10. Multimodal Analytics Dashboard for Story Detection and Visualization

The InVID Multimodal Analytics Dashboard is a visual content exploration and retrieval system to analyze user-generated video content from social media platforms including YouTube, Twitter, Facebook, Reddit, Vimeo, and Dailymotion. It uses automated knowledge extraction methods to analyze each of the collected postings and stores the extracted metadata for later analyses. The real-time synchronization mechanisms of the dashboard help to track information flows within the resulting information space. Cluster analysis is used to group related postings and detect evolving stories, to be analyzed along multiple semantic dimensions such as sentiment and geographic location. Data journalists can not only visualize the latest trends across communication channels, but also identify opinion leaders (persons or organizations) as well as the relations among these opinion leaders.
