How weighted Node Similarity scores are calculated?

Hi guys,

I just wanna know how Weighted Jaccard Similarity calculate the scores. The documentation is not so clear to me.

For example I have graph as followed:

Both scores are 0.11111

what is the formula for calculating the weighted similarity score?

Thanks!

Node Similarity is calculated based Jaccard Similarity (common neighbor nodes), and weighted node similarity uses weighted Jaccard:
