Applying Process Mining to Cross-Organizational Processes

  • Wil van der Aalst — Eindhoven University of Technology, The Netherlands
  • Monday, November 16, 2009


The goal of process mining is to extract information (e.g., process models) from these logs, i.e., process mining describes a family of a posteriori analysis techniques exploiting the information recorded in the event logs. The omnipresence of event logs is an important enabler of process mining. Such information is also present in a cross-organizational setting (e.g., in the form of SOAP messages or EDI messages). Through process mining this information can be used for the discovery of processes, conformance checking, auditing, prediction, diagnostics, and process improvement. See for more information.

Speaker Wil van der Aalst is a full professor of Information Systems at the Technische Universiteit Eindhoven (TU/e) having a position in both the Department of Mathematics and Computer Science and the Department of Technology Management. Currently he is also an adjunct professor at Queensland University of Technology (QUT) working within the BPM group there.

The Relevance of Enterprise Ontology for e-Commerce

  • Jan Dietz — Delft University of Technology, The Netherlands
  • Monday, December 7, 2009


E-Commerce is basically doing commerce while making intensely use of modern Information and Communication Technology (ICT). However, it is important to understand the essence of doing commerce independent of the underlying technology. Enterprise Ontology provides such knowledge. It is defined as an implementation-independent understanding of the construction and the operation of an enterprise. Therefore, the ontological model of an enterprise is the ideal starting point for the design and engineering of the supporting ICT-applications. In this lecture, the notion of Enterprise Ontology will be explained by means of two examples from different e-commerce domains (B2B and B2C).

Speaker Jan L.G. Dietz is emeritus professor at Delft University of Technology, and full professor at Lisbon University of Technology. He holds a Master degree in Electrical Engineering and a Doctoral degree in Computer Science. His current research interests are in Enterprise Architecture, Enterprise Ontology, and Enterprise Governance, the three pillars of Enterprise Engineering. Jan Dietz is the spiritual father of DEMO (Design & Engineering Methodology for Organizations), and honorary chairman of the DEMO Center of Expertise.

Searching Lifelong Learner Metadata Using Query Approximation and Relaxation

  • Alexandra Poulovassilis — University of London, Great Britain
  • Monday, December 14, 2009


Supporting the needs of lifelong learners is leading to research into new learner-centred models of delivering learning resources and opportunities. In this direction, the L4All system aims to support lifelong learners in planning and reflecting on their learning. In this talk, some L4All system's facilities such as finding "people like me" based on string similarity metrics or "what next" for identifying possible future learning options will be described. The second part of the talk will explore more flexible querying techniques, which are based on a combination of query approximation and query relaxation techniques. They would provide users with more flexibility in formulating their requirements and exploring alternative formulations for the timeline search.


Alex Poulovassilis has a BA in Maths from Cambridge Unversity, and an MSc and PhD in Computer Science from Birbeck, London University. Her PhD and postdoctoral research was in data models and languages. She held posts at University College London and King’s College London before returning to Birkbeck as Reader in 1999 and Professor of Computer Science from 2001.

Innovative Methods for Service Engineering and Management

  • Rudi Studer — University of Karlsruhe, Germany
  • Monday, January 18, 2010


Services constitute the predominant sector of our economy. However, they were neglected by research for a long time. The Service Science, Management and Engineering (SSME) initiative aims at establishing service science as a multidisciplinary research area. Besides giving a general overview of SSME, this talk is about concrete challenges that arise when companies deploy service-oriented architectures and applications. One of them is to formally describe services in order to support discovery of the right service for a given task. In most cases, not only descriptions of functionality and quality aspects, but also of the terms and conditions of a service are significant. This includes usage policies of the input data, the output data, and the service itself. Usage policies restrict actions on services and data and impose obligations on actions.


Rudi Studer is Full Professor in Applied Informatics at the University of Karlsruhe, Institute AIFB. In addition, he is director of the Karlsruhe Service Research Institute (KSRI). His research interests include knowledge management, Semantic Web technologies and applications, ontology management, data and text mining, service-oriented architectures, Service Science, and Semantic Grid. Rudi Studer is also director in the research department Information Process Engineering at the FZI Research Center for Information Technologies at the University of Karlsruhe and member of the executive board of the FZI Research Center as well as co-founder of the spin-off company ontoprise GmbH that develops semantic applications. He is engaged in various national and international cooperation projects, among others the DFG Graduate School Information Management and Market Engineering (IME), the EU Integrated Project NeOn (as Technical Director), and the THESEUS research program funded by the Federal Ministry of Economics and Technology (BMWi). He is one of the vice presidents of the Semantic Technology Institute International (STI2).

Computational Persuasive Systems for Small Groups in a Museum

  • Oliviero Stock — ITC-Irst, Italy
  • Monday, January 25, 2010


In this talk I will present some persuasive systems we are developing and take a specific aim: can technology help orienting natural face-to-face communication to a cultural discussion? A museum visit can be considered successful if a conversation about the cultural experience develops. We foresee a stop at the museum café to be the ideal situation to introduce a tabletop interface meant to foster the conversation of the visitors. In a second situation, a dramatic computer-based presentation genre has been devised specifically for influencing and assessing mobile small group conversation.


Oliviero Stock, Irst senior fellow, has been at ITC-irst since 1988 and has been its Director from 1997 to 2001. His activity is mainly in artificial intelligence, natural language processing, intelligent interfaces, cognitive technologies. He is the author of nearly two hundred peer-reviewed papers and author or editor of twelve volumes, and member of the editorial board of a dozen scientific journals. He has also been an invited speaker at over sixty conferences; participant or coordinator at over twenty panels.
