Flexible Search and Navigation using Faceted Metadata

Abstract

We have developed an innovative search interface that allows non-expert users to move through large informa- tion spaces in a flexible manner without feeling lost. The design goal was to offer users a browsing the shelves experience seamlessly integrated with focused search. Key to achieving our goal is the explicit exposure of hi- erarchical faceted metadata in a manner that is intuitive and inviting to users. After several iterations of design and testing, the usability results are strikingly positive. We believe our approach marks a major step forward in search user interfaces and can serve as a model for web-based collections of up to 100,000 items.
