Constructor Detail

TKSVMlightBooleanOutcomeDataWriter

public TKSVMlightBooleanOutcomeDataWriter(File outputDirectory)
                                   throws IOException

Constructor for the Tree Kernel SVM Light data writer.

Parameters:

outputDirectory - The directory the data/files should be written within.

Throws:

IOException

Method Detail

createString

public static String createString(TreeFeatureVector features)
                           throws org.cleartk.classifier.CleartkProcessingException

creates and formats a string (without the outcome) for a specific feature vector. Public so that the one versus all data writer may use it, not for casual use.

Parameters:

features - The featuers to write into a string format.

Returns:

The string that represents the features in a format that tk_svm_classify can utilize.

Throws:

org.cleartk.classifier.CleartkProcessingException

writeEncoded

public void writeEncoded(TreeFeatureVector features,
                         Boolean outcome)
                  throws org.cleartk.classifier.CleartkProcessingException

Write a line representing the feature vector with the appropriate outcome to be used by the tk_svm_classify command.

Specified by:

writeEncoded in class org.cleartk.classifier.jar.DataWriter_ImplBase<TKSVMlightBooleanOutcomeClassifierBuilder,TreeFeatureVector,Boolean,Boolean>

Parameters:

features - The feature vector to be written.

outcome - The correct classification for that feature vector.

Throws:

org.cleartk.classifier.CleartkProcessingException

newClassifierBuilder

protected TKSVMlightBooleanOutcomeClassifierBuilder newClassifierBuilder()

Specified by:

newClassifierBuilder in class org.cleartk.classifier.jar.DirectoryDataWriter<TKSVMlightBooleanOutcomeClassifierBuilder,org.cleartk.classifier.Classifier<Boolean>>
