featuregenerator.hjerson.Hjerson

Class Hjerson

object --+ | featuregenerator.FeatureGenerator --+ | languagefeaturegenerator.LanguageFeatureGenerator --+ | Hjerson

This is a class that wraps the Hjerson functionality on a sentence level.

Instance Methods

[hide private]

__init__(self, **kwargs)
By initializing Hjerson, we maintain a tokenizer (if needed) and a treetager object so that they are available for sentence-level calls

source code

{str: object, ... }

get_features_tgt(self, simplesentence, parallelsentence)
Override language feature generator function in order to return sentence level error classes

source code

_tag(self, string)

source code

get_features_strings(self, target_string, references)
Process one sentence, given the translated sentence (hypothesis) and the corresponding reference

source code

analyze(self, hline, basehline, addhline, refs, baserefs, addrefs)
This functions hosts the core sentence-level functionality of Hjerson, as written originally by Maja Popovic.

init(self, **kwargs)
(Constructor)

source code

By initializing Hjerson, we maintain a tokenizer (if needed) and a treetager object so that they are available for sentence-level calls

Parameters:

tokenize (boolean) - specify if tokenizer should be run by Hjerson, false if it has already happened
lang (str) - specify which language is the content using the language 2-letter iso code
tagdir (str) - specify the directory where the treetager bin folder exists

Overrides: object.__init__

get_features_tgt(self, simplesentence, parallelsentence)

source code

Override language feature generator function in order to return sentence level error classes

Parameters:

simplesentence - a simple sentence object, containing the target sentence @type sentence.sentence.SimpleSentence
parallelsentence - a parallel sentence object which is needed to derive the reference @type sentence.parallelsentence.ParallelSentence

Returns: {str: object, ... }

a dictionary with the attributes retrieved

Overrides: featuregenerator.FeatureGenerator.get_features_tgt

get_features_strings(self, target_string, references)

source code

Process one sentence, given the translated sentence (hypothesis) and the corresponding reference

Parameters:

target_string (str) - the translation hypothesis produced by the system
references (list(str)) - a list of strings, containing the correct translations

analyze(self, hline, basehline, addhline, refs, baserefs, addrefs)

source code

This functions hosts the core sentence-level functionality of Hjerson, as written originally by Maja Popovic. It operates after all sentence-level strings have been retrieved and passed as parameters

Parameters:

hline
