Web20 de jan. de 2024 · Ontology Alignment: Algorithms and Evaluation. Ontology matching is a solution to the semantic heterogeneity problem between different ontologies or knowledge graphs. It takes ontologies as input and determines as output an alignment, that is, a set of correspondences between the semantically related entities of those ontologies. Web1 de jan. de 2024 · Reasoning is critical to ensure the logical consistency of ontologies, and to compute inferred knowledge from an ontology. It has been shown both theoretically and empirically that, despite decades of intensive work on optimising ontology reasoning algorithms, performing core reasoning tasks on large and expressive ontologies is time …
