    I'd totally be willing to take on part of it.

    How would this work? I'd be willing to participate so long as someone can explain to the idiot (me) what we're doing.

    Can I suggest just organizing it by the stated weight class for the subbing fighter? Its not perfect, but the problem becomes tractable for a small loss in accuracy.

    Hey, fellas. I wrote up the fighter-rating methodology and produced some new graphs here.

    WarWheel: the data files are linked at the bottom of the piece if you want to have a go.

    Everyone else: PM me if you'd be willing to help annotate the UFC data with per-fight weight classes. If we can get this done, I'll build an always up-to-date web application that shows who the top fighters are by weight class, both all-time and currently active.

    That's a fantastic presentation of data. And it's consistent with subjective opinion for the most part. Is there a way to include a time factor? Fighters wax and wane during their careers (e.g. CroCop today is not, seemingly, CroCop in 2004).

    Thanks!

    I plan to build a little app that allows one to view ratings within a time window (who was the best from 2001-2004, for instance), and possibly some animations showing fighters drifting up and down in the ratings over time. The latter would be a nice way to extract career narratives from the raw data.

    You're completely correct. I'll go check the data for corruption and re-run the rating algorithm.

    Thanks Jack.

    Just thinking out loud -- There are two ways to deal with circular phenomena of this type: One would be to use a formalism that allows circularity to be expressed in a non-degenerate fashion (ie:hypersets), and the other, to classify the individauls into sequential "orders" ala the ramified theory of types.

    The latter approach would be productive, I think. For example instead of regarding Ali, Forman and Frasier as a RPS-type game, one could distinguish between the Frasier that beat Ali (FRASIER-0308071) from the Frasier that lost to Forman (FRASIER-012273). When ALI-103074 beats Forman103074, there is no circularity introduced by the fact the Forman>Frasier>Ali>Foreman, because the first Forman is a different entity than the second.
