Hierarchical Mind Map Generation from Video Lectures

Abstract

With a steep increase in awareness and advancement in technologies over the past decade the standards and content of curriculum receives constant upgradation. In the current scenario, students often find it exhausting to learn the voluminous matter presented to them. In these cases, it is essential to find an approach beyond conventional means to prove as an aid while studying. One such tool is a Mind Map. Although the tool is proven to be effective, the process of creating a Mind Map is found to be laborious. Our inventive software is designed to obtain useful information from a video lecture. This is done by utilizing the content obtained by crowd sourcing, splitting the video into multiple subtopics and then transcribing the same. The tool then processes this data and extracts keywords relevant to the area of discussion. Following this, the tool organizes these key phrases so that it can be represented as a hierarchical Mind Map. Each node contains necessary phrases and all nodes and these nodes are carefully ordered. Additionally, the Map is made interactive and dynamic in order to enhance the students' experience.
