Efficiently Enumerating Answers to Ontology-Mediated Queries
Summary: Defines two partial-answer notions for OMQs (guarded TGDs / ELI) that account for existentially generated nulls. Proves enumeration of complete and partial answers with linear-time preprocessing and constant delay for OMQs that are acyclic and free-connex acyclic, with matching lower bounds and acyclicity-based tractability borders.
