I think what would improve the relevency the most is a better data set. The CPAN data set was generated from the 'prereq' keys in the Module::CPANTS::asHash module, and this is only a rough representatation of the linking structure. It would have been better to download all the CPAN modules and do source code analysis directly on them.
