Abstract

The large amount of data produced by automatic web accessibility evaluation has to be preprocessed in order to enable disabled users or policy makers to draw meaningful conclusions from the assessment. We study different methods for interpretation and aggregation of the results provided by automatic assessment tools. Current approaches do not meet all the requirements suggested in the literature. Based on the UCAB approach decribed in UWEM 0.5 we develop a new aggregation function targeted at the requirements
