This book constitutes the refereed proceedings of the 16th International Semantic Web Conference, ESWC 2019, held in Portorož, Slovenia.The 39 revised full papers presented were carefully reviewed and selected from 134 submissions. The papers are organized in three tracks: research track, resources track, and in-use track and deal with the following topical areas: distribution and decentralisation, velocity on the Web, research of research, ontologies and reasoning, linked data, natural language processing and information retrieval, semantic data management and data infrastructures, social and human aspects of the Semantic Web, and, machine learning.

This book constitutes the proceedings of the 20th International Semantic Web Conference, ISWC 2021, which took place in October 2021. Due to COVID-19 pandemic the conference was held virtually.The papers included in this volume deal with the latest advances in fundamental research, innovative technology, and applications of the Semantic Web, linked data, knowledge graphs, and knowledge processing on the Web.  Papers are organized in a research track, resources and in-use track. The research track details theoretical, analytical and empirical aspects of the Semantic Web and its intersection with other disciplines. The resources track promotes the sharing of resources which support, enable or utilize semantic web research, including datasets, ontologies, software, and benchmarks. And finally, the in-use-track is dedicated to novel and significant research contributions addressing theoretical, analytical and empirical aspects of the Semantic Web and its intersection with other disciplines.

This book constitutes the revised selected papers of the combined workshops on Web Information Systems Engineering, WISE 2014, held in Thessaloniki, Greece, in October 2014. The 19 selected papers presented were carefully revised and report from the four workshops: computational social networks, IWCSN 2014, enterprise social networks, Org2 2014, personalization and context-awareness in cloud and service computing, PCS 2014, and data quality and trust in big data, QUAT 2014.

Six parallel Business Process Management workshops were held on September 5th, 2005, in conjunction with the Third International Conference on Business Process Management (BPM 2005) in Nancy, France. This was the first time BPM had asso- ated workshops, and the workshop program was a great success. The topics of the workshops ranged from fundamental process modeling primitives to the recently emerged field of Web service choreography and orchestration, rep- sented in the “Workshop on Business Processes and Services” and the “Workshop on Web Service Choreography and Orchestration;” a topic which intersects the research fields of business process management and Web services. Another strong focus was on business process design and business process intelligence, emerging areas that have gained increasing importance in supporting business process reengineering to derive superior process designs. These topics were covered in the respective wo- shops. A widely discussed topic in several sessions was business process interoperability in the workshop on “Enterprise and Networked Enterprises Interoperability.” Finally, the last workshop in these proceedings called “Business Process Reference Models” aimed at discussing different views on reference models in order to come to a c- mon understanding of the terms involved. We would like to thank the workshop organizers for their efforts in the workshop preparation, the organization of the review process, the exciting workshop programs and their management onsite and for their cooperation in the post-publication process.

This book constitutes the revised selected papers of the combined workshops on Web Information Systems Engineering, WISE 2011 and WISE 2012, held in Sydney, Australia, in October 2011 and in Paphos, Cyprus, in November 2012. The seven workshops of WISE 2011-2012 have reported the recent developments and advances in the contemporary topics in the related fields of: Advanced Reasoning Technology for e-Science (ART 2012), Cloud-Enabled Business Process Management (CeBPM 2012), Engineering in the Semantic Enterprise (ESE 2012), Social Web Analysis for Trend Detection (SoWeTrend 2012), Big Data and Cloud (BDC 2012), Personalization in Cloud and Service Computing (PC-S 2011), and User-Focused Service Engineering, Consumption and Aggregation (USECA 2011).
