Frequently asked questions

How do the autotaggers work?

First, we extract timbral and rhythmic features for each of the clips. Then we train support vector machines (SVMs) on these feature vectors using the data from the MajorMiner game. You can read about it in our paper in the Journal of New Music Research.

Did you train and test on the same data?

No, all autotagging results are shown for a separate set of music than they were trained on.

Why don't you have autotags for my favorite tag?

We can only train an autotagger if players of the MajorMiner game have identified enough examples of it. "Enough" generally means 30-50 clips that have been verified by two people as relevant to a tag. So if your favorite tag isn't up there yet, get playing and find some good examples of it.

If I play the game now, will my tags get incorporated into the search?

Yes they will. Well, they will be incorporated into the human search on MajorMiner within a day. They won't be incorporated into the search here until we re-train the autotaggers, which only happens occasionally.

What order are the autotags in on the autotag page?

They're sorted from the most accurate to the least. This was determined by measuring classification accuracy on labeled clips in the test set.
