Representación formal de la estructura lógica de sitios web, y su aplicación a un navegador web multilingüe basado en diálogo

Abstract

Un problema bien conocido de HTML es el pobre contenido semántico de sus etiquetas, dejando la tarea de interpretar los distintos elementos y secciones que conforman el sitio web al usuario. Frente a ello, iniciativas como la web semántica proponen percibir la web como una red de ontologías de manera que el significado de un sitio web sea computacionalmente accesible. Entre ambos extremos, en este trabajo se propone un formalismo denominado Web Logic Forms (WLF) que permite representar de manera formal cómo la información esta estructurada en un sitio web, pero sin entrar en la representación del contenido textual del sitio. De esta manera es posible que el sitio web sea presentado de una manera conveniente al usuario en otros caminos distintos al meramente visual. Es por ello que la aportación aquí propuesta no consiste en permitir realizar nuevas y complejas tareas sobre la web tal como persigue la web semántica, sino dotar de la formalidad suficiente a una página expresada en HTML para que permita al navegador u otro software conocer cómo se distribuye y estructura la información allí codificada. En esta línea en se propone un navegador web basado en diálogo apropiado para personas invidentes o para su uso en dispositivos portátiles.

HTML tags have poor semantic meaning because the final user of the web is supposed to be a human being with several skills. The user has understand the web site by means of natural language, visual features of text and images, etc. Semantic web deals to create a net of ontologies into the web by describing the meaning of the site in a more formal way. In this work, we propose a formal representation named Web Logic Forms (WLF) between HTML and semantic web in order to represent the logic structure of a web site. Thus, the navigator is able to present the information of the site in a more appropriate way for a given user. By example, the navigator was able to present the information without any visual object, by “reading” the information by using structural aspects of the site such as headings, sections, news, etc. In order to test WLF, we propose a web navigator based on dialog suitable for blind persons or navigation by using small portable devices such as PDAs or smart phones.
