Interlinking Data and Knowledge in Society, Research and Enterprises with Linked Data

Prof. Sören Auer Prof. Sören Auer  / Dr. Christoph Lange
University of Bonn, GERMANY

Date: 9 June 2014

The Linked Data paradigm has emerged as a powerful enabler for data and knowledge interlinking and exchange using standardized Web technologies. In this talk we will discuss research challenges of Linked Data management regarding extraction, linking, curation, enrichment, quality analysis and visualization. We will also showcase some examples of successful Linked Data deployments benefiting society, research and enterprises and give an outlook on further promising application areas.

Challenges of Efficient Management of Big Complex Data

Prof. Bela StanticProf. Bela Stantic
Griffith University, AUSTRALIA

Date: 10 June 2014

New information systems contain different forms of complex data such as structured data from transactions we make, unstructured data as text communications of different kinds, variety of multimedia files and also video streams. To add the complexity, data can be and often is temporal in nature. This data is collected from numerous sources including company databases, different sensor, public profiles on social networking sites, etc. This big data can yield extremely useful information, however, it poses the challenge in its management due to the diversity of data, the speed at which it is delivered and used, and also due to the volume it is creating. To make effective use of big data access method is required, which will be able to efficiently access data not only from own domain but also from other domains user is authorized to access. This talk will address the problem of efficient management of big data and several concepts will be elaborated.

About speaker:
Assoc. Professor Bela Stantic is member of Institute for Integrated and Intelligent Systems within the Griffith University, Gold Coast, Australia. His area of research is efficient management of complex data structures. He has published more than 80 conferences and journals. He was/is served on the Program Committees of more than 100 conferences and was/is doing the editorial duties of many Journals in area of his research.

From Requirements to Specifications in Service-Oriented Systems Engineering

Dr. Audrone Lupeikiene
Vilnius University, LITHUANIA

Date: 11 June 2014

Dr. Audrone LupeikieneAbstract:
Service orientation nowadays is not just a set of technologies; it is a system development paradigm - a way of developing and deploying software as well as whole enterprise systems. The paradigm related issues include the following:

- A broad group of different stakeholders are involved in the development, maintenance and service consuming. This group becomes more heterogeneous if the services offered by external providers are used. The stakeholders have different, often conflicting viewpoints expressed in their service requirements.
- A perspective defines a subset of service characteristics, which are observed from one‘s viewpoint. A service comprises both business and software system aspects. To describe, specify, and evaluate a service from some perspective the separation of concerns between business service itself and underlying software system should be done.
- On the one hand, there are business goals outlining the business level requirements. On the other hand, service-orientation impacts the system quality characteristics. So, a decision on required system characteristics should be made at this boundary.

There is therefore a need for a conceptual framework and methods to describe, relate to each other, and negotiate the different viewpoints and perspectives on a service, to balance the stakeholders' requirements and to flow-down these business level requirements to a software level specification. The talk also includes comments on current service-oriented requirements engineering processes, highlights existing problems, and open issues.

About speaker:
Audrone Lupeikiene is the associate professor, senior researcher at the Institute of Mathematics and Informatics, Vilnius University. She is the author of more than 40 papers on software and information systems engineering topics, the co-editor of two books and author of textbook on theoretical and technological aspects of Information Systems. She is currently involved in two research projects (Theoretical and Engineering Aspects of e-Service Technology Development and Application in High-Performance Computing Platforms, and Production Effectiveness Navigator). She has participated in Program Committees of many conferences and workshops, is a member of editorial board of Scientific Journal of Riga Technical University, Computer Sciences. Her research interests include information system engineering, service-oriented architecture, and software engineering.
