It executes.Also, although logical order is shown in flow charts, and it in some cases, can be to be different from herein suitable
Sequence executes shown or described step.
Bayesian statistics infer be British scholar Bayes propose a kind of induction theory, after by some statistics
Person's development is a kind of Statistical Inference of system.The embodiment of the present invention is guidance with the basic thought that Bayesian statistics is inferred,
In the embodiment of the present invention, it is believed that any one new commodity defaults the average level that its quality is in entire store.In quotient
In the case that city commodity are enough, normal distribution is presented in marketing quality.That is a new commodity, quality is less likely significantly high
In the average level of existing commodity (referring to commodity), also it is less likely to be substantially less than average level.Therefore by existing commodity
Average quality shows the initial quality performance (i.e. initial evaluation) of (such as can be score value) as new commodity, then as commenting
The increase of valence client's number is gradually corrected the performance of its quality further according to subsequent evaluation (i.e. the practical manifestations of commodity), can effectively be kept away
The unilateral marking of the several clients for exempting from beginning is to injustice active influence caused by commodity.Based on above-mentioned theory premise, following evaluation is provided
Method.
Embodiment one
A kind of commodity evaluation method is present embodiments provided, as shown in Figure 1, this method includes S11-S12：
S11, using the predetermined average ratings with reference to commodity as the initial evaluation of the first commodity；
S12, after receiving newest evaluation to the first commodity, the first quotient is calculated on the basis of the initial evaluation of the first commodity
The current average ratings of product；When the evaluation of the first commodity received is more, the initial evaluation of the first commodity is current in the first commodity
Shared specific gravity is smaller in average ratings.
In the embodiment of the present invention, using the predetermined average ratings with reference to commodity as the initial evaluation of the first commodity,
As the scoring that commodity receive is more and more, the quality score proportion of itself is higher and higher, and true quality is able to completely
Show, to solve the problems, such as that new commodity is since the less caused scoring of client's number is one sided in online shopping mall.
In the present embodiment, the predetermined commodity that refer to include：Other all commodity in addition to the first commodity, or
Person and the first commodity belong to other of a sort all commodity.
In one alternate embodiment, described using the predetermined average ratings with reference to commodity as the first of the first commodity
Begin to evaluate, including：
Using the average ratings number of reference commodity as the initial evaluation number of the first commodity, and putting down reference commodity
Equal initial evaluation score of the evaluation score as the first commodity.
Refer to that averagely each how many people with reference to commodity gives a mark with reference to the average ratings number of commodity, with reference to being averaged for commodity
Evaluation score refers to the score of averagely each commodity.
It is preferred that with score come embodiment of evaluation, the evaluation score of commodity includes mass fraction and/or service score etc., can be with
Using the average value of all various scores as mean opinion score, only mass fraction can also be used as mean opinion score.Such as
Fruit Evaluation: Current is word evaluation, word evaluation can be quantified as evaluation score according to keyword and be calculated with facilitating.
In one alternate embodiment, described to calculate the current of the first commodity on the basis of the initial evaluation of the first commodity
Average ratings, including：
When calculating the current average ratings of the first commodity, the first commodity are calculated with the initial evaluation score of the first commodity
Current gross score calculates the current overall merit number of the first commodity with the initial evaluation number of the first commodity, with the first commodity
Current gross score and current overall merit number calculate the current average mark of the first commodity as current average ratings.For example, the
The current gross score of one commodity=first commodity initial evaluation score+newly-increased evaluation score, the current overall merit of the first commodity
Number=first commodity initial evaluation number+newly-increased evaluation number；The current average mark of first commodity=first commodity
The current overall merit number of current gross score/first commodity.It follows that as the actual evaluation of the first commodity is more and more,
The initial evaluation of first commodity shared weight (or specific gravity) in the first commodity Evaluation: Current is smaller and smaller.
In the embodiment of the present invention, the basic thought of Bayesian statistics deduction is used for reference, has been evaluated as with the commodity of shopping center
Application scenarios propose a kind of new scoring algorithm.Using the predetermined average ratings with reference to commodity as the first of the first commodity
Begin to evaluate；After receiving the newest evaluation to first commodity, institute is calculated on the basis of the initial evaluation of first commodity
State the current average ratings of the first commodity；When the evaluation of first commodity received is more, first commodity are initially commented
Valence specific gravity shared in the current average ratings of the first commodity is smaller, solves in online shopping mall new commodity due to client's number
The one sided problem of scoring caused by less makes the commodity of online shopping mall score more objective, improves the appraisement system matter in store
Amount promotes user experience.
Embodiment two
The present embodiment is the application example based on embodiment one, in this example using all commodity as referring to commodity into
Row explanation.
When a new commodity restocking, scoring change procedure is as follows：
(1) new commodity (the first commodity i.e. in embodiment one) restocking, client's number is 0 at this time；
(2) this new commodity is excluded in all commodity, calculates how many personal marking, i.e. initial evaluation of average each commodity
Number (alternatively referred to as priori scoring number), record result are u；
(3) this new commodity is excluded in all commodity, the score for calculating average each commodity is how many, i.e. initial evaluation point
Number (alternatively referred to as priori score value), record result are t；
(4) new commodity scoring initialization thinks to have had u people to make score, and the score that everyone gives is t；
(5) after new commodity receives first scoring x, the scoring of the commodity is modified to z1, and calculation formula is：Z1=(u*t
+x)/(u+1)
After new commodity receives second scoring y, the scoring of the commodity is modified to z2, and calculation formula is：Z2=(u*t+x+
y)/(u+2)
And so on.
According to algorithm above, the quality of new commodity is approximately equal to the average quality of all commodity in entire store, as commodity are received
The scoring arrived is more and more, and the quality score proportion of itself is higher and higher, and true quality is completely showed.
Embodiment three
A kind of commodity evaluation system is present embodiments provided, description is also applied for the present embodiment in above method embodiment
In, shown in Fig. 2, which includes initial evaluation confirmation unit 21 and Evaluation: Current computing unit 22, wherein：

Beginning, it is smaller to evaluate shared specific gravity in the current average ratings of the first commodity.
In the present embodiment, the predetermined commodity that refer to include：Other all commodity in addition to the first commodity, or
Person and the first commodity belong to other of a sort all commodity.
In one alternate embodiment, the Evaluation: Current computing unit 22 is using the average ratings of reference commodity as first
The initial evaluation of commodity, including：
Evaluation: Current computing unit 22 using the average ratings number of reference commodity as the initial evaluation number of the first commodity,
