Provenance-based System Accountability


Ponente: Luc Moreau (University of Southampton)

Lugar: Seminario Mirian Andrés (Edificio CCT)

Hora: martes 9 de mayo, 13:00

Resumen: Provenance is a record that describes the people, institutions, entities, and activities, involved in producing, influencing, or delivering a piece of data or a thing in the world.  Provenance is regarded as essential to describe the source of data and whether data can be trusted. Provenance has recently been identified by USACM as one of principles to support transparency and accountability.

Some 10 years after beginning research on the topic of provenance, I  co-chaired the provenance working group at the World Wide Web Consortium. The working group published the PROV standard for provenance in 2013.

In this talk, I will present some use cases for provenance, the PROV standard and some flagship examples of adoption.  I will then move on to our current research area aiming to exploit provenance, in the context of the Sociam, SmartSociety, ORCHID projects. Doing so, I will present techniques to deal with large scale provenance, to build predictive models based on provenance, and to analyse provenance.

The slides of the talk are available from the following link.

Biografía: Luc Moreau is a Professor of Computer Science and Head of the Web and Internet Science group (WAIS), in the department Electronics and Computer Science (ECS) at the University of Southampton. Luc was co-chair of the W3C Provenance Working Group, which resulted in four W3C Recommendations and nine W3C Notes, specifying PROV, a conceptual data model for provenance the Web, and its serializations in various Web languages. Previously, he initiated the successful Provenance Challenge series, which saw the involvement of over 20 institutions investigating provenance inter-operability in 3 successive challenges, and which resulted in the specification of the community Open Provenance Model (OPM).
