Extract
The video, its metadata and its comments; the audience measured again at day 1, 7 and 30.
Detection, extraction and audience snapshots
Collection, transcription and sentence classification are carried out by the project’s network of computers. The central server hosts the database and this site. It also computes the vectors used for meaning-based search and writes the automatic texts.
-
every 6 h
Detection, every six hours
The public RSS feeds of each YouTube channel (long videos, Shorts, live streams) give new videos, their exact publication date and their view count.
-
every week
Full listing, every week
A full listing of each channel’s videos is taken every week. It catches videos missing from the feeds and reveals deletions. TikTok accounts, which have no RSS feed, are covered by this listing only.
-
within the hour
Metadata and comments
Within an hour of detection, a video less than nine days old moves to the front of the collection queue: metadata, first view count and comments. Older videos are extracted in batches.
