(7) implies that features in the creation model are also separable; Moreover, the conditioning part h k (e, m t ) : e ∈ E t } , also a binary function, only depends on the function values of the set of link features {g 1k (e, m t ) : e ∈ E t } (for some k).
once {g 1k (e, m t ) : e ∈ E t } and C are known, we can compute h i (E t , m t , C) without actually comparing m t with any entity in E t .
