 SIS is pleased to welcome Jill Freyne, a Postdoctoral
Researcher from the University College Dublin, Ireland,
for a School-wide Colloquium on Monday, April 23, 2007. Dr.
Freyne will discuss “Collaborative Web Search: Exploiting
User Activity for User Benefits.” The lecture
will take place from 3:00 to 4:00pm in Room 501 in
the IS Building, 135 North Bellefield Avenue.
Dr. Freyne will discuss how search engines continue
to struggle with the challenges such as vague queries;
impatient users; and an enormous and rapidly expanding
collection of unmoderated, heterogeneous documents. These
factors make for an extremely hostile search environment.
Conventional approaches to Web search -- those that
adopt a traditional, document-centric, information
retrieval perspective -- are limited by their refusal
to consider the past search behavior of users during
future search sessions.
Collaborative Web Search (CWS) seeks to exploit the
high degree of natural query repetition and result
selection regularity that is prevalent among communities
of searchers. CWS reuses the search experiences of
community members to promote results that have previously
been judged relevant for queries. This facilitates
a better response to the type of vague queries that
are commonplace in Web searching and allows a generic
search engine to adapt to the preferences of communities
of individuals.
Dr Jill Freyne is a postdoctoral researcher at the
Department of Computer Science in University College
Dublin. She received her PhD and BSc degrees from UCD,
and worked as part of the I-SPY research project which
focuses on personalized, community based Web search. She
has since worked as a Post Doctoral Researcher in the
Adaptive Information Cluster in the School of Computer
Science and Informatics working in the areas of social
support, annotations and digital graffiti.
This colloquium is presented by the Human-Centered
Computing Research Interest Group, the Advanced Information
Access Group, and the PAWS
Lab. |
