The present invention relates to a client product information evaluation system and evaluation method on a network. More specifically, the client product information evaluation system on a network for evaluating client product information stored in a server computer and using the evaluation result as product purchase information; It is about evaluation method.

Recently, thanks to the technological advances in computer and communication networks, the exchange of information and the collection of information are easily performed, which affects various fields of society. Electronic commerce based on the so-called Internet world wide web In response to the trend of widespread use of commerce), various trading methods are actively being promoted.

In response to these changes, companies have opened their own websites on the Internet to provide product information to client computers and operate shopping malls, which can deliver ordered products to clients. In the home shopping that purchases products at this shopping mall, the client computer is connected to the server computer of the website, and the desired information is easily operated by simply clicking the mouse with reference to the product information (product price, product specification, field of use, etc.) provided. By purchasing the product, the distribution stage of the product is reduced compared to the classic commerce of going directly to the market and purchasing the product, and it is possible to purchase the product at a simple and low cost.

Recently, when a customer who wants to purchase a product presents a purchase price, a commodity trading service company that runs a so-called 'reverse auction' that connects sellers who have responded to the price is running a website on the Internet. In addition, by combining the advantages of home shopping using shopping malls and additional discounts for mass purchases, a website that arranges a so-called 'joint purchase' is being operated.

In this way, in the cyber shopping space where products are traded on the Internet, general clients can use them, and additional members are given additional benefits to increase their utilization rate. In this case, the registered member purchases the product using his / her member ID and password and is rewarded according to the purchase result.

FIG. 1 shows a general usage environment of an electronic commerce, and a web site 30 of a service provider, which is connected to a plurality of client computers 10 to the Internet 20 and opened for commodity trading on the Internet 20, is shown in FIG. It is composed of The client computer 10 is a terminal connected to a personal computer (PC) or a local area network (LAN). The client computer 10 enters the domain of the website and connects to the server computer of the website 30 connected to the Internet 20. The server computer of the website 30 is open to the general client so that it can be used without limitation, or limited to the registered members who have made a predetermined subscription application. In general, a client may determine whether to purchase a product by looking at operator product information (including a video image) provided by an operator who operates a server computer of the website 30.

In addition to the operator product information, the server computer of the website 30 provides the product information written by the client. The client product information is mainly used for the purchase and use of the purchased product (feel like the actual use, ask the operator of the website). Want to answer questions about the product, etc.) is a relatively short paragraph.

This client product information is constructed as a database on the server computer of the website 30, and provided as a list on the screen so that the client can read by clicking with a mouse. This list will display the serial number, title, number of inquiry and creation date for a number of already stored client product information in one bundle. In addition, this list shows recently created client product information and is usually posted for a certain period of time. During the period in which the client product information is posted, the client accessing the server computer of the website 30 can read the client product information related to the use and purchase of the product in addition to the operator product information such as the product price and the product description.

However, in the prior art, since the client product information provided is mainly created based on the client's own experience, when the actual product is purchased, the client product information is not interested in the client product information and depends on the product information provided by the operator who operates the website server computer. . In this way, the product information provided by the operator is simple in consideration of processing speed and data capacity, for example, it provides only limited information such as price, product specification, field of use, and video image of the product, so it is insufficient to stimulate the purchase motivation of the client. .

Therefore, a client who purchases a product needs to obtain additional purchase information as the actual information related to the use and purchase of the product in addition to the product information provided.

In addition, it is necessary for the operator of the website to facilitate the purchase motivation of the client by providing the product purchase information to the client to assist the purchase decision of the product for the purpose of increasing the number of uses and the use of many clients.

The present invention has been made to solve the above problems, an object of the present invention is to evaluate the client product information stored in the server computer and evaluate the client product information system on the network to utilize the evaluation results as product purchase information and evaluation In providing a method.
