best_model2_alignment
(sentence_pair, j_pegged=None, i_pegged=0)¶ Finds the best alignment according to IBM Model 2
Used as a starting point for hill climbing in Models 3 and above, because it is easier to compute than the best alignments in higher models
Parameters: - sentence_pair (AlignedSent) – Source and target language sentence pair to be word-aligned
- j_pegged (int) – If specified, the alignment point of j_pegged will be fixed to i_pegged
- i_pegged (int) – Alignment point to j_pegged
