    $\begingroup$ What paper is this? The answer to your question is probably in the paper that mentions "ontology-based" and without further context it is hard to help here... Ontologies are simply logical theories, therefore, you can consider any (typically first order) logical theory as an example. "Ontology-based" can then mean anything that is done together with ontologies. A common usage is in ontology based data access, which is nothing else but querying data sources (say databases) with the help of ontological rules. $\endgroup$
