TunkRank and Retweet Rank

February 17th, 2009 · 3 Comments · General

While we wait for Jason to iron out the bugs in his TunkRank implementation, I’ve been thinking about the relationship between TunkRank and retweet rank as influence measures.

Here’s my thought: TunkRank assumes in its model that, if X reads a tweet from Y, then thereโ€™s a constant probability p that X will retweet it. If this assumption holds true, then the TunkRank of X should be roughly proportional to the retweet rank.

Of course, one of the reasons this assumption might fail is that X is using bots (or bot-like people) to game his or her retweet rank. It’s also possible that the TunkRank assumption about a constant probability of retweeting is too simplistic.

But I’m intrigued at the idea that, subject to the assumptions of its model, TunkRank acts as a sort of ungameable retweet rank.

    I had a look at the TurkRank and got a 2 Percentile??

    not sure what that is suppose to indicate?

    make that TunkRank (still need coffee ๐Ÿ™‚ )

    I think it means that it’s still a work in progress. ๐Ÿ™‚ I’m just an excited / impatient customer; I haven’t been involved with the implementation.
