| Abstract : | In this paper, we address the problem of answering (unions of) conjunctive queries on Aboxes. We propose a backward-chaining query evaluation based on query expansion. Expanding a query consists of determining all the ways of deriving it from atoms built on some distinguished predicates. 1, |
