Description

Server and translation method for translation

The examples below relate to translation techniques.

As exchanges between countries increase, the necessity of research to improve the performance of translation technology is increasing. As Internet technologies become more common, attempts to expand or integrate the platform of a network-based service are increasing. As a platform expansion, the performance of translation technology is required to provide smooth communication between different languages.

In order to provide an intuitive and more convenient user interface, an interface scheme based on user's touch, motion, and image recognition has been proposed. Among these interface methods, the voice recognition-based interface adopts language, which is a basic means of communication between people, and thus enhances user experience and accessibility of the interface.

Recently, since the machine learning-based translation technique is widely adopted, the amount of acquired training data becomes an important factor that makes a difference in the performance of the translation engine. However, since the amount of the learning data is different for each language, the difference in the amount of the learning data may cause a performance gap of the translation engine between languages. If the performance gap of the translation engine widens, the development of translation technology for languages in regions with poor IT (Information Technology) environments may be delayed. Therefore, development of translation technology considering the performance of translation between languages is required.

The server may generate bidirectional optimal translation paths as shown in FIG. 2 in consideration of time or speed for generating an optimal translation path, or generate optimal translation paths independent of FIG. 3 and B. FIG.

Referring to FIG. 4, the server may generate an optimal translation path based on a user's selection. The server may output translation engines and relay languages for translating an input language of Korean into a relay language. The server may output translation accuracy and translation speeds corresponding to translation engines and relay languages to induce a user's selection. Here, the translation accuracy can be updated based on the evaluation results by the users. For example, the evaluation result may be defined as discretely distinguished or continuous values, such as "upper, upper, middle, middle, lower and lower".

The server may generate an optimal translation path based on the translation engine selected from the user and the relay language. The server may output translation engines and relay languages for translation between the texts of the relay languages, and generate an optimal translation path based on the translation engine and the relay language selected from the user.

Referring to FIG. 4, the server may select a translation engine A for translating Korean text and Japanese as a relay language based on a user's selection result, and a translation engine B and a relay language for translating Japanese text. You can select Chinese separately, and choose a translation engine C for translating Chinese text. The server may generate an optimal translation path based on the user's selection result in "Korean-> Japanese (Translation Engine A)-> Chinese (Translation Engine B)-> English (Translation Engine C)". The number of relay languages may be a preset value or may be adaptively set according to a user's selection. If the relay language is not selected by the user, the server may generate an optimal translation path to translate the text into the text of the target language according to the selection result of the translation engine.

Referring to FIG. 5, the server for translation may obtain a first translation accuracy between an input language and a target language (501). The server is a server that processes operations for translation and may be implemented as a software module, a hardware module, or a combination thereof. The server may execute an application or a program for performing the translation method, and load the application program recorded in the internal memory. Application programs recorded in the internal memory may be executed through wireless communication with the server.

The server may access the server based on a wireless communication network, and the wireless communication network for accessing the server may be a communication standard of a mobile communication device such as Wifi, 2G, 3G, 4G, 5G, and LTE, and next generation communication standards. Smart phones, tablet PCs, notebook computers, wearable devices, portable devices, and the like capable of executing various applications through communication with a server.

The input language is a language of text to be translated and may be, for example, a country-specific language such as Korean, Chinese, English, or Spanish. Here text includes characters, words and sentences expressed in the input language. For example, when the input language is Korean, the text of the input language may be expressed by Korean characters, words, and sentences such as "ㄱ", "school", and "hello". The target language means that other language when the text of the input language is to be translated into the text of another language. For example, if the target language is German, the text "hello" of the input language may be translated into the text "Hallo" of the target language. The server may receive the selected information from the user to identify the input language and the target language.

According to an embodiment, the server may receive a voice of an input language and recognize the input language based on the received voice to identify the input language. The server may convert the voice of the recognized input language into the text of the input language. The server may detect a voice of the input language and recognize the input language based on the detected voice pattern. The server may receive the text input from the user and recognize the input language based on the pattern of the received text. The server may also receive text in the input language from an external server or device.

The server according to an embodiment may obtain a first translation accuracy between the input language and the target language from a pre-built database. The database may be implemented as a memory included in the server or an external device such as a server that can be connected to the server by wire, wireless, or network.

Translation accuracy A between a plurality of languages can be recorded in a database as shown in FIG. 6. The server may identify the input language and the target language and obtain a first translation accuracy between the input language and the target language from the database. For example, if the input language is Korean and the target language is English, the server may request A ( 1, 2) can be obtained. Here, the translation accuracy is a parameter regarding how accurate the translation between the two languages is. The translation accuracy may be set to a different value depending on the direction of the translation (eg, first language-> second language or second language-> first language), or may be defined as a value independent of the direction of translation. The unit may be defined in various ways according to the design intention, for example, it may be expressed in%.

The translation accuracy between the first language and the second language may include an amount of retention of translation data between the first language and the second language; A word order agreement rate between the first language and the second language; Whether the capacity of the characters of the first language matches the capacity of the characters of the second language; And feedback corresponding to the translation between the first language and the second language, based on at least one element, and the translation accuracy may be updated as these elements are updated. Here, the capacity of a character means a capacity required to express a character of a specific language. For example, Korean Hangul can be represented by 2 bits, and English alphabet can be represented by 1 bit, so the capacity of the Hangul and the alphabet does not match. Translation accuracy may be defined by weighting elements that affect translation accuracy. For example, the translation accuracy may be defined by differently setting the weight of the retained amount of translation data and the weight of the word order matching ratio. As described above, the method of defining the translation accuracy may be applied by applying various techniques according to the design intention.

According to one embodiment, the translation accuracy may be an indicator related to the performance of the translation engine providing translation between specific languages. Here, the translation engine may be an independent server or device separate from the server according to an embodiment. The server may transmit the text of the input language to the translation engine, and receive the text of the target language as the translation result from the translation engine. The translation accuracy recorded in the database may be translation accuracy of the plurality of translation engines. In this case, the server may process an operation of selecting translation engines for translating the text of the input language into the text of the target language based on the translation accuracy recorded in the database. Translation accuracy can be obtained from the execution subject of the translation engine and recorded in the database.

According to one embodiment, the database may record translation time corresponding to translation accuracy. In this case, the translation time required may be recorded in a relation mapped to the translation accuracy. The server may select translation engines for translating text in the input language into text in the target language, taking into account translation accuracy and translation time requirements.

Referring again to FIG. 5, the server may obtain second translation accuracy between the input language and the plurality of languages (502). According to an embodiment, the plurality of languages may include languages other than the target language among languages recorded in the database. For example, if the input language is Korean and the target language is German, the server may select languages other than German from among a plurality of languages recorded in the database, and obtain second translation accuracy between Korean and the selected languages.

Referring to FIG. 5, the server may obtain third translation accuracies between the plurality of languages and the target language (503). For example, if the input language is Korean and the target language is German, the server may select languages other than German from among a plurality of languages recorded in the database, and obtain third translation accuracies between the selected languages and German.

Referring to FIG. 5, the server may generate an optimal translation path for translation between the input language and the target language based on the first translation accuracy, the second translation accuracy, and the third translation accuracy (504). Here, the translation path may be defined as a sequence of languages for translating text of an input language into text of a target language, and an optimal translation path means an optimized translation path generated by a server. For example, if the input language is a Korean target language is German, the translation path may be expressed as a sequence of languages from the input language to the target language such as "Korean-> English-> French-> Spanish-> German". .

The server may select a relay language from the plurality of languages based on the second translation accuracy and the third translation accuracy. Here, the relay language means a language between the input language and the target language among the sequence of languages constituting the translation path. The relay language may include at least one language. The server may select a translation path having the highest translation accuracy among translation paths corresponding to a plurality of languages, and determine a language belonging to the selected translation path as a relay language.

For example, when the input language is Korean and the target language is German, the translation paths corresponding to the plurality of languages may include the following examples.

Translation path 1: "Korean-> Japanese-> English-> German"

Translation path 2: "Korean-> Japanese-> German"

Translation path 3: "Korean-> English-> German"

Translation Path 4: "Korean-> English-> Spanish-> German"

If the translation accuracy of the translation path 1 is the highest among the above examples, the server may select the translation path 1 and determine the languages "Japanese" and "English" belonging to the selected translation path 1 as the relay languages. Here, the accuracy of the translation path may include: translation accuracy between the input language and the at least one relay language; Translation accuracy between at least one relay language; And translation accuracy between the at least one relay language and the target language.

For example, the accuracy of a translation path may be defined as the product of translation accuracy between languages in the sequence of languages included in the translation path. The server may obtain translation accuracy between the plurality of languages recorded as shown in FIG. 6 and calculate translation accuracy of the plurality of translation paths. Here, the plurality of translation paths are a sequence of "input language-> at least one relay language-> target language". The server selects a translation path having the highest translation accuracy among the calculated translation accuracy. When the translation path having the highest translation accuracy is a sequence of "input language-> at least one relay language-> target language", the server may determine a language belonging to the sequence as the relay language. Hereinafter, an embodiment in which an optimal translation path is generated will be described with reference to FIG. 3.

The server may be configured to perform either of a translation path that is a sequence of "input language-> at least one relay language-> target language" and a translation path of "input language-> target language" based on at least one of translation accuracy and translation time. Can be determined as the optimal translation path. The translation accuracy of the translation path, which is a sequence of "input language-> target language", is referred to as the first translation accuracy, and the translation accuracy of the translation path, which is a sequence of "input language-> at least one relay language-> target language". 4 It will be referred to as translation accuracy.

As described above, the fourth translation accuracy may be defined as the product of translation accuracy between languages belonging to the sequence of the translation path. The server may compare the first translation accuracy and the fourth translation accuracy, and determine one of a translation path corresponding to the first translation accuracy and a translation path corresponding to the fourth translation accuracy based on the comparison result. .

Referring to FIG. 7, the server optimally translates a translation path 702, which is a sequence of "Korean-> Japanese-> English-> German," among translation paths for translation between Korean input language and German target language. Can be determined by the path. The server may select a translation path 702 having the highest translation accuracy among the translation paths, and determine "Japanese" and "English" belonging to the selected translation path 702 as a relay language.

The translation accuracy of the selected translation path is referred to as the fourth translation accuracy, and the translation accuracy of the translation path 701 of "Korean-> German" is referred to as the first translation accuracy. The server may compare the fourth translation accuracy and the first translation accuracy, and determine the translation path 702 as the optimal translation path because the fourth translation accuracy is greater than the first translation accuracy. Translation accuracy of "Korean-> German" is 95%, translation accuracy of "Korean-> Japanese" is 90%, translation accuracy of "Japanese-> English" is translation accuracy of "English-> German" Since the accuracy is 88%, the first translation accuracy is 50% and the fourth translation accuracy is 75.24% (which can be calculated as 0.95 * 0.9 * 0.88).

Here, the translation accuracy is calculated as a product of the translation accuracy between the languages, but not limited to such a calculation technique, a variety of techniques such as applying a weight differentially or a penalty as the path is lengthened may be applied. If the translation performance is better when directly translating the input language from the input language to the target language than the translation accuracy or the time required for translation, the sequence including the relay language, the server determines the translation path which is a sequence of the input language and the target language. The optimal translation path can be determined.

The server may generate an optimal translation path 702 and translate the Korean text into the German text using the generated optimal translation path 702. Here, the translation operation of converting text into text of another language may be directly processed by the server or may be processed by an external server or device for each language belonging to the optimal translation path 702. Alternatively, the server may access an integrated cloud server, and translation operations according to the sequence of optimal translation paths 702 may be processed on the cloud server.

For example, the server may generate an optimal translation path 702 suitable for an input language that is Korean and a target language that is German based on the translation accuracy and translation time recorded in the database. The server queries the translation engines recorded from the database based on the generated optimal translation path 702, and uses the query result to translate the translation engine "Japanese-> English" suitable for the translation of "Korean-> Japanese". A translation engine suitable for and a translation engine suitable for translation of "English-> German" can be determined. In this case, translation between languages belonging to the optimal translation path 702 is processed through a translation engine separate from the server, and the server may generate an optimal translation path 702 and relay the translated texts. have.

According to one embodiment, the server performs the translation process through the program recorded in the internal memory or the external translation engine based on the translation accuracy and the translation time recorded in the database. It can be determined. If the performance of the translation process through the program recorded in the internal memory is superior to the translation accuracy or translation time of the translation process through the external server or the translation engine, the server may process the translation operation locally.

According to an embodiment, when the translation accuracy (first translation accuracy) between the input language and the target language exceeds the threshold accuracy, the server may determine a sequence of the input language and the target language as the optimal translation path. For example, if the translation accuracy between the input language Korean and the target language Japanese is 95% and the threshold accuracy is 90%, the server determines the sequence of "Korean-> Japanese" as the optimal translation path and additional translation paths. Or do not perform a search of the relay language.

According to an embodiment of the present disclosure, the server may select languages in which translation accuracy with an input language and translation accuracy with a target language are within a critical accuracy range among a plurality of languages, and select at least one relay language from among the selected languages. . For example, the server may select languages in which the translation accuracy is in the range of 60% to 100% (or more than 60%) among the translation accuracy between the input language Korean and the plurality of languages. The server generates translation paths that include the selected languages, and the generated translation paths can compare translation accuracy with each other.

According to an embodiment, the server may determine that the input accuracy is less than the threshold accuracy if the translation accuracy between the languages recorded in the database and the input language is less than the threshold accuracy or if the translation accuracy between the languages recorded in the database and the target language is less than the threshold accuracy. > Target language "can be determined as the optimal translation path. For example, if the input language is Vietnamese, the target language is Indonesian, the translation accuracy between Vietnamese and plural languages is less than 60% and the translation accuracy between plural languages and Indonesian is less than 60%, Indonesia "sequence can determine the translation path.

According to an embodiment, the server may derive an optimal translation path with the following algorithm.

Where A (i, j) is the translation accuracy between language i and language j, N is the number of languages, i-> j is a command to create an optimal translation path for translation from language i to language j , 1node is a command for calculating the translation accuracy R1 of the translation path which is a sequence of "language i-> language j", and 2node is the translation accuracy R2 of the translation path which is a sequence of "language i-> language k". 3node is a command for calculating the translation accuracy R3 of the translation path, which is a sequence of "language i-> language k-> language l-> language j". The server may determine a translation path corresponding to the largest translation accuracy among the translation accuracy of R1 to RM as an optimal translation path. The above algorithm is merely an example, and the server may derive an optimal translation path by employing algorithms such as dynamic programming and tree based optimal path search.

According to an embodiment of the present disclosure, the server may generate an optimal translation path based on not only the translation accuracy between languages belonging to the translation path but also translation time corresponding to the translation accuracy. The weights applied to the translation accuracy and the translation time may be variously modified according to the design intention.

Referring to FIG. 8, the server may generate translation paths for each text. The server may receive texts 801 of the input language. For example, the texts 801 may be divided into units such as sentences, phrases, and clauses. The server can recognize the complexity 802 corresponding to the texts 801. The server may recognize the complexity corresponding to the text based on the words included in the text, the number of words, the length of the text, the structure of the text, and the like. The complexity is the complexity of the processing required for translation, and can be expressed in units that represent discrete or continuous values.

The server may generate translation paths 803 corresponding to the complexity 802. The server may set the translation paths 803 differently depending on the complexity 802, where the translation accuracy and translation time recorded in the database may be taken into account.

The server may generate an optimal translation path based on the generated translation paths 803. The server may process translations of the texts 801 in parallel using the translation paths 803, and generate an optimal translation path for processing the translations in parallel based on the translation accuracy and translation time required. Can be.

Referring to FIG. 9, a server may translate text of an input language into texts of a target language through a plurality of translation paths, and receive feedback of a user regarding the translated texts. The server may receive the text of the input language and generate translation paths based on the translation accuracy and translation time. For example, the server may generate higher translation paths with higher translation accuracy. The server may translate and output the text of the input language into the texts 901 to 903 of the target language using the generated translation paths. The user may evaluate or select corresponding translation paths based on the output texts 901 to 903. The server may be fed back a selection result or evaluation result of any one of the texts 901 to 903 or a feedback or selection result of any one of translation paths corresponding to the texts 901 to 903. The server may determine a translation path selected from the user as an optimal translation path among translation paths corresponding to the texts 901 to 903 output from the user. The server may update the translation accuracy or translation time recorded in the database based on the feedback result by the user.
