KBpedia

KBpedia is a comprehensive knowledge structure for promoting data interoperability and knowledge-based artificial intelligence, or KBAI. The KBpedia knowledge structure combines seven 'core' public knowledge bases — Wikipedia, Wikidata, schema.org, DBpedia, GeoNames, OpenCyc, and UMBEL — into an integrated whole. KBpedia's upper structure, or knowledge graph, is the KBpedia Knowledge Ontology. We base KKO on the universal categories and knowledge representation theories of the great 19th century American logician, polymath and scientist, Charles Sanders Peirce.

Cultural-ON

"L’ontologia Cultural-ON, realizzata nell’ambito di una Convenzione tra il MIBACT e l’Istituto di Scienze e Tecnologie della Cognizione del Consiglio Nazionale delle Ricerche (ISTC-CNR), ha lo scopo di modellare i dati che caratterizzano gli istituti e i luoghi della cultura, come ad esempio i dati sugli enti o sulle persone che hanno un determinato ruolo sugli istituti e luoghi della cultura, le sedi fisiche dei luoghi, i contatti, eventuali materiali multimediali che descrivono un istituto e luogo della cultura e ogni altra informazione utile al pubblico per poter accedere all’istituto

"The ontology aims at modelling the data on cultural institutes or sites such as data regarding the agents that play a specific role on cultural institutes or sites, the sites themselves, the contact points, all multimedia files which describe the cultural institute or site and any other information useful to the public in order to access the institute or site. Moreover, the ontology represents events that can take place in specific cultural institutes or sites. The following figure illustrates some of the core elements of the ontology.

Semantic Web Rule Language

"This document contains a proposal for a Semantic Web Rule Language (SWRL) based on a combination of the OWL DL and OWL Lite sublanguages of the OWL Web Ontology Language with the Unary/Binary Datalog RuleML sublanguages of the Rule Markup Language. SWRL includes a high-level abstract syntax for Horn-like rules in both the OWL DL and OWL Lite sublanguages of OWL. A model-theoretic semantics is given to provide the formal meaning for OWL ontologies including rules written in this abstract syntax.
