YouTube Snapshot 080621
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 June 2008 to 21 June 2008 (the log's title line reads 'BFS crawl'). It started from 179 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 55,535 videos the crawl visited (179 at depth 0, 1,542 at depth 1, 8,552 at depth 2, 45,262 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 (710,335 links from 35,554 videos, with the position in the list as rank). The links lead to 387,840 distinct videos, of which 332,451 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.
