Description
Technical field
The present invention designs ecommerce correlative technology field, particularly a kind of e-commerce user purchasing power sorting technique and system.
Background technology
Along with the develop rapidly of electric firm industry, the personalized shopping need meeting user also becomes extremely urgent.Browsing user in the process of shopping recommends rational commodity greatly will promote Consumer's Experience to user.But the behind of the shopping commending system of property needs a large amount of user tag to support one by one.Wherein, the purchasing power label of user is essential.For the user that purchasing power is high, when selecting same class commodity, what often buy is the commodity that quality and price are all higher, and the user that such as purchasing power is high wants to buy a mobile phone, and he can buy the high-end handsets in apple or Samsung brand; And for the low user of purchasing power, such as he wants to buy an earphone, he can buy tens yuan or 20 yuan can meet the low-end product generally used.Thus, the definition for the purchasing power of a user is, user buy same class commodity time, the height of paying ability.
Purchasing power for electric business's field user is distinguished, and existing technology based on the method for user to high, medium and low commodity purchasing number of times accounting, is divided into high, normal, basic three class user mostly.Specific practice is: to each end level category, and the commodity that price segment is in the highest 20% are defined as high-end commodity, and the commodity that price segment is in minimum 20% are low side commodity, and the commodity of middle 60% are middle-end commodity.Then calculate the number of times accounting of the high-end commodity of purchase of each user, buy the number of times accounting of middle-end commodity, buy the number of times accounting of low side commodity.Finally see that user is maximum in the purchase number of times accounting of which grade commodity, then this user is divided in the middle of this purchase class user group.Finally obtain the high, medium and low Three Estate of purchasing power.
The shortcoming of prior art mainly contains four aspects:
1) when distinguishing price segment and being high, medium and low, the price segment of the commodity used, but in actual conditions, the purchase situation of the high price section of a lot of category is very sparse, even there is no sales volume, thus such clean cut rule be easy to cause result set to distribute unbalanced.
2) calculate user when each class buys commodity accounting, calculate and buy frequency accounting, do not add the price factor of commodity itself, cause accuracy rate to reduce.Such as, although a user has bought the commodity of the top grade of certain category a lot, but the price of this category is very low (diaper, household articles etc.) inherently, so he is bought in the expensive customer groups such as high-grade mobile phone, computer with other, nature can be unfair.
3) when obtaining the high, medium and low three kinds of commodity purchasing accountings of user, directly with accounting maximum determine final purchasing power grade, can accuracy rate be reduced.Such as, a user A is (0.8,0.2,0) in the accounting of purchase high-, middle-and low-end commodity respectively, and user B is (0.4,0.3,0.3) in the accounting of purchase high-, middle-and low-end commodity respectively.According to existing determination methods, user A and B is the user that purchasing power is high, and actual observation, we can be very easy to find, and user B similarly is not high-end user.This is because the purchase accounting of user also also should play a role the purchasing power that user is final in distribution, and simple maximum accounting rule judgment, not science.
4) grade of existing purchasing power is generally divided into high, normal, basic three ranks, classifies less, uses underaction.
Summary of the invention
Based on this, be necessary, for the inaccurate technical matters of the classification of prior art to user's purchasing power, to provide a kind of e-commerce user purchasing power sorting technique and system.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Be illustrated in figure 1 the workflow diagram of a kind of e-commerce user purchasing power of the present invention sorting technique, comprise:
Step S101, comprise: based on price and sales volume distribution, the commodity in same category are determined that class is high-grade commodity, the class of other commodity in same category is defined as non-top grade, be that the commodity of non-top grade are divided into x class from high to low from high to low successively according to price by class, wherein, x be default be more than or equal to 1 natural number;
Step S102, comprising: calculate the accounting that each user buys each class commodity, described accounting is carried out vectorization based on each user, and obtain the purchasing power vector of each user, described purchasing power vector is x+1 dimensional vector, and every one dimension is corresponding with a class;
Step S103, comprise: cluster computing is carried out to described purchasing power vector, obtain x+1 the point bunch about purchasing power vector, each point bunch corresponding respectively class, using the purchasing power class of purchasing power corresponding for user vector point bunch corresponding class as user.
The present invention proposes a kind of method more reasonably dividing user's purchasing power grade.The present invention be not simply only according to commodity price to distinguish commodity class, but carry out comprehensive assessment commodity class according to commodity price and corresponding Sales Volume of Commodity, because commodity class finally determines the purchasing power class of user, be exactly therefore the comprehensive assessment to user's purchasing power grade to the comprehensive assessment of commodity class.By the division methods automatically regulated based on price and sales volume distribution high-grade goods, the level evaluation of correspondingly user's purchasing power is made to also achieve automatic adjustment, make the classification of user's purchasing power more accurate, thus improve the experience of user in website widely.
Wherein in an embodiment, described step S101, specifically comprises: the class of the commodity of a% before price segment in same category is defined as top grade, and a adopts and confirms with the following method:
More than three or three spans are selected to be treat selective value between 0 ~ 100, maximum treats that selective value is as MAXIMUM SELECTION value, minimumly treat that selective value is minimum selective value, other treat that selective value is middle selective value, m is made to be the price statistics value of the front y% of price in same category, n is made to be the price statistics value having the front y% of price in the commodity of sales volume in same category in nearest preset time period, if m is greater than n and exceedes preset first threshold value, then a is selected to be MAXIMUM SELECTION value, if n is greater than m and exceedes default Second Threshold, then selection a is the minimum value in minimum selective value, other situations, selection a is one in middle selective value, wherein, y is less than MAXIMUM SELECTION value and is greater than minimum selective value.
First, to mark all commodity, because the purchasing power of user finally will be divided into X+1 grade by purchasing power model, preferably, X+1 is 5, then the purchasing power of user be divided into height, higher, in, in low, low five grades, so in the process marked commodity, all commodity also will be also designated as X class by us, are preferably top grade, higher gear, middle-grade, low and middle-grade, low-grade five class.Because the clean cut method mentioned in the introduction can make the high-grade goods of a lot of category very sparse.So divide high-grade goods, the present embodiment regulates division number percent automatically according to the price of each category commodity and sales volume distribution situation.For a category, such as three grades of categories, the commodity choosing a% before being in price segment are high-grade goods, and wherein, a is preferably three, can select 5,10 or 20, and namely a% can be 5%, 10 or 20%.The concrete value of a needs first to calculate two indices m, n, wherein m is the price statistics value that this category price is positioned at front y%, n is price statistics value (the not deduplication having the commodity price of sales volume to be positioned at front y% in this category nearly a period of time, if commodity are bought repeatedly, also count).Y is preferably 10%, the mxm. after the price statistics value of front y% is preferably and is removed by the commodity of front y% in surplus commodities.Like this, if m>>n, before this category price is described, 10% Sales Volume of Commodity is bad, and the threshold value of high-end commodity should improve, i.e. a=20%; If n>>m, before the price of this category is described, 10% Sales Volume of Commodity is fine, should get less, reduces threshold value, i.e. a=5%; Other situation a=10%.Just accomplish that the judgment threshold of high-end commodity can carry out self-regulation according to the actual conditions of selling thus.The value of m should between the centre of a value, but not necessarily intermediate value.Here value all can change.Concrete process flow diagram is as shown in Figure 2:
Step S201, calculates the price statistics value m that this category price is positioned at before 10 10%;
Step S202, calculates in this category nearly a period of time and has the commodity price of sales volume to be positioned at the price statistics value of front 10%;
Step S203, if m>>n, namely m is greater than n and exceedes first threshold, and first threshold can get larger scope, then an a%=20%, otherwise performs step S204;
Step S204, if n>>m, and n is greater than m and exceedes Second Threshold, and Second Threshold can get larger scope, then an a%=5%, otherwise a%=10.
For high-end commodity, supplementing of some systematicness can also be added, the commodity that such as luxurious category, high-end nonessential product (as smart machine etc.) or cargo price are very high.
The class of remaining commodity is non-high-end, be divided into X class (X be greater than 1 natural number), preferably, can be divided into higher, in, in low, low four class, wherein, low-grade goods can get the commodity of rear 20% of price segment, higher shelves, middle-grade, low and middle-grade be front 1/3 after removing top grade and low grade respectively, middle 1/3 and below 1/3.
Wherein in an embodiment, described step S102, specifically comprises:
For each user, calculate this user each class the amount of placing an order with dutiable value is taken the logarithm after product as the purchase volume of this user at this class, calculate the purchase volume summation of all class of this user, calculate each user accounts for the purchase volume summation of this user ratio in the purchase volume of each class buys each class commodity accounting as user;
For each user, the vector that the accounting each user being bought each class commodity is tieed up as an x+1, obtains the purchasing power vector of each user.
Calculate the accounting of each user at each class commodity purchasing, the vector of an X+1 dimension can be obtained, be preferably five dimensional vector (x
1, x
2, x
3, x
4, x
5), be called purchasing power vector.Wherein x
irepresent the accounting that this user is the commodity purchasing of i-th grade at class.At each class accounting x of calculating
itime, calculate the accounting buying commodity frequency j (i.e. the amount of placing an order) at each class, but calculate user each class buy commodity the frequency × ln (price) (namely the amount of placing an order and price take the logarithm after product) accounting.Such as certain user has bought two commodity A, B altogether in high-grade goods, the number of times bought respectively is k1, k2, and price is respectively p1, p2, then user buys as k1 × ln (p1)+k2 × ln (p2) at top grade, wherein, ln represents the logarithm to numerical value in bracket.Calculate this user after the purchase volume of each class according to this method, then the purchase volume obtaining each class accounts for the accounting of total purchase volume.Here the price adding commodity gets log as weight, thus solves second shortcoming of the prior art mentioned in background technology.Add the price factor of commodity itself, even if user has bought a lot of relatively high-grade commodity in low price category, also can be low because of price weight, adjusted.
As shown in Figure 3, wherein in an embodiment, described step S103, specifically comprises:
Step S301, comprising: from the purchasing power vector of all users, the purchasing power vector of a random selecting x+1 user is as the center, execution step S302;
