Embodiment 1

[0037] Embodiment 1: as figure 1 As shown, an online service reputation measurement method based on inconsistent user evaluation criteria, first establishes the user’s preference relationship to the service from the user-service rating matrix, and expresses it as a preference relationship matrix; then calculates the consistency between user preference relationships Finally, find the users with the greatest preference relation consistency and score them as the service reputation.

[0038] The concrete steps of described method are as follows:

[0039] Step1. Establish the user's preference relationship for the service from the user-service scoring matrix, and express it as a preference relationship matrix

[0040] Step1.1, set the user set as U={u 1 , u 2 ,...,u m}, the service set is S={s 1 ,s 2 ,...,s n}, the user-service scoring matrix is ​​R=[r ij ] m×n , based on the rating matrix R to establish user u i ∈ U pairs of services s j ,s k The preference relation p ...

Embodiment 2

[0062] Embodiment 2: as figure 1 As shown, an online service reputation measurement method based on inconsistent user evaluation criteria, first establishes the user’s preference relationship to the service from the user-service rating matrix, and expresses it as a preference relationship matrix; then calculates the consistency between user preference relationships Finally, find the users with the greatest preference relation consistency and score them as the service reputation.

[0063] The concrete steps of described method are as follows:

[0064] Step1. Establish the user's preference relationship for the service from the user-service scoring matrix, and express it as a preference relationship matrix

[0065] Step1.1, set the user set as U={u 1 ,u 2 ,...,u m}, the service set is S={s 1 ,s 2 ,...,s n}, the user-service scoring matrix is ​​R=[r ij ] m×n , based on the rating matrix R to establish user u i ∈ U pairs of services s j ,s k The preference relation p o...

Embodiment 3

[0085] Embodiment 3: as figure 1 As shown, an online service reputation measurement method based on inconsistent user evaluation criteria, first establishes the user’s preference relationship to the service from the user-service rating matrix, and expresses it as a preference relationship matrix; then calculates the consistency between user preference relationships Finally, find the users with the greatest preference relation consistency and score them as the service reputation.

[0086] Also included is an assessment of the validity of the reputation measurement results:

[0087] By adding user u i to service s j Rated from r ij change to r ij ' to achieve the manipulation of the reputation, according to formula (1), the modification will lead to u i to s j The preference relationship with other services changes, which further makes u i The consistency of the preference relationship with other users changes so that the modification service s j The rating of s will not...

Abstract

The invention relates to an online service reputation measurement method based on inconsistent user evaluation criteria, belonging to the field of online reputation measurement and online services. The present invention first establishes the user's preference relationship to the service from the user-service scoring matrix, and expresses it as a preference relationship matrix; then calculates the consistency between the user preference relationships; finally finds the user with the largest preference relationship consistency and Scores serve as service reputation. The present invention embodies the inherent characteristics of inconsistent user evaluation criteria and the potential demand for reputation comparability management; the easy-to-understand user preference relationship consistency evaluation criteria provides a new modeling method for service reputation measurement when user evaluation criteria are inconsistent At the same time, by considering the relationship between users' ratings for different services, it provides a new idea for improving the anti-manipulation ability of reputation measurement methods.

Description

technical field [0001] The invention relates to an online service reputation measurement method based on inconsistent user evaluation criteria, belonging to the field of online reputation measurement and online services. Background technique [0002] The rapid development of the Internet and pervasive connection technology has enabled online service (referred to as service) models such as online shopping, online entertainment, online finance, and online software to be widely used in e-commerce, e-government, e-Learning, e-Science and other fields. However, users face many difficulties in choosing online services: ①The number of online services is huge, and users cannot have transaction experience with all services; ②Information asymmetry makes it difficult for users to have complete information about online services; Users usually cannot try online services; ④ service providers may provide users with untrue information. These problems make users need to use the reputation f...
