Method Detail

canResolve

public boolean canResolve(MentionContext mention)

Description copied from interface: Resolver

Returns true if this resolver is able to resolve the referring expression of the same type as the specified mention.

Parameters:

mention - The mention being considered for resolution.

Returns:

true if the resolver handles this type of referring expression, false otherwise.

excluded

public boolean excluded(MentionContext mention,
                        DiscourseEntity entity)

Description copied from class: AbstractResolver

Excludes entities which you are not compatible with the entity under consideration. The default implementation excludes entities whose last extent contains the extent under consideration. This prevents possessive pronouns from referring to the noun phrases they modify and other undesirable things.

Parameters:

mention - The mention which is being considered as referential.

entity - The entity to which the mention is to be resolved.

Returns:

true if the entity should be excluded, false otherwise.
