Title      : Querying Web Applications Under Terms of Uncertainty
Abstract   :
Many businesses offer their services to customers via Web-based application
interfaces.  Reasoning  about  execution  flows  of  such applications  is
extremely  valuable  for  companies:  it  can  be used to optimize business
processes,  employ  targeted  advertisements, reduce operational costs, and
ultimately  increase  competitiveness.
Such reasoning often operates in an environment   inducing  partial
information  and  uncertainty  of  various flavors.  This is because
executions  often  depend  on unknown external parameters, such as  users
behavior, interaction with other applications, servers response time,  etc.
In  this talk I will consider (1) models for capturing Web applications,
their  executions and queries over these;  (2)  query  evaluation algorithms
over applications/execution  traces  under  these  models, and  (3)
practical implementations, e.g. for  recommending navigation flows within
Web Applications.
Short Bio:
Daniel Deutch is a senior lecturer in the Computer Science Department of Ben
Gurion University. He received his PhD in Computer Science from Tel Aviv
University in 2010 and was a Postdoc at the University of Pennsylvania
(UPenn) and at the INRIA research institute. He has received a number of
awards for his research including the Israeli Ministry of Science Eshkol
grant and ICDT best student paper award.
Daniel has been a member of the Program Committee of leading international
conferences (e.g. WWW,PODS,ICDT,EDBT) and a reviewer for leading journals
(e.g. VLDBJ, ACM TODS, TKDE). His research is funded by grants from the
US-Israel Binational Science Foundation and the Israeli Ministry of Science.
