Researchers have developed new methods for fitting Horn Description Logic (DL) ontologies to ABox and query examples. The study focuses on EL and ELI DLs, extending previous work on ALC and ALCI, and considers atomic queries, conjunctive queries, and their unions. The findings include characterizations based on simulations, decision procedures, and complexity analyses, with fitting problems for AQs being PTime for both EL and ELI, and more complex for rooted CQs and UCQs.
