Abstract:
We describe the design of an User Interface for a ranked output
Information Retrieval system that integrates querying, navigation and
visualization in a seamless fashion. Highlights of the system include the
following:
-- Using a visualization scheme, the interface provides visual
feedback to the user about how the query words influence the ranking
of retrieved documents.
-- By simple drag-and-drop operations of objects on the screen, the
interface facilitates a naive end-user in constructing complex
structured queries and in providing relevance feedback.
-- To suit the evolving information needs of the user, the
interface supports navigational features such as browsing
documents by specific authors and browsing the Table of Contents of
publications.
-- The interface integrates an online thesaurus which provides
words related to the query that can be used by the user to expand
the original query.
By providing a rich set of features, the interface coherently supports a
wide spectrum of information gathering tactics for different classes
of users.
