A pairwise parallel sentence, is a parallel sentence that contains output produced by only two systems.

__init__(self, source=None, translations=[], systems=[], reference=None, attributes={}, rank_name=u'rank', **kwargs)
Constructor source code

_cast(self, parallelsentence)
Reload in place a pairwise parallelsentence which has the type of a simple parallelsentence

source code

_normalize_ranks(self, invert_ranks=False)
Reads the two rank scores for the two respective system outputs, compares them and sets a universal comparison value, namely -1 if the first system is better, +1 if the second system output is better, and 0 if they are equally good.

Method Details

init(self, source=None, translations=`[]`, systems=`[]`, reference=None, attributes=`{}`, rank_name=`u'rank'`, **kwargs)
(Constructor)

source code

Constructor

Parameters:

source (SimpleSentence) - the source text of the parallel sentence
translations (tuple of translations (SimpleSentence, SimpleSentence)) - a pair of translations
reference (SimpleSentence) - The desired translation provided by the system
the, attributes (dict { String name : String value }) - that describe the parallel sentence
systems (tuple of strings) - names of target systems
cast - set True if you want to initialize a pairwise parallel sentence out of a simple parallel sentence

Overrides: object.__init__

_cast(self, parallelsentence)

source code

Reload in place a pairwise parallelsentence which has the type of a simple parallelsentence

Parameters:

parellesenentence - the simple parallelsentence
parallelsentence (ParallelSentence)

_normalize_ranks(self, invert_ranks=False)

source code

Reads the two rank scores for the two respective system outputs, compares them and sets a universal comparison value, namely -1 if the first system is better, +1 if the second system output is better, and 0 if they are equally good. The value is set as a new argument of the current object

Parameters:

invert_ranks (boolean) - If set to True, it inverts the ranks (useful for non-penalty metrics)

get_rank(self)

source code

provide the rank value of the parallel sentence return: the rank value rtype: string

Overrides: parallelsentence.ParallelSentence.get_rank: (inherited documentation)

get_translations(self)

source code

Overrides: parallelsentence.ParallelSentence.get_translations
