These servers 41 to 44 are nodes on the network system and are usually distributed to a plurality of computer groups 51. Of course, it is also possible to assign to single computer hardware. Large and high performance (and expensive) given the reliability of the system
Rather than configuring these nodes with a small number of computers, it is better to distribute the nodes over a number of cheaper computers, even if the individual capabilities are slightly lower, in order to reduce downtime and increase reliability. desirable.
At the hardware level, the computer hardware group 51 is connected to the Internet or another network system via a network device 52.

Here, the configuration of the agent server 42 will be described in more detail with reference to FIG.
The agent server 42 is a node on a computer, and has five servers: an agent event server 45, an agent messaging server 46, an agent monitoring server 47, an agent knowledge server 48, and an agent name server 49. The server 42 is a center in which these five servers function in cooperation.

The agent event server 45 has a function of managing and operating events occurring between the agent 31 and the system to which the agent 31 relates.
That is, the other four servers can synchronize with each other by the event management function centering on the agent event server 45, thereby enabling collaboration between the agents 31 in the net market system. The agent event server 45 is, for example, iSph
It can be configured by MetaApp server (trademark) manufactured by ere, and is the core of managing the synchronization of the other four servers by the Event-Driven method.

Agent messaging server 46
Supports message communication between agents 31 executed within the net market and with other net markets. Agent messaging server 46
Is characterized by loose coupling by message exchange, message delivery, provision of writing boards, agent 31
By providing a chat function between users and between users, it is used for communication between agents 31, systems, and humans (users), transmission of requests, and reply of results. The agent messaging server 46 not only supports communication within one net market, but also exchanges messages with other systems, other net markets, their users, etc. via a network through a firewall. The exchange makes it possible to synchronize and exchange information. The agent messaging server 46 is, for example, a Kizna manufactured by Kizna.
(Trademark) server.

The agent monitoring server 47
It records transactions between agents 31 and manages basic data for providing basic services such as billing information and security. The agent monitoring server 47 realizes monitoring of the activity of the agent 31 by using a function of a firewall such as packet filtering and content check.

The agent knowledge server 48 has a function of dynamically managing agent knowledge that can be used by each agent 31. The agent knowledge server 48 allows the agent 31 to dynamically incorporate available knowledge and store learned knowledge.

The agent name server 49 is provided for each agent 31 used in the net market system.
Manage definitions and states. Agent name server 4
Reference numeral 9 denotes a place where the definition of the agent 31 itself is determined and the dynamic state (state) of the agent 31 is stored in a time series. As a result, it is possible to use the past history and the record of generation together, and the server becomes a necessary server at the time of integration between markets and recovery from errors.

The agent knowledge server 48 and the agent name server 49 can be realized by a usual relational database or object database.

As described above, each of the centers 11 to 16
It is a virtual function executing means constituted by software, and each function is actually executed by receiving a service from each of the servers 41 to 44. Taking the communication center 11 as an example, communication equipment (not shown)
Application software for executing connection processing and data format exchange from the server is provided from the application server 44, and an agent (not shown) provided with the application software and knowledge for the communication center 11 dispatched from the agent server 42. ) Cooperate to execute a connection process or an authentication process based on data provided from the data server 43 or accumulate the result in the data server 43. In the processing performed by the communication center 11, the data to be temporarily stored is stored in the cache server 41.
And provided from the cache server 41 as needed. Similarly, the processing in the other centers 12 to 16
The respective functions are executed in response to the provision of services from the servers 41 to 44.

Next, FIG. 1, FIG. 3 and FIG. 4 show the flow when a user collects information using the net market system 1 according to the present embodiment and when a bid for public works is made. It will be described using FIG.

FIGS. 3 and 4 are diagrams schematically showing a case where the user collects information using the present net market system 1. FIG. First, as shown in FIG. 1, the user accesses the communication center 11 using the communication device 30 owned by the user. The communication center 11 executes a login process and an authentication procedure for connection with a user. These transaction data are sent to the transaction monitoring center 12. The user who has completed the connection sends a message about the information to be collected. It is the agent 31 that receives this message and executes the processing. Since the agent 31 has accumulated knowledge for analyzing the message and determining how to execute the process, the user's message is typically used to search for a search item, for example, when searching a traditional database. There is no need to tell. The processing of the agent 31 in response to the information collection request may be, for example, the case shown in FIG. 3 or the case shown in FIG.

The agent 31 analyzes which information collection method matches the purpose of the user. For example,
"The cosmetics brand candidates to be launched in the spring campaign,
Soft sound, flower image, women in their twenties. " In this case, the content of the message and the purpose of collecting the information are fairly clear,
You can relatively narrow down what information sources you access. Therefore, the agent 31 responds to the user's request by means of collecting information while moving each information source. This example will be described with reference to FIG. When the agent 31 determines the information collection destination, the agent 31 first moves to the Web search engine of the data center 13, collects information on recent trends of young women using keywords, and carries the information with the next database A (for example, Access the database about flowers) and pick up the names of spring flowers. The agent 31 adds the information and accesses the next database B (for example, linguistics, acoustics). Then, analyze the soft sound. Further, the user accesses the database C (registered trademark database) to drop the registered brand names or naming similar thereto from the information collected so far. For example, if the databases A, B, and C are legacy systems, the data is used via the legacy center 15. In this way, the agent 31 walks over the target information source before returning to the exchange center 16, analyzes the collected information, narrows down the brand name candidates, and sends a report to the user from the exchange center 16 to the communication center. 11 to the user.
Of course, the user ends the transmission after transmitting the information collection request message to the communication center 11, and
During this time, the agent 31 collects information, so that the user may access the communication center 11 again later to see the result. The transactions for the series of information collection processing are sent to the transaction monitoring center 12, and the transaction monitoring center 12 performs a charging process.

Next, for an example where the user's request for information collection is wider and it is difficult to narrow down the information source targets, the method shown in FIG. 4 can be considered. For example,
This is the case when the message "Consumption trends in the past six months" is given. When the user's message is transmitted to the exchange center 16 via the communication center 11, the agent 31a as a manager receives and analyzes the message. As a result, the processing for the user's request is performed by a plurality of agents 31b.
To 31e. And agent 31
b to 31e are dispatched to respective information sources. One agent is required to collect information from the legacy system 25 on the divided theme, and another agent is required to collect information from several Web sites. When the agents 31b to 31e dispatched in this way collect information and return to the exchange center 16, they write the results in, for example, a common memory area of the exchange center 16. All dispatched agents 3
When 1b-31e writes the result in the common memory area, the agent 31a as a manager analyzes the collected result, summarizes the report while comparing it with the user's message, and sends the report to the user. The billing process and the like are the same as those described with reference to FIG.

Next, a description will be given of a case where a bid for public works is made using the present net market system 1 with reference to FIG. 5 (note that connection processing, charging processing, etc. are described in FIG. 3). Since it is the same as the example described above, it is omitted here). FIG. 5 shows bid candidates A to D who want to receive an order for public works using the net market system 1.
With a company, soliciting contractors for ordering public works E ~
It is the figure which showed typically the relationship with H group. Each of the companies A to D transmits their desired case / condition as a bid request message via the communication center 11 of the net market system 1. Upon receiving the messages of the companies A to D, the agent 31A
31D are assigned to make a bid for public works that match the desired project / condition and mediate. On the other hand, the groups E to H transmit the specifications, conditions, and the like regarding the public works for ordering as messages via the communication center 11 of the net market system 1. Upon receiving the messages of the groups E to H, the agent 31
E to 31H write, for example, their specifications, conditions, bid deadlines, and the like in a common memory on the exchange center 16. This common memory is, for example, the exchange center 1
6 (see FIG. 1), and is controlled by an agent 31L that hosts these bids. Agent 31
L sequentially examines the public works projects written in the common memory against the user's request, and picks up bid candidates and reports them to the users 31A-31.
Instruct D. Upon receiving a bid decision from the user,
The agents 31A to 31D write the presentation of the bid conditions in the common memory. On the other hand, the agent 31L instructs the agents 31E to 31H to compare and examine the conditions of the bidders after the expiration of the bid deadline, and to report the most suitable bidder to the requesting organizations E to H.

As described above, when the present net market system 1 is used, the agent group mediates the message processing, so that it is possible to easily match the respective requirements between a large number of applicants and a large number of open recruiters. Can be.
In other words, both the applicant and the recruiter can select the most appropriate partner from among a large number of options.
This is not limited to bidding. It can be applied to matching of purchase conditions between many sellers and many buyers, such as auction and procurement of goods or reservation of passports and lodging facilities, and recruitment of joint business partners. Even now, individual market transactions such as auctions, procurement of goods, and reservations are provided on websites on the Internet. However, there has not yet been provided a system capable of achieving an integrated, more flexible and optimal problem solving for these services, such as the net market system according to the present invention.

The agent does not compare the conditions written asynchronously to the common memory as in the above example, but negotiates directly (or negotiates via the mediation agent) between the buyer's agent and the seller's agent. It is also possible to use a method in which negotiations are established if both conditions are met.

Further, if an intermediary agent having a credit / investigation capability and an agent intermediating a bank settlement business appear in the net market system, all of the operations from the start of negotiations or bidding to negotiations, acceptance of orders, and completion of settlement are performed. Can be completed within the market system.

In the present net market system, any processing requested by the user can be performed by interposing an agent having knowledge of various business models. The use examples of the net market system described above are only a part, and the embodiment of the net market system according to the present invention is not limited to these. It should be noted that security, which is currently a major problem in transactions via the Internet, can be solved in the net market system according to the present invention by interposing an agent having a function of ensuring security. A security center may be provided as a center function.
