Adenine: A Metadata Programming Language (2007)
Dennis Quan, David F. Huynh, Vineet Sinha, David Karger
Haystack (Huynh et al., 2002), our personal information repository, uses a shared metadata store and a system of agents for helping the user manage his or her information. Agents use the shared...
Metadata-supported Agent Infrastructure (2007)
Dennis Quan, David F. Huynh, Vineet Sinha, David Karger
Agents are often useful for allowing users to delegate tedious or complicated tasks to the system. In many systems, multiple agents work in concert to achieve desired objectives. In these...

The Message without the Medium: Unifying Modern Messaging Paradigms through the Semantic Web (2004)
Karun Bakshi, David R. Karger, Dennis Quan
Since its inception, the Internet has been a hotbed of successful communications channels, starting off with e-mail, Internet Relay Chat and Usenet newsgroups and more recently adding weblogs,...
What would it mean to blog on the semantic web (2004)
Abstract. The phenomenon known as Web logging (“blogging”) has helped realize an initial goal of the Web: to turn Web content consumers (i.e., end users) into Web content producers. As the...
User Interface Continuations (2003)
Dennis Quan, David Huynh, David R. Karger, Robert Miller
Dialog boxes that collect parameters for commands often create ephemeral, unnatural interruptions of a program’s normal execution flow, encouraging the user to complete the dialog box as quickly as...
Haystack: a platform for authoring end user semantic web applications (2003)
Dennis Quan, David Huynh, David R. Karger
The Web fulfilled a practical need of users in allowing them to conveniently author, browse and share content online. Similarly, we believe that Semantic Web technologies will be more quickly...
The role of context in question answering systems (2003)
Jimmy Lin, Dennis Quan, Vineet Sinha, Karun Bakshi, David Huynh, Boris Katz, ...
Despite recent advances in natural language question answering technology, the problem of designing effective user interfaces has been largely unexplored. We conducted a user study to investigate the...
Sticky notes for the semantic web (2003)
David R. Karger, Boris Katz, Jimmy Lin, Dennis Quan
Computer-based annotation is increasing in popularity as a mechanism for revising documents and sharing comments over the Internet. One reason behind this surge is that viewpoints, summaries, and...
