附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请中记载的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
图1为本申请实施例提供的一种翻译方法实施例的流程图；
图2为本申请实施例提供的一种翻译矩阵的示意图；
图3为本申请实施例提供的一种翻译装置的结构框图；
图4为本申请实施例提供的一种翻译设备的结构框图。
具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保 护的范围。
随着计算机技术的快速发展，机器学习领域也有了很多的技术进步。在机器学习领域主要是通过训练神经网络模型来代替重复的人工操作。当前机器学习也可以应用到翻译领域，可以训练神经网络模型来进行翻译。
神经网络机器翻译(Neural Machine Translation，NMT)翻译质量较高，已经成为当前最广泛的机器翻译技术。主要的翻译过程如下：将原文语句s输入NMT中，NMT中的编码器(encoder)将原文语句s编码为向量，之后寻找与原文语句s语义相似的相似语句s＇，得到相似语句s＇的相似译文语句t＇，NMT中引入额外的一个编码器(encoder)将相似译文语句t＇编码为向量，将原文语句s的向量和相似译文语句t＇进行模型计算得到原文语句s的译文语句t的向量，利用解码器(decoder)对译文语句t的向量进行解码，得到译文语句t。
经发明人研究发现，现有技术中进行翻译时，只会参考相似译文语句t＇的信息，而忽略了原文语句s的相似语句s＇的信息，会导致在翻译的过程中出现翻译不准确的问题。并且，现有技术中进行翻译需要额外引入一个新的encoder对相似译文语句t＇进行编码，增加了模型计算过程中的参数数量,翻译成本增加。若要考虑相似语句s＇的信息，则还需要重新训练翻译模型，时间消耗过大。
因此，本申请实施例提供一种翻译方法，首先确定与第一原文语句在语义上相似的第二原文语句，之后确定在第一原文语句和第二原文语句中都出现的目标原词，若目标原词在第一原文语句和第二原文语句中的译词不同，则根据目标原词被翻译为第一译词或第二译词的概率确定目标原词的目标译词。由此可见，本申请实施例的翻译方法不仅利用了第二原文语句的第二译文语句的信息，还采用了第二原文语句的信息，根据第二原文语句和第一原文语句的相似词汇信息，对第一原文语句的翻译进行校正，能够增大翻译的准确性。此外，本申请实施例中的翻译方法不需要在翻译模型中引入新的encoder对译文语句t＇编码为向量，降低了翻译成本，增大了翻译效率。
参见图1，该图为本申请实施例提供的一种翻译方法的流程图。
本实施例提供的翻译方法包括如下步骤：
S101，获取目标句对。
在本申请的实施例中，首先获取目标句对，目标句对是经过翻译模型进行翻译之后的句对。目标句对包括第一原文语句和第一译文语句，第一译文语句是第一原文语句经翻译模型进行翻译后得到的语句，第一译文语句可能会有翻译错误。
作为一种示例，第一原文语句可以是“她是一个来自中国的学生”，第一译文语句可以是“She is a student to China”，其中，第一译文语句中的词to翻译错误。
本申请实施例应用的翻译模型可以为神经网络机器翻译(Neural Machine Translation，NMT)模型。
S102，根据所述第一原文语句获取参考句对。
在本申请的实施例中，根据第一原文语句获取参考句对，参考句对包括第二原文语句和第二译文语句，其中，第二译文语句是第一原文语句的译文，第二译文语句是第一原文语句的正确译文。第一原文语句与第二原文语句在语义上相似，可以在翻译 记忆库中查询与第一原文语句语义相似的第二原文语句。
在实际应用中，第一原文语句和第二原文语句在语义上相似。语义上相似可以有以下两种实现方式：第一种实现方式是通过比较得知第一原文语句和第二原文语句中相似词汇的比例，当相似词汇达到预定的比例，即认为第一原文语句和第二原文语句在语义上相似；第二种实现方式是将第一原文语句和第二原文语句编码为向量之后，计算向量之间的相似度，当向量之间的相似度达到预定的比例，即认为第一原文语句和第二原文语句在语义上相似。
作为一种示例，第一原文语句可以是“她是一个来自中国的学生”，第一译文语句可以是“She is a student to China”；第二原文语句可以是“他是一个来自美国的老师”，第二译文语句可以是“He is a teacher from America”。
S103，确定所述第一原文语句中的目标原词。
在本申请的实施例中，目标原词为既出现在第一原文语句又出现在第二原文语句中的词。在确定与第一原文语句的语义相似的第二原文语句之后，可以比较第一原文语句和第二原文语句中的词，将既出现在第一原文语句中又出现在第二原文语句中的词，确定为目标原词。
在实际应用中，在确定第一原文语句中的目标原词时，可以对第一原文语句和第二原文语句进行逐个词汇比较，得到既出现在第一原文语句中又出现在第二原文语句中的词。
作为一种示例，第一原文语句可以是“她是一个来自中国的学生”，第二原文语句可以是“他是一个来自美国的老师”。通过逐个词汇的比较可以确定第一原文语句中的目标原词有“是”、“一个”、“来自”和“的”。
也可以不采用逐个词汇比较的方式确定目标原词，例如将第一原文语句和第二原文语句按照语法进行分割，得到几个部分，对比第一原文语句和第二原文语句相应的部分，确定目标原词。S104，响应于第一译词和第二译词不同，根据所述目标原词的第一概率和第二概率确定所述目标原词的目标译词。
在本申请的实施例中，第一译词为目标原词在第一译文语句中对应的词，第二译词为目标原词在第二译文语句中对应的词，第一概率为目标原词在第一译文语句中被翻译为第一译词的概率，第二概率为目标原词在第二译文语句中被翻译为第二译词的概率。在本申请的实施例中，目标原词在第一译文语句中的第一译词和在第二译文语句中的第二译词可能不同，此时可以根据目标原词在第一译文语句中被翻译为第一译词的第一概率和在第二译文语句中被翻译为第二译词的第二概率，确定目标原词的目标译词，目标译词为目标原词对应的正确的翻译词。在实际应用中，第一概率是将第一原文语句输入到翻译模型得到的。主要的翻译过程如下：将第一原文语句输入到翻译模型中，翻译模型中的编码器(encoder)将第一原文语句编码为向量，进行翻译得到第一译文语句的向量，利用解码器(decoder)对第一译文语句的向量进行解码，得到第一译文语句，此时目标原词在第一译文语句中被翻译为第一译词的概率为第一概率。
在实际应用中，第二概率是将第二原文语句和第二译文语句输入到翻译模型得到的。将第二原文语句和第二译文语句输入翻译模型，翻译模型对第二原文语句和第二译文 语句进行强制解码，即将第二原文语句和第二译文语句编码为向量，得到目标原词在第二原文语句中被翻译为第二译词的第二概率。由此可见，本申请实施例中的翻译方法不需要在翻译模型中引入新的encoder对第二译文语句编码为向量，只需要利用翻译模型中原本具有的encoder和decoder对第二原文语句和第二译文语句进行强制解码，即可得到第二概率，也就是本申请实施例的方法降低了翻译成本，增大了翻译效率。
参考表1所示，为将第一原文语句输入到翻译模型，得到第一原文语句中的词被翻译的概率。
表1
  She is a student to China
她 0.8 0.02 0.02 0.02 0.02 0.02
是 0.02 0.8 0.02 0.02 0.02 0.02
一个 0.1 0.1 0.7 0.03 0.03 0.04
来自 0.05 0.01 0.01 0.1 0.5 0.08
中国 0.02 0.02 0.02 0.02 0.02 0.9
的 0.1 0.2 0.13 0.15 0.15 0.1
学生 0.02 0.02 0.02 0.9 0.02 0.02
由表1可以看出，第一原文语句中的目标原词“一个”被翻译为“a”的第一概率为0.7，第一原文语句中的目标原词“来自”被翻译为“to”的第一概率为0.5，第一原文语句中的目标原词“来自”被翻译为“from”的概率为0.3，也就是说，由于将第一原文语句输入翻译模型，得到第一原文语句中的词“来自”被翻译为“to”的概率最大，为0.5，因此翻译模型在翻译第一原文语句的时候翻译错误，将“来自”错误的翻译为了“to”。
参考表2或图2所示，为将第二原文语句和第二译文语句输入到翻译模型，得到第二原文语句中的词被翻译为第二译文语句中的词的概率。
表2
Figure PCTCN2022092392-appb-000001
由表2或图2可以看出，第二原文语句中的词“他”被翻译为“He”的概率为0.8，第二原文语句中的目标原词“一个”被翻译为“a”的第二概率为0.7，第一原文语句中的目标原词“来自”被翻译为“from”的第二概率为0.8。
在本申请的实施例中，确定目标原词的目标译词可以有以下两种实现方式：
在第一种可能的实现方式中，根据目标原词的第一概率和第二概率确定目标原词的目标译词可以有以下三种情况：
第一种情况为第一概率小于第二概率，将第二译词确定为目标原词的目标译词。也就是说，若目标原词翻译为第一译词的概率小于翻译为第二译词的概率，则目标译词为第二译词。
作为一种示例，将目标原词“来自”翻译为第一译词“to”的第一概率为0.5，将目标原词“来自”翻译为第二译词“from”的第二概率为0.8，第一概率0.5小于第二概率0.8，则确定目标原词“来自”的目标译词为第二译词“from”。
第二种情况为第一概率大于第二概率，将第一译词确定为目标原词的目标译词。也就是说，若目标原词翻译为第一译词的概率大于翻译为第二译词的概率，则目标译词为第一译词。
作为一种示例，将目标原词“来自”翻译为第一译词“to”的第一概率为0.8，将目标原词“来自”翻译为第二译词“from”的第二概率为0.5，第一概率0.8大于第二概率0.5，则确定目标原词“来自”的目标译词为第一译词“to”。
第三种情况为第一概率等于第二概率，将第一译词或第二译词确定为目标原词的目标译词。也就是说，若目标原词翻译为第一译词的概率等于翻译为第二译词的概率，则目标译词为第一译词或第二译词。
作为一种示例，将目标原词“来自”翻译为第一译词“to”的第一概率为0.7，将目标原词“来自”翻译为第二译词“from”的第二概率为0.7，第一概率0.7等于第二概率0.7，则确定目标原词“来自”的目标译词为第一译词“to”或第二译词“from”。
在第二种可能的实现方式中，根据第二概率和第三概率得到第四概率，根据第一概率和第四概率确定目标原词的目标译词，其中，第三概率为将第一原文语句输入到翻译模型中得到的目标原词被翻译为第二译词的概率。在实际应用中，可以将第二概率和第三概率加权求和，得到第四概率。通过利用第二概率和第三概率得到第四概率的方式来辅助确定目标译词，能够增强本申请实施例提供的翻译方法的翻译质量。
在实际应用中，可以比较第一概率和第四概率的大小，将较大的概率对应的译词确定为目标译词。若第一概率小于第四概率，则将第四概率对应的第二译词确定为目标译词；若第一概率大于第四概率，则将第一概率对应的第一译词确定为目标译词；若第一概率等于第四概率，则将第一概率对应的第一译词确定为目标译词或将第四概率对应的第二译词确定为目标译词。
作为一种示例，将第一原文语句输入到翻译模型中，目标原词“来自”被翻译为第一译词“to”的第一概率为0.5，目标原词“来自”被翻译为第二译词“from”的第三概率为0.3，将第二原文语句输入到翻译模型中，目标原词“来自”被翻译为第二译词“from”的第二概率为0.8。将第二概率0.8和第三概率0.3加权求和，得到第四概率，即第四概率＝(0.8+0.3)×0.5＝0.55，第四概率0.55大于第一概率0.5，则将第四概率对应的第二译词“from”确定为目标译词。
S105，根据所述目标原词的目标译词确定所述第一原文语句的目标译文语句。
在本申请的实施例中，可以根据确定的目标原词的目标译词，确定第一原文语句的目 标译文语句。
作为一种示例，若目标原词“来自”翻译为第一译词“to”的第一概率小于目标原词“来自”翻译为第二译词“from”的第二概率，则确定目标原词“来自”的目标译词为第二译词“from”，将第一译文语句中的第一译词“to”修正为第二译词“from”，得到目标译文语句。
本申请实施例提供一种翻译方法，首先确定与第一原文语句在语义上相似的第二原文语句，之后确定在第一原文语句和第二原文语句中都出现的目标原词，若目标原词在第一原文语句和第二原文语句中的译词不同，则根据目标原词被翻译为第一译词或第二译词的概率确定目标原词的目标译词。由此可见，本申请实施例的翻译方法不仅利用了第二原文语句的第二译文语句的信息，还采用了第二原文语句的信息，根据第二原文语句和第一原文语句的相似词汇信息，对第一原文语句的翻译进行校正，能够增大翻译的准确性。此外，本申请实施例中的翻译方法不需要在翻译模型中引入新的encoder对译文语句t＇编码为向量，降低了翻译成本，增大了翻译效率。
