Abstract

We show that a recently introduced lexical quality measure is also valid to measure textual Web accessibility. Our measure estimates the lexical quality of a site based in the occurrence in English Web pages of a set of more than 1,345 words with errors. We then compute the correlation of our measure with Web popularity measures to show that gives independent information. This together with our previous results implies that this measure maps to some of the WCAG principles of accessibility.
