YouTube Snapshot 0420
A crawl of YouTube made by Xu Cheng, Cameron Dale and Jiangchuan Liu of Simon Fraser University, which the crawler's log dates from 19 April 2007 to 20 April 2007 (the log's title line reads 'normal crawl'). It started from 337 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 112,259 videos the crawl visited (337 at depth 0, 2,683 at depth 1, 13,546 at depth 2, 95,693 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 (2,179,497 links from 110,334 videos, with the position in the list as rank). The links lead to 1,056,836 distinct videos, of which 944,644 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.
