Ochiai/Cosine similarity

[roman-bushuiev]

Hi! If I were to implement the querying by Ochiai/Cosine similarity measure (as described by equation 48 here), would you be interested in merging it? I will probably implement it in my fork anyways. :))

Hi Roman, that might certainly be a nice addition. I never added it because we are not using it in ChEMBL but yep, it sounds useful :)
