document: Learning spatial relations using an inductive logic programming system The ability to learn spatial relations is a prerequisite for performing many relevant tasks such as those associated with motion , orientation , navigation , etc. . This paper reports on using an Inductive Logic Programming -LRB- ILP -RRB- system for learning function-free Horn-clause descriptions of spatial knowledge . Its main contribution , however , is to show that an existing relation between two reference systems-the speaker-relative and the absolute-can be automatically learned by an ILP system , given the proper background knowledge and positive examples
