Abstract:
Title: Re-Thinking Web Accessibility
Abstract: Previous studies of Web accessibility have found little evidence for the impact of the Web Content Accessibility Guidelines, at least over the relatively short time periods examined. This talk presents new data from over 100 top-traffic and government websites over the 14 years since the publication of WCAG 1.0. Automated analyses of WCAG Success Criteria again found high percentages of violations overall. Unlike earlier studies, however, improvements on a number of accessibility indicators were found, with government sites being less likely than top-traffic non-government sites to have accessibility violations. Examination of the causes of success and failure suggests that improvements may be due, in part, to changes in website technologies and coding practices rather than a focus on accessibility per se. Possible contributors to improving accessibility include the use of new browser capabilities to create more sophisticated page layouts, a growing concern with improved page rank in search results, and a shift toward cross-device content design. Understanding these examples may inspire the creation of additional technologies with incidental accessibility benefits. The talk concludes with a look at how adapting even non-compliant Web content can improve accessibility for a broad range of people.
Short bio: Vicki Hanson is Professor of Inclusive Technologies at the University of Dundee, and Research Staff Member Emeritus from IBM Research. She has been working on issues of inclusion for older and disabled people throughout her career, first as a Postdoctoral Fellow at the Salk Institute for Biological Studies. She joined the IBM Research Division in 1986 where she founded and managed the Accessibility Research group. Her research examines the changing nature of technologies and the motivations and barriers to their use by populations in danger of digital exclusion, focusing on issues related to aging, cognition, and language. Applications she has created have received multiple awards from organizations representing older and disabled users. She is Past Chair of the ACM SIG Governing Board, Past Chair of ACM Special Interest Group on Accessible Computing (SIGACCESS), and is the founder and co-Editor-in-Chief of ACM Transactions on Accessible Computing. Prof Hanson is a Fellow of the British Computer Society and was named ACM Fellow in 2004 for contributions to computing technologies for people with disabilities. In 2008, she received the ACM SIGCHI Social Impact Award for the application of HCI research to pressing social needs. She currently is the ACM Secretary/Treasurer. We recently received the 2013 Anita Borg “Woman of Vision Award for Social Impact” and was just elected Fellow of the Royal Society of Edinburgh.

Upcoming Events
Research data repositories and tools for human genomics data sharing
Inform the human research community of the status and availability of BioData.pt Local EGA and discuss its need and usability challenges.
The European Genome-phenome Archive (EGA) is a repository for all sequence and genotype experiment types, including case-control, population, and family studies. The EGA will serve as a permanent archive that will archive several levels of data, including the raw data (which could, for example, be re-analysed in the future by other algorithms) as well as the genotype calls provided by the submitters.
Responding to national regulations over human data sharing and other constraints, BioData.pt deploys and operates a Local EGA instance and tools that allow data discovery of genomic and phenoclinic data, following the GA4GH standard and international best practices.
This workshop aims at informing the human research community of the status and availability of BioData.pt Local EGA and discuss from several perspectives its need and usability challenges.

The 13th Lisbon Machine Learning School | LxMLS 2023
The Lisbon Machine Learning Summer School (LxMLS) takes place yearly at Instituto Superior Técnico (IST). LxMLS 2023 will be a 6-day event (14-20 July, 2023), scheduled to take place as an in-person event.
The school covers a range of machine learning topics, from theory to practice, that are important in solving natural language processing problems arising in different application areas. It is organized jointly by Instituto Superior Técnico (IST), a leading Engineering and Science school in Portugal, the Instituto de Telecomunicações, the Instituto de Engenharia de Sistemas e Computadores, Investigação e Desenvolvimento em Lisboa (INESC-ID), the Lisbon ELLIS Unit for Learning and Intelligent Systems (LUMLIS), Unbabel, Zendesk, and IBM Research.
Check online for information about past editions: LxMLS 2011, LxMLS 2012, LxMLS 2013, LxMLS 2014, LxMLS 2015, LxMLS 2016, LxMLS 2017, LxMLS 2018, LxMLS 2019, LxMLS 2020, LxMLS 2021, LxMLS 2022 (you can also watch the videos of the lectures for 2016, 2017, 2018, and 2020).
31st International Conference on Information Systems Development (ISD 2023)
The 31st International Conference on Information Systems Development (ISD 2023) conference provides a forum for research and developments in the field of information systems. The theme of ISD 2023 is “Information systems development, organizational aspects and societal trends”. New trends in developing information systems emphasize the continuous collaboration between developers and operators in order to optimize the software delivery time. The conference promotes research on methodological and technological issues and how IS developers and operators are transforming organizations and society through information systems.
The ISD 2023 conference held this year also provides an opportunity for researchers and practitioners to promote their research, practical experience, and to discuss issues related to Information Systems through papers, posters, and journal-first paper presentations.
ISD 2023 will be hosted by Instituto Superior Técnico, in Lisbon, Portugal, on August 30–September 1, 2023.
