Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of computer technology, and more particularly, to a copyright overlap detection method and apparatus, a computer storage medium, and an electronic device. Background Art

[0002] This section is intended to provide a background or context to the embodiments of the disclosure that are recited in the claims, and no statement herein is admitted to be prior art by inclusion in this section.

[0003] On content platforms, a work's copyright for a particular category, such as a song's recording copyright, lyrics copyright, or music copyright, may be authorized by one or more copyright holders. Different copyright holders have different authorization ratios when granting authorization. For any work on a content platform, the total authorization ratios of all copyright holders must not exceed 100%. If the total authorization ratios exceed 100%, it indicates an authorization anomaly, which is copyright duplication.

[0004] In related technologies, in order to solve the copyright overlap problem, first, each authorization information in the authorization list is processed into structured table data, including the copyright holder ID, authorized content ID, authorization start date, authorization end date, authorization ratio of Class A rights, authorization ratio of Class B rights, etc.; then, each authorization information is expanded into n pieces of information to obtain one piece of authorization information corresponding to each day in the authorization time period, where n is the number of days from the authorization start date to the authorization end date; then, grouping is performed according to the authorized content ID and the specific authorization date, and the sum_result of the authorization ratio of a certain type of rights in each group is obtained; finally, data with sum_result greater than 100 is filtered to obtain data containing abnormal overlapping information, where each piece of data represents that the authorized content has copyright overlap on a certain type of rights on a specific authorization date. Summary of the Invention

[0005] However, in related technologies, on the one hand, when each piece of authorization information is expanded, the amount of data will be greatly increased, resulting in increasing storage and computing costs; on the other hand, the result obtained is each date where copyright overlap occurs.

[0074] The principles and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided solely to enable those skilled in the art to better understand and implement the present disclosure, and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided to make the present disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0075] Those skilled in the art will appreciate that the embodiments of the present disclosure may be implemented as a system, apparatus, device, method, or computer program product. Therefore, the present disclosure may be implemented in the following forms: entirely in hardware, entirely in software (including firmware, resident software, microcode, etc.), or in a combination of hardware and software.

[0076] According to an embodiment of the present disclosure, a copyright overlap detection method, a copyright overlap detection device, a computer storage medium, and an electronic device are provided.

[0077] In this article, it is important to understand that the terms involved are explained as follows:

[0078] Copyright overlap: A certain type of copyright of a work, such as the recording copyright, lyrics copyright, and music copyright of a song, may be authorized by one or more copyright holders. Different copyright holders have different authorization ratios. Normally, the sum of the authorization ratios of all copyright holders for a certain type of copyright of a work does not exceed 100%. When it exceeds 100%, it indicates that there is an abnormality in the authorization information, which is called copyright overlap.

[0079] Authorization List: This records the copyright holder's authorization information for a work, including the authorization period and authorization ratio. For example, the authorization list might include Company A authorizing a song to Platform A, with the authorization start date being January 1, 2020, and the authorization end date being December 31, 2025. The authorization ratio for the sound recording is 100%, the lyrics is 50%, and the music is 50%.

[0080] In this document, any number of elements in the drawings is for illustration and not for limitation, and any naming is for distinction only and does not have any limiting meaning.

[0081] The principles and spirit of the present disclosure are described in detail below with reference to several representative embodiments of the present disclosure. SUMMARY OF THE INVENTION

[0083] The inventors discovered that when performing copyright overlap detection, in the related art, first, each piece of authorization information in the authorization list is processed into structured table data, including the copyright holder ID, the authorized content ID, the authorization start date, the authorization end date, the authorization ratio of Class A rights, the authorization ratio of Class B rights, etc.; then, each piece of authorization information is expanded into n pieces of information to obtain one piece of authorization information corresponding to each day in the authorization time period, where n is the number of days from the authorization start date to the authorization end date; then, grouping is performed according to the authorized content ID and the specific authorization date, and the sum_result of the authorization ratios of a certain type of rights in each group is obtained; finally, data with sum_result greater than 100 is filtered to obtain data containing abnormal overlapping information, where each piece of data represents that the authorized content has copyright overlap on a certain type of rights on a specific authorization date. When each piece of authorization information is expanded, the amount of data will be greatly increased, resulting in increasing storage and computing costs. The result is that for each date where copyright overlap occurs, in actual business scenarios, copyright overlap time is usually one or more continuous time periods. Converting each piece of data representing an overlapping date into an overlapping time period requires additional development and computing costs, resulting in low efficiency in detecting copyright overlap time periods.

[0084] In view of the above content, the basic idea of ​​the present disclosure is: according to each piece of authorization information, the authorization change date in the authorization information is obtained, and the authorization ratio and authorization change date in each piece of authorization information are used to obtain the authorization ratio change value corresponding to each authorization change date, and based on the authorization ratio change value, the authorization ratio cumulative value corresponding to the authorization change date is obtained, and the authorization change dates are grouped according to the authorization ratio cumulative value to obtain copyright overlapping groups, and within each group, the copyright overlapping time is obtained according to the authorization ratio cumulative value.

[0085] After introducing the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are described in detail below.

[0086] Exemplary Methods

[0087] The following combination Figure 1 A copyright overlap detection method according to an exemplary embodiment of the present disclosure is described below.

[0088] refer to Figure 1 , the copyright overlap detection method may include the following steps:

[0089] S110: Obtain a target authorization list, and obtain an authorization change date and an authorization ratio change value corresponding to the authorization change date based on authorization information in the target authorization list; wherein the authorization information includes at least authorization ratio information and authorization time information;

[0090] S120: Based on the authorization ratio change value, obtain the authorization ratio cumulative value corresponding to the authorization change date, and group the authorization change dates according to the authorization ratio cumulative value to obtain copyright overlap groups;

[0091] S130. In the copyright overlapping group, obtain the copyright overlapping time based on the cumulative value of the authorization ratio of the authorization change date.

[0092] In the copyright overlap detection method of the embodiment of the present disclosure, on the one hand, after obtaining the target authorization list, the authorization change date corresponding to each authorization information and the authorization ratio change value corresponding to the authorization change date are obtained according to each authorization information in the target authorization list. According to the authorization ratio change value, the authorization ratio cumulative value corresponding to each authorization change date is obtained, which solves the problem in the related art that each authorization information needs to be inflated according to the number of days between the authorization start date and the authorization end date, and reduces the amount of data required for calculation; on the other hand, after obtaining the authorization ratio cumulative value, the authorization change dates are grouped according to the authorization ratio cumulative value to obtain copyright overlap groups. In each copyright overlap group, the copyright overlap time is obtained based on the authorization ratio cumulative value of the authorization change date. The copyright overlap time is a continuous time period, which solves the problem in the related art that only each date where copyright overlap occurs can be obtained. In actual business scenarios, the data of each overlapping date needs to be converted into an overlapping time period, resulting in low efficiency in detecting copyright overlap time periods. This reduces the consumption of computing resources and improves the efficiency of copyright overlap detection.

[0093] In step S110, the target authorization list is obtained, and the authorization change date and the authorization ratio change value corresponding to the authorization change date are obtained according to the authorization information of the target authorization list; wherein the authorization information at least includes authorization ratio information and authorization time information.

[0094] The target authorization list may include one type of copyright or multiple types of copyright, which is not specifically limited in this example embodiment. When the target authorization list includes multiple types of copyright, each type of copyright can be detected separately according to the copyright detection method disclosed in the present invention. The target authorization list includes multiple authorization information, and each authorization information includes at least authorization ratio information and authorization time information. The authorization ratio information may include the authorization ratio of each copyright holder, and the authorization time information may include the authorization start date and the authorization end date. The authorization change date can be determined based on the authorization time information in each authorization information. The authorization ratio change value is the change value of the authorization ratio when the date is the authorization change date, compared with the authorization ratio of the previous date or the next date.

[0095] refer to Figure 2 As shown, obtaining the authorization change date and the authorization ratio change value corresponding to the authorization change date according to the authorization information of the target authorization list may include:

[0096] Step S210. According to the authorization end date in each piece of the authorization time information, obtain a date after the authorization ends, and determine the authorization start date, the authorization end date, and the date after the authorization ends as the authorization change date;

[0097] Step S220: According to the authorization change date and the authorization ratio information, obtain the authorization ratio change value corresponding to the authorization change date.

[0098] Below, step S210 and step S220 will be further explained and illustrated. Specifically, the authorization time information in each authorization information is obtained, and the date after the authorization ends is obtained according to the authorization end date in the authorization time information. For example, if the authorization time information in the authorization information is 2023.01.01-2023.09.01, it can be known that the authorization end date is 2023.09.01, and based on the authorization end date, it can be deduced that the date after the authorization ends is 2023.09.02. After obtaining the date after the authorization ends, the authorization start date, the authorization end date and the date after the authorization ends calculated according to the authorization end date in the authorization time information are determined as the authorization change date. After determining the authorization change date, the authorization ratio change value corresponding to the authorization change date can be determined according to the authorization ratio information in the authorization information.

[0099] After determining the authorization change date, the authorization ratio change value corresponding to each authorization change date can be determined in combination with the authorization ratio information in the authorization information. Figure 3 As shown, obtaining the authorization ratio change value corresponding to the authorization change date according to the authorization change date and the authorization ratio information may include:

[0100] Step S310. Determine the first authorization information corresponding to the authorization change date and the first authorization ratio included in the authorization ratio information in the first authorization information;

[0101] Step S320. When the authorization change date is the authorization start date in the first authorization information, the authorization ratio change value is the first authorization ratio;

[0102] Step S330. When the authorization change date is the authorization end date in the first authorization information, the authorization ratio change value is 0;

[0103] Step S340: When the authorization change date is a date later than the authorization end date in the first authorization information, the authorization ratio change value is a negative value of the first authorization ratio.

[0104] Below, step S310 to step S340 will be further explained and illustrated. Specifically, first, the first authorization information corresponding to the authorization change date is determined in the authorization information. When determining the first authorization information, it can be determined based on the authorization start date and the authorization end date in the authorization change date. After determining the first authorization information, the first authorization ratio included in the first authorization information is obtained. The authorization ratio is the authorization ratio from the authorization start date to the authorization end date. Therefore, when the authorization change date is the authorization start date, the authorization change ratio is the first authorization ratio; when the authorization change date is the authorization end date, the authorization ratio has not changed, that is, the authorization change ratio value is 0; when the authorization change date is a date after the authorization ends, the authorization ends and the authorization ratio becomes 0, that is, the authorization ratio change value is the negative value of the first authorization ratio.

[0105] For example, copyright holder A's authorization ratio for song A is 50%, and the authorization period is 2023.01.01-2023.09.01. The authorization change dates include: 2023.01.01, 2023.09.01, and 2023.09.02. For the authorization change date 2023.01.01, the authorization ratio increases, and the authorization ratio change value is 50%; for the authorization change date 2023.09.01, the authorization ratio does not change, and the authorization ratio change value is 0; for the authorization change date 2023.09.02, the authorization ratio becomes 0, and the authorization ratio change value is -50%.

[0106] In this embodiment, after determining the authorization change date and the authorization ratio change value corresponding to the authorization change date, the authorization time information in the authorization information can be expanded according to the authorization change date, and the authorization ratio information in the authorization information can be expanded according to the authorization ratio change value. Figure 4 As shown, after obtaining the authorization change date and the authorization ratio change value corresponding to the authorization change date, the copyright overlap detection method may further include:

[0107] Step S410. Expand the authorization time information of the authorization information using the authorization change date;

[0108] Step S420: Supplement the authorization ratio change value corresponding to the authorization change date into the authorization information to obtain expansion information corresponding to each piece of the authorization information.

[0109] Steps S410 and S420 are further explained and illustrated below. Specifically, the authorization time information of the authorization information is expanded using the authorization change date. The expanded authorization time information is transformed into three pieces of information: namely, the authorization change date is added to the authorization information; after adding the authorization change date to the authorization information, an authorization ratio change value may also be added to the authorization information, and the authorization ratio change value corresponding to the authorization change date is added to the authorization information. The three pieces of authorization information obtained after expanding the original authorization information can be referred to as the expanded information corresponding to the authorization information.

[0110] In this embodiment, in addition to using the authorization start date and the date after the authorization ends to expand the authorization information, the authorization end date is also used to expand the authorization information. When the authorization end date is used for expansion, since the authorization ratio change value corresponding to the authorization end date is 0, it can be ensured that the actual copyright overlap end date is recorded without affecting the accuracy of the authorization ratio cumulative value, thereby further improving the efficiency of copyright overlap detection.

[0111] Table 1 shows a target authorization list, which includes three pieces of authorization information.

[0112] Table 1 Target authorization list

[0113] Content ID Copyright holder Authorization ratio Authorization start date Authorization end date Song A First 50％ 2023.01.01 2023.01.09 Song A Second 60％ 2023.01.02 2023.01.05 Song A C 70％ 2023.01.08 2023.01.10

[0114] Taking the first authorization information in Table 1 as an example, in this first authorization information, the authorization change dates include 2023.01.01, 2023.01.09, and 2023.01.10. The authorization ratio change value corresponding to the authorization change date 2023.01.01 is 50%, the authorization ratio change value corresponding to the authorization change date 2023.01.09 is 0, and the authorization ratio change value corresponding to the authorization change date 2023.01.10 is -50%. After obtaining the authorization change date and the authorization ratio change value corresponding to the authorization change date, the authorization time information and the authorization ratio information in the authorization information are expanded using the authorization change date and the authorization ratio change value, respectively. Table 2 shows the expanded information obtained after the authorization information is expanded.

[0115] Table 2 Expansion information table

[0116]

[0117] In this embodiment, the authorization information is expanded only according to the authorization change date, rather than expanding the authorization information with each date from the authorization start date to the authorization end date as in the related art, thereby reducing the amount of data required for subsequent calculations.

[0118] In step S220, based on the authorization ratio change value, the authorization ratio cumulative value corresponding to the authorization change date is obtained, and the authorization change dates are grouped according to the authorization ratio cumulative value to obtain copyright overlapping groups.

[0119] In this embodiment, the authorization ratio cumulative value is obtained by adding the authorization ratio change values ​​of the first authorization change date before the authorization change date. Before obtaining the authorization ratio cumulative value, it is also necessary to sort the expansion information according to the authorization change date. Figure 5 As shown, based on the authorization ratio change value, obtaining the authorization ratio cumulative value corresponding to the authorization change date may include:

[0120] Step S510. Obtain the expansion information with the same authorization change date and the authorization ratio change value in the expansion information with the same authorization change date;

[0121] Step S520: Merge the authorization ratio change values ​​in the expansion information with the same authorization change date to obtain a first authorization ratio change value;

[0122] Step S530: Based on the first authorization ratio change value, obtain the authorization ratio cumulative value corresponding to the authorization change date.

[0123] Steps S510-S530 are further explained and illustrated below. Specifically, first, expansion information with the same authorization change date is obtained, and the authorization ratio change values ​​in the expansion information with the same authorization change date are merged to obtain a first authorization ratio change value. After obtaining the first authorization ratio change value, the cumulative authorization ratio value corresponding to each authorization change date is obtained based on the first authorization ratio change value.

[0124] Taking the expansion information shown in Table 2 as an example, there are two expansion information in Table 2 with the same authorization change date. Therefore, the two expansion information with the authorization change date of 2023.01.10 can be merged into one expansion information. After the merger, the authorization ratio change value of the expansion information with the authorization change date of 2023.01.10 is -50%+0=-50%.

[0125] For further reference, Figure 6 As shown, obtaining the authorization ratio cumulative value corresponding to the authorization change date based on the first authorization ratio change value may include:

[0126] Step S610. Sort the expansion information according to the authorization change date;

[0127] Step S620. Based on the sorting order, for any of the authorization change dates, obtain all first authorization change dates that are before the authorization change date;

[0128] Step S630. Obtain the authorization ratio cumulative value corresponding to the authorization change date according to the first authorization ratio change value corresponding to the first authorization change date;

[0129] When the first authorization change date does not exist before the authorization change date, the first authorization ratio change value corresponding to the authorization change date is the cumulative authorization ratio value corresponding to the authorization change date.

[0130] Below, step S610 to step S630 will be further explained and illustrated. Specifically, according to the authorization change date, each expansion information is sorted in chronological order. After the expansion information is sorted, according to the sorting order, for any authorization change date, the first authorization change date of all the expansion information sorted before the expansion information where the any authorization change date is located is obtained, and the authorization ratio cumulative value corresponding to the any authorization change date is obtained according to the first authorization ratio change value of the expansion information where the first authorization change date is located. However, when there is no other expansion information before the expansion information where the any authorization change date is located, that is, when the expansion information where the any authorization change date is located is ranked first in the sorting order, the first authorization ratio change value of the expansion information where the any authorization change date is located is its authorization ratio cumulative value.

[0131] Furthermore, obtaining the authorization ratio cumulative value corresponding to the authorization change date according to the first authorization ratio change value corresponding to the first authorization change date includes:

[0132] All the first authorization ratio change values ​​corresponding to the first authorization change date are added together to obtain the authorization ratio cumulative value corresponding to the authorization change date.

[0133] Specifically, after determining the expansion information that precedes the expansion information where any authorization change date is located, the first authorization ratio change values ​​of all expansion information that are sorted before the expansion information where any authorization change date is located are accumulated to obtain the authorization ratio cumulative value of any authorization change date.

[0134] Based on the expanded information in Table 2, the obtained cumulative value of the authorization ratio can be referred to Table 3, in which the content ID, copyright holder, authorization ratio, authorization start date, and authorization end date are omitted.

[0135] Table 3 Authorization ratio cumulative value table

[0136] Authorization Change Date Authorization ratio change value Sort Order Authorization ratio cumulative value 2023.01.01 50％ 1 50％ 2023.01.02 60％ 2 110％ 2023.01.05 0 3 110％ 2023.01.06 -60％ 4 50％ 2023.01.08 70％ 5 120％ 2023.01.09 0 6 120％ 2023.01.10 -50％ 7 70％ 2023.01.11 -70％ 8 0

[0137] After obtaining the cumulative value of the authorization ratio corresponding to each authorization change date, each expansion information can be marked according to the cumulative value of the authorization ratio and grouped according to the mark value. Figure 7 As shown, grouping the authorization change dates according to the cumulative authorization ratio to obtain copyright overlap groups may include:

[0138] Step S710. Mark the expansion information according to the cumulative value of the authorization ratio corresponding to the authorization change date to obtain a marking value;

[0139] Step S720: Group the expansion information according to the tag value of each piece of the expansion information to obtain the copyright overlapping group.

[0140] Steps S710 and S720 are further explained and illustrated below. Specifically, the expansion information is marked according to the cumulative authorization ratio corresponding to each authorization change date to obtain a marking value for each expansion information piece. The expansion information pieces are then grouped according to the marking value to obtain copyright overlap groups.

[0141] refer to Figure 8 As shown, marking the expansion information according to the cumulative value of the authorization ratio corresponding to the authorization change date to obtain a marking value may include:

[0142] Step S810: When the cumulative value of the authorization ratio of the expansion information exceeds a threshold, the mark value of the expansion information is 0;

[0143] Step S820: When the cumulative value of the authorization ratio of the expansion information does not exceed a threshold, the mark value of the expansion information is 1.

[0144] Steps S810 and S820 are further explained and illustrated below. Specifically, when the cumulative authorization ratio in the expansion information exceeds a threshold, the expansion information containing the cumulative authorization ratio is marked as 0; when the cumulative authorization ratio does not exceed the threshold, the expansion information containing the cumulative authorization ratio is marked as 1. The threshold is 100%.

[0145] After marking each expansion information, you can group it according to the mark value of each expansion information, refer to Figure 9 As shown, grouping the expansion information according to the tag value of each expansion information to obtain the copyright overlap group may include:

[0146] Step S910. For any of the expanded information, obtain the first expanded information located before any of the expanded information and the grouping information of the first expanded information;

[0147] Step S920: Obtain grouping information of any of the expanded information based on the grouping information of the first expanded information and the tag value of any of the expanded information; wherein, when the expanded information is the first expanded information, the grouping information of the expanded information is the tag value of the expanded information;

[0148] Step S930: Group the expansion information with the same grouping information into one group to obtain the copyright overlapping group.

[0149] Steps S910-S930 are further explained and illustrated below. Specifically, for any expanded information, the grouping information of the first expanded information preceding the expanded information is obtained. The expanded grouping information is obtained based on the grouping information of the first expanded information and the tag value of the expanded information. However, when the expanded information is located first, the grouping information of the expanded information is the tag value of the expanded information. After obtaining the grouping information of each expanded information, the expanded information with the same grouping information is grouped together to obtain a copyright overlap group.

[0150] Based on Table 3, the grouping information of each expansion information group is referred to Table 4.

[0151] Table 4 Grouping information table

[0152]

[0153] In step S230, in the copyright overlap group, the copyright overlap time is obtained based on the cumulative value of the authorization ratio of the authorization change date.

[0154] After obtaining the copyright overlap group, you can get the copyright overlap time in each copyright overlap group. Figure 10 As shown, in the copyright overlap group, the copyright overlap time is obtained based on the cumulative value of the authorization ratio of the authorization change date, which may include:

[0155] Step S1010. Obtain the authorization change date when the cumulative value of the authorization ratio in the copyright overlap group exceeds a threshold;

[0156] Step S1020. The minimum date among the authorization change dates in which the cumulative value of the authorization ratio exceeds the threshold is used as the copyright overlap start date;

[0157] Step S1030: The maximum date among the authorization change dates in which the cumulative value of the authorization ratio exceeds the threshold is used as the copyright overlap end date.

[0158] Steps S1010 to S1030 will be further explained and illustrated below. Specifically, in each copyright overlap group, the authorization change date for which the cumulative authorization ratio exceeds a threshold is obtained, the smallest date among the authorization change dates for which the cumulative authorization ratio exceeds the threshold is used as the copyright overlap start date for the copyright overlap group, and the largest date among the authorization change dates for which the cumulative authorization ratio exceeds the threshold is used as the copyright overlap end date for the copyright overlap group. Based on the copyright overlap start date and the copyright overlap end date, the copyright overlap time in each copyright overlap group is obtained.

[0159] In the present disclosure, by marking each expansion information and grouping them according to the mark value, it is ensured that when the cumulative value of the authorization ratio on a certain authorization change date does not exceed the threshold, it will enter a new group from the cumulative date of the authorization ratio, thereby ensuring that there is at most one continuous copyright overlap time in each group, thereby improving the efficiency of obtaining copyright overlap time.

[0160] In summary, the method provided by the present disclosure can be applied to detecting copyright overlap time. On the one hand, after obtaining the target authorization list, the authorization change date corresponding to each authorization information and the authorization ratio change value corresponding to the authorization change date are obtained based on each authorization information in the target authorization list. Based on the authorization ratio change value, the authorization ratio cumulative value corresponding to each authorization change date is obtained. This solves the problem in the related art that each authorization information needs to be expanded according to the number of days between the authorization start date and the authorization end date, reducing the amount of data required for calculation. On the other hand, after obtaining the authorization ratio cumulative value, the authorization change dates are grouped according to the authorization ratio cumulative value to obtain copyright overlap groups. In each copyright overlap group, the copyright overlap time is obtained based on the authorization ratio cumulative value of the authorization change date. The copyright overlap time is a continuous time period. This solves the problem in the related art that only each date where copyright overlap occurs can be obtained. In actual business scenarios, the data of each overlapping date needs to be converted into an overlapping time period, resulting in low efficiency in detecting copyright overlap time periods. This reduces the consumption of computing resources and improves the efficiency of copyright overlap detection.
