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 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.

FIG. 1 is a flow diagram illustrating a method of finding a work, according to an exemplary embodiment, as shown in FIG. 1, including the steps of:

in step S11, the type ID of the work type of the work corresponding to the keyword of the query request and the keyword ID of the keyword are acquired.

The works corresponding to the keywords of the query request may be the works requested to be read or watched by the user, and the division of the types of the works may be performed according to the commonalities of the contents of the works, for example, the types of the works with background music may be divided into the types of the works with background music. The keywords of the works are words having substantial meaning for the content of the works, and if the background music of the works with the background music is sky city, the user can input a query request of sky city to search the works with the background music of sky city, and the sky city can be used as the keywords. The type ID and the keyword ID may be preset numerical values, each type ID corresponds to a type of work, and each keyword ID corresponds to a keyword.

In this step, after receiving a read work request sent by a reader who wants to view a work, a preset type ID corresponding to the work type identifier and a preset keyword ID corresponding to the keyword of the work may be obtained according to the keyword of the work and the work type identifier corresponding to the keyword of the query request in the request.

In step S12, the type ID and the keyword ID are combined in a splicing manner to obtain a global ID of the work corresponding to the keyword of the query request.

The global ID is obtained by splicing and combining the type ID and the keyword ID according to a splicing combination mode, is unique and represents the ID of the work in the index service.

In this step, after the type ID and the keyword ID are obtained, the type ID and the keyword ID may be combined in a splicing combination manner to obtain a global ID of a work corresponding to a keyword of the query request including the type ID and the keyword ID. For example, if the obtained type ID is 10101011 and the keyword ID is 11100101, the global ID obtained after the concatenation combination may be 1010101111100101, or may be concatenated in another manner, which is not limited in this embodiment.

In step S13, according to a pre-established inverted index, determining an index item including a global ID of a work corresponding to a keyword of the query request, where each index item of the inverted index includes a global ID and a storage address of the work corresponding to the global ID; the work corresponding to the global ID is the work corresponding to the type ID and the keyword ID used when the global ID is generated.

The pre-established inverted index is an index mode for searching records according to index values, and each item in the index table comprises an attribute value and the address of each record with the attribute value. In this step, each index entry in the pre-established inverted index may include a global ID and a storage address of a work corresponding to the global ID. The global ID may be an attribute value of the inverted index, and the storage address may be an address of a record of the inverted index. After the global ID is generated in step S12, the index entry including the global ID of the work corresponding to the keyword of the query request may be determined according to the inverted index established in advance.

In step S14, the work corresponding to the keyword of the query request is obtained from the storage address included in the determined index entry.

In this step, the work corresponding to the global ID may be found through the storage address in the determined index entry. And, the number of works corresponding to the keyword of the obtained query request may be one or more.

In the embodiment of the disclosure, since the global ID can represent the type ID and the keyword ID of the work, different types of works can be searched in one index service, compared with the prior art in which different types of works need to provide different index services, the method only needs to provide one index service, and the search of different types of works is effectively realized under the condition of reducing the occupation of server resources.

The method for finding a work provided by the embodiment of the present disclosure is described in detail below, and fig. 2 is another flowchart of the method for finding a work according to an exemplary embodiment, as shown in fig. 2, including the following steps:

in step S21, the type ID of the work type of the work corresponding to the keyword of the inquiry request and the keyword ID of the work keyword are acquired.

In this step, the work corresponding to the keyword of the query request may be a work that the user requests to read or view. Wherein the work type may include: a type of work with text labels, a type of work framed with the original work, a type of work with background music, a type of work using magic expression, and the like. The corresponding type ID may be preset for each type of work, for example, the type ID of the type of work with text labels may be preset to 1, the type ID of the type of work in the same frame with the original work may be preset to 2, the type ID of the type of work with background music may be preset to 3, and the type ID of the type of work using magic expression may be preset to 4. The preset type ID can form a table with the work type or the work type identification for subsequent query acquisition.

Wherein, the key words of the work are different according to the work or the type of the work, for example, the work with text labels, such as # king glory #, the key words can be 'king glory', such as # zhangsan and wangwu #, and the key words can be 'zhangsan and wangwwu'; the key words of the works in the same frame with the original works can be the names of the works of the original works or the names of actors in the original works, etc.; the key words of the composition with the background music can be the music name of the background music; the key word of the work using the magic expression may be the name of the magic expression. Similarly, a corresponding key ID may be preset for each key, and the key ID may be preset to 32-bit long integer data.

In this step, after receiving a request for reading a work sent by a reader who wants to view the work, a preset type ID and a keyword ID corresponding to the keyword and the work type identifier of the work corresponding to the keyword of the query request in the request may be obtained. The obtaining mode can be a table look-up mode.

In step S22, the type ID and the keyword ID are combined in a splicing manner to obtain a global ID of the work corresponding to the keyword of the query request.

In this step, after the type ID and the keyword ID are obtained, the type ID and the keyword ID may be spliced and combined in a splicing and combining manner to obtain a global ID of a work corresponding to a keyword of the query request including the type ID and the keyword ID. Specifically, the tail part of the type ID and the head part of the keyword ID may be spliced and combined to obtain the global ID of the work corresponding to the keyword of the query request including the type ID and the keyword ID; for example, if the type ID is 123 and the key ID is 5678, the tail of 123 is spliced with the head of 5678 to obtain a global ID of 1235678. Or splicing and combining the tail part of the keyword ID and the head part of the type ID to obtain the global ID of the work corresponding to the keyword of the query request comprising the type ID and the keyword ID; for example, after the tail of 5678 is spliced with the head of 123, the global ID is 5678123.

Alternatively, the type ID and the keyword ID may be combined by using a separator "|", for example, in a work with background music "liang zhu", if the type ID of the work type with background music is 100 and the ID of the keyword "liang zhu" is 6668, data in the form of "100 | 6668" may be obtained as the global ID of the work corresponding to the keyword of the query request by combining the type ID and the keyword ID. Or may be in other combinations, which are not listed here.

In step S23, according to a pre-established inverted index, determining an index item including a global ID of a work corresponding to a keyword of the query request, where each index item of the inverted index includes a global ID and a storage address of the work corresponding to the global ID; the work corresponding to the global ID is the work corresponding to the type ID and the keyword ID used when the global ID is generated.

The pre-established inverted index is an index mode for searching records according to index values, and each item in the index table comprises an attribute value and the address of each record with the attribute value. In this step, each index entry in the pre-established inverted index may include a global ID, where the global ID is an index value, and a storage address of a work corresponding to the global ID, where the storage address is an address of each record having the attribute value. After the global ID is generated in step S12, the index entry including the global ID of the work corresponding to the keyword of the query request may be determined according to the inverted index established in advance.

In step S24, the work corresponding to the keyword of the query request is obtained from the storage address included in the determined index entry.

In this step, the work corresponding to the global ID can be found through the storage address in the determined index entry.

In step S25, when there are a plurality of works corresponding to the keywords of the obtained query request, the works corresponding to the keywords of each obtained query request are sorted according to the predetermined attribute features of the works, so as to obtain the display order information of the works corresponding to the keywords of each obtained query request.

The attribute characteristics of the work can be a predicted click rate of the work, a click rate of the work or a correlation degree between the work and keywords, the predicted click rate is a ratio of a number of times that the work is clicked to play to the number of times that the work is displayed in a pre-estimated manner, the click rate is a ratio of the number of times that the work is clicked to play to the number of times that the work is clicked to play, the correlation degree between the work and the keywords represents a correlation degree between content of the work and the keywords, and a calculation method for applying the correlation degree can refer to the prior art, and details are not described herein. In this step, the searched works may be sorted according to one or more of the above-mentioned work attribute features of the works, and the display order of the obtained works is display order information. It can be understood that the global IDs corresponding to the searched works are the same global ID.

In step S26, the works corresponding to the keywords of each acquired query request and the presentation order information are sent to the client.

In this step, the works and the display sequence information corresponding to the keywords of each acquired query request may be sent to the client through a unified interface between the server and the client.

According to the technical scheme provided by the embodiment of the disclosure, the searched works can be sequenced according to the attribute characteristics of the works, so that the works displayed by the client are more popular with readers, and the experience is better.

Accordingly, there is also provided in an exemplary embodiment a flow chart of a method of index creation for a work, as shown in fig. 3, comprising:

in step S31, the type ID of the work type of the index work to be created and the key ID of the work key are acquired.

In this step, after receiving the works uploaded by the user, according to keywords of the uploaded works and the work type identifiers, a preset type ID corresponding to the work type identifiers and a preset keyword ID corresponding to the keywords may be obtained. The type ID corresponding to the work type identifier may be the work type identifier itself, or may be other data besides the work type identifier, for example, the type ID may also be 32-bit long integer data. For example, if the user uploads a work with background music of "Liangzhu", the ID corresponding to "Liangzhu" may be obtained, and the type ID of the type of the work with background music may be obtained.

In step S32, the type ID and the keyword ID are spliced and combined according to the splicing and combining manner, so as to obtain a global ID of the index work to be created.

In this step, after the type ID and the keyword ID of the index work to be created are obtained, the global ID of the index work to be created may be constructed based on the type ID and the keyword ID, and specifically, the tail of the type ID and the head of the keyword ID may be spliced and combined to obtain the global ID of the index work to be created including the type ID and the keyword ID; or splicing and combining the tail part of the key word ID and the head part of the type ID to obtain the global ID of the index work to be created, which comprises the type ID and the key word ID. For example, if the ID corresponding to the "bridge congratulatory message" is binary 10101110, and the type ID of the type of the work with background music is binary 10001001, the global ID of 1010111010001001 or 1000100110101110 can be obtained by concatenating 10101110 and 10001001.

Alternatively, optionally, the type ID and the keyword ID may also be combined by using the symbol "-", for example, for a work with background music "lianzhu", if the type ID of the work with background music is 1100, and the ID of the keyword "lianzhu" is 1010101, the data in the form of "1100-" 1010101 "may be obtained after combining the type ID and the keyword ID, and the data is used as the global ID of the index work to be created. Or may be in other combinations, which are not listed here.

In step S33, an inverted index is created with the constructed global ID and the storage address of the index work to be created as index items.

In this step, the global ID of the index work to be created may be used as an attribute value, and the storage address of the index work to be created may be used as a recorded address to form an index entry, and create an inverted index.

According to the technical scheme provided by the embodiment of the disclosure, as the global ID in the inverted index can reflect the type ID of the type of the work and the keyword ID of the keyword, namely the inverted index can contain the storage address and the global ID of the works of different types, compared with the prior art that the inverted index of each service contains the storage address of a work of one type, the scheme provided by the disclosure can contain the storage addresses of the works of various types under the condition of providing one index service, and occupied server resources are reduced.

In an exemplary embodiment, after the step of obtaining the type ID of the work type of the index work to be created and the keyword ID of the work keyword, if the keyword ID of the work keyword is not obtained, the keyword ID of the work keyword of the index work to be created is generated. When the keyword ID is generated, IDs other than the keyword IDs corresponding to all keywords in the work type may be generated according to the work type of the work corresponding to the keyword, for example, in the work with background music, the background music is new song ABC, and the keyword ABC does not have a corresponding keyword ID, and in this case, if the keyword ID of the keyword in the work with background music is 1 to 1000000, 1000001 may be created for the keyword ID of the keyword for the keyword.

Similarly, when a new work type is uploaded, IDs except type IDs corresponding to all types in the existing work types can be created, so that the development workload is small, and the labor cost is saved.
