We aim at helding WETICE 2022 in presence; however, due to the COVID-19 pandemic, WETICE could be held in mixed mode or online. TBA TBA Over its 19 years in existence, ACEC has focused on projects that leverage the adaptability, autonomy and intelligence of first-class software agents for the collaboration that occurs across enterprise software systems. In 2022, the organizers would like to continue to explore research in agent-based computing, but also we will welcome a wider array of projects that leverage adaptive techniques that may not include all the attributes of first class software agents. In addition to our traditional domain areas, i.e. Computer Supported Collaborative Work, Workflow and Supply Chain Management, Automation in Virtual Enterprises, and Automated Distributed Service Composition, we are also interested in new adaptive techniques such as collaboration when organizations leverage emerging web techniques such as Cloud Computing, Crowd-Sourcing and general Social Networking.
In addition to traditional papers, the forthcoming 19th episode of ACEC welcomes papers from two focus areas:

• Adaptive and Agent-based Services
• Adaptive Techniques for Organizational/Enterprise Use of Emerging Web Paradigms (Cloud, Crowd-sourcing, Mobile Apps)

These two themes represent important areas where software agents can leverage their distributed nature along with their proactive and autonomous characteristics to provide solutions for complex problems which are difficult to address using traditional/existing technologies.

With the popularity and pervasiveness of services in the emerging digital world, enterprises must carefully evaluate how to make their services openly accessible. Furthermore, it is important for enterprises to learn how to exploit the services of others at the consumer level (crowd-sourcing) while taking into account the unexpected circumstances and changing scenarios, which frequently occur in organizational ecosystems.

In both of these (above given) contexts, software agents and adaptive software techniques can play an important role. In this respect, ACEC 2021 intends to bring together researchers and practitioners to discuss the key issues, approaches, open problems, innovative applications, and trends in this research area. We enthusiastically solicit papers that address agent mediation and management of services and/or products of on-line businesses.

Topics of interests include but are not limited to:

• Adaptive and/or agent-mediated workflow, supply chain, or virtual enterprises
• Methodologies, languages and tools to support agent collaboration
• Agent architectures and infrastructures for dynamic collaboration
• Adaptive and/or Agent-based service architectures and infrastructures
• Service Oriented Architecture (SOA) based on agents
• Services for dynamic agent collaboration
• Agent-to-Human service interactions
• Autonomous, Adaptive and/or Agent-mediated service integration
• Organizational and enterprise systems that leverage Web 2.0
• Adaptive and Agent-mediated cloud environments
