John Mylopoulos has made ground-breaking contributions to three areas of computer science: arti?cial intelligence, information systems and software - gineering. His contributions have been celebrated on multiple occasions. First, Misha Missiko? organized a one-day symposium on conceptual modeling on June 17, 2003, inVelden, Austria, tocelebrateJohn's60thbirthday.Second, JohnTsotsos led the organization of a day of celebrations on June 27th, 2009 in Toronto, Canada, on the occasionof John's retirementfrom the Departmentof Computer Science of the University of Toronto. This book grew out of our desire to honor and thank John by presenting him at the Toronto reunion with a volume that re?ects his belief that conceptual modeling is becoming a fundamental skill that will be a necessary tool for all futurecomputerscientists.Thepapersinthis bookarewrittenbyleading?gures in technical areas that intersect with conceptual modeling, as well as by John's closest collaborators.We are pleased to present this collection of papers that we believe are of lasting signi?cance and could also be used to support a course on conceptual modeling. We are extremely grateful to the eminent authors, who have contributed such high-quality material.

This book presents a coherent, well-balanced survey of recent advances in software engineering approaches to the design and analysis of realistic large-scale multi-agent systems (MAS). The chapters included are devoted to various techniques and methods used to cope with the complexity of real-world MAS. Reflecting the importance of agent properties in today's software systems, the power of agent-based software engineering is illustrated using examples that are representative of successful applications.

Information systems have become the backbone of all kinds of organizations - day. In almost every sector - manufacturing, education, health care, government and businesses large and small - information systems are relied upon for - eryday work, communication, information gathering and decision-making. Yet, the in?exibilities in current technologies and methods have also resulted in poor performance, incompatibilities and obstacles to change. As many organizations are reinventing themselves to meet the challenges of global competition and e-commerce, there is increasing pressure to develop and deploy new technologies that are ?exible, robust and responsive to rapid and unexpected change. Agent concepts hold great promise for responding to the new realities of - formation systems. They o?er higher-level abstractions and mechanisms which address issues such as knowledge representation and reasoning, communication, coordination, cooperation among heterogeneous and autonomous parties, p- ception, commitments, goals, beliefs, intentions, etc., all of which need conc- tual modelling. On the one hand, the concrete implementation of these concepts can lead to advanced functionalities, e.g., in inference-based query answering, transaction control, adaptive work ?ows, brokering and integration of disparate information sources, and automated communication processes. On the other hand, their rich representational capabilities allow for more faithful and ?- ible treatments of complex organizational processes, leading to more e?ective requirements analysis and architectural/detailed design.

The explosive growth of application areas such as electronic commerce, ent- prise resource planning and mobile computing has profoundly and irreversibly changed our views on software systems. Nowadays, software is to be based on open architectures that continuously change and evolve to accommodate new components and meet new requirements. Software must also operate on di?- ent platforms, without recompilation, and with minimal assumptions about its operating environment and its users. Furthermore, software must be robust and ] autonomous, capable of serving a naive user with a minimum of overhead and interference.

Thisproceedingsvolumeofthe5thAOISWorkshopisanopportunityforlooking back at ?ve years of organizing AOIS workshops. What did we achieve with the AOIS workshop series? Where were we ?ve years ago, where are we now? Did ourthemeimpactontheinformationsystems?eldinthewaythatwehadhoped for? AOIS workshops have taken place in Seattle, Heidelberg, Stockholm, Austin, Montr eal, Interlaken, Toronto, Bologna, Melbourne, and Chicago, always in c- junction with a major conference on either multiagent systems in arti?cial - telligence (AI/MAS) or information systems (IS). We have tried to innovate in holding these workshops as biconference events (each year AOIS held two wo- shop events, one at an AI/MAS conference and one at an IS conference), as well as using the AOIS web site as a medium for communication among researchers. So, certainly, we have reached a wide audience of researchers around the world from both the AI/MAS and IS communities. But did we also manage to build up a dedicated AOIS community? Five years ago, we wrote: "Agent concepts could fundamentally alter the nature of information systems of the future, and how we build them, much like structured analysis, ER modeling, and Object-Orientation has precipitated fundamental changes in IS practice. " Of course, a period of ?ve years is too short for evaluating the success or failure of a new scienti?c paradigm. But still we may observe that while most IS conferences meanwhile list agents as one of their many preferred topics, agent-orientation is generally not considered to be a fundamental IS paradigm.

The explosive growth of application areas such as electronic commerce, ent- prise resource planning and mobile computing has profoundly and irreversibly changed our views on software systems. Nowadays, software is to be based on open architectures that continuously change and evolve to accommodate new components and meet new requirements. Software must also operate on di- rent platforms, without recompilation, and with minimal assumptions about its operating environment and its users. Furthermore, software must be robust and autonomous, capable of serving a naive user with a minimum of overhead and interference. Agent concepts hold great promise for responding to the new realities of so- ware systems. They o?er higher-level abstractions and mechanisms that address issues such as knowledge representation and reasoning, communication, coor- nation, cooperation among heterogeneous and autonomous parties, perception, commitments, goals, beliefs, and intentions, all of which need conceptual mo- ling. On the one hand, the concrete implementation of these concepts can lead to advanced functionalities, e.g., in inference-based query answering, transaction control, adaptive work?ows, brokering and integration of disparate information sources, and automated communication processes.

Cooperative Information Systems have emerged as a central concept in a variety of applications, projects, and systems in the new era of e-business. The conference at which the papers in this volume were presented was the ninth international conference on the topic of Cooperative Information Systems (CoopIS 2001), and was held in Trento, Italy on September 5-7, 2001. Like the previous conferences, CoopIS 2001 has been remarkably successful in bringing together representatives of many di?erent ?elds, spanning the entire range of e?ective web-based Cooperative Information Systems, and with interests ranging from industrial experience to original research concepts and results. The 29 papers collected here out of the 79 ones that were submitted, dem- strate well the range of results achieved in several areas such as agent te- nologies, models and architectures, web systems, information integration, m- dleware technologies, federated and multi-database systems. The papers th- selves, however, do not convey the lively excitement of the conference itself, and the continuing spirit of cooperation and communication across disciplines that has been the hallmark of these conferences. We would especially like to thank our keynote speakers: Philip A. Bernstein (Microsoft Research, USA), Edward E. Cobb (BEA Systems, USA), and Ma- izio Lenzerini (Universit'a di Roma "La Sapienza", Italy) for providing a portrait of the best contemporary work in the ?eld. We would also like to thank the many people who made CoopIS 2001 possible.

This book constitutes the refereed proceedings of the 31st International Conference on Advanced Information Systems Engineering, CAiSE 2019, held in Rome, Italy, in June 2019. The 41 full papers presented in this volume were carefully reviewed and selected from 206 submissions. The book also contains one invited talk in full paper length. The papers were organized in topical sections named: information system engineering; requirements and modeling; data modeling and analysis; business process modeling and engineering; information system security; and learning and mining in information systems. Abstracts on the CAiSE 2019 tutorials can be found in the back matter of the volume.

Privacy is a burden for most organizations, the more complex and wider an organization is, the harder to manage and enforce privacy is.GDPR and other regulations on privacy impose strict constraints that must be coherently enforced, considering also privacy needs of organization and their users. Furthermore, organizations should allow their users to express their privacy needs easily, even when the process that manages users' data is complex and involves multiple organizations. Many research work consider the problem using simplistic examples, with solutions proposed that never actually touch pragmatic problems of real, large organizations, with thousands of users and terabytes of personal and sensitive data. This book faces the privacy management problem targeting actual large organizations, such as public administrations, including stakeholders in the process of definition of the solution and evaluating the results with its actual integration in four large organizations. The contribution of this book is twofold: a privacy platform that can be customized and used to manage privacy in large organizations; and the process for the design of such a platform, from a state-of-the-art survey on privacy regulations, through the definition of its requirements, its design and its architecture, until the evaluation of the platform.

The Future Internet envisions a move toward widespread use of services as a way of networked interaction. However, while the technologies for developing and deploying services are well established, methods for ensuring trust and security are fewer and less mature. Lack of trust and confidence in composed services and in their constituent parts is reckoned to be one of the significant factors limiting widespread uptake of service-oriented computing. This state-of-the-art survey illustrates the results of the Aniketos - Secure and Trustworthy Composite Services - project (funded under the EU 7th Research Framework Programme). The papers included in the book describe the solutions developed during the 4-year project to establish and maintain trustworthiness and secure behavior in a constantly changing service environment. They provide service developers and providers with a secure service development framework that includes methods, tools, and security services supporting the design-time creation and run-time composition of secure dynamic services, where both the services and the threats are evolving. The 16 chapters are organized in the following thematic sections: state of the art of secure and trustworthy composite services; the Aniketos platform; design-time support framework; run-time support framework; and case studies and evaluation.

A novel, model-driven approach to security requirements engineering that focuses on socio-technical systems rather than merely technical systems. Security requirements engineering is especially challenging because designers must consider not just the software under design but also interactions among people, organizations, hardware, and software. Taking this broader perspective means designing a secure socio-technical system rather than a merely technical system. This book presents a novel, model-driven approach to designing secure socio-technical systems. It introduces the Socio-Technical Modeling Language (STS-ML) and presents a freely available software tool, STS-Tool, that supports this design approach through graphical modeling, automated reasoning capabilities to verify the models constructed, and the automatic derivation of security requirements documents. After an introduction to security requirements engineering and an overview of computer and information security, the book presents the STS-ML modeling language, introducing the modeling concepts used, explaining how to use STS-ML within the STS method for security requirements, and providing guidelines for the creation of models. The book then puts the STS approach into practice, introducing the STS-Tool and presenting two case studies from industry: an online collaborative platform and an e-Government system. Finally, the book considers other methods that can be used in conjunction with the STS method or that constitute an alternative to it. The book is suitable for course use or as a reference for practitioners. Exercises, review questions, and problems appear at the end of each chapter.
