Horn-ALCHI queries can be rewritten into GQL, researchers find

By PulseAugur Editorial · [1 sources] ·

Researchers have identified a general condition for rewriting atomic queries in Horn-ALCHI, an expressive Description Logic, into GQL (Graph Query Language). This is significant because Horn-ALCHI is not typically first-order rewritable, but GQL is a new ISO standard query language that extends first-order logic with controlled recursion. The proposed method uses a novel formalism called DL automata, which captures the semantics of these queries. By identifying a class of DL automata that can be rewritten into UC2RPQs (a fragment of GQL), the research provides a broad set of Horn-ALCHI OMQs that are compatible with GQL. AI

IMPACT This research could enable more expressive querying of knowledge graphs and ontologies, potentially impacting how AI systems interact with structured data.

    A General Sufficient Condition for Rewriting Horn-ALCHI Atomic Queries into GQL

    The emergence of the ISO standard GQL introduces a powerful query language extending first-order logic with controlled recursion, raising the question of its applicability to evaluation of ontology-mediated queries (OMQs). We focus on OMQs consisting of atomic queries over ontolo…
