Constructor Detail

POSTaggerFactory

public POSTaggerFactory()

Creates a POSTaggerFactory that provides the default implementation of the resources.

POSTaggerFactory

public POSTaggerFactory(Dictionary ngramDictionary,
                TagDictionary posDictionary)

Creates a POSTaggerFactory. Use this constructor to programmatically create a factory.

Parameters:

ngramDictionary -

posDictionary -

Method Detail

createArtifactSerializersMap

public Map<String,ArtifactSerializer> createArtifactSerializersMap()

Description copied from class: BaseToolFactory

Creates a Map with pairs of keys and ArtifactSerializer. The models implementation should call this method from BaseModel#createArtifactSerializersMap

The base implementation will return a HashMap that should be populated by sub-classes.

Overrides:

createArtifactSerializersMap in class BaseToolFactory

createArtifactMap

public Map<String,Object> createArtifactMap()

Description copied from class: BaseToolFactory

Creates a Map with pairs of keys and objects. The models implementation should call this constructor that creates a model programmatically.

The base implementation will return a HashMap that should be populated by sub-classes.

Overrides:

createArtifactMap in class BaseToolFactory

createTagDictionary

public TagDictionary createTagDictionary(File dictionary)
                                  throws InvalidFormatException,
                                         FileNotFoundException,
                                         IOException

Throws:

InvalidFormatException

FileNotFoundException

IOException

createTagDictionary

public TagDictionary createTagDictionary(InputStream in)
                                  throws InvalidFormatException,
                                         IOException

Throws:

InvalidFormatException

IOException

setTagDictionary

getTagDictionary

public TagDictionary getTagDictionary()

getDictionary

public Dictionary getDictionary()

setDictionary

public void setDictionary(Dictionary ngramDict)

getPOSContextGenerator

public POSContextGenerator getPOSContextGenerator()

getPOSContextGenerator

public POSContextGenerator getPOSContextGenerator(int cacheSize)

getSequenceValidator

public SequenceValidator<String> getSequenceValidator()

validateArtifactMap

public void validateArtifactMap()
                         throws InvalidFormatException

Description copied from class: BaseToolFactory

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.

Specified by:

validateArtifactMap in class BaseToolFactory

Throws:

InvalidFormatException

create

public static POSTaggerFactory create(String subclassName,
                      Dictionary ngramDictionary,
                      TagDictionary posDictionary)
                               throws InvalidFormatException

Throws:

InvalidFormatException

createEmptyTagDictionary
