A semantics is proposed called Kernel Set Subsumption (KSS) that generalises the well-known inference method of Bottom Generalisation by deriving hypotheses with more than one clause. A corresponding proof procedure is presented, called HAIL, which extends the ALP procedure of Kakas and Mancarella and integrates it within a generalisation of Muggleton’s widely-used ILP system Progol5. HAIL is shown to overcome some of the limitations of Progol5 — including a previously unsuspected incompleteness — and to enlarge the class of learning problems soluble in practice.}, abstract-url={http://www.cs.bris.ac.uk/Publications/pub_master.jsp?id=2000718}, url={http://www.cs.bris.ac.uk/Publications/Papers/2000718.pdf}, keyword={Artificial Intelligence,Logic Programming,Machine Learning}, pubtype={116} }
