Method Details
-
getPosModel
Deprecated.usegetPosSequenceModel()
instead. This method will be removed soon. Only required for Parser 1.5.x backward compatibility. Newer models don't need this anymore. -
getPosSequenceModel
- Returns:
- Retrieves a
SequenceClassificationModel
.
-
getFactory
- Returns:
- Retrieves the active
POSTaggerFactory
.
-
getArtifactSerializerClass
Description copied from interface:SerializableArtifact
Retrieves the class which can serialize and recreate this artifact.Note: The serializer class must have a
public zero argument constructor
or an exception is thrown during model serialization/loading.- Specified by:
getArtifactSerializerClass
in interfaceSerializableArtifact
- Returns:
- The corresponding
ArtifactSerializer
class.
-
hashCode
public int hashCode() -
equals
-
getPosSequenceModel()
instead.
