Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
In order to solve the technical problem that the video watching experience of a user is low due to the fact that the user inconveniently views the explanation of a suspicious word or phrase in the process of watching a video in the related technology, the embodiment of the invention provides an information acquisition method, an information acquisition device, a terminal and a storage medium.
In a first aspect, an information obtaining method provided in an embodiment of the present invention is first explained.
As shown in fig. 1, an information obtaining method provided in an embodiment of the present invention may include the following steps:
and S110, playing the preset video.
The preset video carries corresponding preset subtitles, and the preset subtitles are correspondingly displayed on a playing interface of the preset video.
It is understood that the preset video may be any video in a video library.
In practical applications, when a user wants to watch a certain video, i.e. a preset video, the user can open a video player to watch the preset video. In order to facilitate the user to better understand the content of the preset video, the preset video usually carries the corresponding preset subtitle. It is understood that the preset video generally has a plurality of frames, and thus the preset subtitle generally has a plurality of frames. For different preset video frames, the corresponding preset subtitles may be the same or different, that is, the preset subtitles have a corresponding relationship with the preset video frames. Therefore, in the process of playing the preset video, the terminal can display the preset subtitle corresponding to the video frame being played in the playing interface.
For example, when playing a first video frame of a preset video, the terminal may display a preset subtitle corresponding to the first video frame in a playing interface. Similarly, when the terminal plays the second video frame of the preset video, the preset subtitle corresponding to the second video frame may be displayed in the play interface.
And S120, in the process of playing the preset video, detecting whether the current preset subtitle displayed on the current playing interface contains a target subtitle, wherein the target subtitle carries a preset identifier.
In the process of playing the preset video, the terminal can detect whether the current preset subtitle contains the target subtitle in real time, so that the target subtitle can be highlighted in the subsequent steps.
It should be noted that, the process of determining whether the current preset subtitle includes the target subtitle may be performed by a server, the server may perform word segmentation on the current preset subtitle through a word segmentation technology, and add a preset identifier to a word, a phrase, or a sentence obtained after the word segmentation, where the preset identifier may be determined according to an actual situation, and the embodiment of the present invention does not specifically limit the preset identifier. It can be understood that different target subtitles generally carry different preset identifiers.
For clarity of the description of the scheme, a detailed description will be given in the following embodiments of a manner in which the server obtains a target subtitle included in the preset subtitle and a preset identifier corresponding to the target subtitle.
And S130, when the current preset subtitle displayed on the current playing interface is detected to contain the target subtitle, highlighting the target subtitle.
When the terminal detects that the current preset subtitles contain the target subtitles, in order to enable a user to intuitively know that: the explanation of the target caption can be directly viewed in the video playing interface, and the target caption can be highlighted.
The manner of highlighting the target subtitle by the terminal may be as follows: and performing enlarged display on the target caption, or performing highlight display on the target caption, and the like. The embodiment of the present invention does not specifically limit the way in which the target subtitles are highlighted.
And S140, when receiving the triggering operation of the target caption by the user, acquiring target associated information corresponding to the target caption, wherein the target associated information is used for explaining the target caption.
When a user watches a video, if the target caption is puzzled or curious, a trigger operation may be performed on the target caption, where the trigger operation may include: click operation, double click operation, sliding operation and the like, and the embodiment of the invention does not specifically limit the trigger operation.
When the terminal receives the trigger operation of the target caption by the user, the terminal explains that the user wants to check the interpretation information of the target caption, so the terminal can obtain the target associated information corresponding to the target caption, and the target associated information can be used for interpreting the target caption.
For example, the preset subtitles are: the first noon war gives us a heavy attack. The target captions are: at noon war. When the terminal receives the triggering operation of the user on the target caption, the target associated information corresponding to the first-minute war can be searched, and the target associated information is used for introducing the first-minute war.
For another example, the preset subtitles are: what is desired is nice, perhaps everyone-to-one, and nice things never die. The target captions are also: what is desired is nice, perhaps everyone-to-one, and nice things never die. When the terminal receives a trigger operation of the user on the target caption, target associated information corresponding to the target caption may be searched, where the target associated information may be: the redemption of Shortsek. That is, "what is desired to be good, perhaps everyone-to-one, but good things never disappear" comes from "Shouchun's redemption".
The method for acquiring the target associated information corresponding to the target caption by the terminal can be roughly divided into two types.
The first mode is as follows: and after receiving the touch operation of the user on the target caption, sending a request to the server, and after receiving the request, the server can search the target associated information corresponding to the target caption and feed the target associated information back to the terminal.
The second way is: before receiving the touch operation of the user on the target caption, the terminal caches the target associated information corresponding to the target caption to the local terminal, so that the terminal can directly inquire the target associated information corresponding to the target caption locally.
And S150, displaying the target associated information on the current playing interface.
When the target associated information corresponding to the target caption is displayed on the current playing interface, the user can visually see the interpretation information corresponding to the target caption. And the interpretation information of the target caption needs to be switched to other application programs to be checked, so that the video watching experience of the user is improved.
The display position of the target related information on the current playing interface may be determined according to an actual situation, for example, the target related information may be displayed below, above, on the left side, on the right side, or the like of the target subtitle, or may be displayed in an area where no picture exists in the current playing interface, so as to prevent the target related information from blocking the picture in the playing interface. The display position of the target associated information on the current playing interface is not specifically limited in the embodiment of the present invention.
Therefore, according to the technical scheme provided by the embodiment of the invention, when a user watches a video, if the user wants to check the confused words or phrases in the caption, the user can directly click and other trigger operations on the confused words or phrases, so that the explanation information of the confused words or phrases can be seen on the current playing interface, and the user does not need to switch to other application programs to check the explanation of the confused words or phrases like the related technology, thereby improving the video watching experience of the user.
In order to more quickly and accurately determine whether the current preset subtitle displayed on the current playing interface includes a target subtitle, on the basis of the embodiment shown in fig. 1, in an implementation manner, before detecting whether the current preset subtitle displayed on the current playing interface includes the target subtitle, the information obtaining method may further include:
and acquiring a target subtitle included in the preset subtitle and a preset identifier corresponding to the target subtitle from the server.
As can be seen from the above description, for a preset subtitle, the target subtitle included in the preset subtitle may be the preset subtitle, or may be a word or a phrase in the preset subtitle. When it is determined which target subtitles are included in the preset subtitles, the preset subtitles need to be analyzed, and time and performance need to be consumed when the preset subtitles are analyzed. Therefore, in order to prevent the preset video from being influenced by the analysis of the preset subtitles, the terminal may not analyze the preset subtitles, but analyze the preset subtitles by the server. Specifically, for a preset video, before the preset video is played, the server may analyze preset subtitles of the preset video in advance to obtain target subtitles included in the preset subtitles, and add a preset identifier to each target subtitle.
Specifically, the method for obtaining the target subtitle included in the preset subtitle and the preset identifier corresponding to the target subtitle by the server, as shown in fig. 2, may include the following steps:
and S210, acquiring a preset subtitle and a pre-constructed knowledge database.
For a preset video, the preset video usually includes a plurality of video frames and a plurality of preset subtitles. Therefore, the server may extract each preset subtitle of the preset video and may combine each preset subtitle into text information, where each line of information in the text information may be one preset subtitle.
And the server can acquire a pre-constructed knowledge database so as to accurately analyze the preset subtitles in the subsequent steps.
S220, obtaining a to-be-processed statement in the preset subtitles, wherein the to-be-processed statement is any one of the preset subtitles.
After the preset subtitles corresponding to the preset video are obtained, each preset subtitle in the preset subtitles needs to be analyzed. Therefore, the terminal obtains the to-be-processed sentence in the preset subtitles, and the to-be-processed sentence can be any preset subtitle in the preset subtitles.
S230, judging whether the sentence to be processed is completely contained in the knowledge database, if so, executing the step S240, otherwise, executing the step S250.
After the terminal acquires the sentence to be processed, in order to determine whether the whole sentence to be processed is the target caption or the sentence to be processed needs word segmentation processing, the target caption is obtained. The terminal can judge whether the sentence to be processed is completely contained in the knowledge database.
And S240, taking the sentence to be processed as a target caption, and adding a corresponding preset identifier to the target caption.
If the sentence to be processed is completely contained in the knowledge database, the sentence to be processed is wholly the target caption, so that the sentence to be processed can be used as the target caption, and the corresponding preset mark is added to the target caption.
For example, assume that the to-be-processed statement is: what is desired is nice, perhaps everyone-to-one, and nice things never die. The sentence to be processed is completely contained in the knowledge database, and thus, the sentence to be processed can be used as a target caption.
And S250, performing word segmentation on the sentence to be processed to obtain each word segmentation, taking each word segmentation as a target caption, and adding a corresponding preset identifier to each target caption respectively.
If the sentence to be processed is not completely contained in the knowledge database, the sentence to be processed is not the target caption as a whole, so that word segmentation processing needs to be carried out on the sentence to be processed to obtain each word segmentation, each analysis is used as the target caption, and a corresponding target mark is added to each target caption.
For example, assume that the to-be-processed statement is: the first noon war gives us a heavy attack. After the words are divided in the sentence to be processed, two words of the first-noon war and the attack of the heavy pain can be obtained, so that the first-noon war and the attack of the heavy pain can be used as target subtitles, and target marks are added for the first-noon war and the attack of the heavy pain respectively.
In this embodiment, detecting whether the current preset subtitle displayed on the current playing interface includes a target subtitle may include:
judging whether the current preset subtitles displayed on the current playing interface contain subtitles with preset identifications or not;
and if the current preset subtitle contains the subtitle with the preset identifier, judging that the current preset subtitle contains the target subtitle.
And if the current preset subtitle does not contain the subtitle with the preset identifier, judging that the current preset subtitle does not contain the target subtitle.
Specifically, after the terminal obtains the target subtitles included in the preset subtitles and the preset identifications corresponding to the target subtitles from the terminal, the terminal can judge whether subtitles with the preset identifications are included in the current preset subtitles. If the current preset subtitle contains the subtitle with the preset identifier, the target subtitle contained in the current preset subtitle can be determined. If the current preset subtitle does not contain the subtitle with the preset identifier, it can be determined that the current preset subtitle does not contain the target subtitle.
Therefore, according to the technical scheme provided by the embodiment of the invention, when a user watches a video, if the user wants to check the confused words or phrases in the caption, the user can directly click and other trigger operations to see the explanation information of the confused words or phrases on the current playing interface, and the user does not need to switch to other application programs to check the explanation of the confused words or phrases like the related technology, and the user can not be influenced to watch the video normally, so that the video watching experience of the user is improved.
In order to find the target associated information corresponding to the target subtitle more quickly, on the basis of the foregoing embodiment, in an implementation manner, before the obtaining the target associated information corresponding to the target subtitle, the information obtaining method may further include:
acquiring index data corresponding to the preset subtitles from a server, wherein the index data is used for representing: and presetting the corresponding relation among the target subtitles included by the subtitles, the preset identification and the target associated information.
As can be seen from the above description, the server may obtain the target subtitles included in the preset subtitles, and add the preset identifier to each target subtitle. In addition, the server can inquire the target associated information corresponding to each target. And then, correspondingly storing the target caption, the preset identification and the target associated information, and further generating index data. The terminal can acquire the index data from the server in advance, so that after receiving the triggering operation of the target caption by the user, the terminal can search the target associated information locally and quickly.
At this time, the obtaining of the target associated information corresponding to the target subtitle may include:
and taking the preset identification corresponding to the target caption as a query index, and querying target associated information corresponding to the target caption in the index data.
The obtaining, by the server, index data corresponding to the preset subtitle may include:
for each target subtitle in the preset subtitles, searching target associated information corresponding to the target subtitle in a knowledge database;
and storing each target caption, the preset identification corresponding to the target caption and the target associated information corresponding to the target caption in an associated manner to obtain index data corresponding to the preset caption.
Therefore, according to the technical scheme provided by the embodiment of the invention, when a user watches a video, if the user wants to check the confused words or phrases in the caption, the user can directly click and other trigger operations to see the explanation information of the confused words or phrases on the current playing interface, and the user does not need to switch to other application programs to check the explanation of the confused words or phrases like the related technology, and the user can not be influenced to watch the video normally, so that the video watching experience of the user is improved.
For the purpose of describing the request, the following describes in detail the architecture of the information acquisition system of an embodiment of the present invention, as shown in fig. 3.
As can be seen from fig. 3, the information acquiring system provided in the embodiment of the present invention may include: a terminal 310 and a server 320.
The server 320 executes the step S301, and performs word segmentation on the preset subtitles to obtain target subtitles included in the preset subtitles; adding a preset identifier for a target caption, and searching target associated information corresponding to the target caption; and generating index data corresponding to the preset subtitles based on the target subtitles, the preset identification and the target associated information.
The terminal 310 executes step S302, and acquires a target subtitle included in the preset subtitle and a preset identifier corresponding to the target subtitle from the server 320; and acquiring index data corresponding to the preset subtitles.
The terminal 310 executes step S303, plays the preset video, and detects whether the current preset subtitle displayed on the current playing interface includes the target subtitle in the process of playing the preset video.
The terminal 310 executes step S304, and when it is detected that the current preset subtitle displayed on the current playing interface includes the target subtitle, the target subtitle is highlighted.
The terminal 310 executes the step S305, and when receiving a trigger operation of a user on a target subtitle, acquires target associated information corresponding to the target subtitle; and displaying the target associated information on the current playing interface.
It should be noted that, since the above steps have been described in detail in the above method embodiments, they are not described herein again.
Therefore, according to the technical scheme provided by the embodiment of the invention, when a user watches a video, if the user wants to check the confused words or phrases in the caption, the user can directly click and other trigger operations on the confused words or phrases, so that the explanation information of the confused words or phrases can be seen on the current playing interface, and the user does not need to switch to other application programs to check the explanation of the confused words or phrases like the related technology, thereby improving the video watching experience of the user.
