Interoperability and Semantics - a reoccurring Issue?
Prof. Erich J. Neuhold
Research Group Multimedia Information Systems
University of Vienna
Währinger Straße 29, 1090 Vienna, Austria
Interoperability is a qualitative property of computing infrastructures that denotes the ability of the sending and receiving systems to exchange and properly interpret information objects across system boundaries.
Since this property is not given by default, the interoperability problem and the representation of semantics have been an active research topic for approximately four decades. Early database models such as the Relational Model used schemas to express semantics and implicitly aimed at achieving interoperability by providing programming independence of data storage and access.
After a number of intermediate steps such as Object Oriented Data Bases and Semi - Structured Data such as hypertext and XML document models, the notions of semantics and interoperability became what they have been over the last ten years in the context of the World Wide Web and more recently the concept of Open Linked Data.
With this talk we investigate semantics and interoperability research from the point of view of information systems. It should give an overview of existing old and new interoperability techniques and point out future research directions, especially for concepts found in Open Linked Data and the Semantic WEB.

New Technologies: We have seen nothing yet
Prof. Hermann Maurer
Institut für Informationssysteme und Computer Medien
Graz University of Technology
Inffeldgasse 16c, 8010 Graz, Austria
In this talk we will argue that developments in science will continue with increasing speed, opening completely new vistas. Why this is so is not just due to the usual trivial observations such as "developments are happening very fast and it seems even at accelerating speed". Rather, we will show a number of much deeper reasons, why nw developments will come at us as surprise, and to an extent hard to imagine. Some of the arguments are surprising in themselves and shed a light on how we think, and how we have to change our thinking to at least grasp a bit of what is going to happen. Surprisingly, it also turns out that some reasons show the weaknesses of our information age and how knowing this, we can become better in handling complicated situations and negotiations. If this sounds all a bit vague, it is, and it is vague on purpose: the speaker wants to surprise everyone in the audience a few times by presenting concrete samples and does not want to give away some of the highlights in this abstract.

Ameliorating Music Recommendation
Dr. Markus Schedl
Department of Computational Perception
Johannes Kepler University Linz
Altenberger Strasse 69, 4040 Linz, Austria
Successful music recommendation systems need to incorporate information on at least three levels: the music content, the music context, and the user context. The former refers to features derived from the audio signal; the second refers to aspects of the music or artist not encoded in the audio, nevertheless important to human music perception; the third refers to contextual aspects of the user which change dynamically.
In this keynote, we briefly review the well-researched categories of music content and music context features, before focusing on user-centric models, which have been neglected for a long time in retrieval and recommendation approaches. In particular, we address the following tasks: (i) geospatial music recommendation from microblog data, (ii) user-aware music playlist generation on smart phones, and (iii) matching places of interest and music.
The approaches presented for task (i) rely on large-scale data inferred from microblogs, motivated by the fact that social media represent an unprecedented source of information about every topic of our daily lives. Information about music items and artists is thus found in abundance in user-generated data. The questions of how to infer information relevant to music recommendation from microblogs and what to learn from them are discussed. So are different ways of incorporating this kind of information into state-of-the-art music recommendation algorithms.
The presented approaches targeted at tasks (ii) and (iii) model the user in a more comprehensive way than just using information about her location and music listening. We report results of a user study aiming at investigating the relationship between music listening activity and a large set of contextual user features. Based on these, an intelligent mobile music player that automatically adapts the current playlist to the user context is presented.
Eventually, we discuss different methods to solve task (iii), i.e., to determine music that suits a given place of interest, for instance, a major monument. In particular, we look into knowledge-based and tag-based methods to match music and places.

Mobile Mobility: The Road User Information Systems of the Future
Dr.-Ing. Stefan Schulte
Distributed Systems Group
Vienna University of Technology
Argentinierstrasse 8/184-1, 1040 Wien, Austria
Within the last years, the availability of mobile Internet connections has been increased significantly. Nevertheless, the impact of this ubiquitous Web access has not arrived at road user information systems with a few exceptions for navigation systems or traffic monitoring. Even those services that are available today are very limited, as they mainly use GPS or TMC information combined with Web-based maps. Making full use of the Internet availability can enable a whole range of new services and apps for road users, helping them to make their journey safer, more comfortable, and more environmental friendly.
In this talk, we will identify current research gaps in road user information systems, namely the need to overcome heterogeneous and missing interoperability of relevant data sources, a missing end-to-end integration of data and functionality, and the demand for a homogeneous, unified user interface to road user information systems. Eventually, we will present some results from the ongoing EU FP7 project SIMPLI-CITY - The Road User Information System of the Future, which contributes to solve these issues.
Dr.-Ing. Stefan Schulte is a Postdoctoral Researcher at the Distributed Systems Group at Vienna University of Technology and the project manager of the ongoing EU FP7 project SIMPLI-CITY - The Road User Information System of the Future (http://www.simpli-city.eu). Before joining TU Vienna, Stefan headed the research group "Service-oriented Computing" at the Multimedia Communications Lab at Technische Universität Darmstadt, Germany, as well as the SOA Competence Center at Hessisches Telemedia Technologie Kompetenz-Center (httc e.V.), Darmstadt.
Stefan's research strives to bring us closer to the efficient ad hoc utilization of distributed computing resources through the Internet. In recent years, two major trends in distributed systems have been the subject of large interest both in the software industry and IT research. First, organizations' demand for IT-based support for cross-organizational collaboration has led to the wide adoption of the paradigm of Service-oriented Architectures (SOA). Related to that, the standardization of Web service technologies has led to the emergence of the (yet to be fulfilled) "Internet of Services", i.e., a global SOA. Second, the need for agile and flexible IT systems has led to the rise of Cloud Computing as the dominating paradigm for provisioning computing resources in a scalable, on-demand fashion.
His research interests span the areas of SOA and Cloud Computing, with a special focus on Quality of Service (QoS) and Quality of Experience (QoE) aspects. He is working on concepts and implementations that help to bridge the heterogeneity arising from different communication protocols and technologies.
