本体论的主要目标之一是恰当地表示混乱世界的底层概念结构，尽可能地反映现实。本体构建工具应该被设计成帮助开发人员创建好的本体。然而，他们中很少有人能充分处理角色。不用说，这个世界充满了角色（例如，妻子、老师、总统、燃料、食物、产品、产量、身高）虽然对角色的理论研究已经很广泛，但我们还没有一个全面的、可用的理论。我们的团队已经构建了一个本体开发工具，称为HOZO，它具有处理角色的能力。然而，尽管Hozo允许用户比其他现有工具更好地表示角色，但其基本理论基础仍然不清楚，并且在如何处理角色的一般性方面还有一些改进的空间。在本文中，作为Hozo角色框架的扩展，我们提出了一个根据上下文依赖性组织角色概念的框架。我们还专注于澄清的角色属性和要求的角色模型和从Hozo的本体建设经验的反馈。角色的计算模型的建立有助于建立良好的本体，因为这样的理论将提供有用的指导方针，处理与角色相关的视图相关和上下文相关的区别。
One of the major goals of ontology is to represent properly the underlying conceptual structure of the messy world reflecting the reality as much as possible. Ontology building tools should be designed to help developers create good ontologies. However, few of them can deal with roles adequately. Needless to say, the world is full of roles (e.g., wife, teacher, president, fuel, food, product, output, height) although there has been extensive theoretical research on roles, we do not yet have a comprehensive and usable theory yet. Our group has already constructed an ontology-development tool known as Hozo which has the ability to deal with roles. However, although Hozo allows users to represent roles better than other existing tools, the underlying theoretical foundations are still unclear and there is some room for improvement concerning the generality of how to deal with roles. In this paper, as an extension of the Hozo framework for roles, we present a framework for organizing role concepts according to their context dependencies. We also focus on the clarification of role properties and requirements on the model of roles and on the feedback obtained from Hozo-based ontology building experiences. Establishment of a computational model of roles contributes to building good ontologies because such a theory would provide useful guidelines for dealing with view-related and context-dependent distinctions related to roles.
