Embodiment Construction

[0068] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0069] refer to figure 1 , shows a flow chart of the steps of a dynamic adaptive service rating calculation method according to an embodiment of the present invention, including a dynamic window Q={r cached with historical ratings i-n ,...,r i-2 ,r i-1}, n is the current scoring number in the dynamic window Q, and the method may include the following steps:

[0070] Step S1: For a service S, after receiving the i-th rating r i , according to the current n historical scores r in the Q i-n ,...,r i-2 ,r i-1 , to estimate the current score f(i);

[0071] Step S2: compare the f(i) with the r i , to determine the rating r of the service S i whether it is fair;

[0072] Step S3: Adjust the range of the dynamic window Q accordi...

Abstract

The invention discloses a dynamic self-adaptive service evaluation calculation method and device. A dynamic window Q cached with historical scores is equal to [ri-n, ri-2, ri-1], wherein n is the number of current scores in the dynamic window Q. The method comprises the following steps: S1, for a service S, estimating a current score f (i) according to current n historical scores ri-n-ri-2, ri-1 in the Q when receiving an ith score ri; S2, comparing f (i) with ri, and judging whether the score ri of the service S is fair or not; S3, adjusting the range of the dynamic window Q according to thefairness of the score; and S4, calculating a service evaluation value Ri of the service S in the adjusted range of the dynamic window Q. According to the invention, dynamic calculation of the serviceevaluation value can be realized, and an accurate and reliable service evaluation value can be obtained, so that more effective and accurate feedback data can be provided for service providers or developers, and more reliable reference and basis can be provided for service selection of service users.

Description

technical field [0001] The invention relates to the technical field of service evaluation, in particular to a dynamic adaptive service evaluation calculation method and a dynamic adaptive service evaluation calculation device. Background technique [0002] In large-scale dynamic and open e-commerce, crowdsourcing and other service systems, it is difficult for service users to obtain clear characteristics of available services, and service evaluation models are introduced to describe service characteristics. At present, the service system evaluation models used by large-scale e-commerce platforms such as JD.com, Taobao, and Amazon, on the one hand, will be affected by unfair ratings, and on the other hand, the timeliness is insufficient, that is, there is a certain lag for dynamic changes in services . Contents of the invention [0003] The present invention provides a dynamic self-adaptive service evaluation calculation method and a dynamic self-adaptive service evaluatio...
