VertexJaccardSimilarity[g,u,v]
gives the Jaccard similarity between vertices u and v of the graph g.
VertexJaccardSimilarity[{vw,…},…]
uses rules vw to specify the graph g.


VertexJaccardSimilarity
VertexJaccardSimilarity[g,u,v]
gives the Jaccard similarity between vertices u and v of the graph g.
VertexJaccardSimilarity[{vw,…},…]
uses rules vw to specify the graph g.
Details

- The vertex Jaccard similarity is also known as Jaccard index and Jaccard similarity coefficient.
- The vertex Jaccard similarity between u and v is the number of common neighbors of u and v divided by the number of vertices that are neighbors of u or v.
- VertexJaccardSimilarity works with undirected graphs, directed graphs, multigraphs, and mixed graphs.

Properties & Relations (3)
Use JaccardDissimilarity to compute the Jaccard similarity of a graph:
The Jaccard similarity between two vertices is equal to zero if one of them has degree zero:
The Jaccard similarity between two vertices is equal to 1 if they have the same neighbors:
