The continuous growth of digital media creation has led to the large abundancy of virtual information available in the form of multimedia content. General search engines like Google and Yahoo are widely accessible, but they have their limitations in multimedia search. For instance, the results returned from these tools mainly come from the pre-defined titles and description of the multimedia files, which can be deceptive and inaccurate at times. Furthermore, entertainment media are often prioritized over educational subjects due to their mass popularity, making it hard for students to find scholastic content using these common search engines. In order to allow efficient access to these content-rich audiovisual documents, a more specialized application has to be designed and developed. Hence, this project aims to develop a system, which would allow the students to easily browse and retrieve required audiovisual information via a search-based web application. The information returned will come not only from titles and descriptions, they will also come from the actual transcript of the media files. A more semantic view of the concepts in a specific domain will also be provided in the form of a concept tree, which can be used for navigation and search. The proposed system, known as LectsSearch, is built on a Model-View-Controller (MVC) framework. In this report, the author will justify how the implementation of the framework has allowed the system to be highly scalable and flexible. Technologies like PHP, Javascript, JQuery and AJAX were also utilized to make the interface much more dynamic and user friendly. Lastly, a conclusion of what has been achieved, followed by the enhancements that can be made in the future will be summarized.
