Wikidata用多轴分类打破单一层级，让知识图谱更灵活可扩展。
A Multi-Axial Mindset for Ontology Design Lessons from Wikidata's Polyhierarchical Structure
- 允许同一实体同时归属多个分类维度，突破传统单一层级限制。
- 支持协作式知识构建，结构模块化且易于迭代更新。
- 适合动态演化、多人协作的知识图谱项目参考设计。
传统本体设计强调互斥且穷尽的顶层区分，如持续体与事件、抽象与具体、类型与实例，构建统一的单层分类体系。Wikidata则不强制单一基础分类体系，而是允许多个分类轴线在共享根类 'entity' 下并行存在。本文分析了Wikidata多层级、多轴向设计的结构影响，其架构支持可扩展、模块化的本体构建方式，特别适用于协作式、持续演进的知识图谱。
原文摘要 · Abstract (English)
Traditional ontology design emphasizes disjoint and exhaustive top-level distinctions such as continuant vs. occurrent, abstract vs. concrete, or type vs. instance. These distinctions are used to structure unified hierarchies where every entity is classified under a single upper-level category. Wikidata, by contrast, does not enforce a singular foundational taxonomy. Instead, it accommodates multiple classification axes simultaneously under the shared root class entity. This paper analyzes the structural implications of Wikidata's polyhierarchical and multi-axial design. The Wikidata architecture enables a scalable and modular approach to ontology construction, especially suited to collaborative and evolving knowledge graphs.
