Our increasingly smart environments will sense, track and model users and provide them with personalized services. We can already embed computers in everyday objects such as shirt buttons and pencils; objects of all sizes, from wristwatches to billboards, will soon incorporate high-quality flexible displays; we have improved access to wireless Internet communication; and we are now transitioning from traditional linear to targeted interactive media. The convergence of these factors -- miniaturization, display technologies, wireless communication, and interactive media -- will allow us to leave our desktop computers and move to a radical computing paradigm, the ubiquitous display environment, where media and visual content will support a rich variety of display devices that enable users to interact with information artifacts in a seamless manner. This is one of the most exciting and important areas of technology development and this book addresses the challenge within the context of an educational and cultural experience. This is inherently a multidisciplinary field and the contributions span the related research aspects, including system architecture and communications issues, and intelligent user interface aspects such as aesthetics and privacy. On the scientific side, the authors integrate artificial intelligence, user modeling, temporal and spatial reasoning, intelligent user interfaces, and user-centric design methodologies in their work, while on the technological side they integrate mobile and wireless networking infrastructures, interfaces, group displays, and context-driven adaptive presentations. This book is of value to researchers and practitioners working on all aspects of ubiquitous display environments, and we hope it leads to innovations in human education, cultural heritage appreciation, and scientific development.

This book constitutes selected papers from the lectures given at the workshops held in conjunction with the User Modeling, Adaptation and Personalization Conference, UMAP 2011, Girona, Spain, in July 2011. The 40 papers presented were carefully reviewed and selected for inclusion in this book. For each workshop there is an overview paper summarizing the workshop themes, the accepted contributions and the future research trends. In addition the volume presents a selection of the best poster papers of UMAP 2011. The workshops included are: AST, adaptive support for team collaboration; AUM, augmenting user models with real worlds experiences to enhance personalization and adaptation; DEMRA, decision making and recommendation acceptance issues in recommender systems; PALE, personalization approaches in learning environments; SASWeb, semantic adaptive social web; TRUM, trust, reputation and user modeling; UMADR, user modeling and adaptation for daily routines: providing assistance to people with special and specific needs; UMMS, user models for motivational systems: the affective and the rational routes to persuasion.

Ubiquitous user modeling differs from generic user modeling by three additional concepts: ongoing modeling, ongoing sharing, and ongoing exploitation. Systems that share their user models will improve the coverage, the level of detail, and the reliability of the integrated user models and thus allow better functions of adaptation. Ubiquitous user modeling implies new challenges of interchangeability, scalability, scrutability, and privacy.

This volume presents results of a series of workshops on the topic of Ubiquitous User Modeling since 2003 and additional workshops at various other conferences e.g. on User Modeling and Adaptive Hypermedia in the last four years.

The 8 revised full papers presented were carefully reviewed and selected from the best lectures given at the workshops and were significantly extended to be included in the book.

Information technology is a rapidly changing field in which researchers and devel- ers must continuously set their vision on the next generation of technologies and the systems that they enable. The Next Generation Information Technologies and Systems (NGITS) series of conferences provides a forum for presenting and discussing the latest advances in information technology. NGITS conferences are international events held in Israel; previous conferences have taken place in 1993, 1995, 1997, 1999, 2002, and 2006. In addition to 14 reviewed papers, the conference featured two keynote lectures and an invited talk by notable experts. The selected papers may be classified roughly in five broad areas: * Middleware and Integration * Modeling * Healthcare/Biomedical * Service and Information Management * Applications NGITS 2009 also included a demonstration session and an industrial track focusing on how to make software development more efficient by cutting expenses with techn- ogy and infrastructures. This event is the culmination of efforts by many talented and dedicated individuals.

This book constitutes the refereed proceedings of the 6th International Workshop on Next Generation Information Technologies and Systems, NGITS 2006, held in Kibbutz Shefayim, Israel, July 2006. The book presents 28 revised full papers and four revised short papers together with three invited papers. Topical sections include information integration, next generation applications, information systems development, security and privacy, semi-structured data, frameworks, models and taxonomies, simulation and incremental computing, and more.

This book constitutes the thoroughly refereed proceedings of the 22nd International Conference on User Modeling, Adaption and Personalization, held in Aalborg, Denmark, in July 2014. The 23 long and 19 short papers of the research paper track were carefully reviewed and selected from 146 submissions. The papers cover the following topics: large scale personalization, adaptation and recommendation; Personalization for individuals, groups and populations; modeling individuals, groups and communities; Web dynamics and personalization; adaptive web-based systems; context awareness; social recommendations; user experience; user awareness and control; Affective aspects; UMAP underpinning by psychology models; privacy; perceived security and trust; behavior change and persuasion.
