Abstract:Abstract.A common approach for reasoning is to compute the deductive closure of an ontology using the rules specified and to work on the closure at query time. This approach reduces the run time complexity but increases the space requirements. The main reason of this increase is the type and subclass statements in the ontology. Type statements show a significant percentage in most ontologies. Since subclass is a transitive property, derivation of other statements, in particular type statements relying on it, g… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
