Algebras of Ontology Alignment Relations [PDF]

open access: yes, 2008
Correspondences in ontology alignments relate two ontology entities with a relation. Typical relations are equivalence or subsumption. However, different systems may need different kinds of relations. We propose to use the concepts of algebra of relations in order to express the relations between ontology entities in a general way. We show the benefits

OntoPharma: ontology based clinical decision support system to reduce medication prescribing errors

open access: yesBMC Medical Informatics and Decision Making, 2022
Background Clinical decision support systems (CDSS) have been shown to reduce medication errors. However, they are underused because of different challenges. One approach to improve CDSS is to use ontologies instead of relational databases.

Ontology-based data access with databases: a short course [PDF]

open access: yes, 2013
Ontology-based data access (OBDA) is regarded as a key ingredient of the new generation of information systems. In the OBDA paradigm, an ontology defines a high-level global schema of (already existing) data sources and provides a vocabulary for user ...
