"什么蔬菜可以跟牛肉一起吃?" 。语义分类在问答中经常被用来构造问答模版。在众多过往的upper ontology中,有没有简洁实用的解决方案呢?

schema.org又是如何呢,下面是一个简单梳理

  • 人物
    • so:Person
  • 机构
    • so:Organization: Corporation, EducationalOrganization, GovernmentOrganization, LocalBusiness, MedicalOrganization, PerformingGroup, SportsOrganization
  • 事物
    • so:CreativeWork -- 抽象事物
    • so:Product -- 实体事物
  • 地点
    • so:Place -- POI为主,也包括行政区划
  • 事件
    • so:Action -- 用户行为
    • so:Event -- 公众活动 Things to do
  • so:Intangible --- 这是一个大杂烩
    • so:Enumeration, so:StructuredValue
    • so:Order, so:Rating, so:Reservation, so:Role, so:Service
  • so:DataType: Boolean, DateTime, Number, Text

关于分类,实体,属性的关系

https://www.w3.org/TR/owl-ref/#Restriction A property restriction is a special kind of class description. It describes an anonymous class, namely a class of all individuals that satisfy the restriction. 基于集合论, 实体为individual, 概念为class, 具有相同属性/特性的实体自然就形成一个集合,不论是否命名。 马车就是马拉的车。 https://en.wikipedia.org/wiki/Taxonomy_(biology) Taxonomy (from Ancient Greek: τάξις taxis, "arrangement", and -νομία -nomia, "method"[1]) is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. 生物学分类就是典型例子。
