Pedagogical document classification and organization using domain ontology

Abstract

One of the challenges faced by today’s web is the abundance of unstructured and unorganized information available on the Internet in form of educational documents, lecture notes, presentation slides, and multimedia recordings. Accessing and retrieving the massive amount of such resources are not an easy task, especially educational resources of pedagogical nature. Much of the pedagogical content available on Internet comes from blogs, wikis, posts with little or no metadata, that suffer from the same dilemma. The content is out there but way out of the reach of the intended audience. For content to be readily available, it has to be properly organized into different categories and structured into an appropriate format using metadata. This paper addresses this issue by proposing an automated approach using ontology-based document classification. The paper presents a case study and describes how our proposed ontology model can be used to classify educational documents into predefined categories.
