I have some question concern similarity measureSuppose that we have a matrix M where M(i,j) is the similarity measure between user i and user j .Each user is characterised by : id-user | country | id-artist | id-track For this I choose to use Jaccard similarity metric.Jaccard is determined to compute similarity between users based on the tracks that they listened.My question is : is it possible to take account both id-track and id-artist to measure the similarity between users?Thank you
