New logic ELbotpreceq extends DL-Lite for graph query languages

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced ELbotpreceq, a new description logic that extends DL-Lite and supports reasoning in NL. This logic is designed to be rewritable into graph query languages, addressing the limitations of existing DL-Lite systems which are restricted to first-order queries. ELbotpreceq incorporates a stratification mechanism to manage conjunction and recursion, enabling it to express many ELI and DL-Lite ontologies while maintaining NL upper bounds. AI

IMPACT Extends expressive power for ontology-mediated query answering, potentially enabling more complex graph data querying.

    A Horn extension of DL-Lite with NL data complexity

    The literature on ontology-mediated query answering (OMQA) has been shaped by two key results: first-order rewritability for DL-Lite, and PTime-hardness of data complexity for essentially every description logic beyond it. This has effectively positioned DL-Lite as the only pract…
