Description

Information recommendation method, device and electronic device

Technical Field

The present invention relates to the technical field of input methods, and in particular to an information recommendation method, device and electronic equipment.

Background Art

With the development of computer technology, electronic devices such as mobile phones and tablet computers are becoming more and more popular, bringing great convenience to people's life, study and work. These electronic devices are usually installed with input method applications (input methods for short), so that users can use the input methods to input information.

Among them, the input method not only provides text input, but also provides emoticon input, that is, after the user enters an emoticon keyword, the input method can output the corresponding emoticon for the user to choose. Among them, only when the information entered by the user is a single emoticon keyword, the input method can match the corresponding emoticon picture, and if the information entered by the user includes other text information in addition to a single emoticon keyword, such as the input information contains multiple emoticon keywords, the input method cannot match the corresponding emoticon picture. For example, "OK" and "Hmm" are both emoticon keywords. After the user enters "Hmm", the corresponding emoticon picture can be recommended, but if the user enters "Hmm OK", no emoticon picture can be recommended; as a result, the user needs to delete part of the content to obtain the required emoticon picture, or search for it separately, affecting the input efficiency.

DETAILED DESCRIPTION

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

One of the core concepts of the embodiment of the present invention is to extract keywords from the input content, match and display corresponding emoticon images for each keyword, and then recommend corresponding emoticon images for each keyword in the input content, thereby improving input efficiency.

1 , a flowchart of an information recommendation method embodiment of the present invention is shown, which may specifically include the following steps:

Step 102: Obtain input content and extract at least one keyword corresponding to the input content.

The embodiment of the present invention can obtain the input content, extract keywords from the input content, and then match the corresponding emoticon images for the keywords and recommend them, so as to recommend the corresponding emoticon images for each keyword in the input content. Wherein, the input content can refer to the information input into the corresponding edit box of the application, such as the candidate selected by the upper screen instruction, and the information input by the user using the editing operation such as the paste operation, and the present invention does not limit this; wherein, the name of the edit box in different applications may be different, for example, the edit box in the chat application is an information input box, and the information edit box in the browser is a search box, etc. The input content can also refer to the candidate information determined according to the input sequence, such as the candidate determined according to the input sequence. Wherein, the input content can be analyzed and processed such as word segmentation processing, and at least one corresponding keyword can be extracted from the input content; for example, after analyzing and processing the input content of "hmm, ok", two keywords "hmm" and "ok" can be extracted, and for example, after analyzing and processing the input content of "good morning, what are you going to eat this morning?", five keywords "good morning", "today", "morning", "prepare" and "what to eat" can be extracted.

Step 104: search for emoticon images corresponding to the keywords, wherein each keyword corresponds to at least one emoticon image.

Step 106: display the expression picture.

In an embodiment of the present invention, after extracting keywords from the input content, corresponding matching emoticon images can be searched for each keyword based on the keyword; wherein, the emoticon images corresponding to each keyword can be searched from an emoticon image library, and the emoticon image library can be stored locally or in a server; or the emoticon images corresponding to each keyword can be searched from the network, and the embodiment of the present invention does not limit this. In an embodiment of the present invention, the keywords corresponding to multiple emoticon images may be the same, or the keywords corresponding to one emoticon image may be different from the keywords corresponding to other emoticon images; therefore, the emoticon images found for each keyword may be one or more. In an embodiment of the present invention, there may be corresponding emoticon images for some keywords, and there may be no corresponding emoticon images for some keywords, so the found emoticon images can be displayed; wherein, the display area of the emoticon images can be set according to needs, such as the candidate area, association area, etc. of the input method, and of course it can also be the set display area of the application, and the embodiment of the present invention does not limit this.

In an example of the present invention, the input content obtained is "Um, ok", and the two keywords "uh-huh" and "ok" of the input content can be used to search for the emoticon image corresponding to the keyword "uh-huh" and the emoticon image corresponding to the keyword "ok" respectively; among them, the emoticon images of these two keywords can be found, and then the emoticon images of these two keywords can be displayed, as shown in Figure 2.

In another example of the present invention, the input content obtained is "The first picture is good-looking", and three keywords "first", "picture" and "good-looking" can be extracted from the input content, and then the expression picture corresponding to the keyword "first" is searched for, the expression picture corresponding to the keyword "picture" is searched for, and the expression picture corresponding to the keyword "good-looking" is searched for; among them, the expression picture corresponding to the keyword "good-looking" can be found, and the corresponding expression pictures cannot be found for the other two keywords, and then the expression picture of the keyword "good-looking" can be displayed, as shown in Figure 3.

In an embodiment of the present invention, after obtaining the input content, at least one keyword corresponding to the input content can be extracted, and then the emoticon image corresponding to the keyword can be searched and displayed; thereby, the corresponding emoticon image can be recommended for each keyword in the input content, thereby improving input efficiency.

In another embodiment of the present invention, mapping information can be pre-established, and the mapping information can be used to characterize the mapping relationship between emoticon images and corresponding keywords. When searching for emoticon images corresponding to keywords, the mapping information can be searched based on the keywords to determine the emoticon images corresponding to the keywords.

4a, a flowchart of an optional embodiment of an information recommendation method of the present invention is shown, which may specifically include the following steps:

Step 402: Obtain input content.

In an embodiment of the present invention, information in an edit box of an application can be obtained, and the information can be determined as input content, wherein the information in the edit box can be input by a user in the edit box of the application through an editing operation, such as using a paste operation to input pre-copied information; or it can be input in the edit box of the application using an input method, for example, after the user enters an input sequence, the input method can convert the input sequence to obtain corresponding candidate items and display them in the candidate area, and then the user can perform an on-screen operation to select a candidate item that meets the requirements; after the user performs the on-screen operation, the input method can generate an on-screen instruction corresponding to the on-screen operation, and then the candidate item corresponding to the on-screen instruction is on-screen to the edit box of the application. Of course, when the user uses the input method to input, the candidate information obtained by the input method based on the input sequence input by the user can also be obtained, and the obtained candidate information can be determined as input content. Then, at least one corresponding keyword is extracted from the input content, and corresponding emoticon pictures are recommended for each keyword.

Step 404: perform word segmentation processing on the input content to obtain word segmentation fragments.

Step 406: Determine at least one keyword corresponding to the input content based on the word segmentation fragments.

In the process of extracting keywords corresponding to the input content, the embodiment of the present invention may perform word segmentation processing on the input content to obtain corresponding word segmentation fragments; then determine at least one keyword corresponding to the input content based on the word segmentation fragments. For example, the input content "this movie is so scary" is subjected to word segmentation processing to obtain word segmentation fragments: "this", "movie", "good" and "scary", and three keywords "this", "movie" and "scary" can be obtained; for another example, the input content "autumn outing tomorrow" is subjected to word segmentation processing to obtain word segmentation fragments "tomorrow" and "autumn outing", and the corresponding keywords can be the same as the word segmentation fragments, that is, the keywords can also be "tomorrow" and "autumn outing".

Step 408: Search mapping information based on the keyword to determine at least one emoticon image corresponding to the keyword.

In the embodiment of the present invention, after extracting multiple keywords from the input content, predetermined mapping information may be searched for each keyword according to the keyword, and then the emoticon image corresponding to the keyword may be determined according to the found mapping information.

In an optional embodiment of the present invention, the keywords corresponding to each emoticon image can be predetermined, wherein, in order to distinguish the keywords corresponding to the emoticon image from the keywords corresponding to the input content, the keywords corresponding to the emoticon image can be referred to as emoticon keywords. Then, a mapping relationship between each emoticon image and the corresponding emoticon keyword is established, such as a mapping relationship between the emoticon keyword and the image information of the emoticon image, and then mapping information is determined based on the mapping relationship, for example, the mapping relationship is used as mapping information; and then the mapping information may include the mapping relationship between the emoticon image and the corresponding emoticon keyword, so determining at least one emoticon image corresponding to the keyword can be implemented by the following sub-steps 81-82:

Sub-step 81 : matching the keyword with an expression keyword to determine an expression keyword that matches the keyword.

Sub-step 82: searching for at least one expression picture corresponding to the matched expression keyword according to the mapping relationship.

In an embodiment of the present invention, the keyword can be matched with all the expression keywords in the mapping relationship to find the expression keyword that matches the keyword; then the mapping relationship corresponding to the matched expression keyword is determined, and then the picture information corresponding to the matched expression keyword is determined based on the mapping relationship; and then the corresponding expression picture is found based on the picture information.

Step 410: Obtain associated information, where the associated information includes context information and/or user behavior data.

Step 412: filter the expression pictures according to the associated information.

In the embodiment of the present invention, the type of emoticon images selected by users in different scenarios may be different. For example, if the user is a young person, when chatting with elders in a chat application, he is likely to choose emoticon images that are more suitable for middle-aged people, while when chatting with peers, he is likely to choose emoticon images that are more suitable for young people. And different users like to use different styles of emoticons. For example, some users like their emoticon images to be emoticon images of movie characters, some users like emoticon images of cartoon characters, some users like currently popular emoticon images, some users like animal emoticon images, and so on. Therefore, in the embodiment of the present invention, context information, user behavior data and other related information can be obtained, and then the emoticon images can be screened based on the related information to make the recommended emoticon images more in line with the needs of users.

Step 414: display the emoticon image in the display area of the input method.

In an embodiment of the present invention, after the emoticon images are screened, the screened emoticon images can be displayed in the display area of the input method, wherein the display area includes at least one of the following: a candidate area, an association area, and a keyboard area; of course, the emoticon images can also be displayed in the setting area of the application. When the keyword includes multiple keywords, the emoticon images corresponding to each keyword can be displayed, wherein the method of displaying the emoticon images corresponding to each keyword can also be set according to the requirements.

In an example of the present invention, for a situation where a keyword corresponds to multiple emoticon images, the multiple emoticon images corresponding to each keyword can be displayed in multiple columns in the display area, and the user can view the multiple emoticon images corresponding to each keyword by sliding left and right. In an example of the present invention, the content "Uh-huh, ok, no problem" has been input, and three keywords "uh-huh", "ok", and "no problem" have been extracted, among which the keyword "uh-huh" corresponds to one emoticon image, the keyword "ok" corresponds to four emoticon images, and the keyword "no problem" corresponds to two emoticon images; as shown in Figure 4b, the display area in Figure 4b does not show an emoticon image corresponding to the keyword "ok" and an emoticon image corresponding to the keyword "no problem". After the user slides to the left, the emoticon image corresponding to the keyword "ok" that is not displayed in Figure 4b can be viewed, and reference can be made to Figure 4c.

In another example of the present invention, when a keyword corresponds to multiple emoticons, multiple emoticons corresponding to each keyword can also be scrolled and displayed in a column in the display area; based on the previous example, refer to Figure 4d (the scrolling display effect is not shown in the figure). Among them, the user can view by triggering the viewing instruction, such as by sliding up in the column to view, for example, in Figure 4d, the user slides in the column corresponding to the keyword "好哒" to view another emoticon keyword corresponding to the keyword "好哒", and refer to Figure 4e.

In another example of the present invention, when a user stays on an emoticon image of a certain keyword, the emoticon images corresponding to other keywords presented in the display area may be related series images of the series to which the emoticon image belongs. Among them, two series with an association relationship (such as the same or related themes and objects, the same author, etc.) can be called related series. For example, any two series of Little Yellow Duck Series-1, Little Yellow Duck Series-2 and Little Yellow Duck Series-3 can be called related series; for example, any two series of Fu Xiao Miao Daily Series, Fu Xiao Miao Spring Festival Series and Fu Xiao Miao Red Envelope Series can also be called related series; for example, the user stays on the emoticon image corresponding to the keyword "OK" as shown in Figure 4e, and the emoticon image corresponding to the keyword "No problem" in the display area can be as shown in Figure 4f. In an embodiment of the present invention, the related series may include the same series.

In an embodiment of the present invention, after obtaining the input content, at least one keyword corresponding to the input content can be extracted, and then the emoticon image corresponding to the keyword can be searched and displayed; thereby, the corresponding emoticon image can be recommended for each keyword in the input content, thereby improving input efficiency.

Secondly, in an embodiment of the present invention, after determining the emoticon image corresponding to the keyword, the emoticon image can also be filtered, wherein related information can be obtained, and the emoticon image can be filtered based on the related information, wherein the related information includes context information and/or user behavior data; thereby satisfying the user's personalized needs and improving the user experience.

In another embodiment of the present invention, when there are more than one keywords, the display area can display emoticon images corresponding to multiple keywords; then the user can select one or more emoticon images corresponding to the keywords to display on the screen or send them by performing the display operation in the display area.

5, a flowchart of an embodiment of a method for putting an expression picture on the screen of the present invention is shown, which may specifically include the following steps:

Step 502: Obtain a screen display instruction based on the display area, and display the expression picture corresponding to the screen display instruction on the screen.

In an embodiment of the present invention, a user can perform a screen-up operation in the display area, and select an emoticon image that meets the needs from the display area; and then after the user performs the screen-up operation in the display area, the input method can determine the screen-up instruction based on the display area according to the screen-up operation, and then put the emoticon image corresponding to the screen-up instruction on the screen. Wherein, if multiple emoticon images of keywords are determined, the display area can display multiple emoticon images of keywords, and then the user can select an emoticon image of a keyword each time the screen-up operation is performed; wherein, the input method can put the emoticon image corresponding to the screen-up instruction on the screen each time the screen-up operation corresponding to the screen-up operation is received, that is, the user can select an emoticon image of a keyword to be put on the screen each time. Of course, the input method can also put the emoticon images corresponding to multiple screen-up instructions on the screen at the same time after receiving multiple screen-up operations corresponding to the screen-up instructions, that is, the user can select multiple emoticon images of keywords to be put on the screen each time.

Step 504: Determine that the emoticon image on the upper screen corresponds to a keyword, delete the emoticon image corresponding to the keyword from the display area, and update the display area.

In the embodiment of the present invention, when there are more than one keyword, after putting at least one emoticon picture of the keyword on the screen according to the on-screen instruction, the emoticon pictures corresponding to these keywords can be deleted from the display area to update the display area. Therefore, it can be determined that the emoticon picture on the screen corresponds to the keyword, and the emoticon picture corresponding to the keyword is deleted from the display area; wherein, when there is one emoticon picture corresponding to the keyword, the emoticon picture corresponding to the keyword is the emoticon picture on the screen, and the emoticon picture on the screen is deleted from the display area; when there are more than one emoticon picture corresponding to the keyword, the multiple emoticon pictures corresponding to the keyword are deleted from the display area.

In an optional embodiment of the present invention, the emoticons corresponding to other keywords in the updated display area include related series of pictures of the series to which the emoticon picture on the upper screen belongs. This is similar to the above-mentioned emoticon pictures corresponding to other keywords presented in the display area when the user stays on an emoticon picture of a certain keyword, which can be related series of pictures of the series to which the emoticon picture belongs, and will not be repeated here.

Step 506: Obtain a screen display instruction based on the updated display area, and display the expression picture corresponding to the screen display instruction on the screen.

When there are still emoticon images required by the user in the updated display area, the user can perform the on-screen operation again in the updated display area; then the input method can determine the on-screen instruction based on the updated display area according to the on-screen operation, and then put the emoticon image corresponding to the on-screen instruction on the screen, and then update the display area again according to the method described in step 504.

In an example of the present invention, the content "hmm, ok, OK" has been input, and three keywords "hmm", "ok", and "ok" have been extracted, wherein the keyword "hmm" corresponds to two emoticon images, and the other two keywords each correspond to one emoticon image; then the display area displays the emoticon images of the three keywords, namely, emoticon 1, emoticon 2, emoticon 3, and emoticon 4, wherein emoticon 1 and emoticon 2 are emoticon images corresponding to the keyword "hmm", emoticon 3 is the emoticon image corresponding to the keyword "ok", and emoticon 4 is the emoticon image corresponding to the keyword "ok", as shown in Figure 6a. Among them, the input method can put the emoticon image corresponding to the screen-up instruction on the screen every time it receives a screen-up instruction, and then the user can put one emoticon image on the screen each time; for example, the user can select the emoticon image corresponding to "hmm", wherein after the user performs the screen-up operation for emoticon 1 in Figure 6a, the input method obtains the corresponding screen-up instruction, determines that the emoticon image corresponding to the screen-up instruction is emoticon 1, and puts emoticon 1 on the screen to the edit box. Then it is determined that the keyword corresponding to emoticon 1 is "hmm", and the emoticon images corresponding to "hmm" can be deleted in the display area: emoticon 1 and emoticon 2, and the display area is updated, as shown in Figure 6b. The user can also select the emoticon image corresponding to the keyword "OK", wherein the user performs the on-screen operation for emoticon 3 in FIG6b, and the input method obtains the corresponding on-screen instruction, determines that the emoticon image corresponding to the on-screen instruction is emoticon 3, and puts emoticon 3 on the screen to the edit box. Then, it is determined that the keyword corresponding to emoticon 3 is "OK", and the emoticon image corresponding to "OK" can be deleted in the display area: emoticon 3, and the display area is updated, as shown in FIG6c. The user can also select the emoticon image corresponding to the keyword "OK", which will not be repeated here.

In another example of the present invention, the input method can also simultaneously put the emoticons corresponding to the multiple on-screen instructions on the screen after receiving the on-screen instructions corresponding to the multiple on-screen operations; as shown in FIG6a, when the user selects the emoticon corresponding to the keyword "hmm", the on-screen operation is performed for emoticon 1, and then when the user selects the emoticon corresponding to the keyword "ok", the on-screen operation is performed for emoticon 3; the input method determines that the emoticons corresponding to the on-screen instructions of the two on-screen operations are emoticon 1 and emoticon 3, respectively, and then puts emoticon 1 and emoticon 3 on the screen at the same time, and deletes the emoticon corresponding to the keyword "hmm" in the display area (emoticon 1 and emoticon 2), and deletes the emoticon corresponding to the keyword "ok" (emoticon 3), and updates the display area; as shown in FIG6c. The user can also select the emoticon corresponding to the keyword "OK", which will not be repeated here.

In an optional embodiment of the present invention, after obtaining the on-screen instruction based on the display area, an emoticon picture corresponding to the on-screen instruction can also be sent, and then the keyword corresponding to the emoticon picture on the on-screen is determined, and the emoticon picture corresponding to the keyword is deleted from the display area and the display area is updated; then the on-screen instruction based on the updated display area is obtained, and the emoticon picture corresponding to the on-screen instruction is sent.

In an optional embodiment of the present invention, if the input method does not obtain the on-screen instruction within a set time after starting to display the emoticon pictures, all emoticon pictures can be deleted; if the input method does not obtain the on-screen instruction again within a set time after obtaining the on-screen instruction, all emoticon pictures can also be deleted.

In an embodiment of the present invention, after displaying the emoticon picture, if there is more than one keyword, a screen-up instruction based on the display area can be obtained, and the emoticon picture corresponding to the screen-up instruction can be displayed on the screen; the keyword corresponding to the emoticon picture on the screen is determined, the emoticon picture corresponding to the keyword is deleted from the display area and the display area is updated; then the screen-up instruction based on the updated display area is obtained, and the emoticon picture corresponding to the screen-up instruction is displayed on the screen; thereby, the user can select emoticon pictures of multiple keywords through multiple screen-up operations, thereby improving the efficiency of selecting emoticon pictures corresponding to each keyword.
