A Semantic-web based framework for developing applications to improve accessibility in the WWW

摘要

One of the biggest issues the World Wide Web (WWW) community has to overcome is accessibility for all. The rapid expansion of the WWW using problematic web authoring practices, together with the dominance of the desktop metaphor in web page design has raised many WWW accessibility problems for people with disabilities. In this paper we present a what may be termed as a "Semantic Web application framework" which allows different applications to be designed and developed for improving accessibility of the WWW. Apart from the architecture, the tools and the technologies that compose the framework, the key idea of the framework is that it aims at promoting the idea of creating a community of people federating into groups each playing a specific role: ontology creators creating concepts using an ontological approach to describe various elements of the WWW, annotators using concepts to annotate specific pages, user-agent developers creating tools based on the framework, and finallyend-users (people with disabilities) that use these tools for their benefit. Within the proposed framework, these groups cooperate and interact with each other, having as their ultimate goal the improvement of WWW accessibility.
