough relevant material in the rst or second screens of the list. In particular, we are interested in helping a searcher nd all of the relevant material in the top ranked list without forcing him or her to wade through all of the non-relevant material. Our approach is based on a combination of document clustering and vi-sualization. We have observed that when documents are clustered and their relationships are visually displayed, the relevant documents generally clump together in the visualization. In this study, we investigate several hypotheses related to this observation: 1. Clustering is useful for separating relevant and non-relevant documents. This hypothesis is critical to our work, but not at all novel or surprising 1
