Semantic Type<br />

A category that defines the real-world meaning of the data and therefore<br />

how applications should interpret that data.<br />

For example, Person is a semantic type that could be assigned to entity<br />

types such as Male, Victim, and Witness. The semantic type allows the<br />

application to understand that each of those entity types are a different way<br />

of depicting people in the real world.<br />

The semantic types are organized into three hierarchies:<br />

• Entity semantic type<br />

• Link semantic type<br />

• Property semantic type<br />

Property Semantic Type, Semantic Matching.<br />

Semantic Type Library<br />

A collection of entity, link, and property semantic types. The purpose is to<br />

share these semantic types. There are two kinds of semantic type library:<br />

the i2 Semantic Type Library, and a Custom Semantic Type Library.<br />
