We present a novel video browsing and retrieval system for edited videos, based on scene detection and automatic tagging. In the proposed system, database videos are automatically decomposed into meaningful and storytelling parts (i.e. scenes) and tagged in an automatic way by leveraging their transcript. We rely on computer vision and machine learning techniques to learn the optimal scene boundaries: a Triplet Deep Neural Network is trained to distinguish video sequences belonging to the same

The system also features a user interface build as a set of extensions to the eXo Platform Enterprise Content Management System (ECMS) 1 . This set of extensions enable the interactive visualization of a video, its automatic and semi-automatic annotation, as well as a keyword-based search inside the video collection. The platform also allows a natural integration with third-party add-ons, so that automatic annotations can be exploited outside the proposed platform.
