Invited talks for TCGOV 2007
Karlsruhe University, Germany
Dr. Andreas Abecker manages together with Prof. Dr. Rudi Studer the "Knowledge Management and Semantic Technologies" team within FZI, Karlsruhe University's technology transfer organization for information and communication technologies. He has about ten years experience in technology transfer, application-oriented research and R&D management in areas such as Expert Systems in technical domains, Data, Text, and Web Usage Mining, and Business-process Oriented and Agent-Based Knowledge Management.
In his lab, about 20 Ph.D. students, software enginers and postdocs, currently work on topics such as ontology-based information integration and interoperability, social software and Web2.0, knowledge management (KM) in software engineering, semantic middleware (web services, grid systems), etc.
The team ran (and is still running) a series of three subsequent European research projects about semantics and KM in eGovernment (the OntoGov, FIT and SAKE projects). In his talk, Dr. Abecker will give an overview of the potential benefits of semantic technologies in eGovernment.
Career in local administration since 1990, Dr. iuris (Salzburg 1994), Master Européen en Médiation (CH Sion 2002); from 2001 onward director of local administration (town hall) in Voecklabruck - an Austrian town of 13.000 inhabitants; an organization employing 220 persons and facing 37 political representatives headed by the mayor; highly interested in state of the art ICT technologies, regularly attending conferences on related topics, contributing to the development of E-Government on several levels, whenever possible; firmly believing in Europe and the possibility to resolve problems peacefully on all levels.
John Domingue: Semantic Web Services and Business Processes: Approaches and Applications
In this talk I will describe two related EU Integrated Projects: DIP and SUPER. DIP was a three year project, which finished at the end of 2006, involving 20 partners which addressed the topic of applying Semantic Web technology to support the development of business applications through the reuse of Web Services. The main results of DIP comprised the Web Services Modelling Ontology (WSMO) and a reference architecture for semantic execution environments which is currently being standardised through OASIS. In the talk I will illustrate the DIP approach through one of our use cases in eGovernment. Within this use case we developed a system which supports emergency planners at Essex County Council by combining the DIP platform with the Google Maps API.
SUPER is a three year project involving 19 partners which started in Spring 2006. The aim of SUPER is to combine Semantic Web Services and Business Process Modelling to enable business experts to directly manage enterprise processes which reside in ICT systems without recourse to IT staff. During the talk I will outline the SUPER approach which is based upon a 4-layer framework underpinned by a stack of ontologies.

Alois Ferscha: Digital Artefacts
Pervasive Computing has postulated to invisibly integrate technology into everyday objects in such a way, that these objects turn into smart things. Not only a single object of this kind is supposed to represent the interface among the "physical world of atoms" and the "digital world of bits", but a whole landscapes of them. As an approach to link each artefact in the physical world with the software objects in the digital world we propose stick-on solutions - Digital Artefacts - as the symbiosis of technology rich artefacts and a P2P based coor-dination framework.
A spatial proximity based spontaneous interaction approach for "shared nothing" P2P systems has been developed and imple-mented in our P2P coordination framework. Mobile peers, once in spatial proximity to each other, coordinate their activities based on the exchange and analysis of self descriptions in metadata format. Each peer individually conducts a similarity analysis of the role and profile data received from other peers in vicinity, and invokes triggers if a certain similarity threshold is reached.
I will present aspects of the underlying profile description language expressing peer preferences with respect to the particular context in which the interaction is attempted (like time, geoposition, owner, environmental conditions, etc.), the mathematical formulation of similarity metrics and the matching analysis of semistructured data, the mechanisms for consensus finding and coordination in peer ensembles, and the component model within which the framework is implemented. Findings will be demonstrated in scenarios involving our "Digital Artefact" miniaturized hardware platform, serving as a stick-on solution for artefacts.
Wei-Ying Ma: Building Infrastructure for Web-scale Data Mining
To accelerate Web innovation, we found it necessary to build an infrastructure to provide large-scale data processing and data management capabilities.
In this talk, I will introduce WebStudio, an infrastructure we have constructed to facilitate the development and experimentation with new data mining algorithms for improving Web search. Some new search technologies developed from this infrastructure will be also demonstrated.
Wasim Sadiq: Have BPMS delivered for Processes like DBMS have for Data?
Business process management systems (BPMS) have been around for more than a decade. Their promise has been to separate the process logic from applications and to manage it at a separate software layer just like database management systems (DBMS) have been used to manage data. Today, there is hardly any enterprise application that does not depend on DBMS technology. However, even after many years of research, development, standardization and major product offerings, BPMS have not lived up to their promise and potential. In this talk, I will highlight some of the strengths of BPMS that in fact are also hindering their wide spread utilization in enterprise applications. I will also discuss some potential ideas to overcome these shortcomings.
A Min Tjoa: Security Issues for the Use of Semantic Web in e-Commerce
The goal of the presentation is to describe innovative methods to secure future Semantic Web based e-Commerce approaches. Therefore new security concepts and methods, capable of handling semantics, have to be developed.
The following main areas need special security considerations in a semantic environment:
Security ontology / Security within ontologies: Ontologies require a dual security approach. On one hand, a specific security ontology will constitute an own security domain. This will help to integrate security concepts properly in the early stages of the architecture. This way, security will not be simply added as an afterthought. This often happens in similar architecture development, usually leaving critical weaknesses in the systems which are difficult to overcome. The integrated Error sub-ontology is used to classify system errors regarding to their security exposure.
On the other hand, security within ontologies is an interesting topic. It might be necessary to restrict the access to the ontology itself - depending on the real world application - or it might be useful to enforce special types of access control restraints represented in the ontology. In most cases ontologies are used to store important and confidential data and so it is necessary to protect the ontology against unauthorized access.
Trust Issues regarding communicating parties will be presented. In some scenarios, such as in environments where sensitive data may be handled, establishing valid trust relationships during the negotiation phase will be a crucial aspect. Representing the confidentiality requirements of the CIA triad (i.e. confidentiality, integrity and availability), the trust issues must be treated with special attention, especially if the frameworks' agents are supposed to negotiate and exchange data automatically or semi-automatically.
