Multi-facade and Ubiquitous Web Navigation and Access through Embedded Semantics

Abstract

Abstract. Web content contains valuable information on the semantic structure of a site, which can be used to access and navigate the pages through ubiquitous computing environments. Semantic web approaches normally aim at modeling semantic relations and utilizing these models to provide enhanced functionality for humans or machines. In this paper we present an approach which focuses on using embedded semantics in order to achieve enhanced web access and navigation for the ubiquitous environments. Precisely we propose specifying and extracting microformat-based information within the web server and delivering it along the semantic structure of the site. We also describe our first prototype, the Semantic Web Component (SWC), and report on first experiences which evidence benefits in terms of less internet traffic and reducing the delivery of irrelevant information thus increasing the web accessibility as well as the navigability in ubiquitous environments.

Ubiquitous web navigation through harvesting embedded semantic data: A mobile scenario

“…First of all, developers need to provide vocabulary and syntax for each microformat to be transformed. Although the description language that we proposed earlier [29] can solve this problem, we disagree with unification by means of a unified syntax since a decision between microformats and RDFa is a tradeoff between simplicity (i.e., usability) and functionality.…”

“…SWC has been implemented to prove its applicability. A first and simpler variant was restricted to microformat [29]. The current version supports RDFa, eRDF and microformats (as long as the requirements are satisfied) and is based on PHP.…”
