An Ontology for representing Context in User Interaction for enhancing Web Accessibility for All

Today, users of web-based platforms are generally heterogeneous and have different needs, and this is likely to increase in the future. The user interfaces of these systems are mostly direct manipulation interfaces. These Interfaces can considerably benefit from the semantic of context, it can adapt the utility of interaction styles and display modes depending largely on the surrounding environment, the user’s needs and the characteristics of on-line resources. In order to provide means for that, first we have to define how to better represent contextual information, second we have to reason about these information. In that respect, ontologies are an interesting approach since they enable reasoning, reusability and knowledge sharing. In this paper, we propose CO a Context Ontology using OWL to formally represent context in user interaction processes, that enhances the web accessibility.
