I am providing class label to the ELKI elki-bundle-0.7.1

It provides a lot of statistics such as below but i cant find info about what are they?

I know f1-measure, precision and recall however how can there be multiple measures? Aren't they supposed to be calculated according to the result of clustering?

Thank you
