Tutorial 29

Interface Issues and Interaction Strategies for Information Retrieval Systems

Scott Henninger, University of Nebraska
Nick Belkin, Rutgers University

Monday, May 8

Objective

Participants will learn (1) interface issues that arise when developing information retrieval systems, (2) that systems must be designed to accommodate the user's evolving understanding of the information need, (3) to evaluate a retrieval system for effectively supporting dynamic information needs, and (4) concrete design guidelines that can help in developing effective retrieval systems.

Content

This tutorial presents the key issues involved in use and design of effective interfacesto information retrieval systems. The process of satisfying information needs is analyzed as a problem solving activity in which users learn and refine their needs as they interact with a repository. Retrieval techniques are reviewed to provide sufficient background on designing a retrieval system, but the tutorial focuses on the design of interaction strategies and interfaces that support the process of satisfying information needs. Current systems are analyzed in terms of key interface and interaction techniques such as querying, browsing, and relevance feedback. The tutorial discusses the impact of information seeking strategies on the search process and what is needed to more effectively support the retrieval process. Retrieval system evaluation techniques are discussed in terms of their implications for users. A set of design guidelines and user-centered strategies for retrieval systems is outlined.

Audience

This introductory-level tutorial is for researchers and practitioners interested in designing interfaces for information retrieval systems. No prior knowledge of information retrieval techniques is required.

Presentation

Lecture, video, demonstration
