Evaluación semisupervisada de sitios web

Un sitio web puede tener miles o incluso millones de páginas web. ¿Cómo se puede evaluar la accesibilidad de todo un sitio web? Es una tarea desafiante.

En el artículo Using Semi-supervised Group Sparse Regression to Improve Web Accessibility Evaluation se presenta una posible solución:
Web accessibility evaluation checks the accessibility of the website to help improve the user experiences for disabled people. Due to the massive number of web pages in a website, manually reviewing all the pages becomes totally impractical. But the complexities of evaluating some checkpoints require certain human involvements. To address this issue, we develop the semi-supervised group sparse regression algorithm which takes advantages of the high precision of a small amount of manual evaluation results along with the global distribution of all the web pages and efficiently gives out the overall evaluation result of the website. Moreover, the proposed method can tell the importance of each feature in evaluating each checkpoint. The experiments on various websites demonstrate the superiority of our proposed algorithm.
