Before revision:  The DAISY system utilizes machine learning techniques like video synchronization and gunshot temporal localization URLanize the unstructured social media videos and quickly localize gunshot in the videos. It provides a web interface for human-in-the-loop verification to ensure accurate estimations.
After revision:  The DAISY system utilizes machine learning techniques like video synchronization and geolocation to order unstructured videos lacking metadata over time and space, and sound detection algorithms. Both this gunshot localization tool and the previous systems it incorporates are run through a web interface for human-in-the-loop verification to ensure accurate estimations.
