Method Details [hide private]

__init__(self, *args)
(Constructor)

source code 

In order to initialize a language-specific feature generator, the language needs to be instantiatied as a class variable

Parameters:
  • lang - the language code of the language that the feature generator is capable of
Overrides: object.__init__
(inherited documentation)

add_features_batch(self, parallelsentences)

source code 

Abstract method to be overriden by the particular subclassed feature generator. It allows the generation of features over many parallelsentences. It is a flexible solution when feature generation doesn't take place item to item (see SAX parsing) but a whole list of parallel sentences needs to be implemented at once. In this case, feature generator may optimize better when the whole dataset is given.

Parameters:
  • parallelsentences - The parallel sentences to be be augmented
Returns: list(sentence.parallelsentence.ParallelSentence)
The given list of ParallelSentence which are now augmented with features generated from the current featuregenerator
Overrides: featuregenerator.FeatureGenerator.add_features_batch
(inherited documentation)

get_features_simplesentence(self, simplesentence, parallelsentence)

source code 

Abstract method to be overriden by the particular subclassed feature generator. It receives a simple sentence of any type and returns a list of features. It should be overriden by a feature generator that doesn't differentiate between source and target features

Overrides: featuregenerator.FeatureGenerator.get_features_simplesentence
(inherited documentation)

get_features_string(self, sent_string)

source code 
Overrides: featuregenerator.FeatureGenerator.get_features_string
