Abstract:

We put forward a commodity screening method  on the basis of the theoretical method of extenics’ score theories, such as primitive theory, extension transformation, correlation of matterelement etc,  and take clothes as example to verify the validity of this method. In addition, we analyzed the correlation of matterelement and presented the method of commodity similarity based on the extenics. No doubt, it promotes the development of electronic commerce, what’s more, it opens up a new direction for the application of extenics.

Key words: primitive theory, correlation of matterelement, commodity screening method, commodity similarity
