Service-Oriented Computing exploits services as the fundamental elements of computer-based systems. It has been applied to various areas and promotes fundamental changes to the way software systems are being analyzed, architected, designed, implemented, tested, evaluated, delivered, consumed, maintained and evolved. Consequently, a new paradigm of software and system engineering discipline, i.e. Service-Oriented Engineering, has emerged and advanced rapidly in the past decade. Among many remarkable milestones in the development of this new paradigm are the wide adoption of the Microservices architectural style supported by Docker and other container-based virtualisation techniques in the design of cloud native application in the industry, and the DevOps movement in the organisation of development process supported by automated tools for continuous testing, continuous integration and continuous delivery. Recent advances in service oriented computing, in particular Internet-of-Things, Industry 4.0, Edge and Fog computing, mobile and cloud computing combined with Big Data analytics, robotics, blockchain and decentralised ledger applications, and application of artificial intelligence and deep learning techniques, etc., have provided exciting opportunities to make significant progress in understanding and solving complex real-world challenges. Such challenges typically require a system-level approach that models a complex system at different levels of abstraction, helps to develop sound architectures for addressing separate system requirements and concerns, and integrates diverse sources of knowledge on the system’s components and their interactions. Therefore, the revolution of the software and system engineering paradigm brought by service-orientation is still unfolding, with each new technology development bringing new challenges and opportunities.

Starting from 2005, SOSE is a pioneering IEEE sponsored international conference devoted to the research in engineering service-oriented systems. It covers all aspects of service-oriented engineering from architectures, techniques, tools and languages to methodologies. Continuing the tradition of the last twelve editions of SOSE Symposia, the 15th SOSE intends to provide a forum for researchers and practitioners to exchange latest observations, insights, achievements and visions in Service-Oriented System Engineering. SOSE 2021 invites original submissions in all the areas of the system engineering and software engineering methods, techniques, tools, applications, and experiments for software services.

Submission Guidelines
All papers need to be submitted electronically using the EasyChair conference system in PDF format. The materials presented in the papers should not be published or submitted for publication elsewhere. Each paper is limited to 10 pages (4 pages for WIP and 6 pages for PhD Symposium) including figures and references using IEEE Computer Society Proceedings Manuscripts style (two columns, single-spaced, 10pt font). You can find the IEEE Computer Society Proceedings Author Guidelines at the following web page: https://www.ieee.org/conferences_events/conferences/publishing/templates.html.

All submission will be reviewed by members of the conference program committee considering the criteria of novelty, significance of the contribution, technical soundness, maturity of the work, and presentation quality. The WIP and PhD Symposium track will apply criteria that consider the special nature of the papers in those tracks. Once accepted, at least one author is required to register for the conference and present the paper at the conference in person. The paper will be included into the IEEE conference proceedings published by IEEE Computer Society Press (indexed by EI) and included in IEEE Computer Society Digital Library.

Survey And Emerging Subjects Tutorial Papers
In addition to regular research paper and industry practice/case study papers, SOSE 2021 will also invite some tutorial papers, which review the state-of-the-art of the research on services engineering as well as the related emerging paradigms and technologies. These papers should summarize the recent research advance in service engineering from different perspectives, identify the open issues and future trends and challenges in the field. SOSE 2021 also encourages vision papers which discuss future and emerging issues, including emerging paradigms, technologies and applications. Papers should be no more than 10 pages in length.

The title in the submission for review should be prefaced with “WIP” to aid reviewers.

PhD Symposium
A PhD symposium track will accept submissions authored primarily by PhD students and the first author will need to be a registered PhD student. This track accepts papers in areas as listed above and allows submission of papers of up to 6 page length. Preface the title with "PhD” in submissions.
