Web Images Relevance and Quality: User Evaluation.

The growth of the Web has been exponential in the last two decades. Currently, the WWW offers a large volume of information and services. Although the user has access to this profusion of information, there are different levels of quality in the information and its publication, which highly influences the understanding. In this paper, we have attempted to establish a relationship between the relevance of web images and their quality. First, a comparative analysis of previous research works in the literature has been carried out. Two methods of web page evaluation have been compared, on the one hand, the evaluation of the end-users of the page, and on the other hand, the heuristic evaluation, carried out by accessibility experts. A user study has been carried out with objective and perception questions. The results obtained with both evaluation methods were similar, agreeing on the characteristics which influence the relevance and quality of the web images. This will help web designers to improve the quality by considering only the relevant content of a web page, without relying on expert judgment.
