An Overview
of Microsoft Research I'll
give an informal overview of research efforts at Microsoft Research, focusing
on the Adaptive Systems and Interaction Group. Research in this group attempts
to enhance the user experience through the synthesis of innovations in machine
intelligence and human-computer interaction. Key projects include work on information
management, perception and memory, new input and visualization tecnhiques, mixed-initiative
interaction, and sensory fusion and learning. My own research is in information
retrieval, so many examples will come from that realm. Bringing
Order to the Web ... and Beyond In
this talk I will describe algorithmic and interface innovations developed to help
users organize information, in particular web searchresults. Today web searches
return a ranked list of best-matching pagesand users have to sift through these
long undifferentiated lists to find items of interest. An important mechanism
for facilitating information access in a wide variety of applications is a structured
knowledge hierarchy, such as those used by library classification systems and
more recently web directories like Yahoo! and LookSmart. Structures like these
can be used to automatically organize arbitrary web search results as well. Using
our system, a query about "saturn" will pages organized into those having
to do with automobiles, computer games, the planet, and a WWF wrestler. There
are two key technologies for accomplishing this: 1) developing models for hierarchically
classifying arbitrary text pages on-the-fly, and 2) building user interfaces for
taking advantage of the resulting structure. I will begin by talking about enhancements
to support vector machine (SVM) learning algorithms for text classification that
exploit hierarchical structure, and then describe how we developed and evaluated
a series of user interfaces to support structured search. Interfaces that show
results in context provide retrieval advantages of up to 50% over traditional
lists and arestrongly preferred by users. Susan
Dumais is a Senior Researcher in the Adaptive Systems and Interaction Group at
Microsoft Research where she works on algorithms and interfaces for improved information
access and management. Prior tojoining Microsoft Research in July 1997, she was
at Bellcore and Bell Labs for many years. She received a B.A. in Mathematics and
Psychology from Bates College and a PhD in Cognitive Psychology from Indiana University.
She has published widely in the areas of human-computer interaction and information
retrieval. Her current research focuses on text categorization using inductive
learning techniques, and collaborative information retrieval (a joint project
with Univ Washington, Boeing and RISO Labs). Previous research included well-known
work on Latent Semantic Indexing (a statistical method for concept-based retrieval),
combining search and navigation, individual differences, perceptual learning and
attention, and organizational impacts of new technology. Susan
is Chair of ACM's SIGIR group, and serves on the NRC Committee on Computing and
Communications Research to Enable Better Use of Information Technology in "Digital
Government". She serves on the editorial board of: ACM: Transactions on Information
Systems, ACM: Transactions on Human Computer Interaction, Human Computer Interaction,
Information Processing and Management, Information Retrieval, Hypertext, Encyclopedia
of Information Retrieval, and Annual Review of Information Science and Technology,
and is actively incolved on program committeesfor several conferences. She has
been a visiting faculty member at Stevens Institute of Technology, New York University,
and the Universityof Chicago. |
