Abstract

As access to educational video resources has been enhanced through search tools, recommender systems, and social channeling, users often encounter challenges in integrating diverse videos systematically, particularly when they possess a limited understanding of the topics at hand (e.g., novice learners). To address this challenge, we present ConceptCombo, a video navigating interface facilitating user explorations of unstructured video collections with conceptual structures and themes of social comments extracted from videos and visualized by the system. To help novices identify a series of quality videos to watch, ConceptCombo aims to deliver a structured overview of the video collection by systematically extracting a concept map from the video content, coupled with automatic summarization of user comments across the videos, as a treemap visualization. With ConceptCombo, novice users may adopt a synergistic approach to video exploration, underpinned by the semantic structure of the video content, social comments, and additional video metadata.
