Multiple Ontologies

Ontologies are computational artifacts that model consensual aspects of reality. In distributed contexts, applications often need to utilize information from several distinct ontologies. In order to integrate multiple ontologies, entities modeled in each ontology must be matched through an ontology alignment. However, imperfect alignments may introduce inconsistencies. One kind of inconsistency, which is often introduced, is the violation of the conservativity principle, that states that the alignment should not introduce new subsumption relations between entities from the same source ontology. We propose a two-step quadratic-time algorithm for automatically correcting such violations, and evaluate it against datasets from the Ontology Alignment Evaluation Initiative 2019, comparing the results to a state-of-the-art approach. The proposed algorithm was significantly faster and less aggressive; that is, it performed fewer modifications over the original alignment when compared to the state-of-the-art algorithm.

Critical Reflections

There is a human fundamental need to know who we are and where we come from. In an age when myths, legends and family memories are starting to fade or become obsolete, science is brought in to fill the gaps and answer these questions. This article introduces a special theme section dedicated to critical reflections on the relationship between the disciplines of archaeology and archaeogenetics. It gives a summary of the ‘Can science accommodate multiple ontologies? The genetics revolution and archaeological theory’ workshop held in Cambridge 2018, followed by an introduction of the papers in this theme section. Lastly, I evaluate archaeogenetic narratives in terms of their target audience, knowledge obtained (or not) and future directions.
