Machine translation using global lexical selection and sentence reconstruction

摘要

Disclosed are systems, methods, and computer-readable media for performing translations from a source language to a target language. The method comprises receiving a source phrase, generating a target bag of words based on a global lexical selection of words that loosely couples the source words/phrases and target words/phrases, and reconstructing a target phrase or sentence by considering all permutations of words with a conditional probability greater than a threshold.

主权项

1. A method comprising:
classifying, via a processor, a source phrase in a source language into a phrase meaning; matching, via the processor, the phrase meaning to a target phrase automaton in a target language wherein:
the target phrase automaton comprises a plurality of states and a plurality of arcs interconnecting the plurality of states to define a sentence path, each of the plurality of states defining a word position slot for inserting a word from a bag of words, and each of the plurality of arcs associated with a pre-defined insertion cost for inserting the word from the bag of words based on a previous state in the sentence path; andthe pre-defined insertion cost is associated with one of penalizing and rewarding the sentence path based on how many words are in the sentence path, in order to produce more words in a target sentence relative to the source phrase; determining, via the processor, a target sentence probability for the sentence path based on one of a lexical translation of words in the source phrase and a phrase-to-phrase mapping; and upon determining that the sentence path has a probability above a threshold, constructing, via the processor, the target sentence using the sentence path.
