     BACKGROUND OF THE DISCLOSURE 
     Information conversion refers to a process of converting one kind of information into another kind of information on the basis of ensuring that an original meaning is not changed, that is, converting source information into target information through information conversion technology. At present, commonly used information conversion technologies include: machine translation, for example, traditional statistical machine translation (SMT) and neural machine translation (NMT). In the process of information conversion through NMT, the input source information is usually encoded into a vector or a vector sequence, and then the target information is generated word by word based on the vector or the vector sequence obtained through encoding. 
     However, in the process of information conversion in the foregoing manner, a neural network model that has been trained is often used. If a conversion result needs to be adjusted, a training object needs to be reacquired, and the neural network model is trained again. In other words, the information conversion method provided by the related art has a problem of poor flexibility in information conversion due to a difficulty in using external resources and inability to add a new mapping relationship within a time required for information conversion during the information conversion. 
     For the foregoing problems, no effective solution has been proposed yet.

     DESCRIPTION OF EMBODIMENTS 
     To enable a person skilled in the art to better understand the solutions of the embodiments of this application, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings of the embodiments of this application. The described embodiments are merely some but not all of the embodiments of this application. All other embodiments obtained by persons skilled in the art based on the embodiments of this application shall fall within the protection scope of the embodiments of this application. 
     In the specification, claims, and accompanying drawings of this application, the terms “first”, “second”, and so on are intended to distinguish between similar objects rather than indicating a specific order. The data termed in such a way are interchangeable in proper circumstances, so that the embodiments of this application described herein can be implemented in other orders than the order illustrated or described herein. Moreover, the terms “include”, “contain” and any other variants mean to cover the non-exclusive inclusion, for example, a process, method, system, product, or device that includes a list of steps or units is not necessarily limited to those units, but may include other units not expressly listed or inherent to such a process, method, system, product, or device. 
     According to one aspect of the embodiments of this application, an information conversion method is provided. In this embodiment, the foregoing information conversion method may be applied to a hardware environment composed of a terminal  101  and a server  102  as shown in  FIG. 1 . As shown in  FIG. 1 , the terminal  101  is connected to the server  102  through a network. The network includes but is not limited to: a wide area network, a metropolitan area network, or a local area network. The terminal  101  may be a mobile terminal, or may be a PC terminal, a notebook terminal, or a tablet terminal. 
     The information conversion method may be applied to the server  102  or the terminal  101 . Generally, a conversion interface may be displayed on the terminal  101 . The terminal  101  sends to-be-converted source information received through the conversion interface to the server  102 . The server  102  converts the to-be-converted source information and returns a conversion result to the terminal  101 , and a conversion result is displayed on the conversion interface of the terminal  101 . The conversion interface may receive text information, voice information, or the like. The received voice information may be automatically converted into text and converted into target information as source information. 
       FIG. 2  is a flowchart of an information conversion method according to an embodiment of this application. For example, a server performs the information conversion method below. As shown in  FIG. 2 , the information conversion method can include the following steps. 
     In step S 202 , the server encodes source information to obtain a first code. 
     The server encodes the source information by using an encoder of a neural network to obtain the first code, the first code being a first vector. That is, the encoder of the neural network is configured to encode the source information into a set of vectors for representation. 
     In step S 204 , the server obtains a preset conversion condition. The conversion condition can be a mapping relationship between the source information and a conversion result. 
     The preset conversion condition may be a plurality of pieces of discontinuous information, the discontinuous information being used for indicating that a phrase includes at least two discontinuous parts with associations. For example, as a conversion condition, “an association with . . . ” is discontinuous information, including “an” and “association”, which are two discontinuous parts with associations. For example, let . . . go . . . take . . . is also a piece of discontinuous information, which may be used as a conversion condition, including the three associated but discontinuous parts of “let”, “go” and “take”. 
     The encoder of the neural network may also convert the source information without the conversion condition. However, target information obtained through conversion without using the conversion condition may be different from target information obtained through conversion by using the conversion condition. For example, the preset conversion condition is: “X and Y have a relationship-&gt;X has a relationship with Y”, where X and Y are variables and may be any segment. For example, “Beijing and Shanghai have a relationship” may be converted into “Beijing has a relationship with Shanghai” using this rule. However, when the rule is not used, “Beijing and Shanghai have a relationship” may be converted into “there is a relationship between Beijing and Shanghai”. 
     In other words, neural machine translation may also convert source information into target information according to logic without using the foregoing conversion condition. However, in order to make the conversion more accurate or make the converted information conform to the context and semantics of the source information, the conversion result may be made more accurate by adding the conversion condition. 
     For example, the word communication usually means an act of communicating. In the field of communication, the word is converted into correspondence and transmission. In the field of source information data communication, the neural machine translation may convert, according to the preset conversion condition, a phrase related to the word into a phrase of the communication field during the conversion, so that the conversion result is more accurate. The conversion may be language translation. 
     In step S 206 , the server decodes the first code according to the source information, the conversion condition, and translated information to obtain target information. The target information and the source information can be information in different languages. The translated information can be a word obtained through conversion of the source information. A language of the translated information can be the same as a language of the target information. 
     The source information may be Chinese, English, Japanese, Korean, Portuguese, Arabic and the like, and the target information may be Chinese, English, Japanese, Korean, Portuguese, Arabic and the like. The source information is converted into the target information in forms including but not limited to the following forms: Chinese is converted to any one of English, Japanese, Korean, Portuguese, and Arabic; English is converted to any one of Chinese, Japanese, Korean, Portuguese, and Arabic; Japanese is converted to any one of Chinese, English, Korean, Portuguese, and Arabic; Korean is converted to any one of Chinese, English, Japanese, Portuguese, and Arabic; Portuguese is converted to any one of Chinese, English, Japanese, Korean, and Arabic; and Arabic is converted to any one of Chinese, English, Japanese, Korean, and Portuguese. Other languages are converted in the same form as above, and the source information is converted into the target information of different languages, which are not individually described by using examples. 
     The process of converting source information into target information is a word-by-word conversion. The translated information is the word that is obtained through conversion of the source information and is a part of the source information that has been converted. Therefore, the language of the translated information is the same as the language of the target information. 
     The first vector is decoded according to the source information, the conversion condition, and the translated information by using a decoder of the neural network, to obtain target information, where the conversion condition is obtained in advance by the decoder of the neural network. That is, in the decoding process of the decoder of the neural network, the conversion condition is first obtained, and the first vector is decoded by combining the conversion condition, the source information, and the translated information. The conversion condition, translated information, and source information that are used for performing decoding are all in the form of vectors. The source information may be encoded into a vector through the encoder of the neural network. When the conversion condition is integrated into the neural machine conversion, the conversion condition needs to be encoded, which may be expressed in the form of continuous vectors. Generally, a recursive neural network may be used for encoding. However, the variable in the conversion condition may be treated as a general character for processing. These variables do not need special processing into special characters, and are encoded as vectors as general characters. 
     In this embodiment, the source information is converted by adding a conversion condition, the conversion condition can make the machine translation more flexible, and the conversion result is made more accurate through the conversion condition, thereby resolving the technical problem of poor flexibility of information conversion based on a neural network and achieving a technical effect of improving flexibility and accuracy. 
     An exemplary model for the neural machine translation is shown in  FIG. 3 , mainly including three modules. 
     (1) An encoder of a neural network encodes an input sentence as source information into a set of fixed vectors. 
     (2) A decoder of the neural network decodes an encoding result of the source information and generates a conversion result of target information step by step. 
     (3) A focusing mechanism, when decoding is performed, focuses attention on a source information segment most relevant to the current target information through the focusing mechanism. 
     In this embodiment, the step of conversion using the conversion condition is performed in the decoder of the neural network. Exemplary model is shown in  FIG. 4 . The phrase list in  FIG. 4  may include the foregoing preset conversion condition. 
     Optionally, the decoding the first code according to the source information, the conversion condition, and translated information, to obtain target information includes: determining a similarity in sentence patterns between a plurality of preset conditions and the source information according to the source information and the translated information; using a condition with a highest similarity in the plurality of conditions as the conversion condition; and decoding the first code according to the source information, the conversion condition, and the translated information, to obtain the target information. 
     A dictionary is input into the neural network. The dictionary includes a plurality of conditions such as discontinuous information and the like, and generally, there is a relatively large quantity of conditions. In the current conversion, all the conditions in the dictionary are not required, but some are selected for use from the majority of conditions in the dictionary. In this way, a condition required for the current conversion needs to be screened out from the large number of conditions in the dictionary, that is, a condition matching the current source information. For example, when a sentence “Beijing and Australia are related” is converted, a condition “X and Y are related” may be matched and left behind, but a condition “X defeats Y” is filtered out, so that conditions corresponding to each sentence are relatively limited. That is, a condition that is most similar to the source information in sentence patterns is found from a plurality of conditions as a conversion condition, to use the conversion condition in the current conversion. 
     Further, during decoding, the conditions in the dictionary are input to the decoder of the neural network, and the decoder dynamically selects the conversion conditions to be used through the focusing mechanism. The decoder selects the condition with a largest weight value as the conversion condition by obtaining a weight value of each condition. In the process of obtaining the weight value by the decoder of the neural network, the focusing mechanism is used. The focusing mechanism is to focus attention on source information most relevant to the current target information. For example, content most relevant to the current target information includes words (e.g., translated information) that have been converted before the current target information, source information and conditions that are related to the current target information. When the weight value is obtained, the weight value of each condition is determined according to the foregoing relevant source information, condition, and translated information. For example, the determining a similarity in sentence patterns between a plurality of preset conditions and the source information according to the source information and the translated information includes: determining a weight value of a first condition in the plurality of conditions according to a first vector for representing the source information, a second vector for representing the translated information, and a third vector for representing the first condition; and using a condition with a largest weight value as the condition with the highest similarity. 
     A neural network model is converted by using vectors. For example, all external input data is encoded into vectors for calculation. Therefore, the conditions in the dictionary need to be encoded into vectors and then input into the decoder of the neural network. 
     Optionally, the determining a weight value of a first condition in the plurality of conditions according to a first vector for representing the source information, a second vector for representing the translated information, and a third vector for representing the first condition includes: 
     obtaining a weight value a t  of the first condition by using the following formula; 
         a   t   =S ( Uh   t   +Ws   i ) 
     h t  representing a vector of a t th  condition, s i  representing the first vector and the second vector, S representing an S-shaped growth curve, U and W being matrices, respectively, and the first condition being any one of the plurality of conditions. 
     The S-shaped growth curve is sigmoid, and the two matrices U and W are multiplied by h t  and s i , respectively, to obtain two numbers, thereby obtaining the weight value of each condition expressed by numbers. The first condition is any one of the plurality of conditions. In this way, different conditions correspond to different weights. Because these weights are obtained through training and calculation, the neural network model will automatically learn conditions that are more important for the current conversion and determine that the current conversion needs higher weights. 
     With reference to  FIG. 4 , it may be learned that when the target information Y t  is obtained through conversion, the translated information Y t-1 , Y t-2 , . . . , and a plurality of conditions and source information X 1 , X 2 , . . . , X T  are also known. It may be learned from the foregoing formula that, a weight a t  of the current condition may be determined according to the second vector of the translated information, the third vector of the current condition, and the first vector of the source information. Then, rule information that is finally obtained is expressed as c t =Σ a t h i . According to weights of all conditions, the condition with the largest weight value may be determined, and the condition a t,T  with the largest weight value is used as the current condition to determine the currently translated word Y t . 
     It may be learned from  FIG. 4  that converted target information is determined each time by selecting the condition with the maximum weight value from the plurality of conditions. For example, when “Beijing and Shanghai are related” is converted, when the conversion of “Beijing has a relationship” has been completed, a condition with the maximum weight value is determined as “X and Y have a relationship-&gt;X has a relationship with Y” according to a vector of the source information of “Beijing and Shanghai are related”, a vector of the translated information “Beijing has a relationship” and a vector of each condition. Based on the condition, the current converted word is “with”, and then the next word is converted. According to the vector of the source information of “Beijing and Shanghai are related”, the vector of the translated information “Beijing has a relationship”, and the vector of each condition, the condition with the maximum weight value is determined as “X and Y are related-&gt;X has a relationship with Y”, and based on the condition, the current converted word is “Shanghai”. 
     According to this embodiment, since the weight of each condition may be determined according to the currently converted words, source information and conditions, the process of obtaining the weight is a process of automatic training and learning, so that the determined weight is more in line with the needs of the current word conversion. In combination with a corresponding condition, the word is converted into target information, so that the conversion result conforms to the context and field of the source information more accurately.
