Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be described and illustrated below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments provided in the present application without any inventive step are within the scope of protection of the present application.
It will be appreciated that such a development effort might be complex and tedious, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure, and is not intended to limit the scope of this disclosure.
Example one
The embodiment provides a search processing method suitable for split screen, and aims to solve the problem that in the related art, the relevance between the search item with the front rank and the video is low. Fig. 1 is a flowchart of a search processing method suitable for split screen in an embodiment of the present application, and as shown in fig. 1, the method includes steps S101 to S105.
It is worth mentioning that the steps of the method are performed on the basis of the execution device. Specifically, the execution device may be a server, a cloud server, a client, a processor, or the like, but the execution device is not limited to the above type.
And step S101, obtaining a search initial result based on the search phrase. The search phrase may include more than one search word and/or more than one search word, and is not specifically limited herein; the searching step is performed based on a corresponding database by using the existing searching method, which is the prior art and will not be described in detail herein; the initial search result comprises a search item, and it can be understood that the search item can be a link, but can be presented in a title manner, and by clicking the search item, the page corresponding to the link can be jumped to; the first relevance of the search item and the search phrase is in positive feedback with the rank of the search item, and the calculation mode of the first relevance is related to the search mode used in the step, namely the higher the first relevance of the search item and the search phrase is, the higher the rank of the search item is.
Step S102, determining whether there is a played video, if yes, executing step S103 to step S105. The execution order of step S101 and step S102 is not limited herein. It can be understood that the video should be played last in a preset time period before the user performs the keyword-based search, that is, the time when the user performs the keyword-based search may be the starting time of the preset time period, and the duration of the preset time period may be adjusted according to the actual situation.
And step S103, acquiring a label phrase of the video. The tagged phrases may include a basic phrase, where the basic phrase includes any one or more of a video name phrase, a video type phrase, a video introduction phrase, a participant phrase, and a publishing source phrase.
And step S104, marking the N search items at the front of the ranking as mark items, and respectively calculating the second association degree of each mark item and the label phrase. The value N can be adapted to the actual situation, and the top page of the search result preferably has N search entries.
It can be understood that the object of the second relevance calculation is the relationship between the tag phrase and the tag entry, and it should be noted herein that the second relevance calculation may adopt the first relevance calculation mode, or may adopt other existing calculation modes, such as Text Ranku algorithm, TF-IDF value algorithm, LDA model, and the like, and is not limited herein, as long as the relevance between each tag entry and the tag phrase can be determined.
And step S105, updating the ranking of the label entry according to the second relevance to obtain a search result. The first N search items in the search results obtained by the step are ranked based on the first relevance, and the search items after the N +1 search items are ranked based on the second relevance.
And the rank of the updated mark entry is in positive feedback with the second relevance, namely, the larger the second relevance between the mark entry and the search phrase is, the more front the rank of the search entry is. For example: the search phrase is white, if the user watches TV play of the warring country type, the marked items can be ranked according to the white relevance of the historical characters; if the user is watching a game-type video, the tag entries may be ranked according to their degree of association with the game piece whites.
In summary, because the label phrase is related to the played video, the relevance of the label entry in the search result and the video is higher, so that the accuracy of the search result is improved, the manual screening time after the search result is obtained is reduced, and the overall efficiency is improved; the N marked entries are subjected to ranking updating, so that ranking updating is performed instead of all search entries, the number of processed samples is reduced, the processing efficiency is improved, and the running memory is reduced.
As an optional technical solution, the method may be applied to a smart television, and when the execution device executes the method, the smart television displays at least a play page corresponding to the video and a search page corresponding to the initial search result, and the play page and the search page are independent of each other.
Specifically, the smart television has a screen splitting function, and can be split into at least two split screens for display according to a screen splitting request, wherein the screen splitting request can be a starting request, namely, the smart television enters a screen splitting state after being started; the screen splitting request can also be generated based on a screen splitting dialog box, namely, a screen splitting item of the screen splitting dialog box is selected and then enters a screen splitting state; the screen splitting request can be generated based on a screen splitting button of the remote controller, namely the screen splitting button of the remote controller is clicked, and the smart television enters a screen splitting state; the split screen request may also be generated based on a voice recognizer, that is, a user makes a command through voice to enable the smart television to enter the split screen state, and of course, the generation of the split screen request may not be limited to the above type. Correspondingly, the smart television also has a split screen cancellation function, and reference may be specifically made to the relevant description of the split screen request.
It should be noted that, by adopting the split-screen setting, the smart television can simultaneously display the play page and the search page, and the duration of the preset time period in the step S102 may be set to be zero. Therefore, the user watches the video based on the playing page by utilizing one split screen in the split screen state, and can search based on the searching page by utilizing the other split screen, so that the related step of exiting playing software in the related technology can be omitted, the searching efficiency is improved, the watching of the video is not delayed in the searching process, and the user experience is improved.
It will be appreciated that the steps illustrated in the flowcharts described above or in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than here.
Example two
The second embodiment provides a search processing method suitable for split screen, and the second embodiment is performed on the basis of the first embodiment. The method is applied to the smart television, and the method may further include a search triggering step, where the search triggering step is performed before step S101.
Fig. 2 is a flowchart of a search triggering step shown in the second embodiment of the present application, and referring to fig. 1 and fig. 2, the search triggering step may include steps S201 to S203.
Step S201, receiving a trigger signal, and responding to the trigger signal to control a display screen to display a search dialog box. The trigger signal may be generated based on a search button of a remote controller or based on a speech recognizer, and the specific manner is not limited as long as the trigger signal is actively selected by a user. It is understood that the search dialog box may be suspended on the sub-screen where the page is played, or may be suspended on other sub-screens.
Step S202, generating a search request based on the search dialog box. The search request carries a search phrase. Specifically, the user may enter a search by entering a search phrase in a search dialog and clicking on certain items of the search dialog.
And step S203, responding to the search request, searching based on the search phrase and generating a search initial result. This step can be referred to in the prior art and is not described herein in detail. It should be noted that this step is implemented based on search software, and after the search dialog box is displayed in a pop-up manner, the smart television starts to load relevant data of the search software, and jumps to a search page after step S202.
In the technical scheme, the user actively selects to pop up the search dialog box, so that on one hand, the coverage rate of the whole screen can be ensured when the search is not performed, and on the other hand, the dialog box is popped up firstly and then the search dialog box jumps to the related search page of the search software, so that the related data of the search software is loaded within the input time period of the search phrase, the time for the user to independently wait for the loading of the related data of the search software is reduced, and the overall search efficiency is improved.
The technical solution can also be combined with the split screen setting in the first embodiment, specifically, after receiving the search request, the smart television can first determine whether the smart television is in the split screen state, and if so, can select any split screen except the playing page to skip the searching page, and execute step S203; if not, the smart television can be split to obtain more than two split screens, wherein at least one split screen displays a playing page corresponding to the video, and one split screen displays a searching page corresponding to the initial searching result. Preferably, when the split screen setting is performed, two split screens are preferably available.
As an optional technical solution, the search dialog box may further include a disassociation item, and accordingly, the method may further include a disassociation step, where the disassociation step may include: receiving an association release request, wherein the association release request is generated based on the release association item; the execution of step S105 is prohibited in response to the disassociation request, and then the initial search result is updated to the search result.
Through the technical scheme, as for the user only wants to search, namely the search is not related to the video, the user can release the relation between the playing page and the searching page through the release association item so as to meet various requirements of the user.
EXAMPLE III
The third embodiment provides a search processing method suitable for split screen, and the third embodiment is performed on the basis of the first embodiment and/or the second embodiment.
The tagged phrases obtained in step S103 may include real-time phrases in addition to the basic phrases. Fig. 3 is a flowchart of step S103 shown in the third embodiment of the present application, and referring to fig. 1 and fig. 3, step S103 may include step S301 to step S304.
And S301, inquiring basic phrases and search starting time of the video. The basic phrases have been described in the first embodiment, and are not described herein again. The search start time may be the on time of the playback software, the reception time of the trigger signal in step S201, or the reception time of the search request in step S202. However, considering the initiative of the client, the search start time is preferably the reception time of the trigger signal in step S201.
Step S302, the search start time is taken as the end time of the reference time period. It is understood that the duration of the reference time period can be adjusted according to actual conditions.
And step S303, acquiring subtitle characters and/or bullet screen characters of the video in the reference time period.
And S304, extracting keywords in the caption characters and/or the bullet caption characters and generating a real-time phrase. It should be noted that the method for extracting the keyword is not limited herein, and reference may be made to the method for extracting the basic phrase.
The basic phrase is the basic attribute of the video, which influences the search result on the basic attribute of the video, and the real-time phrase is the real-time characteristic of the video, which influences the search result on the real-time characteristic of the video, so that the search result has basic property and real-time property.
It should be noted here that, in the second relevance calculation, in terms of importance: real-time phrase > video type phrase > video name phrase > video introduction phrase > participant phrase > publishing source phrase.
As an optional technical solution, the calculating the second association degree between the arbitrary markup entry and the tag phrase in step S104 includes: intercepting a home page image of a mark entry; converting the home page image into home page characters; and calculating the association degree of the characters on the home page and the tag words and recording as a second association degree.
Because the content corresponding to the search item may be long, if the second relevance is calculated by adopting all the contents, the processing efficiency is affected, and therefore, only the home page is processed; because part of the search items are presented in the form of pictures, the images of the home page are selected and intercepted, and the texts are obtained and processed after character recognition is carried out on the basis of the images of the home page, so that the accuracy of the second relevance can be improved.
