I am student on master studies in Production and Logistics. For some 2-3 mounts I have worked in one group which had the task to make cluster analyses. Here I have used Jaccard (or Tanimoto, I presume we are talking about the same thing) coefficient. I did not make than any java cods for that, but that is something what I can do. Or I can explain to You on one example how the algorithm works. This is my first offer on this place, and Your job-name, which I immediately noticed and recognized, have motivated me to make my bid to You.
With regards,
Nedeljko Gligorevic
