Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The method and the device aim to at least solve the technical problems that in the related technology, manual operation processes of a user are more and time is consumed, and further the efficiency of the user for obtaining the required information content is influenced. The embodiment provides an information recommendation method, as shown in fig. 1, applicable to server-side execution, and the method includes the following steps:
The video mainly targeted in this embodiment may be a video of a type explained by a video blogger, and the subtitle information of the video may include each subtitle text and a display time corresponding to each subtitle text, where the display time may include: the start time (start time) and duration (duration) of the subtitle text. For example, the subtitle information for the video may be in the form of a subtitle list, including: { subtitle 1, start time, duration }; { subtitle 2, start time, duration }; … ].
There may be various optional manners for the process of acquiring the video subtitle information in this embodiment, for example, the video is configured with corresponding subtitle information in advance, and the subtitle information may be directly acquired.
And 102, the server determines a subtitle text containing a preset keyword from the subtitle information, and acquires target display time corresponding to the subtitle text containing the preset keyword.
The preset keywords may be keywords related to videos or commodities that may need to be recommended, including some associated subjects or verbs or specific nouns. For example, keywords associated with videos that may need to be recommended include: "previous video", "video has been done before", "trained", "posture master" … ". Keywords associated with items that may need to be recommended include: [ "recommend", "green prickly ash jam", and "leg massager" …. If the preset keyword is a specific noun, there may be multiple strategies, for example, a user name of an author who has ten thousand followers in the video platform may be used as the preset keyword, a video title whose watching amount exceeds 1 ten thousand times may be used as the preset keyword, and the like.
In this embodiment, the preset keywords may be counted in the keyword document in advance, so that the keyword document is directly obtained for matching the preset keywords in the subsequent use.
The information to be recommended may be candidate recommendation information queried by a preset keyword (a preset keyword included in the video subtitle text), specifically, the information may be video information or commodity information, and the like, and the information may include a link.
The target display time may be display time corresponding to a subtitle text including a preset keyword, and the embodiment may identify video content information corresponding to the target display time in a video, so as to be used as a reference basis for selecting and determining recommended target information from information to be recommended.
And step 104, the server selects target information for determining recommendation from the information to be recommended according to the identified video content information.
The present embodiment may select information most relevant to the identified video content information from the information to be recommended as target information for determining recommendation. For example, video information most relevant to the identified video content information is selected from the video information to be recommended as the content for determining recommendation; or selecting the commodity information most related to the identified video content information from the commodity information to be recommended as the determined recommended content, and the like.
And 105, the server sends the determined recommended target information and the target display time to the client.
Further, when the client plays the video, the target information containing the link is displayed at the target display time.
For example, when the user watches the video played by the client, if the video blogger is mentioning the related content of the "previous video" in the video, since the client has received the target display time (the display time corresponding to the caption text containing the preset keyword of the "previous video") and the target information corresponding to the target display time (the video search is performed by using the keyword of the "previous video", and the video information of the "previous video" that the video blogger is mentioning is finally determined and obtained according to the video content information of the target display time), the target information containing the link (i.e., the video information of the "previous video") can be displayed at the target display time (i.e., the current time of the related content that the video blogger is mentioning the "previous video"), as shown in fig. 2. Thus, the user can directly jump to watch the video of the previous video by clicking the link.
By applying the technical scheme of the embodiment, the related content mentioned by the video blogger can be recommended to the user watching the video in time in the video playing process, so that the user can quickly select whether to view the related recommended content according to the actual requirement of the user. Compared with the related technology, the method and the device do not need to manually search or page for finding the related content of the video blogger currently mentioned in the video, can select to click the recommended target information (including the link), and can directly jump to the corresponding page, so that the operation time is saved, and the efficiency of obtaining the required information content by the user is improved.
Further, as a refinement and an extension of the foregoing embodiment, in order to fully describe a specific implementation process of the method of the present embodiment, the present embodiment provides a specific method as shown in fig. 3, where the method includes:
For this embodiment, if the server can directly obtain the subtitle information of the video, the process shown in step 203 may be skipped to. If the server cannot directly obtain the subtitle information of the video, an audio file of the video can be obtained for voice recognition, that is, the processes shown in steps 201 to 202 are performed. For example, a video may be used as an input, and an audio file of the video may be extracted using an FFmpeg tool, where FFmpeg is an open source computer program developed under the Linux platform that can be used to record, convert, and transform digital audio.
For example, an Automatic Speech Recognition (ASR) technique may be used to perform Speech Recognition on an audio file to obtain a caption list a of [ { caption 1, start time, duration }, { caption 2, start time, duration }, … ] as the caption information of the video.
For example, a keyword document (containing a large number of preset keywords) of a recommended video and a commodity is labeled in advance, and then the caption list a obtained in step 202 is compared with the keyword document to screen out a caption list B containing the preset keywords [ { caption x1 containing the preset keyword a1, start time, duration }, { caption x2 containing the preset keyword a2, start time, duration }, … ].
And 204a, the server identifies video content information corresponding to the target display time in the video.
In practical applications, if a video blogger refers to related contents such as "previous video", "recommended xxx good", etc. in a video, a video cover picture of the referred video or an article picture of the referred article will usually appear in the video at the same time. Thus, in order to accurately obtain such video content information, there may be a variety of options:
as an alternative, step 204a may specifically include: firstly, acquiring a video frame image corresponding to target display time in a video; and identifying the illustration in the video frame image based on an image identification technology. For example, the video frame image is cut according to the starting time and duration of the subtitle list B obtained in step 203, and then through image recognition, the video cover or the picture of the article, etc. in the image is recognized, and such an illustration usually exists in the form of a pip or a sticker.
As another alternative, step 204a may specifically include: firstly, acquiring a path of a picture-in-picture or sticker material used in video production; and obtaining the illustration corresponding to the target display time according to the path. For example, if the works are made and shared to the master station of the video platform by a specific tool of the video platform, the video information may also include picture-in-picture and sticker material paths used in making the video, so that the illustrations such as video covers or article pictures corresponding to the start time and the duration in the subtitle list B obtained in step 203 may be directly obtained through these paths, and further, an image recognition process is not required, thereby improving the accuracy of the determination of the illustrations.
And a step 204b parallel to the step 204a, the server side inquires information to be recommended related to the preset keyword.
For example, according to the preset keyword in the subtitle list B obtained in step 203, if the preset keyword is related to a video, the TOP10 (TOP 10) ranked video information related to the preset keyword may be queried, where each video information includes { video link, video title, video cover map } as the information to be recommended. And if the preset keyword is related to the commodity, the commodity information of TOP15 (TOP 15) of the rank related to the preset keyword can be inquired, and each commodity information comprises { commodity link, commodity title, commodity cover page }, and is used as the information to be recommended.
And step 205, the server selects target information for determining recommendation from information to be recommended related to preset keywords according to video content information corresponding to the target display time in the video.
Optionally, step 205 may specifically include: information that matches the illustration (the illustration obtained in step 204 a) is selected from the information to be recommended (the information obtained in step 204 b) as target information. For example, for the subtitle list B obtained in step 203, one piece of information is a subtitle text x including the keyword M, and the start time of the subtitle text x is 3: 11, duration 2 seconds. Identifying 3 in the video: 11 to 3: 13 (video covers or pictures of articles and the like), and inquiring information to be recommended related to the keywords M. Then, information matched with the illustration is selected from the information to be recommended, and the information is used as information required to be displayed in the video 3: 11 to 3: recommended content (i.e., target information for determining recommendation) displayed together with the video content during 13.
For example, the illustration may be a video cover illustration, and the information to be recommended may include: video information to be recommended, which may include: links, titles and cover drawings of videos to be recommended; correspondingly, the selecting information matched with the illustration from the information to be recommended as the target information may specifically include: and selecting target video information of which the video cover art (the art identified in the step 204 a) is matched with the cover art of the video to be recommended from the video information to be recommended as target information for determining recommendation. For example, the image similarity can be calculated, and one piece of video information with the highest similarity between the video cover art and the cover art of the video to be recommended is selected from the video information to be recommended and serves as the target video information for determining recommendation.
For example, the illustration may also be an article picture illustration, and the information to be recommended may include: the information of the goods to be recommended may include: the link, the title and the commodity map of the commodity to be recommended; correspondingly, the selecting information matched with the illustration from the information to be recommended as the target information may specifically include: and selecting target commodity information of which the commodity picture illustration (the illustration identified in the step 204 a) is matched with the commodity picture of the commodity to be recommended from the commodity information to be recommended as the target information for determining recommendation. For example, the image similarity may be calculated, and the item information with the highest similarity between the item image illustration and the item image of the item to be recommended is selected from the item information to be recommended as the target item information for determining recommendation.
And step 206, the server side sends the determined recommended target information and the target display time to the client side.
Further, when the client plays the video, the target information containing the link is displayed at the target display time.
For example, as shown in fig. 4, as a schematic flow of processing at the service end, a video may be used as an input, an audio file of the video is extracted, and subtitle information of the audio file is speech-recognized to generate a subtitle list a. And combining the keyword documents to screen out a subtitle list B containing the keywords of the recommended videos or the commodities. And then, according to the subtitle list B, the insertion pictures in the frame pictures at the corresponding moment can be acquired in parallel, and the video information or the commodity information related to the keywords can be retrieved. Finally, selecting one piece of video information with the highest similarity between the video cover art and the cover art of the video to be recommended from the video information to be recommended through picture similarity calculation, and returning the video information serving as target video information (including video links) for determining recommendation to the client; or selecting one commodity information with highest similarity between the commodity picture illustration in the to-be-recommended commodity information and the commodity picture of the to-be-recommended commodity, and returning the commodity information (including the commodity link) serving as the target commodity information for determining recommendation to the client.
Although there are recommendation algorithms that recommend relevant videos under the current video, the videos are usually other videos of the same type and not the exact videos or commodities currently mentioned by the video blogger. By the method provided by the embodiment, when a user watches a video, the user can directly watch corresponding video information or commodity information containing the link in the video when watching the video blogger mentions the previous video, the video is made before, and the xxx good object is recommended, so that the user does not need to exit the current page to search or turn pages to search, and can directly select the link to view, thereby effectively saving the operation time and improving the operation efficiency. And the convenient mode is added, so that the user can click the next video, and the active time of the user can be prolonged.
The content of the foregoing embodiment is a message processing procedure described at a server side, and further, to fully illustrate the implementation of this embodiment, this embodiment further provides another information recommendation method, which is applicable to a client side of a user terminal for execution. As shown in fig. 5, the method includes:
The target information may be selected from information to be recommended related to a preset keyword included in subtitle information of the video according to video content information corresponding to target display time in the video, and the target display time may be display time corresponding to a subtitle text including the preset keyword. For the determination process of the target information and the target display time, reference may be made to the embodiments shown in fig. 1 and fig. 3, and details are not repeated here.
And step 302, when the client plays the video, displaying the target information containing the link at the target display time.
Target information can be displayed in the video in the form of an interactive component, and a user can execute execution logic corresponding to the interactive component after clicking the interactive component, and then jump to a corresponding video page or a commodity page through a link.
Optionally, step 302 may specifically include: when the client plays the video, the target video information is displayed at the target display time, wherein the target video information may include: the links, titles and cover drawings of the videos are recommended.
For example, when the user watches the video played by the client, if the video blogger is mentioning the related content of "the video has been made before" in the video, since the client has received the target display time (the display time corresponding to the caption text containing the preset keyword of "the video has been made before") and the target video information corresponding to the target display time (the video information of "the video has been made before" is finally determined to be obtained by performing the video search using the keyword of "the video has been made before" and according to the video content information of the target display time), the target video information containing the link (i.e. the video information of "the video has been made before") can be displayed at the target display time (i.e. the current time when the video blogger is mentioning the related content of "the video has been made before"), specifically, the link, title, and cover art of the video may be included. Thus, the user can jump directly to watching the video of "this video has been done before" by clicking on the link.
Optionally, step 302 may specifically include: when the client plays the video, target commodity information is displayed in the target display time, wherein the target commodity information comprises: and recommending the link, the title and the commodity map of the commodity.
For example, when the user watches the video played by the client, if the video blogger is mentioning the relevant content of the green pepper sauce in the video, since the client receives the target display time (the display time corresponding to the caption text containing the preset keyword of the green pepper sauce) and the target video information corresponding to the target display time (the commodity search is carried out by using the keyword of the green pepper sauce, and the commodity information of the green pepper sauce mentioned by the video blogger is finally determined and obtained according to the video content information of the target display time), therefore, the target commodity information (namely the commodity information of the green pepper sauce) containing the link can be displayed at the target display time (namely the current time of the relevant content of the green pepper sauce which is being referred to by the video blogger), and particularly the link, the title and the commodity map of the commodity can be contained. Therefore, the user can directly jump to the commodity page of the green pepper sauce by clicking the link.
In this embodiment, in order to quickly guide the user to click the recommended target information for jumping, further optionally, step 302 may further include: and displaying guide information which can be selected by clicking while displaying the target information. For example, as shown in FIG. 6, a clicking finger may be added to the picture-in-picture display of the recommended video to guide the user to click to view the recommended video content. Through the optional mode, the user can be helped to quickly know the recommended video and can directly click and play the video, and the use experience of the user is improved.
The embodiment provides a scheme for automatically putting corresponding video links and commodity links on short videos, so that a consumer can conveniently click and jump when seeing the videos, and more convenient video or commodity viewing experience can be provided for the consumer. The playing amount of other related videos and the transaction amount of platform commodities can be improved, the viscosity and the use duration of a user are increased, and the commodity sale conversion rate is improved.
Further, as a specific implementation of the method shown in fig. 1 and fig. 3, the embodiment provides an information recommendation apparatus applicable to a service end side, as shown in fig. 7, the apparatus includes: an acquisition unit 41, a determination unit 42, a recognition unit 43, an inquiry unit 44, and a transmission unit 45.
An acquisition unit 41 configured to acquire subtitle information of a video;
a determining unit 42 configured to determine a subtitle text containing a preset keyword from the subtitle information;
the obtaining unit 41 is further configured to obtain a target display time corresponding to the subtitle text containing the preset keyword;
