The use of web applications has extremely increased in the last few years. However, some groups of users may experience difficulties
when accessing them. Many different sets of accessibility guidelines have been developed in order to improve the quality of
web interfaces. Some of them are of general purpose whereas others are specific for user, application or access device characteristics.
The existing amount of heterogeneous accessibility guidelines makes it difficult to find, select and handle them in the development
process. This paper proposes a flexible framework which facilitates and promotes the web accessibility awareness during all
the development process. The basis of this framework is the Unified Guidelines Language (UGL), a uniform guidelines specification
language developed as a result of a comprehensive study of different sets of guidelines. The main components of the framework
are the guidelines management tool and the flexible evaluation module. Therefore, sharing, extending and searching for adequate
accessibility guidelines as well as evaluating web accessibility according to different sets of guidelines become simpler

    ABSTRACT: While automatic tools are not intended to replace human judgement they are crucial in order to develop accessible web sites. The release of WCAG 2.0 entails that the existing plethora of accessibility review tools will have to be updated. This paper presents an evaluation framework for making the transition from WCAG 1.0 to WCAG 2.0 in a less painful way. A framework is thus proposed that allows developers to create new guidelines, and update or reuse the existing ones. A case study to test its feasibility has been carried out by incorporating WCAG 2.0 guidelines into the framework. The results are satisfactory, since 55% of the automatic and 16% of the semi-automatic ones could be expressed using the framework. Therefore, it is demonstrated that even if the framework does not fully support the transition process, at least it makes it less burdensome. Moreover, by analyzing WCAG 2.0 we have learnt how to extend the existing tools in order to provide greater coverage and thus increase their effectiveness.

    ABSTRACT: Due to the extensive amount of information regarding web accessibility developed in recent years, developers find difficulties for creating accessible web applications. Accessibility knowledge management tools can facilitate this task. However, existing tools do not provide enough support to all the activities of the development process. In this sense, developers have to use diverse tools focused on different stages and they are also required to search for accessibility information from different sources. The aim of this paper is to present a framework for managing accessibility guidelines. It serves as a central repository where developers can search for accessibility guidelines, define new guidelines, and share them with other developers and evaluating them automatically. Therefore, this framework facilitates developers’ tasks as it gives support to several activities of different stages throughout the development process.

    ABSTRACT: This paper presents a framework and system to evaluate the accessibility of web pages according to the individual requirements of users with disabilities. These requirements not only consist of users' abilities, but also users' assistive technologies and the delivery context. In order to ascertain interoperability with other software components, user requirements are specified taking advantage of the extensibility of the W3C CC/PP recommendation and other feature- specification vocabularies. An evaluation tool capable of understanding these specifications generates evaluation reports that are tailored to the user's individual needs. Quantitative accessibility measures resulting from personalized evaluation reports can be used to improve the web browsing experience for users with disabilities, such as through adaptive navigation support and by sorting the results of search engines according to users' personal requirements. In addition, developers benefit from personalized evaluations when developing websites for specific audiences.
