prob_all_alignments
(src_sentence, trg_sentence)[source]¶ Computes the probability of all possible word alignments, expressed as a marginal distribution over target words t
Each entry in the return value represents the contribution to the total alignment probability by the target word t.
To obtain probability(alignment | src_sentence, trg_sentence), simply sum the entries in the return value.
Returns: Probability of t for all s in src_sentence
Return type: dict(str): float
