If the first user finds that an error (for example, a wrongly written word or a homophone) exists in the sent first session information, responding to a triggering operation of the first user in the current social chat interface, the first user equipment sends a modification request to the network equipment to request to modify the first session information, the network equipment detects whether read information about the first session information sent by the second user equipment is received or not in real time, if the read information is not received, the network equipment sends an instruction for granting modification to the first user equipment in response to the modification request, the first user equipment presents the first session information in a dialog box of the social chat interface for the first user to modify based on the instruction, the first user modifies based on the first session information to generate second session information, and on the basis of the second session information, the network equipment receives the modification request sent by the first user equipment again, and sending the second session information in the modification request to the second user equipment so that the second user equipment can superimpose the second session information on the first session information, thereby hiding the first session information. And when the second user opens the social chat interface of the social application, the second user equipment presents the second session information to the second user, wherein the first user equipment is used for providing the second session information. The second user device includes, but is not limited to, a computing device (with a touch screen) such as a cell phone, tablet, and laptop.

Fig. 2 shows a method for sending session information in a social application, applied to a network device, according to an embodiment of the present application, where the method includes step S101, step S102, and step S103.

Specifically, in step S101, the network device receives first session information sent by the first user device in response to a trigger event in a session interface of the social application, and sends the first session information to the second user device. For example, a social application is installed in a first user device, the first user device presents a session interface of the social application, a first user inputs first session information in an input box in the session interface, where the first session information includes character information (e.g., text information, symbol information), expression information, and the like, the session interface is the session interface of the first user and a second user, the first user clicks a send button of the second user in the session interface to generate a trigger event, the first user device sends the first session information to a network device, and the network device sends the first session information to the second user device. In some embodiments, the session interface includes a chat interface between the first user and another user (e.g., one or more) and the second user device is any one of the other users (user a, user B, user C …), and it is not limited to that the first session information is viewed by any one user in the session interface as long as the first session information is viewed by any one user in the session interface when the subsequent network device detects the reading state of the first session information.

In step S102, after the first session information is successfully sent, the network device detects whether the first session information has an area to be modified, if so, detects a reading state of the first session information, and if the reading state includes that the first session information is not checked by a second user, modifies the first session information into second session information. For example, the second user device has received the first session information, and after that, the network device actively recognizes whether there is an error in the first session information, for example, there is a word error in the first session information (e.g., the first user originally sends "your son is old this year", but last sends "your word is old this year", for example, the first user originally sends "i is sick, coughed for several days", but finally sends "i is sick, coughed for several days" to the second user), or there is a semantic error, which causes the whole text table to be unclear (e.g., the first user originally sends "i wants to detect whether this application really has a teaching function", but last sends "i wants to detect whether this application really has a correction function"), a harmony word (e.g., a pair of eyes-glasses), a pair of eyes-glasses, a pair of eyes-glasses, confusing sound words (e.g., wandering girl-cowshed girl), word order reversal (e.g., wood-allen-alenwood), word completion (e.g., love-if love is happy), grammatical errors (e.g., imagine difficult-imagine), etc., the network device may employ some text error correction algorithms (e.g., wrongly written word dictionary, edit distance, language model (ngram LM, DNN LM, word-based model), etc.) to identify whether there are regions in the first session information that need to be modified, e.g., the first session information is not all-segment-word error, possibly partial error (e.g., beginning, middle segment, or end of the entire segment). If the first session information has an error, the network device acquires the reading state of the first session information in real time, and if the current reading state includes that the first session information is not viewed by the second user, the network device determines that the first session information can be modified under the condition that the second user does not sense, and modifies the first session information into the second session information based on a text error correction algorithm (for example, the first session information can be participled first and then fuzzy matching is adopted). In some embodiments, in step S102, after the first session information is successfully sent, the network device detects whether the first session information has a to-be-modified area, if so, detects a reading state of the first session information, and if the reading state includes that the first session information is not checked by a second user, obtains one or more pieces of to-be-modified information in the to-be-modified area, and performs modification on each piece of to-be-modified information to generate modified information; and generating second session information according to the correction information of each section and the first session information. For example, the network device detects that the area to be modified in the first session information is one or more, for example, the first session information is "we start to rain the AAAA at this point, the AAAAA is estimated to occur after a while, then, we wait for the aaaaaaaa" network device to determine that the first session information includes 3 segments of areas to be modified, which are AAAA, AAAAA, and AAAAAA, respectively, and the network device only needs to modify the three segments without modifying all of the first session information, thereby improving the efficiency of information modification, and certainly combining corresponding context information for the three segments of areas to be modified. For example, the network device modifies the three segments into AAAA ', AAAAA ', and aaaaaaaa ', respectively, and then generates the second session information by combining the first session information and replacing the three segments with the three segments of the area to be modified in the first session information.

In step S103, the network device sends the second session information to the second user device, where the second session information is used to replace the location of the first session information in the second user device, or the second session information is used to be superimposed on the location of the first session information in the second user device. On the basis of the modification of the second session information, the network device can send the second session information to the second user device under the condition that the second user does not perceive the second session information so as to replace the first session information to be presented in a session interface of the second user device. For example, after receiving the second session information, the second user equipment hides the first session information and superimposes the second session information on the first session information, or the second user equipment cancels the first session information and replaces the second session information for presentation. In some embodiments, in order to make the information that is seen by the first user and the second user finally opening the social application consistent and not misunderstood, after the second session information is successfully replaced by the first session information at the second user equipment, the network device sends the second session information to the first user equipment so as to replace the first session information presented in the first user equipment by the second session information, and the network device may notify the first user of the replacement of the information so as to improve user experience.

In some embodiments, in step S102, after the first session information is successfully sent, the network device detects whether there is an area to be modified in the first session information, if so, detects a reading status of the first session information, and if the reading status includes that the first session information is not viewed by a second user, performs modification of the first session information into second session information, and sends modification inquiry information to the first user device, where the modification inquiry information includes modification of the first session information into the second session information; in step S103, the network device receives feedback information returned by the first user device based on the modification inquiry information, and sends the second session information to the second user device if the feedback information includes an agreement to modify, where the second session information is used to replace the location of the first session information in the second user device, or the second session information is used to be superimposed on the location of the first session information in the second user device. For example, on the basis that the network device determines that the first session information needs to be modified and the current first session information is not viewed, the network device modifies the first session information into second session information by itself, and first sends the modification result to the first user device to inquire whether the first user device agrees with the modification, if the modification meets the meaning intended by the first user or the first user agrees with the modification, the first user device sends feedback information agreeing with the modification to the network device based on the modification inquiry information, so that the network device subsequently sends the second session information to the second user device based on the feedback information, in some embodiments, if the first user disagrees with the modification, the network device ignores the second session information and stops continuing the modification, in some embodiments, after receiving the modification inquiry information by the first user device, the feedback information of the first user may be sent according to the modification of the network device, for example, the feedback information includes a result of the first user performing the re-modification based on the modification of the network device, and the network device may send the result of the first user performing the re-modification to the second user device based on the feedback information to be presented to the second user as the second session information instead of the first session information.

In some embodiments, in step S103, the network device continues to detect a reading status of the first session information, and if the reading status includes that the first session information has been viewed by a second user, sends the second session information to the second user device, and sends a message update prompt to the second user device, where the second session information is used to replace a location of the first session information in the second user device, or the second session information is used to be superimposed on a location of the first session information in the second user device. For example, after the first session information is successfully sent, the network device detects the reading state of the first session information in time, when the first session information is not checked by the second user, the network device modifies the first session information into the second session information, after the network device successfully modifies the first session information and before the first session information is not sent to the second user device, the network device continues to detect the reading state of the first session information to determine whether the first session information is checked by the second user, and if so, after the network device sends the second session information to the second user device, the network device sends a message update prompt (for example, the first session information "AAAAAA" has been updated to the second session information "AAAAAAA", please check in time) and timely prompts the second user to check the updated first session information. And after the second user opens the current session interface, replacing the position originally presenting the first session information in the second user equipment with the second session information.

In some embodiments, the method further includes step S104 (not shown), in step S104, the network device continues to detect the reading status of the first session information in the process of modifying the first session information into the second session information; in step S103, if the reading status includes that the first session information has been viewed by a second user, the network device sends the second session information to the second user device, and sends a message update prompt to the second user device, where the second session information is used to replace a location of the first session information in the second user device, or the second session information is used to be superimposed on a location of the first session information in the second user device, and the message update prompt includes the second session information. For example, after the first session information is successfully sent, the network device detects a reading state of the first session information in time, when the first session information is not viewed by the second user, the network device modifies the first session information into the second session information, in the process of modifying the first session information into the second session information, if the network device detects that the first session information is viewed by the second user in the process of continuing detection, after the first session information is modified into the second session information, the network device sends the second session information to the second user device, and the network device sends a message update prompt (for example, the first session information "AAAAAA" is updated into the second session information "AAAAAAA", and requests to view in time) and timely prompts the second user to view the updated first session information. And after the second user opens the current session interface, replacing the position originally presenting the first session information in the second user equipment with the second session information.

In some embodiments, the method further includes step S105 (not shown), in step S105, the network device continues to detect a reading status of the first session information during the process of modifying the first session information into the second session information, and if the reading status includes that the first session information is already viewed by the second user, cancels the modifying of the first session information into the second session information, and sends a modification prompt message to the first user device, where the modification prompt message includes that the modifying of the first session information is prohibited. For example, after the first session information is successfully sent, the network device detects the reading state of the first session information in time, when the first session information is not viewed by the second user, the first session information is modified into the second session information, and in the process of modifying the first session information into the second session information, if the network device detects that the first session information is viewed by the second user in the process of continuing detection, the network device cancels the execution of modifying the first session information into the second session information for the user experience consideration of the second user, and still keeps presenting the first session information to the second user.

In some embodiments, the method further includes step S107 (not shown), and in step S107, if the reading status includes that the first session information has been viewed by the second user, the network device ignores the modification request regarding the first session information. For example, even if the network device detects that there is a place where the sent first session information needs to be modified, in the case that the reading state includes that the first session information has been viewed by the second user, the network device does not make any modification to the first session information in order not to disturb the session information for the second user, and rejects the modification request of the other users (e.g., the sending user of the first session information) about the first session information.

In some embodiments, the method further includes step S106 (not shown), in step S106, if the reading status includes that the first session information has been viewed by the second user, the network device performs modifying the first session information into second session information, and sends first modified inquiry information to the first user device, where the first modified inquiry information includes modifying the first session information into the second session information; and receiving feedback information returned by the first user equipment based on the modification inquiry information, if the feedback information includes the modification agreement, sending the second session information to the second user equipment, and sending a message update prompt to the second user equipment, wherein the second session information is used for replacing the position of the first session information in the second user equipment, or the second session information is used for being superposed and presented at the position of the first session information in the second user equipment, and the message update prompt includes the second session information. For example, where the network device detects that there is a first session information that needs to be modified, even if the reading status includes that the first session information has been viewed by the second user, the network device performs modification of the first session information into the second session information, in order to make the modification of the network device conform to the intention of the transmitting user of the first session information, the network device self-modifies the first session information into the second session information and first transmits the modification result to the first user device to inquire whether the first user agrees with the modification, if the modification conforms to the intention intended by the first user or the first user agrees with the modification, the first user device transmits feedback information agreeing with the modification to the network device based on the modification inquiry information, so that the network device subsequently transmits the second session information to the second user device based on the feedback information, and after the second session information is received by the second user device, the network device sends an information update reminder (for example, a pop-up window is used for prompting when the second user does not open the social application) about the first session information to the second user, so that the second user can view the update content in time. In some embodiments, if the first user does not agree with the aforementioned modification, the network device ignores the second session information, and in some embodiments, after receiving the modification solicitation information, the first user device may send feedback information of the first user according to the modification of the network device, where, for example, the feedback information includes a result of the first user performing the re-modification based on the modification of the network device, and the network device may send the result of the first user performing the re-modification to the second user device based on the feedback information, so as to present the second session information to the second user in place of the first session information.

In some embodiments, the detecting the reading state of the first session information comprises: receiving mark field information about the first session information sent by the second user equipment in real time, and if the mark field information is a first field, determining that the reading state includes that the first session information is viewed by the second user; otherwise, determining that the reading status includes that the first session information is not viewed by the second user. For example, for all session information received by the second user equipment, the second user equipment marks each session information, for example, each session information is configured with flag field information, and if the flag field information is a first field (for example, 1), it is determined that the reading state includes that the first session information has been viewed by the second user; if the flag field information is a second field (e.g., 0), determining that the reading status includes that the first session information is not viewed by the second user. For another example, the second user device stores the IDs of the unread messages in all the received session messages in a second user table of the network device, and requests the network device to delete the corresponding IDs when the session messages exist, and the network device detects whether the first session messages exist according to the data in the user table, and if so, determines that the first session messages are not checked by the second user.

In some embodiments, in step S101, the network device receives candidate first session information sent by the first user equipment in response to a trigger event in a session interface of the social application, detects whether the candidate first session information has an area to be modified, and if so, modifies the candidate first session information into the first session information; and sending the first session information to a second user equipment. For example, after the network device receives candidate first session information sent by a first user, the network device does not send the candidate first session information to a second user device at this time, if the network device detects the candidate first session information in advance to determine whether an area to be modified exists, and modifies the candidate first session information into the first session information when an error is detected, and sends the first session information to the second user device, that is, the information sent by the first user is detected and modified in advance, even if the first session information is detected again after being sent, at this time, the portion of the network device that needs to be modified is greatly reduced, and the subsequent processing efficiency of the network device can be improved.

Referring to the system shown in fig. 1, fig. 3 shows a system method for sending session information in a social application according to an embodiment of the present application, the method comprising:

the network device receives the second modification request, sends the second session information to the second user device in response to the second modification request, and returns modification feedback information to the first user device, wherein the second session information is used for replacing the position of the first session information in the second user device, or the second session information is used for being superposed and presented at the position of the first session information in the second user device;

Fig. 4 shows a method for sending session information in a social application, applied to a network device, according to an embodiment of the present application, where the method includes step S201, step S202, step S203, and step S204.

Specifically, in step S201, the network device receives first session information sent by the first user device in response to a first trigger event in a session interface of the social application, and sends the first session information to the second user device. For example, a social application is installed in a first user device, the first user device presents a session interface of the social application, a first user inputs first session information in an input box in the session interface, where the first session information includes character information (e.g., text information, symbol information), expression information, and the like, the session interface is the session interface of the first user and a second user, the first user clicks a send button of the second user in the session interface to generate a first trigger event, the first user device sends the first session information to a network device, and the network device sends the first session information to the second user device. In some embodiments, the session interface includes a chat interface between the first user and another user (e.g., one or more) and the second user device is any one of the other users (user a, user B, user C …), and it is not limited to that the first session information is viewed by any one user in the session interface as long as the first session information is viewed by any one user in the session interface when the subsequent network device detects the reading state of the first session information.

In step S202, the network device receives a first modification request sent by the first user device in response to a second trigger event in the social application, detects a reading status of the first session information in response to the first modification request, and returns modification instruction information to the first user device if the reading status includes that the first session information is not viewed by a second user, where the modification instruction information includes permission for modification, and the first modification request includes identification information of the first session information. For example, a button is present in the session interface of the first user equipment, the button has a function for requesting the first user to modify the sent session information, in response to the triggering operation of the button by the first user, the first user equipment generates a second triggering event, and sends a first modification request to the network equipment based on the second triggering event, wherein the first modification request is used for requesting to acquire the right to modify the first session information, the network device responds to the first modification request, detects whether the first session information is viewed by the second user, if the first session information is not viewed, the network device determines that the first session information can be replaced subsequently without the perception of the second user, and sending the content which the first user wants to modify to the second user equipment, wherein the network equipment agrees that the first user obtains the modification authority about the first session information and returns modification instruction information allowing modification to the first user equipment. For another example, in response to a triggering operation (e.g., a revocation operation) by the first user on the first session information in the session interface, the first user device generates a second triggering event and sends a first modification request to the network device based on the event, the network device returns an instruction to allow modification to the first user if the first session information is not viewed by the second user based on the first modification request, and performs a revocation operation (e.g., hides the first session information) on the first session information in the second user device to send content that the first user wants to modify to the second user device subsequently without the second user's perception.

In step S203, the network device receives a second modification request sent by the first user device in response to the modification instruction information, where the second modification request includes second session information, and the second session information is generated after the first user edits the first session information. For example, after the first user equipment receives the modification instruction information allowing modification, the first user equipment directly presents the first session information in a chat input box of a session interface of the first user equipment, the first user does not need to re-input the whole segment, the first user equipment directly modifies the first session information on the basis of the first session information, and after the first user finishes modifying the first session information, the first user equipment sends a second modification request to the network equipment in response to a re-triggering operation of the first user (for example, clicking a button after the modification is finished to send the modified first session information, that is, the second session information), and the second modification request is used for replacing the sent first session information with the second session information.

In step S204, the network device sends the second session information to the second user equipment in response to the second modification request, and returns modification feedback information to the first user equipment, where the second session information is used to replace the position of the first session information in the second user equipment, or the second session information is used to be superimposed on the position of the first session information in the second user equipment. For example, the network device sends the second session information to the second user device under the condition that the second user is unaware (that is, under the condition that the page where the first session information is located is not viewed), so that the second user device hides the first session information after receiving the second session information, and superimposes the second session information on the first session information, or the second user device withdraws the first session information, and replaces the second session information to present the second session information. In some embodiments, in order to make the information that the first user and the second user finally open the social application to see consistent and not misunderstood, the first user device prepares to replace the first session information displayed in the first user device with the second session information when sending the second modification request. And after the network equipment successfully sends the second session information, returning the successfully modified information to the first user equipment, so that the second session information is also presented in the first user equipment.

For example, the first user enters the conversation information "we start raining at this point, and estimate that we stop after a while, and then we wait for the raining to come out of a party bar" in the chat input box of the conversation interface and send the information to the users in the conversation interface. The first user detects that the sent information has an error (for example, the first user wants to send snow), and then requests to the network device for modification, the network device responds to the request to detect that no user exists in a group corresponding to the conversation interface to view the conversation information, and agrees with the modification request of the first user, the first user device presents in an input box of the conversation interface that "the user starts to rain right now and stops in a certain time, then the user waits for the rain and then comes out of a party for the first user to modify," the first user modifies the first user to "the user starts to snow right now and stops in a certain time, then the user waits for the snow to stop and then comes out of a party", and sends the modified information to the network device, the network device replaces the modified information with "the user starts to rain right now and then estimates that the user stops in a certain time, and then, the user who gets out of the party bar after raining is presented with the information, and after the network equipment successfully sends the modified information, the modified information sent by the first user is presented in the session interface of the first user.

In some embodiments, the method further includes, before step S203, step S205 (not shown), in step S205, the network device continues to detect a reading status of the first session information; in step S203, if the reading status includes that the first session information has been viewed by the second user, the network device receives a second modification request sent by the first user device in response to the modification instruction information, where the second modification request includes second session information, and the second session information is generated after the first user edits the first session information; in step S204, the network device sends the second session information to the second user equipment in response to the second modification request, sends a message update prompt to the second user equipment, and returns modification feedback information to the first user equipment, where the second session information is used to replace the location of the first session information in the second user equipment, or the second session information is used to be superimposed on the location of the first session information in the second user equipment, and the message update prompt includes the second session information. For example, when the network device allows the first user to modify the first session information, during the modification of the first session information by the first user, the network device continuously detects the reading status of the first session information, and if it is detected that the second user has viewed the first session information during the modification of the first session information, the network device may still receive the second modification request sent by the first user device, and send the second session information to the second user device based on the second modification request, only if the session information is changed, the network device immediately reminds the second user that the first session information has been modified (e.g., the first session information "AAAAAA" has been updated to the second session information "aaaaaaaaa", please view in time) on the premise that the second user has viewed the first session information.

In some embodiments, the method further includes, before step S203, step S206 (not shown), in step S206, the network device continues to detect the reading status of the first session information; in step S203, if the reading status includes that the first session information has been viewed by the second user, the network device ignores a second modification request sent by the first user device in response to the modification instruction information, where the second modification request includes second session information, and the second session information is generated after the first user edits the first session information; in step S204, the network device returns modification feedback information to the first user equipment, where the modification feedback information includes a modification failure. For example, in the process that the network device allows the first user to modify the first session information, the network device continuously detects the reading state of the first session information during the process that the first user modifies the first session information, if it is detected that the second user has viewed the first session information during the process that the first session information is modified, in order to prevent confusion of information acquired by the second user, the network device determines not to modify the first session information, wherein the network device ignores a second modification request sent by the first user device for modifying the first session information, and returns modification feedback information which fails to modify or prohibits modification to the first user device so as to prompt the first user that the first session information still remains and cannot be modified.

In some embodiments, the method further includes step S207 (not shown), in step S207, if the reading status includes that the first session information has been viewed by the second user, the network device returns modification instruction information to the first user device, where the modification instruction information includes prohibition of modification. For example, after the network device sends the first session information to the second user device, the network device detects that the first session information has been viewed by the second user in response to the first modification request, based on which the network device determines that the first user is prohibited from modifying the first session information in order not to make it overly and cumbersome for the second user to obtain information, and keeps the first session information subsequently presented to the second user.

Fig. 5 shows a method for sending session information in a social application, applied to a first user equipment, according to an embodiment of the present application, where the method includes step S301, step S302, step S303, step S304, and step S305.

Specifically, in step S301, in response to a first trigger event in a session interface of a social application, a first user device sends first session information input by a first user to a network device corresponding to the social application, where the network device is configured to send the first session information to a second user device. For example, a social application is installed in a first user device, the first user device presents a session interface of the social application, a first user inputs first session information in an input box in the session interface, where the first session information includes character information (e.g., text information, symbol information), emotion information, and the like, the session interface is a session interface of the first user and a second user, the first user clicks a send button of the second user in the session interface to generate a first trigger event, and the first user device sends the first session information to the network device.

In step S302, after the first session information is successfully sent, the first user equipment sends a first modification request about the first session information to the network device in response to a second trigger event in the social application, where the first modification request includes identification information of the first session information. For example, a button is present in the session interface of the first user equipment, the button has a function for requesting the first user to modify the sent session information, in response to the triggering operation of the button by the first user, the first user equipment generates a second triggering event, and sends a first modification request to the network equipment based on the second triggering event, wherein the first modification request is used for requesting to acquire the right to modify the first session information, and for example, in response to a triggering operation (e.g., a withdrawing operation) of the first user on the first session information in the session interface, the first user equipment generates a second triggering event and sends the first modification request to the network device based on the event, to request the network device to withdraw the first session information sent to the second user device and obtain the right to modify based on the first session information (e.g., withdraw the content of the first session information back into the input box of the first user device for modification).

In step S303, the first user equipment receives modification instruction information returned by the network device in response to the first modification request, and if the modification instruction information includes permission to modify, modifies the first session information into second session information. For example, the network device responds to the first modification request, detects whether the first session information is already viewed by the second user, if not, the network device determines that the first session information can be replaced subsequently without perception of the second user, and sends the content which the first user wants to modify to the second user device, and the network device agrees that the first user obtains modification authority about the first session information and returns modification instruction information allowing modification to the first user device.

In step S304, the first user equipment sends a second modification request to the network device, where the second modification request includes second session information. For example, after the first user equipment receives the modification instruction information allowing modification, the first user equipment directly presents the first session information in a chat input box of a session interface of the first user equipment, the first user does not need to re-input the whole segment, the first user equipment directly modifies the first session information on the basis of the first session information, and after the first user finishes modifying the first session information, the first user equipment sends a second modification request to the network equipment in response to a re-triggering operation of the first user (for example, clicking a button to send the modified first session information, that is, the second session information after the modification is finished).

In step S305, the first user equipment receives modification feedback information returned by the network device in response to the second modification request, and if the modification feedback information includes a modification success, the second session information is presented in the session interface. For example, the network device sends the second session information to the second user device under the condition that the second user is unaware of (i.e. under the condition that the page where the first session information is located is not viewed), where the first user is modified successfully, and the network device sends the modification feedback information that is modified successfully to the first user device. In some embodiments, in step S305, the first user equipment receives modification feedback information returned by the network device in response to the second modification request, where the modification feedback information includes a modification failure. If the network equipment detects that the reading state comprises that the first session information is viewed by the second user in the process of modifying the first session information by the first user, the network equipment returns modification instruction information for prohibiting modification to the first user equipment, so that the second user is not disturbed by the existence of the modified session information.

In some embodiments, the method further includes step S306 (not shown), in step S306, the first user equipment receives modification instruction information returned by the network device in response to the first modification request, and ignores the second modification request if the modification instruction information includes prohibition of modification. For example, if the network device detects that the reading state includes that the first session information has been viewed by the second user, in order not to interfere with the second user, the network device returns modification instruction information for prohibiting modification to the first user device, and does not process a subsequent request sent by the first user device for modifying the first session information.

In some embodiments, in step S301, in response to a first trigger event in a session interface of a social application, a first user equipment detects whether a candidate first session information input by a first user in the first trigger event has a text region to be modified, and if so, presents the text region to be modified, where the text region to be modified includes text to be modified, recommended modified text, and modification identification information; responding to the modification operation of the first user in the character area to be modified, and executing the modification of the candidate first session information into first session information; and sending the first session information to network equipment corresponding to the social application, wherein the network equipment is used for sending the first session information to second user equipment. For example, a first user inputs subsequent first session information in an input box in the session interface, the first user clicks a send button of a second user in the session interface to generate a first trigger event, in response to the first trigger event, the first user device detects in advance whether a candidate first session information to be sent by the first user exists in a text area to be modified, if so, the first user device marks (e.g., highlights) a text in the text area to be modified in the first session information, marks the text as a prompt that the first user needs to modify the text (e.g., whether the text needs to be modified), and presents a modified text style recommended by the first user device, the first user can directly agree with the modified text style recommended by the first user device to directly replace the text in the text area to be modified with the modified text style, or the first user directly modifies the text in the text area to be modified according to his own understanding, the modified content (for example, the first session information) is generated, then, the first user equipment sends the first session information to the network equipment so that the network equipment can send the first session information to the second user equipment, and on the premise that the session information input by the first user is modified in advance, the workload required for operation is smaller when the subsequent network equipment modifies the first session information after re-detecting the first session information, so that the processing efficiency of the network equipment is improved.

Fig. 6 is a schematic diagram illustrating sending of session information in a social application according to an embodiment of the present application, where a user opens a chat interface, the user edits text content in the chat interface, an intelligent system (e.g., a current user device) determines in real time whether the text content is wrong, if no error occurs, the user continues editing the text content, if an error occurs, the intelligent system marks and promotes an error area, the user determines whether to modify the text content, if so, the user modifies the text content according to an intelligent prompt and sends the modified text content after editing, otherwise, the user continues editing the content. If the intelligent system judges that the text content has errors in real time, the intelligent system modifies the error area and prompts the user after modification, the user judges whether the text content needs to be modified, if so, the user continues to edit the rest content and sends the content after editing, otherwise, the intelligent system changes the text content into the previous content. After the text content is sent to an intelligent system (here, a server), the server judges whether errors occur in the text content, and if the errors do not occur, the text content is sent to a friend; otherwise, the server modifies the error area, the modified content is sent to the user and prompts whether to determine the modified content, if so, the server sends the modified text content to the user, otherwise, the text content is sent to the friend without being modified.

After the information is sent to the friend client side, under the condition that the friend checks the information, if the user finds that the sent text information is wrong, the user or an intelligent system (server) judges whether the wrong place needs to be modified, if so, the wrong area is directly modified, the modified content is sent to the friend, and the friend client side directly presents the modified content and a modification prompt; if only the intelligent device finds that the sent text information is wrong, the error area is directly modified, the modified content is sent to the friend, and the friend client side directly presents the modified content and the message updating notice and sends an error prompt to the user.

After the information is sent to the friend client, under the condition that the friend does not check the information, if the user finds that the sent text information has errors, the user judges whether the error place needs to be modified or not, if so, the user or an intelligent system (server) directly modifies the error area and sends the modified content to the friend, the friend client directly presents the modified content, and if the friend checks the previous information in the modification process, the server prompts the friend to modify the content of the message; if the user finds that the sent character information is wrong, the user judges whether the wrong place needs to be modified, if so, the user or an intelligent system (server) directly modifies the wrong area and sends the modified content to the friend, the friend client side directly presents the modified content, and if the friend checks the previous information in the modification process, the server cancels the modification and improves that the user cannot modify.

After the information is sent to the friend client, under the condition that the friend does not check the information, the intelligent system checks that the character has an error, directly modifies the error area, prompts the user to modify the message content after modification, and prompts the server to modify the message content of the friend if the friend checks the previous information in the modification process; or if the friend checks the previous information in the modification process, the server prompts the friend to modify the content of the information, cancels the modification and improves that the user cannot modify the content.

Fig. 7 shows a network device for sending session information in a social application according to an embodiment of the present application, where the network device includes a one-module 101, a two-module 102, and a three-module 103.

Specifically, the one-to-one module 101 is configured to receive first session information sent by a first user equipment in response to a trigger event in a session interface of a social application, and send the first session information to a second user equipment. For example, a social application is installed in a first user device, the first user device presents a session interface of the social application, a first user inputs first session information in an input box in the session interface, where the first session information includes character information (e.g., text information, symbol information), expression information, and the like, the session interface is the session interface of the first user and a second user, the first user clicks a send button of the second user in the session interface to generate a trigger event, the first user device sends the first session information to a network device, and the network device sends the first session information to the second user device. In some embodiments, the session interface includes a chat interface between the first user and another user (e.g., one or more) and the second user device is any one of the other users (user a, user B, user C …), and it is not limited to that the first session information is viewed by any one user in the session interface as long as the first session information is viewed by any one user in the session interface when the subsequent network device detects the reading state of the first session information.

A second module 102, configured to detect whether the first session information has an area to be modified after the first session information is successfully sent, and if so, detect a reading state of the first session information, and if the reading state includes that the first session information is not checked by a second user, modify the first session information into second session information. For example, the second user device has received the first session information, and after that, the network device actively recognizes whether there is an error in the first session information, for example, there is a word error in the first session information (e.g., the first user originally sends "your son is old this year", but last sends "your word is old this year", for example, the first user originally sends "i is sick, coughed for several days", but finally sends "i is sick, coughed for several days" to the second user), or there is a semantic error, which causes the whole text table to be unclear (e.g., the first user originally sends "i wants to detect whether this application really has a teaching function", but last sends "i wants to detect whether this application really has a correction function"), a harmony word (e.g., a pair of eyes-glasses), a pair of eyes-glasses, a pair of eyes-glasses, confusing sound words (e.g., wandering girl-cowshed girl), word order reversal (e.g., wood-allen-alenwood), word completion (e.g., love-if love is happy), grammatical errors (e.g., imagine difficult-imagine), etc., the network device may employ some text error correction algorithms (e.g., wrongly written word dictionary, edit distance, language model (ngram LM, DNN LM, word-based model), etc.) to identify whether there are regions in the first session information that need to be modified, e.g., the first session information is not all-segment-word error, possibly partial error (e.g., beginning, middle segment, or end of the entire segment). If the first session information has an error, the network device acquires the reading state of the first session information in real time, and if the current reading state includes that the first session information is not viewed by the second user, the network device determines that the first session information can be modified under the condition that the second user does not sense, and modifies the first session information into the second session information based on a text error correction algorithm (for example, the first session information can be participled first and then fuzzy matching is adopted).

A third module 103, configured to send the second session information to the second user equipment, where the second session information is used to replace a location of the first session information in the second user equipment, or the second session information is used to be superimposed on a location of the first session information in the second user equipment. On the basis of the modification of the second session information, the network device can send the second session information to the second user device under the condition that the second user does not perceive the second session information so as to replace the first session information to be presented in a session interface of the second user device. For example, after receiving the second session information, the second user equipment hides the first session information and superimposes the second session information on the first session information, or the second user equipment cancels the first session information and replaces the second session information for presentation. In some embodiments, in order to make the information that is seen by the first user and the second user finally opening the social application consistent and not misunderstood, after the second session information is successfully replaced by the first session information at the second user equipment, the network device sends the second session information to the first user equipment to replace the first session information presented in the first user equipment by the second session information, and may notify the first user of the replacement of the information to improve user experience.

Fig. 8 shows a network device for sending session information in a social application according to an embodiment of the present application, where the network device includes a two-to-one module 201, a two-to-two module 202, a two-to-three module 203, and a two-to-four module 204.

Specifically, the first module 201 is configured to receive first session information sent by a first user equipment in response to a first trigger event in a session interface of a social application, and send the first session information to a second user equipment. For example, a social application is installed in a first user device, the first user device presents a session interface of the social application, a first user inputs first session information in an input box in the session interface, where the first session information includes character information (e.g., text information, symbol information), expression information, and the like, the session interface is the session interface of the first user and a second user, the first user clicks a send button of the second user in the session interface to generate a first trigger event, the first user device sends the first session information to a network device, and the network device sends the first session information to the second user device. In some embodiments, the session interface includes a chat interface between the first user and another user (e.g., one or more) and the second user device is any one of the other users (user a, user B, user C …), and it is not limited to that the first session information is viewed by any one user in the session interface as long as the first session information is viewed by any one user in the session interface when the subsequent network device detects the reading state of the first session information.

A second module 202, configured to receive a first modification request sent by the first user equipment in response to a second trigger event in the social application, detect, in response to the first modification request, a reading status of the first session information, and return modification instruction information to the first user equipment if the reading status includes that the first session information is not viewed by a second user, where the modification instruction information includes permission for modification, and the first modification request includes identification information of the first session information. For example, a button is present in the session interface of the first user equipment, the button has a function for requesting the first user to modify the sent session information, in response to the triggering operation of the button by the first user, the first user equipment generates a second triggering event, and sends a first modification request to the network equipment based on the second triggering event, wherein the first modification request is used for requesting to acquire the right to modify the first session information, the network device responds to the first modification request, detects whether the first session information is viewed by the second user, if the first session information is not viewed, the network device determines that the first session information can be replaced subsequently without the perception of the second user, and sending the content which the first user wants to modify to the second user equipment, wherein the network equipment agrees that the first user obtains the modification authority about the first session information and returns modification instruction information allowing modification to the first user equipment. For another example, in response to a triggering operation (e.g., a revocation operation) by the first user on the first session information in the session interface, the first user device generates a second triggering event and sends a first modification request to the network device based on the event, the network device returns an instruction to allow modification to the first user if the first session information is not viewed by the second user based on the first modification request, and performs a revocation operation (e.g., hides the first session information) on the first session information in the second user device to send content that the first user wants to modify to the second user device subsequently without the second user's perception.

A second-third module 203, configured to receive a second modification request sent by the first user equipment in response to the modification instruction information, where the second modification request includes second session information, and the second session information is generated after the first user edits the first session information. For example, after the first user equipment receives the modification instruction information allowing modification, the first user equipment directly presents the first session information in a chat input box of a session interface of the first user equipment, the first user does not need to re-input the whole segment, the first user equipment directly modifies the first session information on the basis of the first session information, and after the first user finishes modifying the first session information, the first user equipment sends a second modification request to the network equipment in response to a re-triggering operation of the first user (for example, clicking a button after the modification is finished to send the modified first session information, that is, the second session information), and the second modification request is used for replacing the sent first session information with the second session information.

A fourth module 204, configured to send the second session information to the second user equipment in response to the second modification request, and return modification feedback information to the first user equipment, where the second session information is used to replace a location of the first session information in the second user equipment, or the second session information is used to be superimposed on a location of the first session information in the second user equipment. For example, the network device sends the second session information to the second user device under the condition that the second user is unaware (that is, under the condition that the page where the first session information is located is not viewed), so that the second user device hides the first session information after receiving the second session information, and superimposes the second session information on the first session information, or the second user device withdraws the first session information, and replaces the second session information to present the second session information. In some embodiments, in order to make the information seen by the first user and the second user finally opening the social application consistent and not misunderstood, the first session information displayed in the first user equipment is replaced with the second session information when the first user equipment sends the second modification request. And after the network equipment successfully sends the second session information, returning the successfully modified information to the first user equipment.

Here, examples of specific implementation manners of the two-in-one module 201, the two-in-two module 202, the two-in-three module 203, and the two-in-four module 204 are the same as or similar to those of the embodiment related to steps S201, S202, S203, and S204 in fig. 4, and therefore are not repeated herein and are included herein by reference.
