Background

In machine translation, sentences are generally input into a translation system for translation, and then a translation produced by the translation system is obtained. In a real translation scenario, sentences are not independent of each other, but have a context relationship. Translations produced by a translation system that are only sentence-level may be perfect at the single-sentence level, but the results of sentence-by-sentence translation are not necessarily optimal from the overall context level of the sentence.

Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic diagram according to a first embodiment of the present disclosure. As shown in fig. 1, the training method of the translation model in this embodiment may specifically include the following steps:

s101, obtaining first training data, wherein the first training data comprises a plurality of first training texts, forward texts of the first training texts and translation labeling results of the first training texts;

s102, constructing a neural network model comprising a memory module, an encoding module and a decoding module, wherein the memory module is used for outputting an updated memory vector and a second encoding vector which is used for being input into the decoding module according to a current memory vector and a first encoding vector obtained by the encoding module;

s103, training the neural network model by using the plurality of first training texts, the foreword texts of the plurality of first training texts and the translation labeling results of the plurality of first training texts to obtain a translation model.

In the training method of the translation model of this embodiment, a neural network model including a memory module is constructed, so that the neural network model translates a first training text in combination with a memory vector dynamically updated by the memory module, and because the input of the coding module further includes a previous text of the first training text, the memory module can continuously update the memory vector according to the previous information, thereby achieving the purpose of translating a next first training text by using the updated memory vector by the neural network model, so that the translation model obtained by training can translate a current text in combination with the updated memory vector and the previous two previous information of the directly input text, thereby ensuring that the previous information is maximally utilized during translation, and improving the accuracy of a translation result obtained by the translation model.

In this embodiment, when S101 is executed to obtain first training data, different texts obtained from the same chapter may be used as a plurality of first training texts, where each first training text is a text to be translated in a training process; the text in the front of each first training text, specifically, the whole text or a part of text in the chapters before the first training text, in this embodiment, a plurality of consecutive texts before the first training text may be used as the text in the front of the first training text; the translation marking results of the plurality of first training texts are marked in advance, and the translation marking results of the first training texts are correct translation results of the first training texts.

In this embodiment, the first training text and the translation labeling result respectively correspond to different languages, that is, the first training data obtained by performing S101 in this embodiment is a chapter-level parallel corpus.

In addition, when the first training data is obtained in S101, the embodiment may also obtain a plurality of first training texts from different chapters; in order to ensure the training accuracy of the neural network model, a plurality of first training texts belonging to the same chapter are required to complete one training process of the neural network model, and then a translation model is obtained through a plurality of training processes.

In this embodiment, after the first training data including the plurality of first training texts, the text of the previous paragraphs of the plurality of first training texts, and the translation labeling result of the plurality of first training texts is obtained in S101, S102 is performed to construct a neural network model including a memory module, an encoding module, and a decoding module.

In the embodiment, the neural network model constructed by step S102 is implemented, where the encoding module is an encoder based on a Transformer structure, and the encoding module is configured to output an encoding vector corresponding to the first training text and an encoding vector corresponding to the preceding text according to the input first training text and the preceding text of the first training text, respectively; in this embodiment, the encoding vector corresponding to the text is specifically a vector sequence formed by encoding results of word segmentation results in the text.

When obtaining the first coding vector according to the first training text and the text in the foregoing of the first training text, the coding module in this embodiment may splice the coding vector corresponding to the first training text and the coding vector corresponding to the text in the foregoing, and use the spliced result as the first coding vector; the average value of the code vectors can be calculated according to the code vector corresponding to the first training text and the code vector corresponding to the preceding text, and the calculation result is used as the first code vector.

However, when the result of splicing the text code vectors is used as the first code vector, the first code vector is redundant; when the average value of the code vectors of the text is used as the first code vector, there is a problem that the first code vector loses text information.

Therefore, in order to avoid the problems of redundancy and text information loss of the first encoding vector and improve the accuracy of the obtained first encoding vector, the encoding module in this embodiment may adopt an optional implementation manner when obtaining the first encoding vector: respectively outputting an encoding vector corresponding to the initiator, an encoding vector corresponding to the first training text and an encoding vector corresponding to the preceding text of the first training text according to the input initiator, the first training text and the preceding text of the first training text; the code vector corresponding to the start symbol is taken as the first code vector.

In this embodiment, the start character used as the input of the encoding module is a special character indicating the start of input; the encoding module obtains the encoding vector corresponding to the start symbol according to the first training text and the text, and the encoding vector corresponding to the start symbol includes text information of the inputted text, so that the encoding vector corresponding to the start symbol is inputted to the memory module as the first encoding vector.

In this embodiment, the start symbol, the previous text (including different texts in the previous text) and the first training text may be separated by a separator, so that a translation output result corresponding to the first training text is determined in the output result of the decoding module according to the used separator.

In the embodiment, executing the Neural Network model constructed in S102, the memory module may be implemented based on a Recurrent Neural Network (RNN), and the memory module is configured to output the updated memory vector and a second encoding vector for inputting to the decoding module according to the current memory vector and the first encoding vector obtained by the encoding module; the memory module uses the current memory vector to translate the current first training text, and outputs the updated memory vector to translate the next first training text.

That is to say, the memory module in this embodiment updates the currently used memory vector according to the currently input first training text and the preamble text of the first training text, and continuously stores the preamble information by updating the memory vector, so as to achieve the purpose of sufficiently utilizing the preamble information to perform translation, thereby improving the translation accuracy of the first training text.

It is understood that, in the present embodiment, when the first training text is translated, the memory vector used may be a preset vector, and the preset vector may be a zero vector.

In the embodiment of the neural network model constructed by step S102, the decoding module is a decoder based on the transform result, and the decoding module is configured to output a translation output result corresponding to the first training text according to the second decoding vector output by the memory module and the encoding vector corresponding to the first training text and the encoding vector corresponding to the preceding text output by the encoding module.

In this embodiment, after the step S102 of constructing the neural network model including the memory module, the encoding module and the decoding module is performed, the step S103 of training the neural network model by using the plurality of first training texts, the forward texts of the plurality of first training texts, and the translation labeling results of the plurality of first training texts is performed to obtain the translation model.

After the translation model obtained by performing the training in S103 in this embodiment is obtained, the text to be translated in the chapter to be translated and the corresponding preceding text are sequentially used as the input of the translation model, and the translation result of each text to be translated output by the translation model is obtained, so that the translation result of the chapter to be translated is obtained.

Specifically, when executing S103 to train the neural network model by using the translation labeling result of the multiple first training texts, the text preambles of the multiple first training texts, and the multiple first training texts, to obtain the translation model, the present embodiment may adopt an optional implementation manner as follows: for each first training text, taking the first training text and a preceding text of the first training text as the input of a coding module to obtain a first coding vector output by the coding module, a coding vector corresponding to the first training text and a coding vector corresponding to the preceding text; taking the current memory vector and the first encoding vector as the input of a memory module to obtain an updated memory vector and a second encoding vector which are output by the memory module, wherein the output updated memory vector is used for the translation of the next first training text; taking the second encoding vector, the encoding vector corresponding to the first training text and the encoding vector corresponding to the preceding text as the input of a decoding module to obtain a translation output result which is output by the decoding module and corresponds to the first training text; and calculating a loss function value by using the translation marking result and the translation output result of the first training text, and adjusting the parameters of the neural network model according to the calculated loss function value until the neural network model converges to obtain the translation model.

According to the method, when the preceding text of the first training text is used for training the neural network model, the memory module in the neural network model dynamically updates the memory vector in which the preceding information is stored, so that the purpose that the neural network model translates the next first training text by using the updated memory vector is achieved, the translation model obtained by training can be combined with the two kinds of preceding information, namely the continuously updated memory vector and the directly input preceding text, so that the maximum utilization of the preceding information during translation is ensured, and the accuracy of the translation result obtained by the translation model is improved.

The number of the first training data may affect the translation effect of the translation model, and because the chapter-level parallel corpora are relatively rare, the embodiment adopts a pre-training mode, and the target model is pre-trained by using the chapter-level monolingual corpora first, and then the parameters in the pre-trained target model are initialized, so that the translation effect of the translation model is improved under the condition that the chapter-level parallel corpora are relatively few.

In this embodiment, when the step S201 is executed to obtain the second training data, different texts in the same chapter can be used as a plurality of second training texts, that is, the second training data obtained by the step S201 is a chapter-level monolingual corpus.

In this embodiment, after the pre-training of the target model is completed in S202, parameters of the target encoding module and parameters of the target decoding module in the pre-trained target model may be obtained, and then when the neural network model including the memory module, the encoding module and the decoding module is constructed in S203, the parameters of the encoding module and the decoding module in the neural network model are initialized using the obtained parameters, respectively.

According to the translation method, the to-be-translated chapters are translated through the translation model obtained through pre-training, and the translation model can be used for translating the to-be-translated text by combining the continuously updated memory vector and the input fore information, so that the fore information is utilized to the maximum extent, and the accuracy of the obtained translation result is improved.

In this embodiment, when the S301 is executed to obtain the chapters to be translated, the document input by the user may be used as the chapters to be translated, or the document obtained from the network may be used as the chapters to be translated.

In this embodiment, when the S301 is executed to determine the text to be translated in the chapter to be translated, all sentences in the chapter to be translated may be taken as the text to be translated by taking the sentences as units; in the embodiment, when the S301 is executed to determine the preceding text of the text to be translated, a preset number of texts in the chapter to be translated before the text to be translated may be used as the preceding text, for example, 3 texts before the text to be translated are used as the preceding text of the text to be translated.

In this embodiment, when executing S302 to input, for each text to be translated, the text to be translated and the previous text of the text to be translated into a translation model, an optional implementation manner that can be adopted is as follows: inputting the initial symbol, the text to be translated and the preceding text of the text to be translated into the translation model, wherein the input initial symbol is used for a coding module in the translation model to obtain a first coding vector to be input into the memory module.

That is to say, the memory module constructed by the construction unit 502 updates the currently used memory vector according to the currently input first training text and the preamble text of the first training text, so that the memory vector is continuously stored with the preamble information by updating the memory vector, thereby achieving the purpose of sufficiently utilizing the preamble information for translation, and improving the translation accuracy of the first training text.

It is understood that, in the present embodiment, when the first training text is translated, the memory vector used may be a preset vector, and the preset vector may be a zero vector.

In the neural network model constructed by the construction unit 502, the decoding module is a decoder based on the transform result, and the decoding module is configured to output a translation output result corresponding to the first training text according to the second decoding vector output by the memory module and the encoding vector corresponding to the first training text and the encoding vector corresponding to the preceding text output by the encoding module.

When the building unit 502 builds the neural network model including the memory module, the encoding module and the decoding module, the following method may also be adopted: acquiring second training data, wherein the acquired second training data comprises a plurality of second training texts; pre-training the target model by using a plurality of second training texts to obtain parameters of a target coding module and parameters of a target decoding module in the pre-trained target model; the method comprises the steps of constructing a neural network model comprising a memory module, an encoding module and a decoding module, initializing parameters of the encoding module in the neural network model by using parameters of a target encoding module, and initializing parameters of the decoding module in the neural network model by using parameters of the target decoding module.

When the building unit 502 obtains the second training data, different texts in the same chapter can be used as a plurality of second training texts, that is, the second training data obtained by the building unit 502 is a chapter-level monolingual corpus.

The target model in the embodiment comprises a target coding module and a target decoding module, and the target model can be an mBART model; the building unit 502 may pre-train the target model by using a plurality of second training texts through an existing pre-training manner, for example, after performing masking processing on the second training texts, the target model is trained by using a result of the masking processing and the second training texts.

In this embodiment, after the building unit 502 builds the neural network model including the memory module, the encoding module and the decoding module, the training unit 503 trains the neural network model using the plurality of first training texts, the translation labeling results of the preceding texts of the plurality of first training texts and the plurality of first training texts, so as to obtain the translation model.

After the obtained translation model is trained by the training unit 503 and the chapters to be translated are obtained, the texts to be translated in the chapters to be translated and the corresponding preceding texts thereof are sequentially used as the input of the translation model, and the translation results of the chapters to be translated can be obtained after the translation output results corresponding to each text to be translated and output by the translation model are obtained.

Specifically, when the training unit 503 trains the neural network model using the translation labeling result of the plurality of first training texts, the forward texts of the plurality of first training texts, and the plurality of first training texts to obtain the translation model, an optional implementation manner that can be adopted is as follows: for each first training text, taking the first training text and a preceding text of the first training text as the input of a coding module to obtain a first coding vector output by the coding module, a coding vector corresponding to the first training text and a coding vector corresponding to the preceding text; taking the current memory vector and the first encoding vector as the input of a memory module to obtain an updated memory vector and a second encoding vector output by the memory module; taking the second encoding vector, the encoding vector corresponding to the first training text and the encoding vector corresponding to the preceding text as the input of a decoding module to obtain a translation output result which is output by the decoding module and corresponds to the first training text; and calculating a loss function value by using the translation marking result and the translation output result of the first training text, and adjusting the parameters of the neural network model according to the calculated loss function value until the neural network model converges to obtain the translation model.

Fig. 6 is a schematic diagram according to a sixth embodiment of the present disclosure. As shown in fig. 6, the translation apparatus 600 of the present embodiment includes:

the second obtaining unit 601 is configured to obtain chapters to be translated, and determine texts to be translated in the chapters to be translated and preceding texts of the texts to be translated;

the translation unit 602 is configured to, for each text to be translated, input the text to be translated and a preceding text of the text to be translated into a translation model, and obtain a translation output result of the text to be translated according to an output result of the translation model;

the processing unit 603 is configured to output a result according to the translation of each text to be translated, so as to obtain a translation result of the chapter to be translated.

The second obtaining unit 601 may use a document input by a user as a chapter to be translated when obtaining the chapter to be translated, or use a document obtained from a network as the chapter to be translated.

When the second obtaining unit 601 determines the text to be translated in the chapter to be translated, all sentences in the chapter to be translated can be used as the text to be translated by taking the sentences as units; the second obtaining unit 601 may use a preset number of texts in the chapter to be translated before the text to be translated as the preceding text when determining the preceding text of the text to be translated.

When the translation unit 602 inputs, for each text to be translated, the text to be translated and the preceding text of the text to be translated into the translation model, the optional implementation manners that can be adopted are as follows: inputting the initial symbol, the text to be translated and the preceding text of the text to be translated into the translation model, wherein the input initial symbol is used for a coding module in the translation model to obtain a first coding vector to be input into the memory module.

When the processing unit 603 obtains the translation result of the chapter to be translated according to the translation output result of each text to be translated, the processing unit 603 may sequentially splice the translation output results of the texts to be translated according to the sequence of the texts to be translated in the chapter to be translated, so as to use the spliced result of the translation output results as the translation result of the chapter to be translated.
