VLDB Workshop on Semantic Data Management (SemData@VLDB)

The goal of the SemData workshop is to provide a platform for the discussion and investigation of various aspects related to semantic databases and data management in the large. Many of the semantic data management challenges cumulate in the need for scalable and performing database solutions for semantic data, a building block that runs largely behind comparable non-semantic technologies. In order to make semantic technologies take on the targeted market share, it is indispensable that technological progress allows semantic repositories to reach near performance parity with some of the best RDBMS solutions without having to omit the advantages of a higher query expressivity compared to basic key-value stores, or the higher schema flexibility compared to the relational model. It is time that one must no longer pay a heavy price in terms of longer run times or more expensive equipment for profiting from the flexibility of the generic physical model underlying the semantic graph-based structures of RDF. We also recognize that there will always be a burden with more flexibility. Hence, the goal is to minimize the drawbacks and maximize the advantages of the semantic RDF-minded repositories.

3rd Future Internet Symposium 2010 (FIS 2010)

The Future Internet Symposium (FIS 2010) is now in its third year and will once again offer a forum for researchers and practitioners to discuss key issues in the Future Internet: networks, services, multimedia, Internet of Things, security and trust. This year we will offer a particular focus on the aspect of virtualisation of ICT resources and services.

INSEMTIVES ISWC2010 Tutorial - 10 Ways to make your Semantic App. addictive (Tutorial@ISWC2010)

Useful semantic content cannot be created fully automatically, but motivating people to become an active part of this endeavor is still an art more than a science. In this tutorial we will revisit fundamental design issues of semantic-content authoring technology in order to find out which incentives speak to people to become engaged with the Semantic Web, and to determine the ways they can be transferred into technology design.

We will present a combination of methods from areas as diverse as community support, participation management, usability engineering, and incentives theory, which can be applied to analyze semantically enabled systems and applications and design incentivized variants thereof, as well as empirically grounded best practices which should be taken into account in order to encourage large-scale user participation. We will demonstrate the utility of these methods in three case studies in the areas of enterprise knowledge management, media and entertainment, and IT ecosystems. Hiding the technicalities of knowledge engineering, semantic annotation and data integration behind captivating, entertaining games is one prominent instance of incentivized semantic content authoring technology.

Our tutorial will introduce a game design API together with a number of guidelines for realizing casual games which produce useful semantic content, and present several games based thereupon that have been developed in the European research project INSEMTIVES.

4th Workshop on Non-Functional Properties and SLA Management in Service-Oriented Computing @ECOWS'10

Non-functional properties play an important role in all service related tasks, especially in discovery, selection and substitution of services. It is simple to imagine a scenario in which multiple services which provide the same functionality can fulfill a user request. In this case the ability of the user to differentiate between the services depends upon their non-functional properties. Modeling, managing and performing service related tasks such as discovery, composition, negotiation and agreement based on NFPs become fundamental challenges in Service-Oriented Architectures especially in real business settings. Directly connected to the tasks mentioned above are the specification, enforcement and management of Service Level Agreements (SLAs). SLAs give the service consumer some level of guarantee that the provider and the service/s that they provide will operate within acceptable bounds - particularly with regards to non-functional properties and QoS values. At the same time SLAs serve a role for the provider in planning resource allocation and avoiding unexpected legal wrangles. With the ever-growing demand for eBusiness, service providers are increasingly interested in enforcing contracts electronically allowing autonomous supervision of service status and management. Machine-understandable NFPs and QoS models are therefore key to the widespread uptake of SLAs as well as all of the service related tasks mentioned above.

The workshop aims to tackle the research problems around methods, concepts, models, languages and technology that enable management of non-functional properties and Service Level Agreements in the context of Service Oriented Computing. This proposed workshop aims to bring together researchers and industry attendees addressing these issues, to promote and foster a greater understanding of how the management of NFP, QoS and SLAs can assist business to business and enterprise application integration.
