AlignedSent
(words, mots, alignment=None)[source]¶ Return an aligned sentence object, which encapsulates two sentences along with an
Alignment
between them.>>> from nltk.translate import AlignedSent, Alignment >>> algnsent = AlignedSent(['klein', 'ist', 'das', 'Haus'], ... ['the', 'house', 'is', 'small'], Alignment.fromstring('0-2 1-3 2-1 3-0')) >>> algnsent.words ['klein', 'ist', 'das', 'Haus'] >>> algnsent.mots ['the', 'house', 'is', 'small'] >>> algnsent.alignment Alignment([(0, 2), (1, 3), (2, 1), (3, 0)]) >>> from nltk.corpus import comtrans >>> print(comtrans.aligned_sents()[54]) <AlignedSent: 'Weshalb also sollten...' -> 'So why should EU arm...'> >>> print(comtrans.aligned_sents()[54].alignment) 0-0 0-1 1-0 2-2 3-4 3-5 4-7 5-8 6-3 7-9 8-9 9-10 9-11 10-12 11-6 12-6 13-13
