- 9 abstract "Data on the Semantic Web is ordered, for instance, through orderingsover literals (e.g., age, heights, location, rating etc), resources(e.g., popularity) or triples (e.g., provenance, confidence, time-stamps).Recently, orderings have been established as first class citizensin an extended SPARQL algebra, with an efficient calculus for finding, e.g.,top-k answers. In this paper we advocate a similar initiative for thesemantic (or reasoning) part of such querying: given an expressiveknowledge base with orderings, can we make use of these orderings toefficiently reason over large datasets where top-k answers are required.The basic idea is to define the notion of a top-k closure, which isa subset of the full semantic closure sufficient to answertop-k queries. We argue that this top-k closure can be efficiently calculated by applying top-k joins needed when applying entailment rules of the standard calculus.This paper introduces the top-k reasoning problem, and advocates a potential solution.
