Usability and transparency in the design of a tool for automatic support for web accessibility validation
Iannuzzi N., Manca M., Paternò F., Santoro C.
The importance of guaranteeing accessible Web applications is becoming widely recognised, and supported by national and international legislation. This implies an increasing need for large scale validations, which can be achieved only through automatic support. Thus, there is a need for a new generation of accessibility validation tools able to check against the continuously evolving guidelines and report any issues revealed, considering that their results will be used by many people with varied backgrounds and goals. Such tools should be able to support monitoring of Web sites' accessibility, provide user-friendly information suitable for various purposes, and be transparent in terms of what they are actually able to evaluate in order to elicit the right expectations from their users. They should also consider how the technologies for implementing Web sites have evolved in recent years. In this paper, we provide a description of the requirements and design dimensions that characterise such tools in order to address emerging needs, providing indications on whether and how several existing validation tools support them, and present how we have addressed and implemented them in a specific tool. We also report on a first usability test of such tool, which has provided encouraging feedback.Source: Universal access in the information society (Internet) (2022). doi:10.1007/s10209-022-00948-x

Large scale automatic web accessibility validation of Italian public administration web sites
Iannuzzi N., Manca M., Paternò F., Santoro C.
To support large-scale validation, we have extended the MAUVE++ tool . When we started this study, it was a tool aiming at identifying accessibility errors on websites in order to facilitate their correction; and for this reason, it focused on presenting results in terms of violated techniques (which is the most detailed level), and it was able to validate only small groups of pages associated with a Web site. For such reasons, we had to face three different challenges to perform a large-scale validation: 1) to report the validation results in a more abstract manner and higher level granularity to facilitate their interpretation from a monitoring perspective, 2) to update the crawling and the validation process to be able to scale-up to large numbers of pages and sites, 3) and to support validation of Web sites implemented with modern technologies.

Large scale automatic web accessibility validation
Iannuzzi N., Manca M., Paternò F., Santoro C.
Digital accessibility is considered an important aspect to allow all people, including those with permanent or temporary disabilities, to access the continuously increasing number of digital services. This raises the need for tools able to provide support for monitoring the level of accessibility of a large number of websites in order to understand their actual level of accessibility, and identify the areas that need more interventions for their improvement. We present how we have extended a tool for accessibility validation for this purpose, and the results that we obtained in the validation of about 2.7 million Web pages of Italian public administration Web sites.Source: GoodIT 2023 - 3rd ACM International Conference on Information Technology for Social Good, pp. 307–314, Lisbon, Portugal, 06-08/09/2023

MAUVE++
Manca M., Paternò F., Santoro C., Iannuzzi N., Broccia G., Pulina F.
MAUVE++(Multiguideline Accessibility and Usability Validation Environment) is a system to evaluate accessibility of websites by checking their HTML and CSS code through guidelines, it provides validation results for different types of stakeholders, and supports validation of W3C WCAG 2.1 guidelines.
