I'm looking for a way to identify (as many as possible) YouTube videos on a certain topics based on a keywords occurring in their titles.
YouTube Data API provides a way to search for videos based on the keywords but limits results up to 500 titles only.
Common Crawl indexes YouTube.com domain but it contains information only about page URLs and not its HTML <title>
while YouTube.com videos do not have their titles in URL (basicaly it's https://www.youtube.com/watch?v=v01QZUxYg62
).
There's YouTube 8M dataset of segmented videos but it seems an overkill to just get the titles. Is there any other corpora of up-to-date YouTube video titles?
