Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In order to perform video search according to the degree of correlation between keywords input by a user and video content, the embodiment of the invention provides a video search method which is applied to a server. As shown in fig. 1, the method includes:
s101, obtaining keywords input by a user.
Specifically, the user may input a keyword in a search bar of the search page, where the input keyword may be a name of a movie or television work, a name of an art program, a name of an actor, a certain scene, or a certain line.
S102, when the keywords input by the user include preset condition keywords, searching videos containing first target scene labels matched with the keywords according to attribute information of the videos, and taking the videos as first target videos; the attribute information is obtained by statistics after scene identification is carried out on each video in advance, wherein the attribute information comprises scene labels of each scene of each video and timestamp information of a card segment corresponding to each scene label in the video.
In this embodiment, the preset condition keyword may be "scene", "lines", or "articles", etc. For example, the user inputs "say a movie of 'i love you' lines" in the search bar, and since the keyword includes a preset condition keyword "movie", a scene search should be performed to determine the first target video.
S103, first target timestamp information of a card segment corresponding to the first target scene label in the first target video is obtained.
And S104, determining the identification information of the first target video and the first target timestamp information as a search result.
In this step, the identification information of the first target video may include: the duration of the first target video and the video cover picture; if the first target video is a television show or a comprehensive art, the identification information may further include related information such as the number of episodes, the lead actor, and the like.
Since the content of each video is subjected to scene identification in advance and the identification result is counted to obtain the attribute information of each video, and the attribute information comprises the scene tags of each scene of each video and the timestamp information of the corresponding card segment of each scene tag in the video, after the user inputs the keyword, the video with the video content most matched with the keyword can be found for the user according to the matching degree of the keyword and the scene tags.
Fig. 2 is another schematic flow chart of a video search method according to an embodiment of the present invention. The video searching method is applied to a server and comprises the following steps as shown in the figure:
s201, obtaining a keyword input by a user.
S202, judging whether the keywords input by the user contain preset condition keywords or not; if yes, go to step S203; if not, step S206 is performed.
In a possible implementation manner, after a keyword input by a user is obtained, whether the keyword contains a preset condition keyword is further judged; if yes, carrying out scene search; if not, a regular search is conducted.
S203, searching the video containing the first target scene label matched with the keyword according to the attribute information of each video, and taking the video as the first target video.
As in step S102 in the embodiment shown in fig. 1, the attribute information is obtained by performing scene identification on each video in advance and then performing statistics, where the attribute information includes a scene tag of each scene of each video and timestamp information of a card segment corresponding to each scene tag in the video.
Illustratively, the keyword input by the user is the name a of an actor, and if a scene tag also includes the name a of the actor, the scene tag is considered to match the keyword, and the video containing the scene tag is the first target video.
The attribute information of the video may be specifically as shown in table 1:
TABLE 1
| Card segment identification | Scene | Line word | Character | Article with a cover | Time stamp information |
| 01 | Gunfight | Actor A | Automobile | 00:01:06—00:03:00 | |
| 02 | Embrace | I love you | Actor A and actor B | 01:00:00—01:02:00 | |
| 03 | Party with a mobile phone | Happy birthday | Actor C | Cake | 01:21:03—01:30:08 |
As shown in the above table, the scene tag corresponding to each card segment may include at least one of the four elements of a scene, a speech, a person, and an article. The scene labels of the card segment 01 are 'gunfight', 'actor A' and 'car', and are played at 00:01: 06-00: 03:00 in the video; the scene labels of the card segment 02 are 'hug', 'I love you', 'actor A' and 'actor B', and are played at 01:00: 00-01: 02:00 in the video; the scene labels of the clip segment 03 are "party", "happy birthday", "actor C", and "cake", which are played in the video at 01:21: 03-01: 30: 08.
S204, first target timestamp information of a card segment corresponding to the first target scene label in the first target video is obtained.
S205, the identification information of the first target video and the first target timestamp information are determined as the search result. After that, step S211 is executed.
S206, searching for a video containing a video title matching the keyword as a second target video.
In this step, when the keywords input by the user do not include the preset condition keywords, the performed conventional search is to perform video search according to the matching degree of the keywords and the video titles.
Illustratively, the keyword input by the user is the name a of an actor, and if the name a of the actor is also included in the title of a video, the video can be regarded as a second target video matching the keyword.
S207, judging whether each scene label of each second target video comprises a second target scene label matched with the user label; if yes, go to step S208; if not, step S210 is performed.
Specifically, the user tags may be obtained in advance according to scene tag statistics of videos watched by the user historically.
S208, second target timestamp information of the card segment corresponding to the second target scene label in the second target video is obtained.
S209, the identification information of the second target video and the second target timestamp information are determined as the search result. After that, step S211 is executed.
In steps S207 to S209, after the second target video is determined by the conventional search, if each scene tag of each searched second target video includes a second target scene tag matching the user tag, a video card segment meeting the preference of the user may be further recommended to the user, so that the user' S stickiness can be enhanced while the user click rate is increased.
In a possible implementation manner, the scene tags of the videos historically watched by the user are counted in advance, after the user tags are obtained, the statistical result of the scene tags of the videos historically watched by the user is further calculated, and the weight of each user tag is obtained.
If second target scene tags respectively matched with the multiple user tags exist in the scene tags of the second target videos, the timestamp information of the second target videos and the video card segments corresponding to the scene tags matched with the user tags in the second target videos can be used as search results according to the weight of each user tag, and the search results are displayed in the current page in a descending order.
For example, the user labels of the user a are "gun battle" and "hug", the weights of the two user labels are 0.8 and 0.2, respectively, the scene label of the second target video a is "gun battle" and "tiger", and the scene label of the second target video B is "car flight" and "hug". Although the scene tags of the second target videos a and B have second target scene tags respectively corresponding to the user tags, the second target video a should be ranked before the second target video B when the search result is displayed because the weight of the user tag "gun fight" is greater than "hug".
It should be understood that the search results which are more interesting to the user are arranged at the front position, so that the time for the user to obtain the video which the user wants to watch in the search results can be reduced, and the user experience is improved.
And S210, taking the identification information of the second target video as a search result.
And when the scene tags of the second target videos do not contain the scene tags matched with the user tags, directly taking the identification information of the second target videos as the search result and displaying the search result on the current page.
And S211, displaying the search result in the current page.
S212, detecting whether the user clicks the first target timestamp information, the first target video, the second target timestamp information or the second target video in the search result.
S213, playing the video selected by the user from the search results.
And when the fact that the user clicks the first target video or the second target video is detected, correspondingly playing the first target video or the second target video.
And when detecting that the user clicks the first target timestamp information or the second target timestamp information, skipping to the first target video or the second target video, and playing the card segment corresponding to the first target timestamp information or the card segment corresponding to the second target timestamp information according to the first target timestamp information or the second target timestamp information. In this way, the user can directly view the video card segment of interest without having to pull the progress bar of the video to find by himself.
Obviously, the video search method provided in the embodiment shown in fig. 2 can perform a conventional search or a scene search according to whether the keywords input by the user include preset condition keywords. On one hand, when the preset condition keywords are not contained, the conventional search is carried out, not only is the conventional search result displayed, but also card segments which are possibly interested by the user are recommended from the conventionally searched video according to the user tags, so that the user can quickly obtain the video content which is interested by the user from the returned massive videos, and the video recommendation method based on the user preference is realized; on the other hand, if the user has the specific video content to watch, the input keywords include the preset condition keywords, the timestamp information of the specific video content in the target video can be accurately provided for the user through scene search, the search result according with the preference of the user is returned, personalized video search service is provided for the user, and the user experience is further improved.
In addition, in the above embodiments, the video card segment and the corresponding scene tag may be determined after the server identifies the video content. In other embodiments, the user may intercept the video during playing, mark the scene tag, and store the scene tag locally or upload the scene tag to a server. The played video is not only the video searched by the user, but also the video selected to be played by the user from the video recommendation page.
The specific process is shown in fig. 3, and includes:
s301, in the video playing process, whether a user clicks a preset intercepting key is detected.
S302, when it is detected that the user clicks a preset intercepting key, taking the current frame when the user clicks the intercepting key as a starting frame.
And S303, when the preset intercepting key is detected to be clicked again by the user, taking the current frame when the intercepting key is clicked again by the user as a termination frame.
Specifically, the user may start video capture by clicking the up key and end video capture by clicking the up key again.
S304, intercepting video data between the starting frame and the ending frame from the playing video, obtaining a video card segment to be marked, and taking the time stamps of the starting frame and the ending frame as the time stamp information of the video card segment to be marked.
For example, if the timestamp of the start frame is 00:05:15 and the timestamp of the end frame is 00:06:10, then the corresponding timestamp information of the video card segment to be marked is 00:05: 15-00: 06: 10.
S305, receiving a scene label of the video card segment to be marked input by the user, and storing the scene label input by the user and the timestamp information of the video card segment to be marked into the attribute information of the played video.
In a possible implementation manner, after saving a scene tag input by a user and timestamp information of a video card segment to be marked, a message for inquiring whether the user collects the card segment to be marked is generated, and after the user confirms, the card segment to be marked intercepted by the user is collected into an account of the user.
Therefore, the user can intercept favorite card segments at any time in the video playing process and mark scene labels for the card segments independently, so that the user can search and watch the favorite card segments conveniently at any time.
