NCBO Webinar: Yolanda Gil, June 20 - Semantic Workflows and Provenance-Aware Software

The next NCBO Webinar will be presented by Yolanda Gil from USC/ISI on
"Semantic Workflows and Provenance-Aware Software" at 10:00am PDT,
Wednesday, June 20.  Below is information on how to join the online meeting
via WebEx and accompanying teleconference. For the full schedule of the
NCBO Webinar presentations see: http://www.bioontology.org/webinar-series.


ABSTRACT:
I will describe our current research on intelligent workflow systems that
provide assistance and automation for complex data analysis processes.
Semantic workflows extended workflow representations with semantic
constraints that express characteristics of data and analytic models.  We
have developed algorithms to propagate these semantic constraints
throughout the workflow structure, select executable components for
underspecified steps, and suggest parameter values.  These algorithms allow
us to assist users to create valid workflows, and to automate workflow
generation given high-level user guidance.  Semantic workflows enable us to
publish more than provenance, by sharing workflows with abstract steps that
reflect the overall data analysis method rather than just publishing
execution traces.

I will also talk about the importance of provenance-aware software that
both uses and generates metadata as the data is being processed.  I will
illustrate our work on combining a workflow system and a data integration
system when they both are provenance-aware, and how new capabilities are
enabled when provenance is brought to the forefront in the design of
software systems for science.


SPEAKER BIO:
Dr. Yolanda Gil is Director of Knowledge Technologies and Associate
Division Director at the Information Sciences Institute of the University
of Southern California, and Research Professor in the Computer Science
Department. She received her M.S. and Ph. D. degrees in Computer Science
from Carnegie Mellon University.  Her research interests include
intelligent user interfaces, knowledge-rich problem solving, and the
semantic web. An area of recent interest is collaborative large-scale data
analysis through semantic workflows.  She recently led the W3C Provenance
Group that charted a community standardization effort in this area.  Dr.
Gil has served in the Advisory Committee of the Computer Science and
Engineering Directorate of the National Science Foundation. She is Chair of
ACM SIGART, the Association for Computing Machinery's Special Interest
Group on Artificial Intelligence.  She was elected Fellow of the American
Association of Artificial Intelligence (AAAI) in 2012.
