github.com/michielbuddingh/nilsimsa (go): Package nilsimsa implements the nilsimsa fuzzy hash by cmeclax.  In summary, nilsimsa is a trigram frequency table, with a bit depth of 1 bit.  Table positions are zero if the frequency of a specific hash value is lower than average, and 1 if it is higher than average.  Nilsimsa codes of two texts can be compared; similar texts will have very similar frequency distributions.
