Title
OPINO - OPinions and INterpretations Ontology
Description
OPINO is a DOLCE+DnS Ultralite-based ontology design pattern for representing scholarly opinions and interpretations in cultural heritage knowledge graphs. An Opinion is an information object that expresses a Predicative Content, a collection of Predications (reified claims). Each Predication is a situation with a subject, a predicate and an object, read through a claim-type Description and, where relevant, holding at a time. Epistemic status, confidence and certainty attach to each Predication, so the claims of an Opinion are qualified individually, or to the Predicative Content as a default for its members; the subclasses Assertion, Belief, Hypothesis and Conjecture classify Predications by status, and Reference marks a claim reported from another source. Argumentative relations (supports, evidences, conflicts with, negates, concludes that) link Predications, and hasAuthor shortcuts the provenance path from an Opinion to its author. Informed by the DOLCE epistemic layer (Masolo et al.) and the MITE observation ontology (Sanfilippo et al.), and aligned with HiCO, PROV-O, RDF reification and CRMinf. Developed within the INFINITY project (Horizon Europe, grant agreement no. 101233051). Competency questions with SPARQL queries and a worked example are in the documentation linked from dcterms:source.
