The 10th International Cross-Disciplinary Conference on Web Accessibility

W4A 2013 (use #w4a13)              

Co-Located with the 21th International World Wide Web Conference, WWW2013
13-15th May 2013 - Rio de Janeiro, Brazil


Theme: Bring Your Own Device!

Topics and Content

The WHO defines disability as "a complex phenomenon, reflecting an
interaction between features of a person's body and features of the
society in which he or she lives". Web Accessibility should address
this interaction aspect of "disability" so that a wide range of
problems are tackled.  While the need for and usage of assistive
technologies may raise barriers that hinder the perception, the
understanding, and the operation of the Web, other barriers may be
caused by technological and situational impairments; think, for
example, of people with low vision that use a tablet rather than an
interactive board or a desktop.

Depending on the device used, the range of barriers being faced may
vary.  One could use assistive technologies to enhance the
capabilities of a PC, a tablet or a smartphone; but one could also
rely on desktop browsers on very large screens, interactive TVs, Web
kiosks, gaming consoles, Web browsers in cars or gym equipment,
interactive boards, tangible and natural user interfaces, or more
esoteric devices. Due to particular interaction modalities, access to
information or interactive services may be hindered or even prevented;
due to the quantity and richness of information and services, ability
to process information may be reduced; due to infrastructure (e.g.,
cellular networks in under-developed lands), certain services may
become unusable; due to contingent factors, everybody can become
situationally impaired; due to cultural or language differences,
emotional or language barriers may ensue. In each of these situations,
decoupling user interfaces from backend services could enhance
interoperability both for people who rely on assistive technologies
and those who don't, improving the quality of the experience
regardless of one's own devices.

We welcome therefore papers that explore these issues and their
technological or methodological counterparts in the context of the
Web, papers that assess solutions, that show similarities or
differences between approaches, or that evaluate and compare methods
and tools.  As a result, topics of interests include (but are not
limited to):

- Accessibility-related issues of using one's own devices
- Developing accessible user interfaces for different devices
- Coping with different interaction modalities
- Web authoring guidelines and tools
- Mobile accessibility
- User modeling and the adaptive Web
- Adaptation and transformation of existing Web content
- Design and best practice to support Web accessibility
- Technological advances to support Web accessibility
- End user tools
- Accessibility guidelines, best practice, evaluation techniques, and tools
- Psychology of end user experiences and scenarios
- Innovative techniques to support accessibility
- Universally accessible graphical design approaches
- Accessible graphic formats and tools for their creation.

The Paciello Group Web Accessibility Challenge
The Sixth "Web Accessibility Challenge" is organized to give an
opportunity to researchers and developers of advanced Web
accessibility technologies for showcasing their technologies to
technical leaders in this area not only from academia and industry but
also as end-users.  To encourage and accelerate development of
innovative and practically usable Web accessibility technologies, the
Challenge is one part of the conference in which new experimental
systems and technologies are submitted, compared, and judged by our
independent panel of experts as to the most significant advance in
research technology in accessibility for that year.  Find more details

Google Student Awards
The W4A 2013 Organising Committee are delighted to announce that two
awards, each of up to US$1200 (including registration), are available
to support students to enable them to attend W4A 2013. We now invite
applications with a deadline of February 15th, 2013.  The Third
"Student Awards Programme" is organised to give an opportunity to
high quality students with limited funding to attend the W4A
Conference.  Our deadlines have been chosen to give as much time as
possible to allow successful applicants to make their travel and
accommodation arrangements.  Students with interests related to this
year's topic are encouraged but it is certainly not a requirement as
all students with an interest in accessibility technologies are
welcome to apply.  Find more details at

We will accept position and technical papers, and short communications.
Position papers should only be submitted as a communication of (up to
4-pages) whereas technical papers should be in full paper format (up to

5th ACM Web Science Conference (WebSci ’13)

May 1-5, 2014. Paris, France

Deadline for papers: Feb. 1st 2013

Web Science is the emergent science of the people, organizations, applications, and of policies that shape and are shaped by the Web, the largest informational artifact constructed by humans in history. Web Science embraces the study of the Web as a vast universal information network of people and communities. As such, Web Science includes the study of social networks whose work, expression, and play take place on the Web. The social sciences and computational sciences meet in Web Science and complement one another: Studying human behavior and social interaction contributes to our understanding of the Web, while Web data is transforming how social science is conducted. The Web presents us with a great opportunity as well as an obligation: If we are to ensure the Web benefits humanity we must do our best to understand it.

Call for Papers

The Web Science conference is inherently interdisciplinary, as it attempts to integrate computer and information sciences, communication, linguistics, sociology, psychology, economics, law, political science, philosophy, digital humanities, and other disciplines in pursuit of an understanding of the Web. This conference is unique in the manner in which it brings these disciplines together in creative and critical dialogue, and we invite papers from all the above disciplines, and in particular those that cross traditional disciplinary boundaries.

Web Science also offers a wide range of presentation modes in keeping with its diversity. The conference separates mode of presentation from mode of publication; for example, a striking new result might be presented as a poster or in a pecha kucha session for short, impactful results, and yet would still merit a full ten-page paper in the conference proceedings. The Web Science poster session, in particular, has been always been exceptionally strong.

Following the success of WebSci'09 in Athens, WebSci'10 in Raleigh, WebSci'11 in Koblenz, and WebSci ’12 in Evanston, we are seeking papers and research notes that describe original research, analysis, and practice in the field of Web Science, as well as extended abstracts that discuss novel and thought-provoking ideas and works-in-progress.

Possible topics for submissions include, but are not limited to, the following:

* Analysis of human behavior using social media, mobile devices, and online communities.
* Methodological challenges of analyzing Web-based large-scale social interaction
* Data-mining and network analysis of the Web and human communities on the Web
* Detailed studies of micro-level processes and interactions on the Web
* Collective intelligence, collaborative production, and social computing
* The architecture and philosophy of the Web
* The intersection of design and human interaction on the Web
* Economics and social innovation on the Web
* Governance, democracy, intellectual property, and the commons
* Personal data, trust, and privacy
* Web and social media research ethics
* Studies of Linked Data, the Cloud, and digital eco-systems.
* Web access, literacy, and development
* Knowledge, education, and scholarship on and through the Web
* People-driven Web technologies, including crowd-sourcing, open data, and new interfaces
* Digital humanities, webarchiving techniques and scholarly uses of Web archives
* New research questions and thought-provoking ideas


Web Science is necessarily a very selective conference with a rigorous review process. To accommodate the distinct traditions of its many disciplines, we provide three different submission formats: papers, notes, and abstracts.

Research Papers & Research Notes

Research papers and research notes should present new results and original work that has not been previously published. Research papers should present significant theoretical, empirical, methodological, or policy-oriented contributions to research and/or practice. Research notes should describe brief and focused research contributions that are noteworthy. Archival is optional.

Papers, which should be in English, can be up to 10 pages; notes up to 4 pages. All submissions should be formatted according to the official ACM SIG proceedings template (WebSci archive format at <> and submitted via EasyChair (<>).

Extended abstracts

Extended abstracts, which should be in English, can be up to 6 pages, and should be formatted according to the official ACM SIG abstract template (extended abstract format at <>) and submitted via EasyChair (<>).

Web Science Fringe Festival

The Web Science Fringe Festival takes an “unconference” approach to presenting work from the arts and sciences that pertains to Web Science but falls outside the conventional range of academic publication in the natural and social sciences. This might include, for example:

* performance art on, in, or about the Web
* painting, sculpture, or other media that comments on Web phenomena
* interactive drama and hyperdrama, either within or outside the Web
* electronic literature and virtual art
* pioneering web design
* location-aware and location-specific narrative
* augmented reality
* netart
* artistic data visualizations

This catalog is intended to be suggestive but not exhaustive. Unconventional presentations and interactions are encouraged. Limited assistance may be available to creators. Archival documentation is optional. French Language events are also encouraged.

The call for Web Science Fringe Events will follow in early February.

Review, Publication, and Presentation

The Web Science program committee consists of a senior program committee that covers all relevant areas of Web Science as well as regular program committee members from these areas. Each submission will be refereed by at least 3 PC members and one senior PC member, to cover both the research background of each submission as well as the necessary interdisciplinary aspects.

Review criteria for all types of submissions include significance, originality, presentation, validity, and the ability to stimulate discussion, with different emphases depending on the submission category to allow for consideration of all relevant works contributing to the advancement of Web Science.

All accepted papers, notes, and extended abstracts will appear in the Web Science 2013 Conference Proceedings and can also be made available through the ACM Digital Library, in the same length and format of the submission (although those wishing not be indexed can “opt out” of the proceedings). Regardless of the submission format, accepted submissions will be presented in one of three formats: 1) as a 20-minute presentation followed by discussion, 2) during one of the poster presentations and discussion sessions, 3) or as part of a panel discussion. Research papers, research notes, and extended abstracts are eligible for presentation in any of the three formats, depending on reviewer recommendations. Submissions that are thought-provoking and novel will be more appropriate for longer presentation, while those that are expected to stimulate discussion will be ideal for presentation in smaller groups or as posters.
