Class Entity

java.lang.Object

it.cnr.isti.hpc.dexter.entity.Entity

All Implemented Interfaces:

Serializable, Comparable<Entity>

public class Entity
extends Object
implements Comparable<Entity>, Serializable

The entity is the core concept on a Entity Linking system. The entity object is described by:

• The id of the entity in the external knowledge base
• The frequency of the entity, i.e. how many times the entity is linked in the knowledge base

If the id of the entity is < 0, than it means it is a disambiguation page - i.e. a page that have different meanings and link to each one of them.
