Hey Matthew, even two 5 star reviews don't have the same weight. Pretty much everything is connected to an algorithm on Amazon. For instance here is how "top reviews" are listed on Amazon.
(H+C1+log(min(Length,C2*5)) / log (C2)+ X/2 × Trust + X/2 × Recency)) / (T+C3))
H: the number of helpful votes a review received
T: the number of total votes a review received
X: log(C2*5) / log (C2)
Length: length of a review
Trust: If the review is verified purchase: 2 * (sigmoid(# of reviews written by a reviewer * 0.1) - 0.5)
otherwise: sigmoid(# of reviews written by a reviewer * 0.1) - 0.5
Recency: 2 * 1/(1+exp((time - submission_date) / (30 months)))
C1, C2, and C3: Constants set differently by marketplace. In the US, C1, C2, and C3 are 13.1056, 350, and 20.04, respectively.
就算给他了，他也算不出来。
这是公式 |
