What is negation?

General description

For every negation, annotate a modifier relation

For every negation signal, at least one modifier relation must also be annotated, relating it to the associated condition.

For every negation, select a value

Each Negation signal that is annotated will be assigned a value from the enumeration: {absent, uncertain}.

Annotate the entire phrase

Entities other than conditions are not negated

Only conditions will be negated. If a phrase describes the existence of something other than a condition, then it will not be annotated.

Conditions that are already expressed in the negative

Negation is not about marking conditions that are already negatives
