Abstract : We present an evaluation of an information retrieval system designed for the 1997 TREC-6 Interactive Track; that is, Aspect Oriented Retrieval, or finding documents that cover all aspects of relevance to a given topic. Our system includes a basic search system, a task-specific aspect window, and a 3-D visualization of document and aspect relationships. We compare two versions of our system against ZPRISE, a baseline system provided by NIST. A study of 20 searchers shows significant differences between two classes of searchers, and supports several hypotheses about the design of an aspect oriented system. An interesting result is a likely correlation between structural visualization ability and facility with a 3-D visualization.
