[CS Undergrad-research-interest] CS Talk about information retrieval, Wed 04/28, 3:30pm HFH1132

[Phillip Conrad]

Here's a talk about techniques for retrieving information from the web (as
well as corporate intranets) where you may have very little advance
knowledge of the "structure, scope, and contents of the information
sources".

Also, IBM India Research Lab is hiring---in case you are interested in a
change of scenery, you are invited to bring your resumes. :-)

Regards,
Phill

UCSB COMPUTER SCIENCE DEPARTMENT PRESENTS:

Wednesday, April 28, 2010
3:30 - 4:30
Computer Science Conference Room, Harold Frank Hall Rm. 1132

HOST: Ambuj Singh and Xifeng Yan

SPEAKER: Ullas Nambiar
IBM Research, India

Title: Information Integration, Search and Retrieval

Abstract:

The increasing availability of contextually related heterogeneous
information sources, both over the Web and also within an enterprise
Intranet, has lead to significant interest in query processing frameworks
that can integrate and extract information from such sources. The fact that
such sources are often autonomous and decentralized in nature brings forth
several challenges such as the need to operate with very little information
about the structure, scope, and contents of the information sources and also
the wide variation in the query modeling capabilities of the users. To be
effective, the solution needs to be aware of, and be adaptive to the
characteristics of the sources (contextual correlation, data spread etc) as
well as the users’ inability to capture their informational need using
popular query formulation techniques.

In this talk, I will identify the challenges involved in building
information extraction solutions over sources of information exchange that
are emerging in the Web and the Enterprise. I will describe two systems: 1)
AIMQ: - System for supporting imprecise user queries over structured data
sources and 2) DynaCet: A domain independent dynamic faceted search
solution.

Note: IBM India Research Lab is hiring. Graduating students are welcome to
come by and hand over resumes to Ullas.

Bio:

Dr. Ullas Nambiar is a researcher in the Information Management group at IBM
Research – India, Delhi where he has been involved in designing novel
systems for integrating and analyzing heterogeneous enterprise data sources.
He received a Ph.D in Computer Science from Arizona State University in 2005
and a B.S in Computer Science from M.S.University, Vadodara, India in 1997.
He was a post-doctoral research scholar at UC Davis and a software engineer
at L&T Infotech, India.

He has worked primarily in data integration and search over distributed
sources and of-late has been investigating challenges in dealing with
massive data collections such as those available in the telecom industry. He
has published over 30 papers in leading DB and IR conferences and journals,
and served on several program committees. He has also co-chaired several
international workshops focusing on Web data integration and analysis. More
