FIG. 2 schematically shows a flow chart of a method of merchandise recommendation according to an embodiment of the present disclosure.
As shown in fig. 2, the method includes operations S210 to S260.
In operation S210, a set of repeat purchases of a first user is obtained.
According to an embodiment of the present disclosure, operation S210 may include, for example, acquiring historical purchase data of the first user in the e-commerce platform, determining commodities with a purchase frequency more than two times from the historical purchase data, then removing commodities with a low possibility of repeated purchase from the commodities, and grouping the remaining commodities into a repeatedly purchased commodity set.
In operation S220, a repeat purchase time range for repeatedly purchasing each item in the item set is determined.
According to an embodiment of the present disclosure, the time range in which the product is purchased again may be estimated according to the repeated purchase cycle (interval between two adjacent purchase times) of the product in the historical purchase data.
Based on this, operation S220 may include, for example, determining, for each item of the set of repeated purchases of the item, a sum of a largest repeated purchase period of the at least one repeated purchase period of the item and a most recent purchase time of the item as an upper bound of the repeated purchase time range, and a sum of a smallest repeated purchase period of the at least one repeated purchase period of the item and a most recent purchase time of the item as a lower bound of the repeated purchase time range.
In operation S230, it is determined that the goods whose repeat purchase time range does not include the current time in the repeat purchase goods set are the goods that need to be excluded.
According to an embodiment of the present disclosure, operation S230 may include, for example, determining that a repeat purchase time range for each item in the repeat purchase item set is compared with a current time. And if the current time is earlier than the lower limit of the repeated purchase time range or the current time is greater than the upper limit of the repeated purchase time range, taking the commodity as the commodity to be eliminated.
In operation S240, a preferred goods set of the first user is acquired.
According to an embodiment of the present disclosure, operation S240 may include, for example, obtaining goods frequently purchased by the first user (the number of purchases is greater than the threshold number of purchases) by analyzing historical purchase data of the first user, and grouping the goods into a preferred goods set of the user.
In operation S250, a set of goods to be recommended is determined according to the set of preferred goods and the goods to be excluded.
According to an embodiment of the present disclosure, operation S250 may include, for example, removing the item to be excluded from the set of preferred items, and obtaining a set of items to be recommended.
In operation S260, a set of goods to be recommended is output.
According to the embodiment of the disclosure, the output set of commodities to be recommended can be recommended to the first user, so that commodities required by the user can be recommended to the user more accurately, and the user experience is improved.
The method shown in fig. 2 is further described with reference to fig. 3-5 in conjunction with specific embodiments.
Firstly, determining the repeated purchase cycle of each commodity according to all commodity purchase data in an electronic commerce platform, and classifying all commodities into three categories according to the rule of the repeated purchase cycle: zero repeated purchase cycle, long repeated purchase cycle, short repeated purchase cycle, and the corresponding relation between each commodity and each category is stored.
Next, operation S210 is performed to obtain a set of repeatedly purchased goods of the first user.
FIG. 3 schematically shows an example flow diagram for obtaining a set of repeat purchases of items by a first user, in accordance with an embodiment of the disclosure.
As shown in fig. 3, operation S210 may include the following operations S310 to S330.
In operation S310, a plurality of original goods purchased by a first user within a preset time period are acquired.
According to the embodiment of the present disclosure, the commodity (i.e., the original commodity) purchased by the first user within the preset time period may be acquired by acquiring the purchase data of the first user within the preset time period. The preset time period may be a continuous time period or a discontinuous time period. Illustratively, the preset time period in the present embodiment is the last 1 year.
In operation S320, a repeat purchase cycle category of each of a plurality of original goods is determined.
According to embodiments of the present disclosure, the repeat purchase cycle categories may include, for example, a zero repeat purchase cycle, a long repeat purchase cycle, and a short repeat purchase cycle. The commodity with the zero repeated purchasing cycle refers to a commodity with a generally short repeated purchasing cycle, namely, a consumable such as a cotton swab and the like with frequent repeated purchasing. The commodity with a long repeated purchase cycle refers to an article with a repeated purchase cycle with a high probability of three years and more, such as a valuable article, a large household appliance, a diamond ring and the like. The commodity with a short repeated purchase cycle refers to a commodity with a repeated purchase frequency less than zero repeated purchase cycle, and the repeated purchase cycle is within three years, such as daily necessities such as skin care products.
According to the embodiment of the disclosure, the repeated purchase cycle type identifier Bp can be set to represent the repeated purchase cycle type of the commodity, and the value example of Bp is as follows:
Figure BDA0002252588430000081
in operation S330, the commodities, of which the repeat purchase cycle categories are zero repeat purchase cycles and short repeat purchase cycles, among the plurality of original commodities are grouped into a repeat purchase commodity set.
According to the embodiment of the disclosure, the commodities with the zero repeated purchase cycle and the commodities with the short repeated cycle in the original commodities are gathered to form a repeated purchase commodity set.
Next, operation S220 is performed to determine a repeat purchase time range for repeatedly purchasing each item in the item set.
FIG. 4 schematically illustrates an example flow chart for determining a repeat purchase time range for repeatedly purchasing items from a set of items according to an embodiment of this disclosure.
As shown in fig. 4, operation S220 may include, for example, the following operations S410 to S430.
In operation S410, a purchase time for repeatedly purchasing each item in the set of items is acquired.
According to embodiments of the present disclosure, data may be purchased through a first user's history within a last year in an e-commerce platform. The time for each purchase of each item in the set of repeatedly purchased items is obtained.
At least one repeat purchase cycle for each item is determined according to the purchase time of each item in operation S420.
According to an embodiment of the present disclosure, the repeat purchase cycle of each type of goods of the first user may be calculated according to the following formula:
Figure BDA0002252588430000091
wherein, PtA repeated purchase cycle for the user to repeatedly purchase the commodities for the tth time; t ist+1Time to purchase the class of merchandise for the t +1 th time of the user; t istTime to purchase the item for the user for the tth time; vtThe unit volume of the commodities purchased when the commodities are purchased for the t time; qtThe purchase amount of the goods when purchasing the goods for the t-th time. According to an embodiment of the present disclosure, PtThe unit of (b) may be, for example, 1 day.
For example, the minimum value Bpw is selected from the repeat purchase cycle calculated aboveminAnd maximum value BpwmaxAnd recorded in the repeat purchase cycle table. Except BpwminAnd BpwmaxBesides, the repeated purchase cycle table may further include: repeat purchase cycle number CidCommodity type mark KidRepeated purchase week of the commodityPeriod category flags Bp and BpwminAnd BpwmaxThe unit of (c).

For example, to exclude the effects of the e-commerce promotional program, the resulting purchase data for the e-commerce promotional program may be removed from the user historical purchase data. Specifically, for the repeated purchase due to the e-commerce sales promotion activity, the purchased goods are counted in the last repeated purchase, and the number of the subsequent repeated purchases is sequentially reduced by 1. For example, if a user purchases a certain product 4 times, and if the 3 rd purchase of the certain product occurs due to an e-commerce sales promotion event, the 3 rd purchased product is counted in the 2 nd purchased product and the original 4 th purchase is counted as the 3 rd purchase when calculating the repeated purchase cycle of the certain product.
In operation S430, a repeat purchase time range of each item is estimated according to at least one repeat purchase period of each item.
According to an embodiment of the present disclosure, operation S430 may include, for example, calculating a latest repeat purchase cycle time and an earliest repeat purchase cycle time according to the following formulas:

is marked as K for commodity kindidThe earliest repeat purchase cycle time of the goods.
That is, the repeat purchase time range of the product is
Figure BDA0002252588430000114
Then, operation S230 is performed to determine that the product whose repeat purchase time range does not include the current time in the repeat purchase product set is the product to be excluded.
Specifically, the current time T is acquirednow. For each commodity, T is judgednowWhether or not in the repeat purchase time range of the goods

If in TnowIs out of position
Figure BDA0002252588430000116
And if so, the commodity is the commodity to be eliminated.
According to an embodiment of the present disclosure, a buyback status PBp may be set, setting the buyback status of such merchandise to be in a buyback cycle if the current time is within the repeat purchase time range. If the time is less than the earliest repeated purchasing period, the system is set to be in a consumption period. If the time is longer than the latest repeated purchasing cycle time, the state is set to be in a failure state. PBp may be expressed as:
Figure BDA0002252588430000117
wherein PBp ═ 0 indicates a buyback cycle, PBp ═ 1 indicates a consumption cycle, and PBp ═ 2 indicates a failure state.
Next, operation S240 may be performed to obtain a preferred goods set of the first user.
FIG. 5 schematically illustrates an example flow chart for obtaining a preferred merchandise set for a first user according to an embodiment of this disclosure.
As shown in fig. 5, operation S240 may include, for example, the following operations S510 to S540.
In operation S510, a similarity between a first user and a plurality of second users is determined.
In operation S520, a second user, whose similarity to the first user is greater than a similarity threshold, is determined from among the plurality of second users as a third user.
In operation S530, preference goods of all users are acquired.
In operation S540, a preferred goods set is determined according to goods preferred by the first user and preferred goods of the third user.
According to the embodiment of the disclosure, the similarity refers to the similarity between the first user and the second user for the commodity preference, and the similarity can be calculated by a Pearson correlation coefficient. Specifically, the scores of the first user and the second user for the commodity are firstly acquired. The score is used for reflecting the preference degree of the user for the commodity, and the higher the score is, the higher the preference degree of the user for the commodity is. In this embodiment, the score is given in an exemplary value range of 1 to 5.
Then, the similarity between the first user and each second user is calculated respectively. Let IcnRepresenting the set of commodities scored by the first user c and the second user n at the same time, the similarity between the first user c and the second user n may be calculated according to the following formula:
where sim (c, n) is the similarity between the first user c and the second user n, and r is IcnNumber of commodities in (1), RciFor the first user pair IcnThe score of the ith good in the second item,for the first user c to IcnAverage score of all goods in (1), RniFor the second user pair IcnThe score of the ith good in the second item,for a second user n to IcnAverage scores of all items in (a).
And then selecting the first K second users from large to small according to the obtained similarity, wherein the first K second users are the third users. Respectively calculating the first user c pair IcnA composite score for each of the items in (a). Specifically, K third users are taken as the nearest neighbor user set N of the first user ccCalculating the first user c pair I according to the following formulacnComposite score P of ith commodityci。

Alternatively, the set of preferred items I 'may be supplemented with items of a type that are not included in the set of preferred items I', but that are purchased by the user.
Next, in operation S250, a set of items to be recommended is determined according to the set of preferred items and the items to be excluded. Specifically, the commodities in the consumption cycle and the failure state can be excluded according to the buyback state of each commodity in the preference commodity set, and the remaining commodities are combined into the to-be-recommended commodity set.
Further, the top N (N is a positive integer and is less than or equal to the total number of the types of goods in the to-be-recommended set) types of goods in the to-be-recommended goods set may be selected to form a recommended item set, and goods are recommended to the user according to the recommended item set.
According to the embodiment of the disclosure, the commodities, the time range of which does not include the current time, of the repeatedly purchased commodity set are determined to be the commodities needing to be removed, and then the commodity set to be recommended is determined according to the preferred commodity set and the commodities needing to be removed, so that the commodities needing to be purchased can be recommended to the user more accurately, and the user experience can be improved.
