Research Area

In 2010 I switched from academia to industry. Since then I have not been active in academic research anymore and this page is not updated anymore. However, you will still be able to find some reference material here in case you are interested.

The focus of my previous research was on topics including

• semantic (web) services
• service discovery and matchmaking languages and frameworks
  (and their functional evaluation and benchmarking)
• automated semantic service composition
• service composition languages and frameworks
  (and their functional evaluation and benchmarking)

Completed Projects

	DIANE - Services in ad hoc Networks In the DIANE project, we aim at developing and evaluating concepts that will allow integrated, efficient and effective usage of services offered in open and dynamic environments like ad-hoc networks. To achieve these goals, we propose mechanisms to address a number of questions: How can service search be facilitated in decentralized, dynamic environments? How can services be described, automatically found, and selected? How can services be efficiently executed? How can fairness be ensured in open environments? We propose mechanisms to describe, find and select services as well as methods including overlays and replication mechanisms to efficiently process such queries. Additionally,… Read More
	OPOSSum OPOSSum (Online POrtal for Semantic Services ) is a portal dedicated to collaboratively build a public test collection of semantic web services. Despite significant research efforts in the field of semantic web services, real tools and applications using them are still rare. One of the main obstacles for improvements in this direction is the lack of sufficiently large and high-quality collections to test and evaluate tools and algorithms for semantic web services. Such collections cannot be built by any single group but only in a collaborative way by the community as a whole. The purpose of OPOSSum is to equip… Read More
