********************************************************************

The Sixth International Workshop on Querying Graph Structured Data 
(GraphQ 2017)
http://www.isgroup.unimo.it/graphq2017
March 21, 2017 - Venice, Italy 

Co-located with the EDBT/ICDT 2017 Joint Conference
http://edbticdt2017.unive.it
March 21-24, 2017 - Venice, Italy 
*******************************************************************

* Call for participation *

We are very glad to announce that the GraphQ 2017 workshop will feature an invited
talk by Angela Bonifati, Full Professor in Computer Science at Lyon 1 University
(France). Her keynote will explore graph queries at 360 degrees and will be the
concluding event of an exciting program. The two technical sessions will focus on various
aspects concerning graph query models, graph query processing and system performance
evaluation.


Join us and enjoy the workshop!

    - Graph Queries: Generation, Evaluation and Learning
      (Angela Bonifati)
      
      Abstract: Several modern graph query languages are capable of expressing sophisticated
      graph queries, which return nodes connected by arbitrarily complex paths. Such paths
      can be synthesized by regular expressions and often involve recursion. Such graph
      queries are known as Regular Path Queries and correspond to Property Paths in
      Sparql 1.1. Recently, with my colleagues I have been investigating regular path
      queries and their combinations by looking at the generation problem, the complexity
      of query evaluation and the learning problem. In this talk, I will begin with a
      brief recap of graph queries and their expressive power. I will then provide an
      overview of a comprehensive query-oriented graph benchmark that we have designed
      and assessed. I will next discuss the theoretical results of our study on the
      complexity of regular simple path queries. I will then present a learning framework
      for regular path queries and discuss its potential along with its practical
      feasibility. To conclude, I will briefly outline our ongoing work and pinpoint
      lingering issues and research directions in the study of graph queries.

17:45 Closing
