It can reduce the word error probability of PPK system further or make the energy efficiency of PPK system higher under the condition of given tolerable error probability .

它能进一步降低PPK体制的 误字 率、或在一定 容错 概率下进一步提高PPK体制的能量效率。

The translation choice is realized on the basis of a grammar tree and takes the context as a word bag with the lexicon and POS tag information as context features . The Bayes minimal error probability is taken as the evaluation function of the candidate translation .

基于句法结构的译文选择将句法上下文集合视为 词包，统计集合中各词的词信息和词性信息作为上下文特征，以Bayes最小 错误 概率 公式作为评价函数选择译文。
