Refining non-taxonomic relation labels with external structured data to support ontology learning

Albert Weichselbraun, Gerhard Wohlgenannt, Arno Scharl
2010 Data & Knowledge Engineering  
This paper presents a method to integrate external knowledge sources such as DBpedia and OpenCyc into an ontology learning system that automatically suggests labels for unknown relations in domain ontologies  ...  It composes a knowledge base which consists of (i) verb centroids for known relations between domain concepts, (ii) mappings between concept pairs and the types of known relations, and (iii) ontological  ...  of External Knowledge Experts define the set of relation labels in a meta ontology to describe the relations used in the domain ontology.  ...

Extraction of common conceptual components from multiple ontologies [article]

Luigi Asprino, Valentina Anita Carriero, Valentina Presutti
2021 arXiv   pre-print
The method is applied to two corpora of ontologies in the Cultural Heritage and Conference domain, respectively.  ...  The results, which show good quality, are evaluated by manual inspection and by correlation with datasets and tool performance from the ontology alignment evaluation initiative.  ...  The catalogue classifies the ontologies according to the conceptual components they implement. We show its potential by testing and evaluating it on two corpora in the CH and Conference domains.  ...
