Abstract :
This research addresses some of the
important issues related to web accessibility in the
context of blind users. The problems of Web data
accessibility and navigation for blind users have become
an active research field for the past decade. Many
techniques have been created to solve them, some are
hardware-based and others are software based. Yet, the
web is rapidly evolving toward the far-anticipated
Semantic Web (SW): a revolutionary vision extending
Web information with well-defined meaning so that it
becomes more easily accessible by human users and
automated processes. As a result, SW technological
breakthroughs such as ontologies and semantic data
description, as well as data representation and
manipulation technologies (i.e RDF, OWL, and
SPARQL) are being recently explored to improve data
accessibility for blind Web surfers. This research, briefly
explores existing studies targeting Web data accessibility
for blind users ranging from traditional techniques
(Braille output, screen readers, etc.) to semantically
enhanced techniques (using Speech and alternative
speech-based interfaces for human-computer
interaction). A semantic web for the blind was designed
and implemented using JAVASCRIPT, HTML, CSS,
and MySQL. After the evaluation of the developed
framework, the result of the research revealed that it has
load-time as 75%, success ratio of 0.93, repository size of
65%, and CPU-time up to 80% and comparing it to the
existing performance evaluation, it can be said that the
proposed developed framework out performed.
