This documentation describes the entities and relationships that i2 TextChart software can extract from text documents.

Entities
Entities are the named items that i2 TextChart can find in a document. The context of the document is the only vehicle for determining any associated knowledge. Real-world knowledge (or externally encoded knowledge) does not determine associated knowledge with these entities.
No-output entities
No-output entities are entities that i2 TextChart extracts, but whose output it suppresses.
Relationships
In i2 TextChart, relationships are binary connections between entities found in a single document. TextChart defines relationships in terms of predicate-subject-object (PSO) statements.
Sentiment analysis
During extraction, i2 TextChart provides sentiment analysis at the entity and the document level to provide a detailed representation of the sentiment of the text.
