It seems like if you're going to support querying you should also support "just give me all the content tags", even if that's implemented as running all the individual queries. Especially for example number 1 you're going to find that publishers aren't thinking "Do I have automotive videos to package up for a car brand?", they're thinking "I have no idea what content I have in my network, what broad categories does it fall into?".
My employer, SET Media [1], has built out our own ML / CV system that applies a taxonomy of a bit over 1000 tags to several million videos. We add new videos and re-compute existing results multiple times a day. It's been invaluable for us to be able to query for both a specific tag as well as to see all the tags (and their confidences) that are applied to a video.
