Inductive Logic Programming (ILP) algorithms are frequently used to data mine multi-relational databases. However, in many ILP algorithms the use of primary key constraints is limited. We show how primary key constraints can be incorporated in a downward refinement operator. This refinement operator is proved to be finite, complete, proper and therefore ideal for clausal languages defined by pr...
