Agents

  • Abstract

    This paper describes the use of Intelligent Agents and Ontologies to implement knowledge navigation and learner choice when interacting with complex information locations. The paper is in two parts: the first looks at how Agent Based Semantic Technology can be used to give users a more personalised experience as an individual. The paper then looks to generalise this technology to allow users to work with agents in hybrid group scenarios. In the context of University Learners, the paper outlines how we employ an Ontology of Student Characteristics to personalise information retrieval specifically suited to an individual’s needs. Choice is not a simple “show me your hand and make me a match” but a deliberative artificial intelligence (AI) that uses an ontologically informed agent society to consider the weighted solution paths before choosing the appropriate best. The aim is to enrich the student experience and significantly re-route the student’s journey. The paper uses knowledge-level interoperation of agents to personalise the learning space of students and deliver to them the information and knowledge to suite them best. The aim is to personalise their learning in the presentation/format that is most appropriate for their needs. The paper then generalises this Semantic Technology Framework using shared vocabulary libraries that enable individuals to work in groups with other agents, which might be other people or actually be AIs. The task they undertake is a formal assessment but the interaction mode is one of informal collaboration. Pedagogically this addresses issues of ensuring fairness between students since we can ensure each has the same experience (as provided by the same set of Agents) as each other and an individual mark may be gained. This is achieved by forming a hybrid group of learner and AI Software Agents. Different agent architectures are discussed and a worked example presented. The work here thus aims at fulfilling the student’s needs both in the context of matching their needs but also in allowing them to work in an Agent Based Synthetic Group. This in turn opens us new areas of potential collaborative technology. Details

  • Abstract

    The exploration of social artifacts for the disabled is an important and timely issue. The affordances of new technologies like the Semantic Web allow more intelligent handling of educational learning resources that open up the potential of personalisation of services to individuals. Contemporary legislation calls for “reasonable adjustments” and “reasonable accommodation” to be made to services in order to accommodate the needs of disabled people. Here, the authors examine, from a design perspective, how this might be done in the context of higher education. Specifically, they advocate a design based upon an ontology-based personalisation of learning resources to deliver to students’ real needs. To this end, so far little effort has been directed towards disabled students in higher education. The authors note some of the problems and issues with online assistive/adaptive technologies and propose a methodological fix. Here, they propose an ontology-based methodology for a Semantic Web community of agents that personalises learning resources to disabled students in higher education, specifically highlighting a disability-aware Semantic Web agency development methodology. The authors also present the results of usability evaluation of the implemented visual interface with some disabled and non-disabled students.

  • Abstract

    Disability legislations such as the Disability Discrimination Act 1995, 2005 and Americans with Disabilities Act 1990 call on service providers to make “reasonable adjustments” and “reasonable accommodation” respectively to their services in order to accommodate the needs of disabled people. Higher education institutions as service providers can respond through their services. Nevertheless, there is an increasing challenge in using digital media to deliver services due to the numerous problems associated with inaccessibility of some online systems with assistive/adaptive technologies. Personalisation is a solution to such problems as it provides content to students based on their needs. However, very little of such personalisation has been targeted towards disabled students and hence, this paper proposes an ontology approach for a semantic web community of agents that personalises services to disabled students in higher education. We present the architecture of such an agency, including a disability-aware semantic web agency development methodology and also present the ADOOLES ontology employed for such personalisation.
