Enhancing ontology-based educational content search service with competency

Abstract

In this paper we present a methodology for designing competency based web search framework using ontology to acquire the learning contents that meets the individuals' competency. We used ontology with OWL-DL to built competency ontology, content ontology and domain ontology to implement competency based contents search system. The basic ontology-based search system, however, lacks the method of ranking the search results. To present more appropriate learning contents for the learner, we applied competency clustering to rank the search results.
