What do the m1_trigram and m2_trigram scores represent?

[DivyanshuSheth]

Hi, I had a question about what the m1_trigram and m2_trigram scores represent in the trigrams_cleaned.csv file in the v2/data directory, as they are given corresponding to each word, not trigrams? Also, for a lot of cases, the m1 and m2 values are the same, but they're different for a few cases -- could you please let me know how these values were derived? I really appreciate your work and thank you for your help!
