Abstract: In Inductive Logic Programming (ILP), several techniques have been introduced to improve the eciency of query execution. One such technique is query pack execution. A set of queries with a common pre x, as it is generated by the re nement operator of a typical ILP system, can be executed faster after it is converted into a tree structure called a query pack. Query transformations, on the other hand, improve the eciency of executing a single query by transforming it into a di erent form ... (Update)
