Quality of Experience: From User Perception to Instrumental Metrics (Dagstuhl Seminar 12181)

Authors: Markus Fiedler, Sebastian Möller, and Peter Reichl


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12181 "Quality of Experience: From User Perception to Instrumental Metrics". As follow-up of the Dagstuhl Seminar 09192 "From Quality of Service to Quality of Experience", it focused on the further development of an agreed definition of the term Quality of Experience (QoE) in collaboration with the COST Action IC1003 "Qualinet", as well as inventories of possibilities to measure QoE (beyond the usual user polls) and to exploit feedback between users and systems that reflects QoE issues. The report furthermore describes the mode of work throughout the seminar, with focus on personal statements by the participants, results of the group works, and open challenges.

Social, Supply-Chain, Administrative, Business, Commerce, Political networks: a multi-discipline perspective (Dagstuhl Perspectives Workshop 12182)

Authors: Mattias Häsel, Thorsten Quandt, and Gottfried Vossen


Abstract
The information society is shaped by an increasing presence of networks in various manifestations, most notably computer networks, supply-chain networks, and social networks. Online networks nowadays connect people all around the world at day and night, and allow to communicate and to work collaboratively and efficiently. What has been a commodity in the private as well as in the enterprise sectors independently for quite some time now is currently growing together an increasing pace. As a consequence, the time has come for the relevant sciences, including computer science, information systems, social sciences, economics, communication sciences, and others, to give up their traditional "silo-style" thinking and enter into borderless dialogue and interaction. The purpose of this Perspectives Workshop has been to play an enabling role in this future dialogue, to review where we stand today, and to outline directions in which we urgently need to move, in terms of both research and teaching, but also in terms of funding. This report summarizes the discussions of the workshop and their findings.

Artificial and Computational Intelligence in Games (Dagstuhl Seminar 12191)

Authors: Simon M. Lucas, Michael Mateas, Mike Preuss, Pieter Spronck, and Julian Togelius


Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12191 "Artificial and Computational Intelligence in Games". The aim for the seminar was to bring together creative experts in an intensive meeting with the common goals of gaining a deeper understanding of various aspects of artificial and computational intelligence in games, to help identify the main challenges in game AI research and the most promising venues to deal with them. This was accomplished mainly by means of workgroups on 14 different topics (ranging from search, learning, and modeling to architectures, narratives, and evaluation), and plenary discussions on the results of the workgroups. This report presents the conclusions that each of the workgroups reached. We also added short descriptions of the few talks that were unrelated to any of the workgroups.

Co-Design of Systems and Applications for Exascale (Dagstuhl Perspectives Worksop 12212)

Authors: Arndt Bode, Adolfy Hoisie, Dieter Kranzlmüller, and Wolfgang E. Nagel


Abstract
With more and more machines achieving petascale capabilities, the focus is shifting towards the next big barrier, exascale computing and its possibilities and challenges. There is a common agreement that using machines on this level will definitively require co-design of systems and applications, and corresponding actions on different levels of software, hardware, and the infrastructure. Defining the vision of exascale computing for the community as providing capabilities on levels of performance at extreme scales, and identifying the role and mission of the involved experts from computer science has laid the basis for further discussions. By reflecting on the current state of petascale machines and technologies and identifying known bottlenecks and pitfalls looming ahead, this workshop derived the concrete barriers on the road towards exascale and presented some ideas on how to overcome them, as well as raising open issues to be addressed in future leading-edge research on this topic.

Cognitive Approaches for the Semantic Web (Dagstuhl Seminar 12221)

Authors: Dedre Gentner, Frank van Harmelen, Pascal Hitzler, Krzysztof Janowicz, and Kai-Uwe Kühnberger


Abstract
A major focus in the design of Semantic Web ontology languages used to be on finding a suitable balance between the expressivity of the language and the tractability of reasoning services defined over this language. This focus mirrors the original vision of a Web composed of machine readable and understandable data. Similarly to the classical Web a few years ago, the attention is recently shifting towards a user-centric vision of the Semantic Web. Essentially, the information stored on the Web is from and for humans. This new focus is not only reflected in the fast growing Linked Data Web but also in the increasing influence of research from cognitive science, human computer interaction, and machine-learning. Cognitive aspects emerge as an essential ingredient for future work on knowledge acquisition, representation, reasoning, and interactions on the Semantic Web. Visual interfaces have to support semantic-based retrieval and at the same time hide the complexity of the underlying reasoning machinery from the user. Analogical and similarity-based reasoning should assist users in browsing and navigating through the rapidly increasing amount of information. Instead of pre-defined conceptualizations of the world, the selection and conceptualization of relevant information has to be tailored to the user's context on-the-fly. This involves work on ontology modularization and context-awareness, but also approaches from ecological psychology such as affordance theory which also plays an increasing role in robotics and AI. During the Dagstuhl Seminar 12221 we discussed the most promising ways to move forward on the vision of bringing findings from cognitive science to the Semantic Web, and to create synergies between the different areas of research. While the seminar focused on the use of cognitive engineering for a user-centric Semantic Web, it also discussed the reverse direction, i.e., how can the Semantic Web work on knowledge representation and reasoning feed back to the cognitive science community.
