In this work, we present a novel web ontology of cultural conceptualizations that is based on the Cultural Linguistics framework developed by Farzad Sharifian. This theoretical-analytical framework explores the relationship between Cognition, Culture and Language (CCL), focusing on three components, i.e. cultural schemas, categories and metaphors, through which linguistic expressions and their cognitive underpinnings are analysed. The CCL ontology reuses the DOLCE (DOLCE+DnS Ultralite) foundational ontology, selected for its cognitive emphasis and extends it with domain-specific concepts and relationships. Potential use in comparative cultural studies and cross-cultural educational contexts is demonstrated through a set of use cases constructed from published research on political discourse in Ghana and China and the comprehension of Australian Aboriginal English narratives.
