This paper explores the ontological space of group well being, proposing a framework for representing collective welfare, group functions, and long term contributions within an ontology engineering context. Traditional well being theories focus on individual states, often relying on hedonistic, desire satisfaction, or objective list models. Such approaches struggle to account for cases where individual sacrifices contribute to broader social progress, a critical challenge in modeling group flourishing. To address this, the paper refines and extends the Counterfactual Account (CT) of well being, which evaluates goodness of an event by comparing an individual's actual well being with a hypothetical counterpart in a nearby possible world. While useful, this framework is insufficient for group level ontologies, where well being depends on functional persistence, institutional roles, and historical impact rather than immediate individual outcomes. Drawing on Basic Formal Ontology (BFO), the paper introduces a model in which group flourishing is evaluated in terms of group functional, where members bear roles and exhibit persistence conditions akin to biological systems or designed artifacts. This approach enables semantic interoperability for modeling longitudinal social contributions, allowing for structured reasoning about group welfare, social institutions, and group flourishing over time.

本研究探讨群体福祉的本体论空间，提出了一个在本体工程背景下表示集体福利、群体功能和长期贡献的框架。通过改进和扩展反事实福祉理论，论文提供了一种模型评估群体兴盛，强调群体的功能性和历史影响，从而推动了对群体福利和社会机构的结构化推理。
