Method Detail

createArtifactSerializers

protected void createArtifactSerializers(Map<String,ArtifactSerializer> serializers)

Description copied from class: BaseModel

Registers all ArtifactSerializer for their artifact file name extensions. The registered ArtifactSerializer are used to create and serialize resources in the model package. Override this method to register custom ArtifactSerializers. Note: Subclasses should generally invoke super.createArtifactSerializers at the beginning of this method. This method is called during construction.

Overrides:

createArtifactSerializers in class BaseModel

Parameters:

serializers - the key of the map is the file extension used to lookup the ArtifactSerializer.

validateArtifactMap

protected void validateArtifactMap()
                            throws InvalidFormatException

Description copied from class: BaseModel

Validates the parsed artifacts. If something is not valid subclasses should throw an InvalidFormatException. Note: Subclasses should generally invoke super.validateArtifactMap at the beginning of this method.

Overrides:

validateArtifactMap in class BaseModel

Throws:

InvalidFormatException

getPosModel

public opennlp.model.AbstractModel getPosModel()

getTagDictionary

public POSDictionary getTagDictionary()

Retrieves the tag dictionary.

Returns:

tag dictionary or null if not used

getNgramDictionary

public Dictionary getNgramDictionary()

Retrieves the ngram dictionary.

Returns:

ngram dictionary or null if not used
