In accordance with an embodiment of the present invention, there is provided a message display method, it being noted that the steps illustrated in the flow chart diagrams of the figures may be carried out in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow chart diagrams, in some cases, the steps illustrated or described may be carried out in an order different than here.

Fig. 2 is a flowchart of a message display method according to an embodiment of the present invention, as shown in fig. 2, the method is applied to a terminal device, an instant messaging interface is provided through the terminal device, and a sent first message is displayed in the instant messaging interface, and the method includes the following steps:

step S201, in response to the withdrawal operation performed on the first message, hiding the first message in the instant messaging interface, and acquiring a reading state of the first message.

Specifically, the terminal device may be a smart phone (including an Android phone and an IOS phone), a tablet computer, a notebook computer, a personal computer, or the like, used by a user for receiving a message, and the device may be installed with instant messaging software, so that an instant messaging interface may be displayed on a display screen of the device. The first message may be a message that the user sends to other users within a certain time, and the message may include but is not limited to: text or pictures. The reading state of the first message is used for indicating whether the first message is read by a user receiving the message before being withdrawn, and can be divided into a read state and an unread state.

In an alternative embodiment, the user a sends the first message to the user B, the first message may be displayed in the instant messaging interface of the user B, and then the user a selects to withdraw the first message, and the instant messaging interface of the user B may hide the first message, so as to withdraw the first message. After the user a sends the first message, the reading state of the first message is an unread state, and after the instant messaging interface is displayed on the terminal device of the user B, the terminal device can record that the reading state of the first message is a read state, so that the terminal device can acquire the reading state of the first message. It should be noted that after the user a performs the revocation operation on the first message, the reading status of the first message is not changed.

Step S202, in response to the editing operation performed on the first message, a second message is obtained, where the second message is obtained by editing the first message.

Specifically, after the user withdraws the first message, the user may edit the first message again to obtain the second message. In an optional embodiment, a control for editing the first message may be provided in the instant messaging interface, for example, after the user a withdraws the first message, a re-editing control may be displayed in the instant messaging interface of the user a, and the user a may modify and edit the first message by performing a touch operation on the control. After the user a performs touch operation on the re-editing control, it is determined to perform editing operation on the first message, at this time, a message input box may be displayed in the instant messaging interface of the user a, and the first message that has been withdrawn is displayed in the input box, and the user a may perform editing on the basis of the first message, so as to obtain a second message.

Step S203, comparing the first message with the second message to obtain a comparison result, where the comparison result is used to represent whether the first message is the same as the second message.

It should be noted that, in the instant messaging scenario, the message sent by the user a to the other user is often a text message or a picture (without any text), and therefore, the types of the first message and the second message may be a text message or a picture message.

In an alternative embodiment, in the case that the first message and the second message are text messages, the words in the first message may be used as a reference template, each word in the second message is sequentially compared, and the repetition degree between the two is determined, and in the case that the repetition degree is greater than or equal to a first threshold (which may be set by a manager, for example, may be 100%), it indicates that the first message and the second message are the same, so that the comparison result of the unmodified first message may be obtained; and in the case that the repetition degree is less than the first threshold value, the first message and the second message are not the same, so that the comparison result of the modified first message can be obtained.

In another optional embodiment, in the case that the first message and the second message are picture messages, it may be determined whether the first message and the second message are identical by performing similarity calculation on the first message and the second message; alternatively, it may be determined whether the first message and the second message are the same by comparing the degree of overlap of the outlines of the picture in the first message and the picture in the second message. Specifically, the contour overlapping degree of the picture in the first message and the picture in the second message may be calculated as follows: the method comprises the steps of firstly processing a first message and a second message to enable the pictures to be changed into black and white pictures or gray pictures, then extracting pixel points with color values above a second threshold value (which can be set by a manager, for example, 70%) from the two processed pictures, placing the two processed pictures on the same coordinate, recording the extracted pixel points, and finally calculating the coordinate coincidence degree of the recorded pixel points. In the case that the coincidence degree is greater than or equal to the third threshold value (which may be set by the administrator at its discretion, for example, may be 90%), it indicates that the first message and the second message are the same, and therefore, the comparison result of the unmodified first message may be obtained; in the case that the coincidence degree is smaller than the third threshold value, it indicates that the first message is different from the second message, and therefore the comparison result of the modified first message can be obtained.

And S204, generating a modification trace based on the first message and the second message in response to the reading state being the read state and the comparison result being that the first message is different from the second message.

Specifically, the modification trace may be a process in which the user a modifies the first message to obtain the second message, for example, taking the first message as a text message as an example, the modification trace may be a process in which the user a deletes part or all of the characters in the first message and adds other characters to obtain the second message. It should be noted that the modification trace may not only include the difference between the first message and the second message, but also include the same content between the two messages.

In an alternative embodiment, after the user B who receives the message has read the first message, that is, the terminal device of the user B records the reading status of the first message as the read status, if it is determined that the first message is different from the second message, in order to avoid the user B reading repeatedly, modification traces may be generated based on the first message and the second message in different ways for different types of messages.

In the case where the first message and the second message are text messages, if it is determined that the first message and the second message are different, a modification trace may be generated based on the difference of the first message and the second message and the same content; in the case where the first message and the second message are picture messages, if it is determined that the first message and the second message are different, the first message and the second message may be directly used as a modification trace.

And S205, displaying the modification trace in the instant messaging interface.

In an alternative embodiment, modification traces may be displayed in the instant messaging interface of the user B, and in order to facilitate the user B to quickly and accurately determine the modification process of the user a, in the case that the first message and the second message are text messages, the modification traces may be displayed as follows: modifying the display mode corresponding to each character in the trace, wherein the display modes of the first character, the second character and the repeated character are different; and displaying the modification trace in the instant messaging interface according to a display mode. Specifically, the first message may be used as a reference template, the newly added part may be displayed according to a first preset display mode, the deleted part may be displayed according to a second preset display mode, and the unchanged part may be displayed according to a third preset display mode. The third preset display mode may be a message default display mode, for example, a default font color, or the like; the first preset display mode and the second preset display mode may be set according to actual requirements, for example, the first preset display mode may display characters as green, and the second preset display mode may display red deletion lines on the deleted characters. In the case that the first message and the second message are picture messages, a thumbnail of the first message can be displayed in the instant messaging interface, a file of 'the picture is withdrawn' is marked, and the second message is displayed at the same time.

It should be noted that, in the instant messaging software, in order to improve the reading experience of the user, two display modes can be provided for the user, which are a reader mode and an unread mode respectively, and in the case that the display mode is the reader mode, a modification trace can be displayed in the instant messaging interface; in case the display message is in unread mode, the second message may be directly displayed. Specifically, the user can switch the display mode of the second message by clicking the mode switching control displayed in the instant messaging interface according to the needs of the user.

Optionally, in response to the comparison result being that the first message is the same as the second message, that is, if the user a does not modify the first message, the second message may be directly displayed in the instant messaging interface of the user B, so that the user B may determine that the user a does not modify the first message. In response to that the reading state is an unread state, and the comparison result is that the first message is different from the second message, that is, if the user B does not read the first message before the first message is withdrawn, there is no problem of repeated reading.

Optionally, in response to the first message and the second message being text messages, generating the modification trace based on the first message and the second message comprises: sequentially comparing each character contained in the first message with each character contained in the second message to determine repeated characters in the first message and the second message; determining first characters except for the repeated characters in the first message; determining second characters except for the repeated characters in the second message; and generating a modification trace based on the first character, the second character and the repeated character.

Specifically, the first text is text existing in the first message but not existing in the second message, that is, text deleted during the editing operation performed by the user a on the first message. The second text may be text that is not present in the first message but is present in the second message, that is, text added in the process of editing the first message by the user a.

In an alternative embodiment, the first message and the second message may be compared word by word, the text present in both the first message and the second message is determined, the repeated text is obtained, the text present only in the first message is further determined, the first text is obtained, and the text present only in the second message is obtained the second text is obtained. Then, different display modes can be set for the first characters, the second characters and the repeated characters, so that a user can clearly know the difference between the first message and the second message when viewing the second message. As shown in fig. 3, fig. 3 may be the communication interface of user B, the first message may be "want to you eat" sent by user a, the second message may be "want to you eat barbecue in tomorrow and then watch movie" sent by user a, the first message and the second message are compared to determine that the repeated text may be "want to you" and "eat", the first text may be "meal", and the second text may be "tomorrow" and "barbecue and then watch movie".

Specifically, after the first text, the second text, and the repeated text are determined, the arrangement order among the first text, the second text, and the repeated text may be determined according to a first arrangement order between the first text and the repeated text in the first message and a second arrangement order between the second text and the repeated text in the second message, and then the first text, the second text, and the repeated text may be sorted according to the arrangement order to obtain the modification trace. As shown in fig. 3, the first arrangement order may be "want you to" + "eat" + "meal", and the second arrangement order may be "want you to" + "tomorrow" + "eat" + "grill, then watch a movie".

Specifically, in the actual display process, the first text, the second text and the repeated text are displayed in different manners, and are used for prompting the user of a place where the first message is different from the second message. In the actual application process, the first characters, the second characters and the repeated characters can be displayed in any different formats. For example, the first, second and repeated text may be displayed in different text colors, e.g., the repeated text is displayed in black, the first text is displayed in red and the second text is displayed in green. Alternatively, the first character is marked out with a strikethrough, the repeated characters remain in the original format, and the second character is underlined.

In practical applications, the format of the first character is not limited to the above-mentioned labeling method, and other methods may be used for labeling, for example, parentheses, red highlighting, etc., the second character is not limited to the above-mentioned labeling method, and other formats such as bold, italic, green highlighting, etc., may be used for labeling, and the present application is not limited to the display method of the above-mentioned first character, second character, and repeated characters.

Specifically, the display order between the first text and the second text may be determined by a user operation, for example, the user a adds or deletes text in the first message, and the arrangement order is determined according to the position of the cursor when the user edits the second message. Optionally, in response to the first message and the second message being picture messages, generating a modification trace based on the first message and the second message includes: carrying out thumbnail processing on the first message to obtain a thumbnail picture; marking the thumbnail to generate a marked picture; and displaying the marked picture and the second message in the instant messaging interface.

Specifically, the above marking of the thumbnail picture may be displaying a "the picture has been withdrawn" file next to the thumbnail picture, and displaying the mark in the instant messaging interface of the user B, so that the user B can see the thumbnail picture of the first message and the second message at the same time, and thus can quickly know the difference between the first message and the second message. For example, as shown in fig. 4A, a diagram B may be a first message, a diagram a may be a second message, and in case that the user a signals an image transmission error, the user a may withdraw the diagram B and retransmit the diagram a, and display a thumbnail of the diagram B and a thumbnail mark on the upper side of the diagram a.

It should be noted that the display positions of the thumbnails and the thumbnail marks are not limited to the upper side of fig. a, and may be located at the lower side or both sides, and the present application is not limited thereto.

Optionally, comparing the first message with the second message to obtain a comparison result includes: acquiring the outline overlapping degree of the first message and the second message; and comparing the contour overlapping degree with a preset threshold value to obtain a comparison result.
