Towards Healthy Aging through Semantic Enrichment

This paper introduces two interoperable ontologies-SOLO (Solitude Ontology) and GERO (Gerotranscendence Ontology)-developed to formalize key psychological constructs relevant to healthy aging. Grounded in the Behavioral Change Intervention Ontology, the ontologies clarify distinctions between terms such as solitude, loneliness, self-transcendence, and gerotranscendence, and encode their realization conditions across the lifespan. By integrating validated psychometric instruments and supporting structured responses to competency questions, the ontologies enable semantic reasoning, cross-disciplinary data integration, and development of ontology-driven tools for aging research and intervention design.
