Abstract / Description of output

In this work we present a novel graph-based approach for studying the tractability of query answering over ontologies expressed by means of tuple-generating dependencies (TGDs). We do this by defining a new class of TGDs that subsumes all the other known classes that enjoy a particularly desirable property called first-order rewritability of query answering.
