The components of the embodiments of the present disclosure, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be made by those skilled in the art based on the embodiments of this disclosure without making any inventive effort, are intended to be within the scope of this disclosure.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

For some media applications, a user may browse multimedia content through a client, and when the user browses multimedia content, the user may be interested in the currently browsed multimedia content, and a search requirement is generated, for example, as shown in fig. 1a, when the user browses the currently browsed multimedia content, if the user needs to watch other multimedia content related to the currently browsed multimedia content, the user may search by clicking on a search symbol in the upper right corner in fig. 1a, then manually input a search term in a search box shown in fig. 1b and then click on "search", so as to obtain other multimedia content related to the search term, and the other multimedia content obtained by searching in this way may not be a search result wanted by the user.

Based on the above-mentioned research, the information determining method provided in the embodiments of the present disclosure may extract, in advance, text information of a multimedia content for the multimedia content in the multimedia content library, and then combine the text information with search words in a history search request to jointly confirm search recommendation words associated with the multimedia content, because the text information of the multimedia content includes core content of the multimedia content, and the search words in the history search request may represent search words corresponding to the multimedia content in the history search request, when determining search recommendation words associated with the multimedia content based on the text information and the search words in the history search request, search recommendation words with higher accuracy corresponding to the multimedia content may be obtained, so if a user browses multimedia content at a client, the search recommendation words associated with the multimedia content may be sent to the client, thereby facilitating the user to quickly search for other multimedia content associated with the currently browsed multimedia content.

For the sake of understanding the present embodiment, first, a detailed description will be given of an information determining method disclosed in the present embodiment, where an execution body of the information determining method provided in the present embodiment is generally a computer device with a certain computing capability, such as a server.

The information determining method provided by the embodiment of the present disclosure will be described below by taking an execution subject as a server as an example.

Referring to fig. 2, a flowchart of an information determining method according to an embodiment of the present disclosure is shown, where the information determining method includes steps S201 to S203:

s201, extracting text information describing the multimedia content from the multimedia content library.

Here, a large amount of multimedia contents are stored in the multimedia content library, and extracting text information describing the multimedia contents may refer to extracting text information associated with each multimedia content. Specifically, the extraction may be performed in a mapping relationship table of multimedia content and text information stored in a multimedia content library, where each multimedia content and corresponding text information in the mapping relationship table may be established after the server receives the multimedia content uploaded by the client, for example, after the server receives the multimedia content uploaded by the client and the text information for describing the multimedia content, the server may store the multimedia content and the corresponding text information thereof correspondingly; alternatively, when the server receives the multimedia content, text information describing the multimedia content may be determined based on the multimedia content, and then the multimedia content and the corresponding text information may be stored correspondingly.

S202, determining search recommended words associated with the multimedia content based on the text information and the search words in the historical search request.

The search word in the history search request may be a search request sent to the server during the playing of the multimedia content by the plurality of clients or within a preset time after the playing of the multimedia content, where the search word is included in the search request and is used for searching the multimedia content.

And S203, associating the multimedia identification of the multimedia content with the search recommended word.

According to the method, after the search recommended words associated with each multimedia content can be obtained, the multimedia content and the search recommended words associated with the multimedia content are associated, and particularly when the association is carried out, the multimedia content and the search recommended words can be represented by the multimedia identification of the multimedia content and stored in an associated manner.

Because each obtained search recommended word associated with the multimedia content is obtained based on text information describing the multimedia content and historical search requests associated with the multimedia content, other multimedia contents more relevant to the multimedia content can be accurately and quickly searched when searching based on the search recommended word associated with the multimedia content.

The above information determining method provided in S201 to S203 may be used to determine, in advance, a search recommendation word associated with a multimedia content by extracting text information of the multimedia content in a multimedia content library and then combining the text information with a search word in a history search request, where the text information of the multimedia content includes core content of the multimedia content and the search word in the history search request may represent a search word corresponding to the multimedia content in the history search request, so when determining a search recommendation word associated with the multimedia content based on the text information and the search word in the history search request, a search recommendation word with higher accuracy corresponding to the multimedia content may be obtained, and if a user browses the multimedia content at a client, the search recommendation word associated with the multimedia content is sent to the client, thereby facilitating the user to quickly search for other multimedia content associated with the currently browsed multimedia content.

The above steps S201 to S203 will be described in detail below based on specific embodiments.

In one embodiment, for S202 described above, that is, when determining the search recommended word associated with the multimedia content based on the text information and the search word in the history search request, it may include:

(1) And searching a key identifier contained in the text information, and taking a word unit indicated by the key identifier as a core word unit in the text information.

Here, the core word unit in the text information refers to a word capable of representing the core content of the text information, and the core word unit is capable of representing the main core content of the multimedia content, for example, if a certain multimedia content is video content related to mango, the core word unit of the multimedia content may be mango.

The key identifier is used to identify the core word unit, and may be identified by "#" or "#" for example, and may be provided by the server side when the user publishes the media content on the media application, and the client selects to mark.

(2) Search words matched with the core word units are searched in search words in the historical search request and serve as search recommended words associated with the multimedia content.

After the core word unit is found, search words matching the core word unit may be further searched based on search words in the historical search request, thereby determining search recommended words associated with the multimedia content, and how to search, as will be explained later.

In another embodiment, for S202 described above, that is, when determining the search recommended word associated with the multimedia content based on the text information and the search word in the history search request, the method may further include:

(1) And performing word segmentation processing on the text information to obtain at least one word unit.

(2) Respectively calculating core indexes of the word units, and determining core word units from the word units based on the core indexes;

(3) Search words matched with the core word units are searched in search words in the historical search request words and serve as search recommended words associated with the multimedia content.

Here, in the case that it is determined that the key identifier does not exist in the text information, another manner of determining the core word unit is to determine the core word unit, specifically, the text information may include a plurality of word units, and word segmentation may be performed on the text information based on a pre-established word dictionary, then at least one word unit is obtained, for example, a plurality of word units are obtained, and then core indexes of the word unit segments are sequentially determined to determine the core word unit.

Specifically, before determining the core indexes corresponding to the word units respectively, word unit filtering may be performed to filter out stop words, that is, some words without practical meaning, and then the core indexes of the remaining word units are determined.

Specifically, when calculating the core indexes of the word units, respectively, and determining the core word units from the word units based on the core indexes, it may include:

(1) Calculating core indexes of the word units based on the number of times the word units appear in the multimedia content library and the number of times the word units appear in the multimedia content library;

(2) Based on the core index, word units are ordered, and word units with the number set before the ordering are used as core word units.

Specifically, when determining the core indexes of the remaining word units corresponding to any multimedia content, the core indexes corresponding to the word units can be determined according to the occurrence times of each word unit in the multimedia content library and the occurrence times of each word unit in the multimedia content library, wherein the multimedia content library can contain other multimedia contents except any multimedia content, for example, the multimedia content library can be all multimedia contents currently stored in a server, then the total occurrence times of each word unit in all multimedia contents are counted, then the occurrence times of each word unit in any multimedia content are counted, and then the core indexes corresponding to the word units can be represented by the ratio of the occurrence times of each word unit in any multimedia content to the total occurrence times of the word unit in the multimedia content library.

The process of determining the core word units based on the core indexes corresponding to at least one word unit respectively may be to sort the remaining word units in a descending order based on the core indexes corresponding to each remaining word unit after filtering out the stop word, and then use word units with a set number before sorting as core word units, for example, use word units with n bits before sorting as core word units, so as to obtain n core word units.

And N can be 1, for example, after word segmentation is performed on text information associated with the multimedia content and stop words are filtered, N word units are obtained, and if the core index of the 1 st word unit is greater than that of other word units, the 1 st word unit is used as the core word unit in the word units associated with the multimedia content.

Alternatively, n may be greater than 1, for example, if the pre-ordered set number of word units includes 3 word units, then the 3 word units may be used as core word units herein.

Also, after finding the core word unit in the text information in the second manner, search words matching the core word unit may be further searched based on search words in the historical search request, thereby determining search recommended words associated with the multimedia content, and how to search specifically will be described in detail herein below.

Specifically, searching the search word matched with the core word unit in the search words in the historical search request, when the search word is used as a search recommended word associated with the multimedia content, the method can specifically include:

(1) Searching search words containing core word units in search words in the historical search request to obtain at least one first candidate search recommended word;

(2) And determining the search recommended words based on the search times respectively corresponding to the first candidate search recommended words.

Here, the search word including at least one core word unit may be searched for as the first candidate search recommended word herein, for example, one of the core word units is "younger you", and if there are search words such as "younger you home" and "younger you director" in the history search request, "younger you home" and "younger you director" may be used as the first candidate search recommended word herein.

When determining the search recommended word based on the search times corresponding to the plurality of first candidate search recommended words, the plurality of first candidate search recommended words may be sorted in a descending order based on the search times, and then the first candidate search recommended words with the number set before sorting are directly used as the search recommended words herein.

In order to further obtain a search recommended word with high relevance to the multimedia content, in another implementation manner, the information determining method provided by the embodiment of the disclosure further includes:

(1) In the history search request, acquiring a target history search request triggered in the playing process of the multimedia content;

(2) At least one second candidate search recommended word associated with the multimedia content among the search words of the target historical search request is determined.

The target historical search request refers to a historical search request triggered by a user in the playing process of the multimedia content or after completing playing of the multimedia content in a preset time, so that search words in the target historical search request are search words input by the user in the process of browsing the multimedia content, and therefore the possibility that the search words have association degrees with the multimedia content is high, and at least one second candidate search recommended word associated with the multimedia content can be determined in the search words in the target historical search request.

Specifically, when determining the second candidate search recommended word among the search words in the target history search request, the search word in the target history search request corresponding to the multimedia content in the playing process of the client may be directly used as the second candidate search recommended word herein, or a set condition may be added, for example, the search times corresponding to the search words of the target history search request are considered, the search words in the target history search request are sorted in a descending order based on the search times, and then the search words with the preset number before sorting are used as the second candidate search recommended word herein.

Among the search words of the target historical search request, the search word with the preset number before sorting is selected as the second candidate search recommended word, because the relevance between a certain search word contained in a large number of historical search requests generated in the process of playing the multimedia content and the multimedia content is larger, for example, a video segment with a certain multimedia content of 'peony', the search requirement is generated by a user in the process of playing the multimedia content, the probability is that the user wants to view the multimedia content related to 'peony', the search number of the search words corresponding to the multimedia content is higher, and therefore, the search word with the preset number before sorting is selected as the second candidate search recommended word based on the search number, namely, the search word with the higher relevance to the multimedia content is selected as the second candidate search recommended word, and meanwhile, the search word irrelevant to the multimedia content can be filtered.

After obtaining the second candidate search term, further, determining the search recommended term based on the search times corresponding to the first candidate search term respectively may include:

and determining search recommended words based on the search times corresponding to the first candidate search words and the search times of the second candidate search words.

Specifically, the plurality of first candidate search recommended words may be sorted in descending order based on the search times respectively corresponding to the plurality of first candidate search recommended words associated with the multimedia content, and similarly, the plurality of second candidate search recommended words may be sorted in descending order based on the search times respectively corresponding to the plurality of second candidate search recommended words of the multimedia content, and then the search word associated with the multimedia content may be determined based on the sorted first candidate search recommended words and the sorted second candidate search recommended words.

For example, the same search term may be selected from the first candidate search recommended term set before ranking and the second candidate search recommended term set before ranking as the search recommended term associated with the multimedia content, or the first candidate search recommended term and the second candidate search recommended term may be ranked in descending order based on the number of searches, so that the target candidate search recommended term set before ranking may be used as the search recommended term associated with the multimedia content.

In another implementation manner, the information determining method provided by the embodiment of the present disclosure may further include:

(2) Among the search terms of the target historical search request, search recommendation terms associated with the multimedia content are determined.

In this case, another way of determining the search recommended word associated with the multimedia content is provided, that is, in the history search request, the target history search request triggered by the playing process of the multimedia content or the playing completion time is firstly obtained, which is detailed above, and is not described in detail herein, then after the search word of the target history search request is obtained, the search word in the target history search request corresponding to the multimedia content in the client playing process can be directly used as the search recommended word herein, or a set condition, such as considering the search times corresponding to the search words of the target history search request, is added, and the search words in the target history search request are ordered in descending order based on the search times, and then the search word with the preset number before the ordering is used as the search recommended word herein.

This may be used to determine how to determine search recommendations associated with multimedia content, i.e., by a target historical search request corresponding to the multimedia content during historical play, in the event that text information associated with the multimedia content is not available.

After the search recommended word associated with the multimedia content is obtained, the multimedia identifier of the multimedia content and the search recommended word can be associated and stored.

In addition, the information determining method provided in the embodiment of the present disclosure, as shown in fig. 3, may further include the following steps S301 to S302.

S301, a search recommended word acquisition request sent by a client is received, and a multimedia identifier of multimedia content played by the client before the search recommended word acquisition request is triggered is acquired.

The Client (Client) or referred to as a Client herein refers to a program corresponding to a server and providing a local service for a Client, and is generally installed on a common Client, and needs to cooperate with the server to operate, for example, some application App, for example, the Client herein may be an App for video viewing.

The search recommendation word obtaining request sent by the client may be generated after the triggering of the search box by the triggering client and before the input of the search word in the search box, for example, for the client in fig. 4a, when the multimedia content being displayed by the client is a scene area, and the description text corresponding to the multimedia content is "five assorted stops in five most united states large urban areas in china", the search recommendation word obtaining request may be sent to the server after clicking the search identifier in the upper right corner of the page shown in fig. 4 a; or, as an alternative implementation manner of the embodiment of the present invention, each time the client switches to a new multimedia content, a search recommendation word acquisition request may also be sent to the client, where the search recommendation word acquisition request may include a multimedia identifier of the multimedia content played by the client before the search recommendation word acquisition request is triggered, for example, a multimedia identifier of the multimedia content showing a scene area, so that the server knows the multimedia content played by the client.

S302, determining search recommended words associated with the multimedia identifiers, and sending the search recommended words to the client for display.

In one embodiment, if the search recommendation word obtaining request is sent to the server after clicking the search identifier in the upper right corner of the page shown in fig. 4a, the client may be triggered to jump to the search result page shown in fig. 4b at the same time, that is, the search page where the search box is triggered to be opened, where the search box is used for displaying the search recommendation word sent by the server is received, for example, the search recommendation word sent by the server is "assorted-break sea landscape |assorted-break sea travel".

In another embodiment, in a case where the client triggers a search recommendation word acquisition request by switching to a new multimedia content, for example, when the client switches to the multimedia content as illustrated in fig. 4a, the server sends the search recommendation word associated with the multimedia content to the search result page that is illustrated by the client, as illustrated in fig. 4 c.

When the search recommended word associated with the multimedia content is determined in advance in an offline state, the search recommended word associated with the multimedia content may be determined directly according to the acquired multimedia identifier and the association relationship between the multimedia content and the search recommended word obtained in advance.

Of course, the server may also acquire the search recommended word associated with the multimedia identifier in an online manner, that is, after the server receives the search recommended word acquisition request sent by the client, the server searches the multimedia content associated with the multimedia identifier and the text information corresponding to the multimedia content in the multimedia content library based on the multimedia identifier of the multimedia content, and then determines the search recommended word associated with the multimedia content according to the text information and the search word in the historical search request.

In summary, for multimedia content in a multimedia content library, text information of the multimedia content can be extracted in advance, and then search recommended words associated with the multimedia content are jointly confirmed by combining the text information and search words in a history search request, because the text information of the multimedia content contains core content of the multimedia content, and the search words in the history search request can represent search words corresponding to the multimedia content in the history search request, when the search recommended words associated with the multimedia content are determined based on the text information and the search words in the history search request, the search recommended words with higher accuracy corresponding to the multimedia content can be obtained, and thus if a user browses the multimedia content at a client, the search recommended words associated with the multimedia content are sent to the client, so that the user can conveniently and quickly search other multimedia content related to the currently browsed multimedia content.

Further, if a search recommended word acquisition request exists in the client, a multimedia identifier associated with multimedia content played by the client before the search recommended word acquisition request is acquired by the client, namely, the multimedia content being watched by the user before the search recommended word acquisition is triggered is confirmed, then the acquired search recommended word associated with the multimedia identifier is sent to the client, so that the client can display the multimedia content.

As shown in fig. 5, the embodiment of the present disclosure further provides an information determining method, applied to a client, the information determining method including the following steps S501 to S502:

S501, responding to the triggering operation for the search box, and sending a search recommendation word acquisition request to a server, wherein the search recommendation word acquisition request comprises a multimedia identifier of the multimedia content currently played by the client.

The triggering operation for the search box may be triggered after clicking the search identifier in the upper right corner of the page shown in fig. 4a, and the triggering client jumps to the page shown in fig. 4 b; alternatively, the triggering operation of the search box may be triggered after the client switches to the new multimedia content, for example, when the client switches to the multimedia content as shown in fig. 4a, the triggering operation of the search box is triggered at the same time.

When the client receives the triggering operation for the search box, a search recommended word acquisition request can be generated and sent to the server, wherein the search recommended word acquisition request is used for acquiring a search recommended word associated with the multimedia content currently played by the client.

S502, receiving search recommended words which are sent by a server and are associated with the multimedia identifiers.

When the client receives the triggering operation for the search box, the search page where the search box is located is displayed to the user, wherein the search page can be the page shown in fig. 4b, and meanwhile, the search recommended word is displayed in the search box, or in another implementation manner, the search page can be the page shown in fig. 4c, and then the user can continue searching for a plurality of multimedia contents associated with the search recommended word based on the search recommended word, and the process does not need the user to manually input the search word again, so that the search efficiency is improved.
