Abstract

Disclosed is a system which enforces that buyers of some service give fair evaluation to service providers from which the service was purchased. In e-marketplace or e-commerce in general, it is very common that buyers of a product evaluate the provider of the product in the form of a comment(in natural language) and/or a rating(in number such as 1 through 5). Such evaluation is used by other potential buyers when they make purchase decision from that provider. If a product is widely available in the market, it is expected that a buyer gives his evaluation to a provider fairly. When a buyer purchases a service or specialized capability(e.g. translation of documents) which can be provided by only some specific service providers, however, the buyer may not always rate the service provider fairly. Even if a buyer is satisfied with the service provided by a service provider, he may give a bad comment/rating to the service provider so that the value of the provider becomes low in the market, because the low value of the service provider allows the buyer to purchase the service from the same provider at lower cost next time. To prevent such unfair evaluation to a service provider, the following system was devised. A buyer rates a service provider by giving Yes/No answer indicating whether he wants

In e-marketplace or e-commerce in general, it is very common that buyers of a product evaluate the provider of the product in the form of a comment(in natural language) and/or a rating(in number such as 1 through 5). Such evaluation is used by other potential buyers when they make purchase decision from that provider. If a product is widely available in the market, it is expected that a buyer gives his evaluation to a provider fairly. When a buyer purchases a service or specialized capability(e.g. translation of documents) which can be provided by only some specific service providers, however, the buyer may not always rate the service provider fairly. Even if a buyer is satisfied with the service provided by a service provider, he may give a bad comment/rating to the service provider so that the value of the provider becomes low in the market, because the low value of the service provider allows the buyer to purchase the service from the same provider at lower cost next time.

To prevent such unfair evaluation to a service provider, the following system was devised.
