Strategy-Based Interactive Cluster Visualization For Information Retrieval, Anton Leuski, James Allan

Computer Science Department Faculty Publication Series

In this paper we investigate a general purpose interactive information organization system. The system organizes documents by placing them into 1-, 2-, or 3- dimensional space based on their similarity and a springembedding algorithm. We begin by developing a method for estimating the quality of the organization when it is applied to a set of documents returned in response to a query. We show how the relevant documents tend to clump together in space. We proceed by presenting amethod for measuring the amount of structure in the organization and explain how this knowledge can be used to refine the system. …
