Introduction to the 9th International Workshop on Engineering Service-Oriented Applications (WESOA’13)

The Workshop on Engineering Service Oriented Applications (WESOA’13) focuses on core service software engineering issues keeping pace with new developments such as methods for engineering of cloud services. Over the past nine years the WESOA workshop has been able to attract high-quality contributions across a range of service engineering topics with recent proceedings published by Springer in the LNCS series. The ninth Workshop on Engineering Service Oriented Applications (WESOA’13) was held in Berlin, Germany on 2 December 2013. We have received twenty-four submissions and following review of each paper by at least three reviewers we accepted ten papers for presentation at the workshop and publication in the ICSOC’2013 Workshop Proceedings. The workshop included an excellent keynote presentation by Tom Baeyens, the CEO of Effektif.com titled "A decade of open API’s", followed by ten papers organized into three sessions. The first session focused on Business Processes and I.T. Services Management and includedpapers titled:

From Process Models to Business Process Architectures: Connecting the Layers

by Rami-Habib Eid-Sabbagh and Mathias Weske,

Integrating Service Release Management with Service Solutioning Processes

by Heiko Ludwig, Juan Cappi, Valeria Becker, Bairbre Stewart and Susan Meade, and

Practical Compiler-based User Support during the Development of Business Processes

by Thomas M. Prinz and Wolfram Amme. The second session focused on Automating Process Discovery and Composition and included papers titled:

Towards Automating the Detection of Event Sources

by Nico Herzberg, Oleh Khovalko, Anne Baumgrass, and Mathias Weske,

Discovering Pattern-Based Mediator Services from Communication Logs

by Christian Gierds and Dirk Fahland, and

Goal-driven Composition of Business Process Models

by Benjamin Nagel, Christian Gerth, and Gregor Engels. The final session included papers on Modelling Service-Oriented and Adaptive Systems:

Model Checking GSM-Based Multi-Agent Systems

by Pavel Gonzalez, Andreas Griesmayer, and Alessio Lomuscio,

Towards Modelling and Execution of Collective Adaptive Systems

by Vasilios Andrikopoulos, Antonio Bucchiarone, Santiago Gomez Saez, Dimka Karastoyanova, and Claudio Antares Mezzina,

A Requirements-based Model for Effort Estimation in Service-oriented Systems

by Bertrand Verlaine, Ivan J. Jureta, and Stephane Faulkner, and

Augmenting Complex Problem Solving with Hybrid Compute Units

by Hong-Linh Truong, Hoa Khanh Dam, Aditya Ghose and Schahram Dustdar. The workshop provided an effective platform for exchange of ideas and extensive discussion of topics covered by paper presentations.
