BaseRuleFactory

public BaseRuleFactory()

Method Detail

apply

public List<Rule> apply(Annotation annotation)

Specified by:

apply in interface com.google.common.base.Function<Annotation,List<Rule>>

create

public List<Rule> create(Annotation annotation)

Create base rules from the supplied annotation. There may be multiple if different argument constraints may be specified.

Parameters:

annotation - seed for base rules

Returns:

base rules

validate

protected boolean validate(List<OntologicalFormArgument> arguments)

Returns true if the arguments satisfy the minimum requirements for a base rule.

Parameters:

arguments - arguments to validate

Returns:

create

public List<Rule> create(Annotation annotation,
                         RelationExtraction extraction)

Create base rules from the supplied annotation and extraction. There may be no base rules if the ontological relation cannot be mapped from the supplied extraction.

Parameters:

annotation - seed for base rules

extraction - to apply base rules

Returns:

list of base rules

filter

public List<AnnotatedSentence> filter(List<AnnotatedSentence> annotateds)

isLearnable

public boolean isLearnable(Annotation annotation)

createOntologicalForms

protected List<OntologicalForm> createOntologicalForms(Annotation annotation,
                                                       RelationExtraction extraction)

Used in base rule creation.

Parameters:
