Invited research visit in Japan (June-August 2011): Michaël Thomazo has been invited to Ken Kaneiwa laboratory at Iwate University (Japan), thanks to a grant from the Japan Society for the Promotion of Science (JSPS). A comparison between the existential rule framework studied in GraphIK and the predicate/meta-predicate hierarchies framework as studied by Ken Kaneiwa in [59] has been conducted. They have been shown mutually reducible to each other, allowing to enrich existential rules with meta-predicates and to discover new decidable classes for query answering with (meta-)predicate hierarchies. Article in preparation.
