From a discussion on Hacker news:<\/a><\/p>\n

Youtube does have automatic transcription for videos. It’s not too hard to link this to a topic hierarchy (maybe they already do this). It seems like a hard problem at their scale, since unlike Spotify, the list of genres isn’t knowable.<\/p>\n

I’ve been building a search engine for lectures as a research project. For a small list of videos I find that browsing topic taxonomy is really nice compared to the recommenders that try to guess your intent.<\/p>\n

There are commercial systems for automatically tagging the text (e.g. Watson) which hierarchies which don’t go into niche areas – e.g. the Watson taxonomy tagger does 1,000 tags.<\/p>\n

For more niche topics, I’ve explored Watson’s entity recognition system, e.g. to recognize the names of diseases. The advantage is it picks up terms it hasn’t seen- The problem is you can only identify entities that someone has trained a system to recognize.<\/p>\n

The UI challenges are interesting as well. If spotified identified 100 genres that interested me, they could pick any arbitrary subset of playlists and I’d be pretty happy. If I used youtube to get home repair videos, and then they showed me videos about repairing parts of my house that aren’t broken, it’d get pretty irritating.<\/p>\n","protected":false},"excerpt":{"rendered":"
