This paper examines building of the course ontology for describing and organizing hyperlinked pedagogical content. The ontology is used to struc- ture and classify multimedia learning objects (MLO) in hyperlinked pedagogi- cal platform called HIP, and to assist students to search for lectures and other teaching materials in a reasonable time and more efficiently. In addition, this paper proposes a new approach to improve the classification performance by enhancing the information representation model using concepts from the peda- gogical course domain ontology. The model will automatically estimate weight of concepts within the ontology, and it will combine the weight with concepts’ importance which is calculated using Term Frequency Inverse Document Fre- quency – tf*idf algorithm. This paper is a work in progress. We are in process of creating and implementing the course ontology and an experiment will be conducted to evaluate the classification performance in terms of efficiency and effectiveness for the approach proposed in this paper.

The distance learning is one amongst them where students can access the information without being present in class. To improve dis- tance learning process, new means of communication and studying were introduced and new frameworks were created [1]. One such eLearning platform is Hyper Interac- tive Presenter – HIP [2]. HIP is a technology-rich pedagogical platform that uses combination of media elements to deliver the learning objects. The elements comprise of electronic docu- ments such as wiki pages and PDF documents, presentations, lecture videos, an intel- ligent pedagogical chat bot. In addition, it also provides navigational links, tagged keywords, and frequently asked questions (FAQ). A huge amount of information in HIP platform comes from different media modal- ities that need to be organized, structured and hyperlinked. Structuring and organizing such a wealth of information is labor intensive, prone to errors and a cumbersome task. Structuring information is required due to the need for classifying various
