  • Technical report TR03-02. Today's teaching and learning practices are evolving to leverage the continuously increasing information available on the web for all conceivable subject matters. This change is clearly visible in the field of Web-based learning. Instructors use on-line information sources, in addition to their textbooks, to collect content for their teaching material. They also use a variety of tools to prepare their presentations of this material, and make them, in turn, available on the web. Students also use the web to find more information on the subject matter that they study. This wealth of information presents a great challenge: how to provide an integrated, authoritative, extendible and shareable information collection of related multimedia education materials. The main issues of concern become easy access, fast efficient retrieval and relevant representation of different content such as text, HTML, PowerPoint, audio, video etc. In this paper, the author describes EduNuggets, an intelligent repository for multimedia educational material. EduNuggets has been designed to support the semantic integration of multimedia content to be distributed over the web. The paper discusses the user interface, tailored to instructors who maintain the collection, and learners who may use several strategies to access this material. The paper also presents a discussion on the two Information Retrieval (IR) techniques implemented in EduNuggets for effective exploration of the multimedia content, namely, Latent Semantic Indexing (LSI) and Naïve Bayesian Classification (NBC). Case studies performed to determine the validity and effectiveness of the NBC algorithm are also elaborated upon. Finally, the author describes a technology called Synchronized Multimedia Integration Language (SMIL) for authoring multimedia applications. In this project, SMIL is used for developing interactive multimedia resentations that include resources such as text, HTML, PowerPoint (PPT) and images. These presentations can then be played on Windows or Unix platforms and can enhance the repertoire of material available to instructors and students. The paper concludes with plans for future research. | TRID-ID TR03-02
