Detailed Description
The following description of embodiments refers to the accompanying drawings, which illustrate specific embodiments in which the invention may be practiced.
Referring to fig. 1, a first embodiment of the present invention provides a copyright inventory management method, which specifically includes:
s1, acquiring a purchase contract and a sales contract of a copyright carrier, and determining a time node of copyright change of the carrier according to the purchase contract and the sales contract.
The rights carrier is specifically a work, and more specifically may be a book, a movie, or the like. For a work, a copyright operation company needs to make a purchase contract with an author of the work to obtain the copyright of the work, so that the copyright purchase content and the effective time are agreed, and after the copyright of the work is obtained, the copyright operation company makes a sales contract with a client to sell the copyright of the work to a third party user, so that the copyright purchase content and the effective time are agreed.
It should be noted that, regarding copyright, the stock may be increased at the time of purchase start and the time of sales end, the stock may be decreased at the time of purchase end and the time of sales start, and the stock may not be changed at any time other than the start date of purchase or sales, so that the date on which the change of copyright stock occurs is de-duplicated and referred to as a time node.
And acquiring time nodes of copyright changes in purchase contracts and sales contracts of the copyright carrier. For example, the validity period of the contracted purchasing rights in the purchasing contract of the rights carrier is from 1 st 2019 to 1 st 2022, the corresponding time nodes in the purchasing contract are from 1 st 2019 to 1 st 2022, and in the sales contract of the rights carrier, the sales time of the contracted rights is from 1 st 2020 to 1 st 2021, and the corresponding time nodes in the sales contract are 2020.01.01 and 2021.01.01.
S2, sequencing the time nodes according to the time sequence.
And after the corresponding time nodes after the purchase contract and the sales contract of the carrier are obtained, forming a time axis by the node nodes according to the time sequence.
Also, as described in the above example, the validity period of the contracted purchasing right in the purchasing contract of the copyright carrier is from 1 st in 2019 to 1 st in 2022, and the corresponding time nodes in the purchasing contract are from 1 st in 2019 to 1 st in 2022, and in the sales contract of the copyright carrier, the sales time of the contracted right is from 1 st in 2020 to 1 st in 2021, and the corresponding time nodes in the sales contract are 2020.01.01 and 2021.01.01. The above four time nodes are ordered by time to form a time axis, as shown in fig. 2.
S3, determining the stock storage content of the carrier copyright according to the sequenced time nodes, the copyright content of the purchase contract and the copyright content of the sales contract.
Specifically, the copyright inventory of a work includes four main feature items including rights, language, country/region, and authorized time period, wherein the rights, language, country/region have small enumeration number and small variation and are consistent among different copyrighted works, so that the rights, language, and country/region can be used as fixed configuration features. While the variable range of authorized times is large and can be considered as a non-fixed configuration feature.
Enumerating possible situations of each fixed configuration feature, determining the subordinate relation between each enumerated content, forming a structural tree, and encoding each enumerated content according to a set rule.
For example, for the rights item, it includes four primary items of reading, film and television, game and cartoon, wherein the game can be divided into desk game, hand game, PC game and other end game, and the hand game can be divided into network hand game, single hand game, PC game can be divided into PC network game and PC single machine game. The rights item structure tree shown in fig. 3 can thus be formed.
For language terms, they may include English, simplified Chinese, traditional Chinese, and the like.
To achieve storage compression while making the computer program queriable, all enumeration contents of each fixed configuration feature item are encoded, the parent-child relationships between the enumerations are represented in the form of prefixes, and the hierarchy is represented in encoded character long-reading. For example, in the dimension of the right item, R represents the full right item, every two digits represent a further hierarchy, R01 represents the game, R0101 represents the hand tour, R0101 contains prefixes R and R01, and the full right item games all contain the hand tour. If the hand tour is known to be available, only R01 or R with the R0101 or ancestor grade of the hand tour is required to be obtained.
The complete dimension combination coding condition indicates that the copyright is available when the language, the region and the father level of the 3 dimensions of the right item exist or the right item exists, and otherwise, the copyright is not available. For example, the inventory set is represented as { ALR01}, it is necessary to detect whether the copyright represented by the code A1LR0101 is available, the region A1 is a sub-level, the language L is L itself, and the rights item R0101 is R01 sub-level, so that it is known that the copyright is available.
There may be a crossover to inventory set elements, such as two items in inventory set { A1LR, AL1R } both containing the sub-level copyright of A1L 1R. This is to ensure that all available enumerations can be looked up while maximally compressing the memory space.
As shown in fig. 4, in a specific embodiment, the step S3 specifically includes:
S31, determining a time period for recording the copyright of the carrier according to the time axis.
Specifically, one purchase of the carrier copyright is recorded as one period, namely, one purchase is recorded as one period from a purchase start time node to a purchase end time node.
Referring to fig. 2, t1 to t4 show a period of a carrier right, if the saleable right in the time period t1 to t3 in fig. 2 should satisfy the saleable right in the time period t1 to t2 and the saleable right in the time period t2 to t3, if S (tm, tn) represents the stock condition of the carrier right in the time period tm and tn, and { X } represents the stock after sale, so S (t 1, t 3) =s (t 1, t 2) Σs (t 2, t 3) = { X }. Similarly, S (t 2, t 4) = { X }, S (t 1, t 4) = S (t 1, t 2) Σs (t 2, t 3) Σs (t 3, t 4), and thus S (t 1, t 4) = { X }.
Depending on the nature of the collection: Therefore, if x∈s (t 1, t 3), then x∈s (t 2, t 3) is constant, i.e. all the marketable cases in S (t 2, t 3) are found in S (t 1, t 3), so S (t 2, t 3) can be ignored during storage. Thus, only 3 sets are actually needed in fig. 2 to represent the inventory of the carrier in the time period t1-t4, namely, S (t 1, t 2), S (t 3, t 4), S (t 1, t 4), namely, the time period for recording the copyrights of the carrier is a first time period between t1-t2, a second time period between t3-t4, and a third time period between t1-t 4.
S32, calculating copyright inventory in each time period according to the purchase copyright and the sales copyright in each time period.
Specifically, the copyright inventory S (t 1, t 2) of the first period is calculated, the copyright inventory S (t 3, t 4) of the second period is recorded, and the copyright inventory S (t 1, t 4) of the third period is recorded.
The following describes in detail how to calculate the inventory over a period of time for two adjacent time nodes. In one embodiment, as shown in FIG. 5, calculating the inventory between adjacent amount of time nodes includes:
s321, determining the purchasing rights of the carrier in the time period of any two adjacent time nodes according to the purchasing contract.
Specifically, the purchase rights in any adjacent time node may be determined based on the date of validation of the rights recited in the purchase contract. Similarly, as described in the foregoing example, since the corresponding time nodes in the purchase contract are 1 st 2019 and 1 st 2022, if the purchased copyright is a whole language and whole rights item, it can be determined that the purchased copyright is a whole language and whole rights item in the time period from 1 st 2019 to 1 st 2020, and the purchased copyright is a whole language and whole rights item in the whole region in the time period from 1 st 2020 to 1 st 2021.
S322, determining the sales rights of the carrier in the time period of any two adjacent time nodes according to the sales contract.
Specifically, the sales rights in the period of the adjacent time node may be determined based on the sales rights, for example, the sales time of the contracted rights is 2020, 1 st to 2021, 1 st, it is possible to determine that the sales rights in the period of 1 st month 1 st year 2020 to 1 st month 1 st year 2021 are all languages and all rights items of the A1 region.
S323, determining the copyright inventory in the same time period according to the purchase copyright and the sales copyright in the same time period.
In one embodiment, as shown in fig. 6, calculating the inventory condition in two adjacent time nodes specifically includes:
SA1, determining fixed configuration attribute items needing to be split and attribute items not needing to be split according to purchase rights and sales rights in the time periods of the two adjacent time nodes;
Specifically, according to the specific content of each fixed configuration attribute item in the purchase copyright and the specific content of each fixed configuration attribute item in the sales copyright, for the same fixed configuration attribute item, if the specific content in the purchase copyright is the same as the specific content in the sales copyright, determining the fixed configuration attribute item as a non-split fixed configuration attribute item; and if the specific content in the purchase copyright is different from the specific content in the sales copyright, determining the fixed configuration item as a split fixed configuration attribute item.
For example, assuming that the purchase right is a full-area full-language full-right item of the carrier in a certain period, if the full-area a consists of A1, A2 and A3 and the full-language L consists of L1, L2 and L3, and the full-right item R consists of R1, R2 and R3, the purchase right of the carrier is ALR, and if the sales right of the carrier in the certain period is A1L1R, the specific content of the right item is R in the purchase right and the sales right, the fixed configuration attribute item of the right item is determined as a non-split fixed configuration attribute item, and the area item is a in the purchase right, the language item is L in the sales right, and the area item is A1, the purchase right content and the sales right content are different for the area item, and the purchase right content and the sales right content are different, so the area item and the language item are determined as fixed configuration attribute items that need to be split.
SA2, acquiring enumeration conditions of fixed configuration attribute items to be split, and combining the enumeration conditions of all the fixed configuration attribute items to be split to obtain a first combination list;
Specifically, if the whole region a is composed of A1, A2, A3, the whole language L is composed of L1, L2, L3, and the whole rights item R is composed of R1, R2, R3. And combining the enumeration conditions of the all-region item A and the all-language item L in pairs to obtain the FIG. 7.
SA3, acquiring a specific combination of fixed configuration attribute items to be split in sales rights, and deleting the specific combination and all parent-level combinations of the specific combination from the first combination list;
Since the sales rights content in the sales contract of the carrier is A1L1R, the specific content of the fixed configuration attribute item which needs to be split for the sales rights content is A1L1, and the cell A1L1 is deleted in the matrix first. This will also result in incomplete parent level of the entitlement, thus requiring deletion of the leftmost A1L, the uppermost AL1, and the upper left hand AL of the cell.
SA4, processing the rest combinations in the first combination list to obtain parent combinations of the rest combinations;
since a2l= { A2L1, A2L2, A2L3}, A2L1, A2L2, A2L3 are negligible in inventory.
The cell of which the leftmost column is not deleted is searched in the matrix, other cells of the same row are ignored at the same time, the cell of which the uppermost row is not deleted is searched, and other cells of the same column are ignored at the same time, so that the parent level combination A2L, A3L, AL and AL3 can be obtained.
SA5, combining the parent level combination and the attribute items which do not need to be split to obtain copyright inventory in the same time period.
The parent combination A2L, A3L, AL, AL3 is combined with the entitlement R to obtain the simplest inventory form { A2LR, A3LR, AL2R, AL3R }.
In the following description, the copyright inventory condition in the time period of two non-adjacent time nodes is calculated, as shown in fig. 8, in a specific embodiment, the two non-adjacent time nodes are respectively recorded as a first time node and a second time node, where the first time node precedes the second time node, and the method includes:
SB1, determining the node between the first time node and the second time node according to the time axis.
Specifically, the first time node may be a purchase start time, the second time node is a purchase end time, and nodes t2 and t3 are included between the purchase start time node t1 and the purchase end time node, as shown with reference to fig. 2.
SB2, according to the purchase contract and the sales contract, determining a fourth inventory condition between any two adjacent time nodes in the first time node and the second time node.
Specifically, the stock condition S (t 1, t 2) in the time period of t1-t2, the stock condition S (t 2, t 3) in the time period of t2-t3, and the stock condition S (t 3, t 4) in the time period of t3-t4 are calculated. The calculation of the inventory conditions in two adjacent time periods can be obtained by calculation according to the method described above, and thus will not be described in detail here.
SB3, obtaining the third inventory condition by summing the fourth inventory condition.
The time period of t1-t 3 is saleable in the time period of t1-t2 and in the time period of t 2-t 3, so S (t 1, t 3) =s (t 1, t 2) Σs (t 2, t 3) = { X }. Similarly, S (t 2, t 4) = { X }, S (t 1, t 4) = S (t 1, t 2) Σs (t 2, t 3) Σs (t 3, t 4) and thus S (t 1, t 4) = { X }.
S33, recording copyright inventory conditions of the carrier by utilizing the first time period and the corresponding first inventory conditions, the second time period and the corresponding second inventory conditions and the corresponding third time period and the corresponding third inventory conditions.
Specifically, depending on the nature of the collection: Therefore, if x∈s (t 1, t 3), then x∈s (t 2, t 3) is constant, i.e. all the marketable cases in S (t 2, t 3) are found in S (t 1, t 3), so S (t 2, t 3) can be ignored during storage. Thus only 3 sets are actually needed in fig. 2 to represent the inventory of the vector over the period t1-t4, i.e. S (t 1, t 2), S (t 3, t 4), S (t 1, t 4).
When the copyright inventory is stored according to the storage mode of the copyright inventory, if the copyright inventory exists in a certain right R' within a time period tm-tn, only the existence of the copyright inventory is judgedSo that tx < = tm and tn < = ty and/>
The copyright inventory management method of the invention determines the time node of the change of the carrier copyright according to the purchase contract and the sales contract by determining the purchase contract and the sales contract of the carrier copyright, and determines the storage content of the copyright inventory according to the time node, the purchase contract content and the sales contract content. The storage method of the copyright inventory supports the inquiry and calculation of the product inventory with more dimensions, can greatly reduce the storage space and the complexity of calculation space and time, and can meet the real-time inventory acquisition in the copyright field.
Based on the first embodiment of the present invention, the second embodiment of the present invention provides a system for managing copyright and inventory of works, including: the system comprises a time node determining unit, a time axis determining unit and an inventory storage content determining unit, wherein the time node determining unit is used for acquiring a purchase contract and a sales contract of a copyright carrier and determining a time node of copyright change of the carrier according to the purchase contract and the sales contract; the time axis determining unit is used for sequencing the time nodes according to the time sequence to form a time axis; and the stock storage content determining unit is used for determining the stock storage content of the carrier copyright according to the time axis, the copyright content of the purchase contract and the copyright content of the sales contract.
