IsAResolver
public IsAResolver(String projectName,
ResolverMode m)
throws IOException
- Throws:

NonReferentialResolver nrr)
throws IOException
- Throws:
IOException
canResolve
public boolean canResolve(MentionContext ec)
- 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:
ec
- The mention being considered for resolution.
- Returns:
- true if the resolver handles this type of referring
expression, false otherwise.
excluded
protected boolean excluded(MentionContext ec,
DiscourseEntity de)
- 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.
- Overrides:
excluded
in class MaxentResolver
- Parameters:
ec
- The mention which is being considered as referential.de
- The entity to which the mention is to be resolved.
- Returns:
- true if the entity should be excluded, false otherwise.
outOfRange
protected boolean outOfRange(MentionContext ec,
DiscourseEntity de)
- Description copied from class:
AbstractResolver
- Determines if the specified entity is too far from the specified mention to be resolved to it.
Once an entity has been determined to be out of range subsequent entities are not considered.
To skip intermediate entities @see excluded.
- Overrides:
outOfRange
in class AbstractResolver
- Parameters:
ec
- The mention which is being considered.de
- The entity to which the mention is to be resolved.
- Returns:
- true is the entity is in range of the mention, false otherwise.
defaultReferent
protected boolean defaultReferent(DiscourseEntity de)
- Description copied from class:
MaxentResolver
- Returns whether the specified entity satisfies the criteria for being a default referent.
This criteria is used to perform sample selection on the training data and to select a single
non-referent entity. Typically the criteria is a heuristic for a likely referent.
- Overrides:
defaultReferent
in class MaxentResolver
- Parameters:
de
- The discourse entity being considered for non-reference.
- Returns:
- True if the entity should be used as a default referent, false otherwise.
getFeatures
protected List<String> getFeatures(MentionContext mention,
DiscourseEntity entity)
- Description copied from class:
MaxentResolver
- Returns a list of features for deciding whether the specified mention refers to the specified discourse entity.
- Overrides:
getFeatures
in class MaxentResolver
- Parameters:
mention
- the mention being considers as possibly referential.entity
- The discourse entity with which the mention is being considered referential.
- Returns:
- a list of features used to predict reference between the specified mention and entity.
