Embodiment 1

[0050] Embodiment 1: An online product group evaluation method based on Copeland's social choice theory, first fills incomplete consumer-commodity rating matrix based on the similarity between consumer historical ratings; then establishes each The preference relationship of consumers for online commodities is summarized and expressed as a commodity-commodity preference comparison matrix; finally, Copeland’s social choice theory is used to compare the commodity preferences in the commodity-commodity preference comparison matrix one by one, and the statistical win is calculated according to the comparison results. The number of losses, build a win-lose matrix, and sort the difference between wins and losses to achieve online commodity group evaluation.

[0051] The specific steps are:

[0052] Step 1. Fill the incomplete consumer-commodity rating matrix based on the similarity between consumer historical ratings;

[0053] 1.1. Let the set of consumers be U={u 1 , u 2 ,...,u ...

Embodiment 2

[0075] Embodiment 2: as figure 1 As shown, an online commodity group evaluation method based on Copeland’s social choice theory, first fills the incomplete consumer-commodity rating matrix based on the similarity between consumers’ historical ratings; The user’s preference relationship for online commodities is summarized and expressed as a commodity-commodity preference comparison matrix; finally, Copeland’s social choice theory is used to compare the commodity preferences in the commodity-commodity preference comparison matrix one by one, and the winners and losers are counted according to the comparison results. times, construct a win-lose matrix, and sort the difference between wins and losses to realize group evaluation of online commodities.

[0076] 1. Check whether the consumer-product rating matrix is ​​complete. If it is not complete, you need to fill in the data set first. Suppose there is a consumer-commodity rating matrix S=[R a×b ] 6×5 , as shown in Table 5: t...

Abstract

The invention relates to a Copeland social selection theory-based online commodity group evaluation method, and belongs to the technical field of online commodities and social selection theories. The method comprises the steps of firstly performing filling on an incomplete consumer-commodity scoring matrix based on similarity between historical scores of consumers; secondly according to the scoring matrix filled to be complete, establishing a preference relationship of each consumer to online commodities, summarizing the preference relationships and performing expression as a commodity-commodity preference comparison matrix; and finally comparing commodity preferences in the commodity-commodity preference comparison matrix one by one by utilizing a Copeland social selection theory, performing accumulation according to a comparison result, performing statistics on win or lose times, constructing a win-lose matrix, and sorting win-lose difference values, thereby realizing online commodity group evaluation. According to the method, the control complexity is increased; the problem that bad merchants perform control on group evaluation of the online commodities is relieved; and the situation that autocratic consumers control evaluation results is effectively avoided, so that the evaluation results are fairer and more equitable.

Description

technical field [0001] The invention relates to an online commodity group evaluation method based on Copeland's social choice theory, and belongs to the technical field of online commodity and social choice theory. Background technique [0002] With the vigorous development of e-commerce and electronic services, online shopping has been widely used in people's daily life. However, due to the virtuality and anonymity of the Internet, consumers face many difficulties in choosing suitable products: First, consumers have no way of verifying the authenticity, reliability and quality of the products sold by the merchants before the transaction , can only compare the pros and cons of products by searching and viewing a large number of ratings and reviews of the same product; secondly, fewer ratings of the same product will also affect consumers’ purchase judgments; then, in the actual transaction process, there will be individual consumers Autocratic phenomenon, autocratic individ...
