public TKSVMlightStringOutcomeClassifierBuilder()

Method Detail

getTrainingDataFile

public File getTrainingDataFile(File dir)

Specified by:

getTrainingDataFile in class org.cleartk.classifier.jar.EncodingJarClassifierBuilder<TKSVMlightStringOutcomeClassifier,TreeFeatureVector,String,Integer>

Parameters:

dir - The directory that contains the all false training data.

getTrainingDataFile

public File getTrainingDataFile(File dir,
                                int label)

Get the training data file for a specific label.

Parameters:

dir - The directory to keep the training data.

label - The integer number that represents an index for a particular label.

Returns:

The file of the training data to be used to train the model.

trainClassifier

public void trainClassifier(File dir,
                            String... args)
                     throws Exception

Train the OVASVMTK classifier.

Specified by:

trainClassifier in class org.cleartk.classifier.jar.JarClassifierBuilder<TKSVMlightStringOutcomeClassifier>

Parameters:

dir - The directory where the training data has been written.

args - The arguments to be used by the tk_svm_classify command. Note: -t 5 is used to specify the use of Tree Kernels.

Throws:

Exception

packageClassifier

protected void packageClassifier(File dir,
                                 JarOutputStream modelStream)
                          throws IOException

Package the classifier into a jar file.

Overrides:

packageClassifier in class org.cleartk.classifier.jar.EncodingJarClassifierBuilder<TKSVMlightStringOutcomeClassifier,TreeFeatureVector,String,Integer>

Throws:

IOException

unpackageClassifier

protected void unpackageClassifier(JarInputStream modelStream)
                            throws IOException

Unpackage the classifier out of a JarInputStream.

Overrides:

unpackageClassifier in class org.cleartk.classifier.jar.EncodingJarClassifierBuilder<TKSVMlightStringOutcomeClassifier,TreeFeatureVector,String,Integer>

Throws:

IOException

newClassifier

protected TKSVMlightStringOutcomeClassifier newClassifier()

Create a OVATKSVMlightClassifier.

Specified by:

newClassifier in class org.cleartk.classifier.jar.JarClassifierBuilder<TKSVMlightStringOutcomeClassifier>
