Seminar: Advanced Topics in Services Computing

Hauptseminar an der Universitaet des Saarlandes, FR 6.2 Informatik, LVst 94717


This seminar is concerned with advanced topics in services computing, in particular the discovery and automated composition of web services. There are thousands of web services for a huge variety of applications and described in different formats. Web service descriptions in XML-based WSDL, WADL, or REST APIs do not provide any formal service semantics. From the strong AI perspective, that makes it hard for intelligent applications to understand, discover, and compose heterogeneous services. On the other hand, in the semantic web, service semantics are described with formal ontology-based service description languages like OWL-S, WSML, and SA-WSDL. For both, web services and semantic web services, there are quite sophisticated methods, techniques, and tools for their discovery and composition available. In this seminar, we will take a closer look at some of them, and discuss their strength and weaknesses in theory and practice.

The seminar type is classic in the sense that registered participants will present and discuss assigned topics. All certificates for successful participation in the seminar will be marked. The seminar counts 7 ECTS credit points.


This seminar aims primarily at advanced master students in computer science who preferably hold a B.Sc. degree in this or related field. Solid knowledge in Artificial Intelligence, semantic web, and web services is required. References to surveys of relevant fields of the seminar are given on the topic page and expected to be read by registered participants in due course of their preparation for the seminar. Attendance of the seminar without registration (no presentation and certificate) by anyone who is interested in the topics is, of course, very much welcome but subject to available space. The seminar language is English.
