Inclusion

3 : a relation between two classes that exists when all members of the first are also members of the second Merriam Webster

e.g.

"An object A belongs to a group G by a degree R. R represents the degree of inclusion of A in G."

Yes inclusion works in the more specialised sense of the word above.

Another possibility is association.
