An alternative direction of research that contrasts with componential analysis is prototype semantics. Sternberg associated the componential subtheory with analytical giftedness. Sternberg's theory comprises three parts&colon; componential, experiential, and practical. Such elements provide a bridge to componential analysis and the initial work of ontologies. The other kinds of analysis are taxonomy analysis, componential analysis, and theme analysis. This approach is called componential analysis, also known as semantic decomposition. He also developed Ralph Linton's Status/Role theory, also applying a structural componential analysis.
