Class Summary

Class	Description
AddClassifierTokenPredictions	This pipe uses a Classifier to label each token (i.e., using 0-th order Markov assumption), then adds the predictions as features to each token.
AddClassifierTokenPredictions.TokenClassifiers	This inner class represents the trained token classifiers.
Array2FeatureVector	Converts a Java array of numerical types to a FeatureVector, where the Alphabet is the data array index wrapped in an Integer object.
AugmentableFeatureVectorAddConjunctions	Add specified conjunctions to each instance.
AugmentableFeatureVectorLogScale	Given an AugmentableFeatureVector, set those values greater than or equal to 1 to log(value)+1.
CharSequence2CharNGrams	Transform a character sequence into a token sequence of character N grams.
CharSequence2TokenSequence	Pipe that tokenizes a character sequence.
CharSequenceArray2TokenSequence	Transform an array of character Sequences into a token sequence.
CharSequenceReplace	Given a string, repeatedly look for matches of the regex, and replace the entire match with the given replacement string.
CharSubsequence	Given a string, return only the portion of the string inside a regex parenthesized group.
Classification2ConfidencePredictingFeatureVector	Pipe features from underlying classifier to the confidence prediction instance list
Csv2Array	Converts a string of comma separated values to an array.
Csv2FeatureVector	Converts a string of the form feature_1:val_1 feature_2:val_2 ...
Directory2FileIterator	Convert a File object representing a directory into a FileIterator which iterates over files in the directory matching a pattern and which extracts a label from each file path to become the target field of the instance.
FeatureSequence2AugmentableFeatureVector	Convert the data field from a feature sequence to an augmentable feature vector.
FeatureSequence2FeatureVector	Convert the data field from a feature sequence to a feature vector.
FeatureValueString2FeatureVector	Unimplemented.
FeatureVectorConjunctions	Include in the FeatureVector conjunctions of all its features.
Filename2CharSequence	Given a filename contained in a string, read in contents of file into a CharSequence.
Input2CharSequence	Pipe that can read from various kinds of text sources (either URI, File, or Reader) into a CharSequence
InstanceListTrimFeaturesByCount	Unimplemented.
IteratingPipe	Converts the iterator in the data field to a PipeOutputAccumulation of the values spanned by the iterator.
IteratorPipe	Unimplemented.
LineGroupString2TokenSequence
MakeAmpersandXMLFriendly	convert & to &amp in tokens of a token sequence
Noop	A pipe that does nothing to the instance fields but which has side effects on the dictionary.
ParallelPipes	Convert an instance to the PipeOutputAccumulator output produced by running the original instance through each of the sub pipes contained in the parallel pipe.
Pipe	The abstract superclass of all Pipes, which transform one data type to another.
PipeOutputArrayList	A PipeOutputAccumulator implemented as an ArrayList.
PrintInput	Print the data field of each instance.
PrintInputAndTarget	Print the data and target fields of each instance.
PrintTokenSequenceFeatures	Print properties of the token sequence in the data field and the corresponding value of any token in a token sequence or feature in a featur sequence in the target field.
SaveDataInSource	Set the source field of each instance to its data field.
SelectiveSGML2TokenSequence	Similar to SGML2TokenSequence, except that only the tags listed in allowedTags are converted to Labels.
SerialPipes	Convert an instance through a sequence of pipes.
SGML2TokenSequence	Converts a string containing simple SGML tags into a dta TokenSequence of words, paired with a target TokenSequence containing the SGML tags in effect for each word.
SimpleTaggerSentence2TokenSequence	Converts an external encoding of a sequence of elements with binary features to a TokenSequence.
SourceLocation2TokenSequence	Read from File or BufferedRead in the data field and produce a TokenSequence.
StringAddNewLineDelimiter	Pipe that can adds special text between lines to explicitly represent line breaks.
Target2FeatureSequence	Convert a token sequence in the target field into a feature sequence in the target field.
Target2Label	Convert object in the target field into a label in the target field.
Target2LabelSequence	convert a token sequence in the target field into a label sequence in the target field.
TargetRememberLastLabel	For each position in the target, remember the last non-background label.
Token2FeatureVector	convert the property list on a token into a feature vector
TokenSequence2FeatureSequence	Convert the token sequence in the data field each instance to a feature sequence.
TokenSequence2FeatureSequenceWithBigrams	Convert the token sequence in the data field of each instance to a feature sequence that preserves bigram information.
TokenSequence2FeatureVectorSequence	Convert the token sequence in the data field of each instance to a feature vector sequence.
TokenSequence2TokenIterator	Convert the token sequence in the data field of each instance to a token iterator
TokenSequenceLowercase	Convert the text in each token in the token sequence in the data field to lower case.
TokenSequenceMatchDataAndTarget	Run a regular expression over the text of each token; replace the text with the substring matching one regex group; create a target TokenSequence from the text matching another regex group.
TokenSequenceNGrams	Convert the token sequence in the data field to a token sequence of ngrams.
TokenSequenceParseFeatureString
TokenSequenceRemoveNonAlpha	Remove tokens that contain non-alphabetic characters.
TokenSequenceRemoveStopwords	Remove tokens from the token sequence in the data field whose text is in the stopword list.
