YouTube Snapshot 080721
A crawl of YouTube made by Xu Cheng, Cameron Dale and Jiangchuan Liu of Simon Fraser University, which the crawler's log dates from 21 July 2008 to 21 July 2008 (the log's title line reads 'BFS crawl'). It started from 174 seed videos and followed each video's list of related videos breadth-first down to depth 3. The package holds one record for each of the 46,868 videos the crawl visited (174 at depth 0, 1,417 at depth 1, 7,226 at depth 2, 38,051 at depth 3; uploader, age, category, length, number of views, average rating, number of ratings and number of comments) and one directed link for each entry in a visited video's list of related videos (565,222 links from 28,280 videos, with the position in the list as rank). The links lead to 335,287 distinct videos, of which 288,551 were not themselves crawled in this crawl and so have no record. It is one of the crawl snapshots of the collection youtube-sfu-collection, and the single row of snapshots describes the crawl from its log.
