Referring to fig. 3, fig. 3 is an optional flowchart of the method for processing the intelligent text in the vehicle-mounted environment according to the embodiment of the present invention, and it can be understood that the steps shown in fig. 3 may be executed by various electronic devices operating the apparatus for processing the intelligent text in the vehicle-mounted environment, for example, a dedicated terminal, an electronic device, or an electronic device cluster having a function of processing a search instruction. The following is a description of the steps shown in fig. 3.

Step 301: the vehicle-mounted environment intelligent text processing device acquires text content corresponding to selected operation in the touch screen.

When a user selects text information by using a touch screen electronic device (such as a vehicle central control device) due to the limitation of the operable area of the touch screen and the habit of one-hand operation of the user, the user cannot select an ideal text by manually controlling a cursor accurately, and the selection speed and the selection accuracy of the text by the user are affected. Therefore, the text processing model encapsulated in the intelligent text processing device in the vehicle-mounted environment can be used for acquiring text contents (long texts) corresponding to the selection operation in the touch screen to generate corresponding new target texts (short texts) for the user to select, and repeated text selection operation caused by selection errors of the user is avoided.

Step 302: and the vehicle-mounted environment intelligent text processing device extracts the characteristic vector matched with the text content.

In some embodiments of the present invention, extracting the feature vector matching the text content may be implemented by:

triggering a corresponding word segmentation library according to text parameter information carried by text content displayed in the touch screen; performing word segmentation processing on the text content displayed in the touch screen through the triggered word segmentation library word dictionary to form different word level feature vectors; and denoising the different word-level feature vectors to form a word-level feature vector set corresponding to the text content. Wherein, the word segmentation means that the meaning of verb also means the meaning of name word; each participle is a word or a phrase, namely the minimum semantic unit with definite meaning; for the received use environments of different users or different text processing models, the minimum semantic units contained in the received use environments need to be divided into different types, and adjustment needs to be made timely, and the process is called word segmentation, namely the word segmentation can refer to the process for dividing the minimum semantic units; on the other hand, the minimum semantic unit obtained after division is also often called word segmentation, that is, a word obtained after the word segmentation is performed; in order to distinguish the two meanings from each other, the smallest semantic unit referred to by the latter meaning is sometimes referred to as a participle object (Term); the term participled object is used in this application; the word segmentation object corresponds to a keyword which is used as an index basis in the inverted list. For Chinese, because words as the minimum semantic unit are often composed of different numbers of characters, and there are no natural distinguishing marks in alphabetic writing such as blank partitions and the like between the words, it is an important step for Chinese to accurately perform word segmentation to obtain reasonable word segmentation objects.

In conjunction with the foregoing step 301, different terminal devices (for example, the terminal 10-1 and/or the terminal 10-2 shown in the foregoing fig. 1) may provide text information for a user to read or use on respective corresponding touch screen display interfaces (for example, display interfaces of a web page, a dedicated APP, and a WeChat applet), and the user may process the displayed text information through the touch screen of the electronic device to select text information to be used, when the terminal device detects the click operation (or selection operation) on the text, the server is triggered to start a corresponding word segmentation instruction, the word segmentation instruction carries text parameter information carried by the text content to trigger a word segmentation library matched with the text content, the server receives the word segmentation instruction to execute corresponding operations to form different word-level feature vectors. Or when the terminal device displays different text information on a touch screen display interface, and when the click operation on the text information is detected, the terminal device sends the word segmentation instruction to the server, wherein the word segmentation instruction carries the word segmentation library matched with the current user (the word segmentation library carries a corresponding user identifier), and the server receives the word segmentation instruction to execute corresponding operation to form different word-level feature vectors. It should be noted that the embodiment of the present invention does not limit the triggering manner of the word segmentation instruction.

In some embodiments of the present invention, the language habits and the operation habits of different users are different, and different word segmentation methods need to be adjusted for different users to adapt to the language habits of different users. Especially for Chinese, the meaning unit is expressed based on Chinese characters, and the minimum semantic unit which really has a meaning is a word; because the space between words is not used as the segmentation like the space between English words, which words form words in a sentence of text is uncertain, and therefore, the word segmentation of Chinese texts is an important work. Moreover, for the text processing instruction text which contains things which are only valuable for natural language understanding, for the text processing model, it is necessary to determine which are really valuable search bases for searching relevant contents, so that a word-level feature vector set corresponding to the text processing instruction text can be formed by performing denoising processing on different word-level feature vectors as shown in step 302, and the occurrence of meaningless word-level feature vectors such as "yes", "ground" and "get" in the word-level feature vector set is avoided.

In some embodiments of the present invention, denoising the different word-level feature vectors to form a word-level feature vector set corresponding to the text content may be implemented by:

determining a dynamic noise threshold value matched with the use environment of the text processing model; denoising the different word-level feature vectors according to the dynamic noise threshold, and triggering a dynamic word segmentation strategy matched with the dynamic noise threshold; and performing word segmentation processing on the text content displayed in the touch screen according to a dynamic word segmentation strategy matched with the dynamic noise threshold value to form a dynamic word level feature vector set corresponding to the text content. Wherein, due to different use environments of the text processing model, the dynamic noise threshold matched with the use environment of the text processing model is different, for example, in the use environment of academic translation, the dynamic noise threshold matched with the use environment of the text processing model and only including the text information of the academic paper displayed by the terminal needs to be smaller than the dynamic noise threshold in the reading environment of the entertainment information text.

determining a fixed noise threshold corresponding to a usage environment of the text processing model;

denoising the different word-level feature vectors according to the fixed noise threshold, and triggering a fixed word segmentation strategy matched with the fixed noise threshold; and performing word segmentation processing on the target text according to a fixed word segmentation strategy matched with the fixed noise threshold, wherein a fixed word level feature vector set corresponding to the text content is obtained. When the text processing model is solidified in a corresponding hardware mechanism, such as a vehicle-mounted terminal or an intelligent medical system, and the using environment is professional term text information (or text information in a certain field), because the noise is relatively single, the processing speed of the text processing model can be effectively improved, the waiting time of a user is reduced, and the using experience of the user is improved through fixing a fixed noise threshold corresponding to the text processing model.

performing word segmentation processing on the text content displayed in the touch screen to form a word segmentation processing result; responding to the word segmentation processing result, and performing word deactivation processing on the text content to form text keywords matched with the text content; and determining a part-of-speech tagging result matched with the text content according to the text keywords matched with the text content, and forming a part-of-speech feature vector set corresponding to the text content. Because the text processed by the text processing model not only includes text information in a single language, but also may be complex text information in multiple languages (for example, a chinese-english hybrid academic paper as text information), in which, unlike english which directly uses spaces as intervals between words, for a chinese text, word segmentation is correspondingly required, because words in chinese can contain complete information. Correspondingly, a Chinese word segmentation tool Jieba can be used for segmenting Chinese texts. In addition, word processing needs to be stopped for the segmented keyword set correspondingly, and because words like "yes" and "can" have no information help for corresponding category labeling tasks. For example, for the text "yes, i'm favorite restaurant", the word segmentation and the word stop are performed to obtain a set of two keywords "favorite/restaurant" (using/as a separator, the same applies hereinafter), so that the processing speed of the text processing model can be effectively increased.

Referring to fig. 6, fig. 6 is an optional flowchart illustrating a text information processing method of a text processing model according to an embodiment of the present invention, and it can be understood that the steps shown in fig. 6 may be executed by various electronic devices of a text information processing apparatus running the text processing model, for example, a dedicated terminal, a server, or a server cluster having a text information processing function of the text processing model may be used to train the text information processing model to determine model parameters adapted to the text processing model, and specifically includes the following steps:

step 601: and the server acquires a training sample matched with the use environment of the text processing model.

In some embodiments of the present invention, obtaining training samples may be accomplished by:

detecting processing results of different users on the text content and corresponding operation parameters; forming historical data indexes respectively corresponding to the different users according to the processing result of the text content and the corresponding operation parameters; wherein the historical data index is used for evaluating the target text generated by the text processing model. Because the language habits and the operation requirements of different users are different, the processing results of the different users on the text content and the corresponding operation parameters can be detected, so that not only can a training sample for a certain user be obtained, but also the training samples of the different users can be fused to obtain a universal training sample set, and the universality of the text processing model can be trained.

Referring to fig. 7, fig. 7 is a schematic structural diagram of the intelligent text processing device 100 in the vehicle-mounted environment according to the embodiment of the present invention, which includes a blockchain network 200 (exemplarily illustrating the consensus node 210-1 to the consensus node 210-3), an authentication center 300, a service agent 400, and a service agent 500, which are respectively described below.

The type of blockchain network 200 is flexible and may be, for example, any of a public chain, a private chain, or a federation chain. Taking a public link as an example, electronic devices such as user terminals and servers of any service entity can access the blockchain network 200 without authorization; taking a federation chain as an example, an electronic device (e.g., a terminal/server) under the jurisdiction of a service entity after obtaining authorization may access the blockchain network 200, and at this time, become a client node in the blockchain network 200.

In some embodiments, the client node may act as a mere watcher of the blockchain network 200, i.e., provides functionality to support a business entity to initiate a transaction (e.g., for uplink storage of data or querying of data on a chain), and may be implemented by default or selectively (e.g., depending on the specific business requirements of the business entity) with respect to the functions of the consensus node 210 of the blockchain network 200, such as a ranking function, a consensus service, and an accounting function, etc. Therefore, the data and the service processing logic of the service subject can be migrated into the block chain network 200 to the maximum extent, and the credibility and traceability of the data and service processing process are realized through the block chain network 200.

Consensus nodes in blockchain network 200 receive transactions submitted from client nodes (e.g., client node 410 attributed to business entity 400, and client node 510 attributed to business entity 500, shown in fig. 7) of different business entities (e.g., business entity 400 and business entity 500, shown in fig. 7), perform the transactions to update the ledger or query the ledger, and various intermediate or final results of performing the transactions may be returned for display in the business entity's client nodes.

For example, the client node 410/510 may subscribe to events of interest in the blockchain network 200, such as transactions occurring in a particular organization/channel in the blockchain network 200, and the corresponding transaction notifications are pushed by the consensus node 210 to the client node 410/510, thereby triggering the corresponding business logic in the client node 410/510.

An exemplary application of the blockchain network is described below, taking an example in which a plurality of service entities access the blockchain network to implement management and processing of text information.

Referring to fig. 7, a plurality of business entities involved in the management link, such as a business entity 400, may be an artificial intelligence-based vehicle-mounted environment intelligent text processing device, a business entity 500 may be a display system with text display (operation) function, and registers from the certificate authority 300 to obtain respective digital certificates, each digital certificate includes a public key of the business entity and a digital signature signed by the certificate authority 300 on the public key and identity information of the business entity, and is used for being attached to a transaction together with the digital signature of the business entity for the transaction and sent to the blockchain network, for the blockchain network to take out the digital certificate and signature from the transaction, verify the authenticity of the message (i.e. whether it has not been tampered with) and the identity information of the service entity sending the message, and the blockchain network will verify according to the identity, for example whether it has the right to initiate the transaction. Clients running on electronic devices (e.g., terminals or servers) hosted by the business entity may request access from the blockchain network 200 to become client nodes.

The client node 410 of the service body 400 is configured to obtain text content corresponding to a selection operation in the touch screen; extracting a feature vector matched with the text content; determining at least one word-level hidden variable corresponding to the text content according to the feature vector through the text processing model; generating candidate words corresponding to the hidden variables of the word level and the selected probability of the candidate words according to the hidden variables of the at least one word level through the text processing model; selecting at least one candidate word to form a target text corresponding to the text content according to the selection probability of the candidate word and the historical behavior information of the corresponding target user; and displaying the target text in a display mode corresponding to the selected operation in the touch screen to realize the output of the target text, dividing the text content into different target texts to be matched with the operation of the user, and sending the text content and the corresponding target text matched with the text content to the blockchain network 200.

The text content and the generated target text are sent to the blockchain network 200, service logic may be set in the client node 410 in advance, when corresponding text information is formed, the client node 410 automatically sends the text content and the corresponding target text matched with the text content to the blockchain network 200, or a service person of the service agent 400 logs in the client node 410, manually packages the text content and the generated target text, and sends the text content and the generated target text to the blockchain network 200. Upon transmission, the client node 410 generates a transaction corresponding to the update operation based on the text content and the corresponding target text matching the text content, specifies in the transaction the smart contract that needs to be invoked to implement the update operation, and the parameters passed to the smart contract, and the transaction also carries the digital certificate of the client node 410, a signed digital signature (e.g., obtained by encrypting a digest of the transaction using a private key in the digital certificate of the client node 410), and broadcasts the transaction to the consensus node 210 in the blockchain network 200.

When the transaction is received in the consensus node 210 in the blockchain network 200, the digital certificate and the digital signature carried by the transaction are verified, after the verification is successful, whether the service agent 400 has the transaction right is determined according to the identity of the service agent 400 carried in the transaction, and the transaction fails due to any verification judgment of the digital signature and the right verification. After successful verification, node 210 signs its own digital signature (e.g., by encrypting the digest of the transaction using the private key of node 210-1) and continues to broadcast in blockchain network 200.

After receiving the transaction successfully verified, the consensus node 210 in the blockchain network 200 fills the transaction into a new block and broadcasts the new block. When a new block is broadcasted by the consensus node 210 in the block chain network 200, performing a consensus process on the new block, if the consensus is successful, adding the new block to the tail of the block chain stored in the new block, updating the state database according to a transaction result, and executing a transaction in the new block: and adding a key value pair comprising the text content and the corresponding target text matched with the text content into the state database for the transaction of submitting the updated text content and the corresponding target text matched with the text content.

A service person of the service agent 500 logs in the client node 510, inputs a text content or text information query request, the client node 510 generates a transaction corresponding to an update operation/query operation according to the text content or text information query request, specifies an intelligent contract that needs to be called to implement the update operation/query operation and parameters transferred to the intelligent contract in the transaction, and broadcasts the transaction to the consensus node 210 in the blockchain network 200, where the transaction also carries a digital certificate of the client node 510 and a signed digital signature (for example, a digest of the transaction is encrypted by using a private key in the digital certificate of the client node 510).

After receiving the transaction in the consensus node 210 in the blockchain network 200, verifying the transaction, filling the block and making the consensus consistent, adding the filled new block to the tail of the blockchain stored in the new block, updating the state database according to the transaction result, and executing the transaction in the new block: updating a key value pair corresponding to a certain text content in a state database according to different target texts for submitted transactions for updating the text content of the certain text and the corresponding target text matched with the text content; and for the submitted transaction for inquiring certain text content, inquiring the key value pair corresponding to the text content from the state database, and returning a transaction result.

It should be noted that fig. 7 exemplarily shows a process of linking the text content directly with the generated target text, but in other embodiments, for a case where the data size of the text content is large, the client node 410 may link the hash of the text content and the corresponding hash of the text information in pairs, and store the original text content and the corresponding target text information in a distributed file system or a database. After the client node 510 obtains the text content and the corresponding target text information from the distributed file system or the database, it may perform verification by combining with the corresponding hash in the blockchain network 200, thereby reducing the workload of uplink operation.

As an example of a block chain, referring to fig. 8, fig. 8 is a schematic structural diagram of a block chain in a block chain network 200 according to an embodiment of the present invention, where a header of each block may include hash values of all transactions in the block and also include hash values of all transactions in a previous block, a record of a newly generated transaction is filled in the block and is added to a tail of the block chain after being identified by nodes in the block chain network, so as to form a chain growth, and a chain structure based on hash values between blocks ensures tamper resistance and forgery prevention of transactions in the block. The text content stored in the blockchain network may be a dedicated text in a certain field (for example, case information of a medical system or experimental information data text in a scientific experiment), and sharing of the text content among different nodes may be achieved by storing the text content in the blockchain network.

An exemplary functional architecture of a block chain network provided in the embodiment of the present invention is described below, referring to fig. 9, fig. 9 is a functional architecture schematic diagram of a block chain network 200 provided in the embodiment of the present invention, which includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, which are described below respectively.

The method for processing the intelligent text in the vehicle-mounted environment provided by the embodiment of the present invention is described below by taking selection of text information in a touch screen of a vehicle-mounted terminal in the vehicle-mounted environment as an example, where fig. 10 is a schematic view of an application environment for text selection in the related art in the embodiment of the present invention, where the text can be selected only in a touch screen sensing manner in the related art as shown in fig. 10, specifically, in the using process of the scheme, a terminal receives a signal touched by a finger through the touch screen, positions a cursor according to a touch position, and a user can select a boundary of a corresponding text by using the cursor. In the process, the text can be selected only according to the position where the touch screen senses the finger touch, the target text is inconvenient to select when the text font is small, and meanwhile, because the user often easily selects the wrong text or selects the text characters in a missing mode through one-hand operation, the user can select the target text for many times, and the operation time of the user is wasted.

Further, fig. 11 is a schematic diagram of an application environment for text selection in the related art in the embodiment of the present invention, where in the related art, as shown in fig. 11, a text may be selected in a touch screen sensing manner, and a punctuation mark is considered, specifically, on the basis of the scheme shown in the foregoing fig. 10, when text information of a text to be selected is determined, a common character and the punctuation mark may be distinguished, because the punctuation mark is a boundary of a sentence or a half-sentence, when a cursor of a user moves to a vicinity of the punctuation mark, the system may use the punctuation mark as a boundary of a target text with a higher probability, but in this process, although the punctuation mark is considered in text selection, this process may only use the punctuation mark to perform auxiliary selection, and for a text in a sentence that the user wants to select, for example, a word in the sentence shown in fig. 11 cannot perform auxiliary selection. Meanwhile, personalized recommendation cannot be performed according to the historical habits of the users (for example, the users need to select texts including punctuations, and some users do not need to include texts of the punctuations), so that the personalized recommendation is not beneficial to different users.

Further, fig. 12 is a schematic diagram of an application environment for text selection in the related art in the embodiment of the present invention, and as shown in fig. 12, in the related art, a corresponding target text is selected in a touch screen sensing manner, and word segmentation processing is performed on the target text in consideration of word segmentation information. However, in this process, only word information can be used for auxiliary selection, and a longer phrase or short sentence cannot be selected, and meanwhile, this process cannot perform personalized recommendation according to the historical habits of the users (different users and different fields have different word segmentation processing methods).

Fig. 13 is a schematic diagram of a working process of the text processing model according to the embodiment of the present invention, which specifically includes the following steps:

step 1301: the server acquires text content displayed in a touch screen of the vehicle-mounted terminal;

step 1302: acquiring a selection operation in the touch screen, and extracting a characteristic vector matched with text content displayed in the touch screen in response to the selection operation;

due to the limitation of the operable area of the vehicle-mounted touch screen and the habit of single-hand operation of a user, the user does not have time and energy to accurately select, so that the text selected by the user manually controlling the cursor is not accurate, an ideal text in the vehicle-mounted touch screen cannot be selected frequently, and the operation in the touch screen selection can trigger the text processing model to determine a corresponding target text by double-clicking the vehicle-mounted touch screen by the user without the accurate selection and control of the user.

Step 1303: at least one word-level hidden variable corresponding to the text content is determined by an encoder of the text processing model.

Of course, the text processing model needs to be trained before the text processing model processes the text content to determine the corresponding network parameters.

With continuing reference to fig. 14A and 14B, fig. 14A is a schematic diagram of text selection of a text processing model provided in the embodiment of the present invention, and fig. 14B is a schematic diagram of a training process of the text processing model provided in the embodiment of the present invention, which specifically includes the following steps:

First, the user may provide one or more touches to the screen to select text, and then select the target text followed by further operations (e.g., copy, send, etc.). The text selected by the user before the next operation can be regarded as the real target text of the user. Meanwhile, the position of the finger when the user touches the screen is recorded. Of course, to distinguish between different users, the users are configured with an ID (not repeated from each other) when recording the training data, and each sample indicates the user ID. In combination with the preamble embodiment, for different vehicle-mounted terminals of the same target user, the server may obtain training samples matched with the target user from the corresponding block chain network, and train the text processing model.

Step 1402: and extracting various characteristics of the training sample through a characteristic extractor, and inputting the characteristics into a text processing model.

The extracted features comprise word segmentation (the ID is used for indicating that the word change belongs to the number of words), part of speech tagging, word vectors, entity recognition and semantic role analysis (tagged main/predicate/object). Fig. 15A is a data structure diagram of the text processing model in the embodiment of the present invention, and fig. 15B is a data structure diagram of the text processing model in the embodiment of the present invention, each feature is extracted by one feature extractor, and the extracted features can be represented in the form of floating point vectors.

Step 1403: and inputting the floating point vector into a recurrent neural network model, and predicting a final result through the recurrent neural network.

In this process, the encoder parameters and decoder parameters of the text processing model are iteratively updated until a corresponding convergence function is reached.

Step 1404: and finishing the training of the text processing model.

In some embodiments of the present invention, the text processing model provided by the present invention may include two sub-models, respectively: the method comprises a global user text processing model and a current user text processing model, wherein data of all users can be used as training samples for training the global user text processing model, and only data of the current user is used as the training samples in the training of the current user text processing model so as to improve the pertinence of the model.

Step 1304: generating, by a decoder of the text processing model, a candidate word corresponding to the word-level hidden variable and a selected probability of the candidate word according to the at least one word-level hidden variable;

step 1305: and selecting at least one candidate word to form a processing result corresponding to the text content according to the selection probability of the candidate word and the historical behavior information of the corresponding target user.

Step 1306: and outputting short text sentences or words to a display interface of the vehicle-mounted terminal so as to predict the target text to be selected by the user.

Therefore, compared with the traditional technology for processing the text in the touch screen, according to the technical scheme provided by the application, the text processing model is triggered by detecting the operation of the user on the touch screen, the text to be selected by the user can be predicted only through the selection operation of the target user, the accuracy of user selection is improved, the smoothness of user use is improved, meanwhile, the operation steps of the user on the text information in the touch screen under the environment of the vehicle are reduced, and therefore the use experience of the user is effectively improved.

The beneficial technical effects are as follows:

acquiring text content corresponding to selection operation in a touch screen; extracting a feature vector matched with the text content; determining at least one word-level hidden variable corresponding to the text content according to the feature vector through the text processing model; generating candidate words corresponding to the hidden variables of the word level and the selected probability of the candidate words according to the hidden variables of the at least one word level through the text processing model; selecting at least one candidate word to form a target text corresponding to the text content according to the selection probability of the candidate word and the historical behavior information of the corresponding target user; and displaying the target text in a display mode corresponding to the selection operation in the touch screen, so that in the process of selecting the text by using the vehicle on the environmental touch screen by a user, the target text to be selected by the user can be judged in advance through the corresponding text processing model, and the corresponding target text is output for the user to select, so that the text processing model can generate the high-quality target text, repeated selection operation caused by selection errors of the user is reduced, and the use experience of the user is improved.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
