"Engineering the Web for users, developers and the crowd"
Toulouse, France | July 1-4 2014 - http://icwe2014.webengineering.org/
(call for research papers, industrial papers and late breaking results)
ICWE 2014 AT A GLANCE
ICWE aims to bring together researchers and practitioners from various disciplines in academia and industry to tackle the emerging challenges in the engineering of Web applications and in the problems of its associated technologies, as well as the impact of those technologies on society and culture. The 14th edition of ICWE is centered around the theme of “Engineering the Web for users, developers and the crowd”, hereby highlighting the importance of all the different people that, somehow, participate in the development process of interactive Web applications and, ultimately, becomes the actors and the main users of the best practices and results of the research performed in the domain of the Web Engineering. ICWE 2014 is innovating with the introduction of six major research tracks: cross-media and mobile applications, HCI and the Web, modelling and engineering web applications, quality aspects of Web applications, social web applications, and Web applications composition and mashups. In addition to the six research tracks, ICWE 2014 also welcomes contributions as demos and posters, student papers to the PhD Symposium, tutorials and workshops, which will be subject of individual calls for papers. The conference will be held at Toulouse, France Toulouse which is the 3rd university city of France and it hosts one of the oldest in Europe (founded in 1229).

ICWE 2014 RESEARCH TRACKS (further details at http://icwe2014.webengineering.org/main-tracks/)
* Cross-media and mobile Web applications
The modern Web use is nomadic and across various devices - often simultaneously - and the Web experience should be enjoyable, of high quality and consistent across all devices, regardless of the purpose, place and time of use. Such mobile, cross-device usage forces Web developers to evolve or re-invent their engineering methods and techniques to these new requirements and user demands. Web applications have to be tailored to deal with the constraints imposed by mobile technology such as small screens, low (and sometimes expensive) bandwidth, limited browser capabilities, different usage situations, cross- and multi-device use. Simultaneously, modern mobile devices offer a rich set of sensors, available through current Web browsers, allowing Web pages access to geo-location, NFC, and other sensor data, as well as tracking user identity across devices. Also, he rise of the app as an alternative for Web sites is a concern to be addressed to ensure a future, open Web.
* HCI and the Web
Most Web applications are conceived as interactive systems that aim at communicating with users. Users do not only consume information via the Web, but can also play an active role by contributing content (e.g., Web 2.0), get involved in the development process of Web applications (e.g., agile and user-centered design processes) and even conceive their own components by interacting with specialized tools (e.g., end-user development tools). In this context, there are many user roles involved in the socio-technical environment encompassing the development of Web applications. This track is devoted to the studies on user interface software and technologies that improve the relationship between users and Web applications. We welcome research focused on improving usability, accessibility, and user experience with Web applications, as well as user-centered design approaches that describe how Web technology and innovative design solutions can help users to better accomplish their tasks over the Web.
* Modeling and Engineering Web applications
The Modeling and Engineering Web applications track concerns principles, methods, notations, processes, approaches, and tools for supporting the development and evolution of high-quality Web applications in a more effective and efficient way. Model-driven approaches are of particular interest for addressing complexity, scalability, and maintainability of solutions for the development of Web applications, improving communication among participants of the development teams, and supporting the development of innovative tools and process. Furthermore, empirical and comparative studies of applying Web engineering methods and approaches, especially model-driven ones, are of particular interest.
* Quality aspects of Web applications
The development and usage of Web applications in different platforms and devices are continuously increasing. Web applications have become the most predominant form of software delivery today, with users and businesses choosing to rent or use software rather than buy it. The success of such applications depends on their capability to satisfy the customer needs. This has led to increased attention on quality models, processes and methods that facilitate understanding, evaluating, and especially improving the overall quality of products, processes and quality in use.
* Social Web applications
Social aspects are an integral part of todays Web, and the widespread use of the Web to connect, share and tap into collective knowledge provides a wealth of actionable data. The crowd can be deployed in various ways, i.e. the so-called crowdsourcing and human computation applications, and their generated data is valuable for developers, researchers and marketers alike. Successfully tapping into the crowds knowledge, and gathering, analyzing, and visualizing complex, heterogeneous social data, and putting it to good use are major current challenges.
* Web applications composition and mashups
Composition on the Web aims to integrate Web services, Web data sources and Web widgets into other Web services or Web applications. Mashups, and especially mashup tools with their modeling languages and instruments for mashup development, bring significant innovation as they tackle integration across the data, API and user interface layers; they aim at simplicity and ease of use rather than completeness of features and full expressiveness (compared to traditional Web programming languages and tools), but still they allow fairly sophisticated development tasks in a Web browser. Hereby, mashups represent an important and emerging strain of Web applications, with their own set of research challenges and opportunities.

Anna Hannemann from the ACIS group at RWTH Aachen University gave a presentation on "Community Dynamics in Open Source Software Projects: Aging and Social Reshaping" at the Open Source Systems Conference in Slovenia. This presentation is part of our research on community analytics which makes heavy use of social network analysis.
Wednesday, 17 July 2013
Tomorrow, our colleagues from the TU Dresden will visit the ACIS group at RWTH Aachen University. Daniel Schuster will give a computer science colloquium talk at the computer science department of RWTH Aachen University. He will talk about "XMPP - The Potential Heartbeat of Global-Scale Pervasive Computing". Details can be found here.
Since the TU Dresden group and the ACIS group are both working on similar topics, we expect a lively discussion and future collaboration.
Abstract: The original vision of Pervasive Computing as an experience "refreshing as a walk in the woods" has been quite over-stressed in the last years. Nowadays we already live in a world of personal device zoos (notebooks, pads, phones and even smart watches), immersive social interaction and more and more addressable things connected to this overall experience. But while each of the demoed use cases looks impressive by itself, there is yet no means of global-scale communication and coordination to connect these isolated islands comparable to HTTP in connection with HTML and other standards for the Web. We explain how the eXtensible Messaging and Presence Protocol XMPP is about to fill this gap and what is still missing. After a crash course in relevant XMPP basics we show current research and standardization work in XMPP for pervasive computing, social computing and the Internet of Things. We furthermore present research work within the Mobilis project at TU Dresden which adds session mobility and service-oriented XMPP development to these building blocks.

Michael Derntl from my ACIS group (Advanced Community Information Systems) gave a presentation on "An Embeddable Dashboard for Widget-Based Visual Analytics on Scientific Communities" at the I-KNOW 2012 in Graz, Austria. The presentation reports results from the ongoing TELMAP project. But it is also a contribution to the discussion on learning or research dashboards. At least it reports on some already finished research.
Michael Derntl, Stephan Erdtmann, Ralf Klamma: An Embeddable Dashboard for Widget-Based Visual Analytics on Scientific Communities, in Proceedings of 12th International Conference on Knowledge Management and Knowledge Technologies, I-KNOW '12. ACM Press (2012)
The web hosts massive amounts of data about scientific communities, for instance in bibliographic databases, research project databases, and more recently on the social web. These data sets provide key information on the activities and artifacts relevant to the community. Due to the scattered nature and sheer size of Web 2.0 data sets it is currently difficult for stakeholders to comprehensively and to smoothlessly monitor key indicators hidden in that data. To address this issue, we developed an embeddable, personalizable dashboard, which can be populated with widgets that visualize the results of arbitrary queries over relational databases in real time. As a pilot case the dashboard was deployed at LearningFrontiers.eu, a service and support portal for the European Technology-Enhanced Learning community, to provide access to pre-configured visualizations of queries over their data sources. Community stakeholders evaluated the dashboard and generally responded positively in regard to its usability and usefulness. From a technical perspective the main advantage of the proposed dashboard infrastructure is the simple and seamless integration with a community's existing data sources and web portals.
The work in this paper is based on earlier work by Dominik Renzel from my ACIS group on widget-based dashboards. I gave a presentation last year on this topic. The work was done mostly in the context of the ROLE EU project. A SDK has been developed to support developer.

Call for Papers
6th Intl. Conf. on Communities and Technologies (C&T 2013)
Munich, Germany, June 29 - July 2, 2013
Communities and Technologies (C&T 2013), hosted from 29th June – 2nd July
2013 in Munich. This biennial meeting serves as a forum for stimulating and
disseminating research on the complex connections between communities – both
physical and virtual – and information and communication technologies.
C&T 2013 welcomes participation of researchers, designers, educators, and
students from the many disciplines and perspectives bearing on the
interaction between community and technology.
The conference program includes competitively selected, peer-reviewed
papers, as well as workshops, panels, posters, a doctoral consortium, and
invited speakers.
People
• Conference Co-Chairs: Michael Koch & Johann Schlichter
• Paper Chairs: Wolfgang Prinz & Christine Satchell
• Workshop Chairs: Alessandra Agostini & Tom Gross
• Doctoral Consortium Chair: Geraldine Fitzpatrick
• Student Volunteer Chairs: Alexander Richter & Wolfgang Woerndl
Conference Themes
C&T focuses on the notion of communities as social entities comprised of
people who share something in common; this common element may be geography,
needs, interests, practices, organizations, or other bases for social
connection. Communities are considered to be a basic unit of social
experience. Information and communication technologies (ICTs) can interact
with communities in many complex ways, For example, ICTs can support
community formation and development by facilitating communication and
coordination among members. Conversely, the lack of attention to the
surrounding community context may inhibit the design and effective use of
ICT innovations thus eroding the potential for new technologies to enhance
everyday life.
Topics appropriate for submission to this conference are manifold. Examples
of some of the vibrant areas of communities and technology research include,
but are not limited to:
• (Virtual) community formation and development
• Technical support for communities
• Communities and innovation
• Urban informatics
• Social capital, communities, and technology
• Interactions between online and offline communities
• Augmenting interactions between physically co-located groups

Khaled Ahmed Nagi Rashed, Dominik Renzel, Ralf Klamma and Matthias Jarke: Community and trust-aware fake media detection, MULTIMEDIA TOOLS AND APPLICATIONS, 2012, DOI: 10.1007/s11042-012-1103-3
Abstract
Nowadays, it becomes increasingly difficult to find reliable multimedia content in the Web 2.0. Open decentralized networks (on the Web) are populated with lots of unauthenticated agents providing fake multimedia. Conventional automatic detection and authentication approaches lack scalability and the ability to capture media semantics by means of forgery. Using them in online scenarios is computationally expensive. Thus, our aim was to develop a trust-aware community approach to facilitate fake media detection. In this paper, we present our approach and highlight four important outcomes. First, a Media Quality Profile (MQP) is proposed for multimedia evaluation and semantic classification with one substantial part on estimating media authenticity based on trust-aware community ratings. Second, we employ the concept of serious gaming in our collaborative fake media detection approach overcoming the cold-start problem and providing sufficient data powering our Media Quality Profile. Third, we identify the notion of confidence, trust, distrust and their dynamics as necessary refinements of existing trust models. Finally, we improve the precision of trust-aware aggregated media authenticity ratings by introducing a trust inference algorithm for yet unknown sources uploading and rating media.
Today, the online first version of our journal paper Building mobile multimedia services: a hybrid cloud computing approach appeared.
Dejan Kovachev, Yiwei Cao and Ralf Klamma: Building mobile multimedia services: a hybrid cloud computing approach, MULTIMEDIA TOOLS AND APPLICATIONS, 2012, DOI: 10.1007/s11042-012-1100-6
Abstract
Mobile multimedia services are in high demand, but their development comes at high costs. The emergent computing paradigm cloud computing has great potential to embrace these issues. In fact, we are at the early stage of the coalescence of cloud computing, mobile multimedia and the Web. Motivated by the tremendous success story of the Web based on its simplicity principles, we argue for a comprehensive review on current practices of web and mobile multimedia cloud computing techniques for avoiding frictions. We draw on experience from the development of advanced collaborative multimedia web applications utilizing multimedia metadata standards like MPEG-7 and real-time communication protocols like XMPP. We propose our i5CLoud, a hybrid cloud architecture, which serves as a substrate for scalable and fast time-to-market mobile multimedia services. This paper demonstrates the applicability of emerging cloud computing concepts for mobile multimedia.More information about our work on cloud computing is available at the i5cloud Website at our chair at RWTH Aachen.
