Abstract: A mutual credit server apparatus sends credit information about a seller to an inquiring buyer on a computer. Stored is a direct confidence degree about a seller from the point of view of each of a plurality of buyers. The direct confidence degree is determined by each buyer based on direct trade history. Also stored is a buyer confidence degree about each of the plurality of buyers from the point of view of each buyer. The buyer confidence degree is determined by each buyer based upon trade information from the other buyers. When a confidence inquiry is made about a seller by a buyer, a processing section calculates a total confidence degree about the seller and calculates a buyer confidence degree about each of the other buyers, each calculation being made from the viewpoint of the inquiring buyer.

The conversation completion timing is detected in advance by detecting execution of a specific portion of the program on the operator terminal, and the number of calls to be automatically originated is determined on the basis of the number of operators, whose conversation completion timings are detected in advance.

Abstract: A message transmission and page processing scheme for a hypermedia document processing system, in which the source information which contains a source server identifier for identifying a source server in the system, a source page identifier for identifying a source page in the system, a request page identifier for identifying the request page in the system, and a request target server identifier for identifying a request target server in the system, is transmitted from a client device to a server device either directly or through a relay server device. A prescribed processing according to the source information is then carried out at the server device. In a case of using the relay server device, the relay server device can counts a number of source information, or separate the source information from a request message transmitted from the client device, or generate the source information from the page message from the server device and the request message from the client device.
