实体种类表、关系种类表、后选关系表

实体是作为一个主体或一个客体存在的东西,实际上或潜在地,具体地或抽象地,物理上或不是,代词(你,我,他)也是一种实体形式。 根据ACE2008,实体可以分为五类:人,组织,地缘政治实体,位置和设施。 我们标记了这些实体类型,如表2所示。
An entity is something that exists as itself, as a subject or as an object, actually or potentially, concretely or abstractly, physically or not, the pronoun (you, me, he) is also a form of entity. According to ACE2008, entities can be classified into five categories: Person, Organization, Geo-political entity, Location and Facility. We label these entity types as shown in Table 2.

两个实体之间的关系可以分为七类:物理,部分整体,个人社会,ORG-Af fi lation,Agent-Artifact,Gen-Affliation和NA.3我们将这些关系类型标记为表3所示。
The relations between two entities can be classified into seven categories: Physical, Part-whole, Personal-Social, ORG-Affiliation, Agent-Artifact, Gen-Affiliation and NA.3 We label these relation types as shown in Table 3.

表4显示了双实体对需要满足的条件,以在它们之间形成某种类型的关系。
Table 4 shows the conditions that a two-entity pair need to meet to form a certain type relation between them.
