Visual interface for textual information retrieval systems
Aravindan Veerasamy, Scott E. Hudson, Shamkant B. Navathe · 1995
A prototype user interface implementation for text information retrieval system is described. Using a visualization scheme, the interface provides visual feedback to the user about how the query words influence the ranking of retrieved documents. The interface also helps the user in constructing complex structured queries by simple drag-and-drop operations. An intuitive model where the user classifies the information provided to him/her as being positive and negative aids him/her in supplying rich relevance feedback information to the system. Our prototype interface has been built on top of INQUERY [Callan et al ., 1992]. Preliminary experience with the interface shows it to be a valuable tool in aiding the interactive search process between the user and the system. To test the effectiveness of the interface, we plan to conduct studies on users with real information need searching a large corpus of articles.
