Currently the insights() does not incorporate the rank of results returned by Moss.
Quote from How to Read the Resuls

False positives are possible with Moss, as programs may legitimately share code (e.g., two programs making use of the same public-domain library). The higher-ranked pairs are more likely to be the result of plagiarism than the lower-ranked pairs. The recommended strategy is to start with the highest-ranked pair and work down the list until one finds that a large fraction of the reported matches are false positives.

A rank based algorithm should be added to find the potential distributor-culprit relationships

I am facing some error while testing it locally. What could be the possible reason ?

The statement

diff_results = self.__getLineNumbers(element.a.get('href'))

gets executed 2 times inside the loop in def __extractInfo(self, url): method.

The problem is both times the link is same, so it should run only 1 time(i.e that is one iteration of inner loop is redundant)
