Knowledge-Rich Interfaces for Retrieval in Diagonal Libraries
Northwestern University

The proliferation of digital libraries and online media archives has highlighted the need for new retrieval systems that effectively mediate between the retrieval needs of users and available materials. While the information retrieval research community has focused their efforts on improving the effectiveness of intelligent query-based approaches, there is increasing interest in systems that that allow users to browse through media collections on their own.

This talk will discuss a new retrieval interface that allows users to browse through collections to find materials that meet their particular retrieval needs. The quality of any browsing-based system depends primarily on the quality of the browsing space that is provided to its users. In this system, users interact with a collection by browsing through the subject terms that are used to catalog collection materials. These subject terms, which are collectively called a thesaurus, are organized by a new knowledge structure that is introduced in this research called an Expectation Package. Expectation Packages group together subject terms based on cognitive science theories of memory organization, and capture the common sense knowledge necessary to facilitate the browsing process. An example application of this interface will be described, which the Library of Congress Thesaurus for Graphic Materials to provide access to online image collections.

Refreshments will be served immediately before the talk at 3:30pm.
Gordon is a candidate for an Institute of Cognitive Science faculty position.


The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
