Placeless Documents: A Document Management System that Works the Way You Do
Keith Edwards, Xerox Palo Alto Research Center,

Traditional document storage systems -- including the file systems that most of us use -- are organized based on the needs of the system rather than the requirements of real world practice. They rely on long-lived hierarchies and impose artificial barriers between documents from different sources (files, the web, email, and so forth). The Placeless Documents Project is exploring ways to address these problems. The key notion in Placeless is that "properties" -- structured metadata on documents -- can be used to reflect multiple, overlapping work practices and can support flexible, dynamic organization and use of documents. In this talk, I'll describe the motivations and design of the Placeless Documents system, and discuss some of our experiences.

Biography: Keith Edwards is a member of the research staff at the Xerox PARC Computer Science Lab. His primary research interests include systems support for creating novel user interfaces and computer-supported collaboration. Keith has a Ph.D. in computer science from Georgia Tech.

Supporting Expertise Recommendations in Organizational Information Systems
David W. McDonald, Information and Computer Science, University of California, Irvine,

A long-standing problem in the development of groupware is the design and implementation of systems that support the subtleties of social interaction. This work explores the problem of finding "expertise" in an organization. An in-depth field study of expertise location in a medium sized software development company demonstrated that expertise is fundamentally a collaborative activity. People employ several different cognitive and social evaluations when identifying and selecting other individuals to pursue for expertise. The results from the field study were then used to inform the design of a system. I present an expertise recommender system that employs heuristics and information sources similar to those used by the field study participants.

Biography: David is completing a Ph.D. in Information and Computer Science at the University of California, Irvine. His dissertation research focuses on the problem of designing software that supports nuanced interaction among people. David has worked for AT&T Labs HCI research group, Apple Computer and Continuus Software Corporation. He holds a B.S. in Cognitive Psychology (UCLA) and an M.S. in Information and Computer Science (UCI).
