This book constitutes the refereed proceedings of the 19th International Working Conference on Requirements Engineering: Foundation for Software Quality, REFSQ 2013, held in Essen, Germany, in April 2013. The papers are organized in 8 topical sections on requirements engineering and architecture; natural language requirements; requirements engineering and quality; traceability; requirements engineering and business/goals; requirements engineering and software development; requirements engineering in practice; product lines and product management.

We would like to welcome you to the proceedings of the workshops held in c- junction with the 27th International Conference on Conceptual Modeling (ER 2008). While the ER main conference covers a wide spectrum of conceptual modeling research, increasingly complex real-world problems demand new p- spectives and activeresearchin new applications.The ER workshopsattempt to provideresearchers, students, andindustry professionalswitha forumto present and discuss emerging hot topics related to conceptual modeling. We received 13 excellent proposals for workshops to be held with ER 2008. We accepted the following seven based on peer reviews: 1. The Second International Workshop on Conceptual Modeling for Life S- ences Applications (CMLSA 2008), organized by Yi-Ping Phoebe Chen and Sven Hartmann. 2. The 5th International Workshopon Evolution and Change in Data Mana- ment (ECDM 2008), organized by Fabio Grandi. 3. The 4th International Workshop on Foundations and Practices of UML (FP-UML 2008), organized by Juan Trujillo and Andreas L. Opdahl. 4. The First International Workshop on Modeling Mobile Applications and Services (M2AS 2008), organized by Fernando Ferri, Patrizia Grifoni, and Maria Chiara Caschera. 5. The Second International Workshop on Requirements, Intentions and Goals in Conceptual Modeling (RIGiM 2008), organized by Colette Rolland, C- son Woo, and Camille Salinesi. 6. The Second International Workshop on Semantic and Conceptual Issues in Geographic Information Systems (SeCoGIS 2008), organized by Esteban Zim anyi and Christophe Claramunt. 7. The 5th International Workshop on Web Information Systems Modeling (WISM 2008), organized by Flavius Frasincar, Geert-Jan Houben, and Philippe Thiran."

This book constitutes the refereed proceedings of the 19th International Conference on Advanced Information Systems Engineering, CAiSE 2007, held in Trondheim, Norway in June 2007.

The 39 revised full papers presented together with 1 keynote talk were carefully reviewed and selected from 301 submissions. The papers are organized in topical sections on ontologies, extended enterprises, information integration, service-oriented architecture, strategic alignment, requirements, process modeling, method engineering, novel applications, participative modeling, and process-aware information systems.

This book constitutes the proceedings of the 17th International Conference on Research Challenges in Information Sciences, RCIS 2023, which took place in Corfu, Greece, during May 23–26, 2023. It focused on the special theme "Information Science and the Connected World".The scope of RCIS is summarized by the thematic areas of information systems and their engineering; user-oriented approaches; data and information management; business process management; domain-specific information systems engineering; data science; information infrastructures, and reflective research and practice. The 28 full papers presented in this volume were carefully reviewed and selected from a total of 87 submissions. The book also includes 15 Forum papers and 6 Doctoral Consortium papers. The contributions were organized in topical sections named: Requirements; conceptual modeling and ontologies; machine learning and analytics; conceptual modeling and semantic networks; business process design and computing in the continuum; requirements and evaluation; monitoring and recommending; business process analysis and improvement; user interface and experience; forum papers; doctoral consortium papers. Two-page abstracts of the tutorials can be found in the back matter of the volume.

This book constitutes the refereed proceedings of the 34th International Conference on Conceptual Modeling, ER 2015, held in Stockholm, Sweden, in October 2015. The 26 full and 19 short papers presented were carefully reviewed and selected from 131 submissions. The papers are organized in topical sections on business process and goal models, ontology-based models and ontology patterns, constraints, normalization, interoperability and integration, collaborative modeling, variability and uncertainty modeling, modeling and visualization of user generated content, schema discovery and evolution, process and text mining, domain-based modeling, data models and semantics, and applications of conceptual modeling.

This volume constitutes the proceedings of the 4th IFIP WG 8.1 Working Conference on the Practice of Enterprise Modeling, held in Oslo, Norway, during November 2-3, 2011. The conference series is a dedicated forum where the use of enterprise modeling (EM) in practice is addressed by bringing together researchers, users, and practitioners in order to develop a better understanding of the practice of EM, to contribute to improved industrial EM applications, and to share knowledge and experiences. The 18 papers presented were carefully reviewed and selected from 38 submissions. Authored by both researchers and practitioners, they reflect the fact that EM encompasses human, organizational issues as well as technical aspects related to the development of information systems. The papers are organized in five thematic sessions on process modeling, business modeling, enterprise architecture, EM, and model-driven development. In addition, two keynotes on EM in an agile world and on intra- and inter-organizational process mining complete the volume.
