Towards an Ontology-Based Model for User Profile Representation in a Cloud Infrastructure

Abstract

This paper presents an approach for the semantic representation of user profiles through an ontology conducted in the scope of the Cloud4all project. Employing the cloud computing paradigm, Cloud4allaims torealize a global public inclusive infrastructure that will reinforce accessibility of information and communication technologies(ICT). The proposed ontology aims to provide the required representation formalism to sufficiently express personal user needs and preferences based on domain knowledge and the association of interaction-related concepts in order to support automatic reasoning mechanisms for user profile management.

Metadata and universal access in digital library environments

“…As explained in the project documentation [5], GPII is believed to create a cloud-based platform where users can register their needs and preferences and accessibility developers create and upload tools that address those needs. In addition to user needs, the GPII is supposed to contain information about assistive technologies, devices, and uses (Koutkias et al, 2014). The intention is to invoke accessibility features in any device the user may use anywhere and adapt the interface automatically (e.g., screen would change to large print, high-contrast, etc.…”

“…Koutkias et al (2014) discussed such projects like Clould4All[1] and GPII [2] , which aimed at creating cloud-based infrastructure for ensuring cheaper and ubiquitous accessibility solutions, and identified one "major gap": lack of common terminologies and models enabling the semantic description of both needs and preferences of users and available ICT artifacts. In other words, they indicated the need for standard procedures for resource description as well as user profiling.…”

“…The shortcomings associated with the guidelines-based approach seem to have swayed the interest of newer generation endeavors toward the adaptive and auto-personalization approaches, which seek to improve accessibility by matching resources with users' needs and preferences. Koutkias et al (2014) discussed such projects like Clould4All [1] and GPII [2], which aimed at creating cloud-based infrastructure for ensuring cheaper and ubiquitous accessibility solutions, and identified one "major gap": lack of common terminologies and models enabling the semantic description of both needs and preferences of users and available information and communication technology artifacts.
