Towards a study opportunities recommender system in ontological principles-based on semantic web environment

Abstract

A professional career selection is a complicated process for university student candidates and often little technical tolls are available for who aim to enter to superior education since it is necessary to consider incidence of a multiplicity of variables to obtain a satisfactory answer that comes near to idea that they have preconceived. These variables build up a complex relations map that requires formulation of an exhaustive and rigorous conceptual scheme. In this research a domain ontological model is presented as support to student's decision making for opportunities of University studies level of Venezuelan education For declaration of domain ontological model developed, information provided by two organisms (OPSU & CNU) is used. Both are responsible to design policies and strategies for superior education in Venezuela. The ontology is designed and created using Methontology approach, since this methodology offers possibility of improving progressive creation or captures and knowledge articulation, its elements and relations. In order to represent ontology Protege 3.1.1 tool is used, based on ontological language for Web: OWL (Web Ontology Language) and; finally, to accede and to visualize ontology, an application based on Semantic Web is developed. In field of computation, computer science and systems, concept of profiles or users models has many meanings and connotations, its first and greater diffusion arise with development and use of on-line increasing systems; however, they have gain great preponderance recently, not only to refer and/or to respond to passive user who approaches the system, but for possibility of taking care of a user stimulated and attracted by the system. In that sense, possibility of this personalized attention and/or recommendations from the system will be obviously conditioned by user context. Centered on possibility of giving that customized attention from which they must select an option between many, it is tried in future to construct a meta-ontology that integrates domain ontology with a user profile ontology, thus aiming towards to a Semantic Recommendation System under Multiagent approach in future, that could be useful to support students decision making process for career selection over different study opportunities in Higher Education level in Venezuela.
