Business rule system and service method using ontology {SYSTEM AND METHOD FOR PROVIDING A SERVICE OF BUSINESS RULE USING ONTOLOGY}

The present invention relates to a business rule system and a service method thereof, and more particularly, by using an ontology search described for a business service processed in the form of rules. It relates to a business rule system and its service method.

The conventional business rule system is a rule server that executes a business service that receives rule data of business knowledge of a DB server and processes it in the form of a rule by request of a plurality of client computers, and delivers the execution result from the client computer. It is composed.

Since these business rule systems use rules, which are the rule data of knowledge built in the DB server, they are mainly defined by the system user or used only in the internal network and are not extended to the external network.

Therefore, the conventional business rule system is required to build a separate system for interworking between systems in order to provide business services in conjunction with an external network.

An object of the present invention is to search the ontology data of each system by adding a DB server for storing and managing the ontology data described for each business service use in the system of geographically dispersed network to solve the above problems of the prior art. It is to provide a business rule system and its service method using an ontology that can efficiently use business services by extending from an internal company network to an external network.

In order to achieve the above object, the present invention provides a system for providing a business service processed in the form of a rule, requesting an ontology search for a business service, receiving the searched ontology, analyzing the request, and requesting the processing of the business service. Stores and manages a number of client computers that receive the results of executing business services, and business knowledge data represented by the ontology data and rules described for the business services, and retrieves the ontology data retrieved when an ontology search is requested from the client computers. Processes a number of DB servers provided to client computers and business services expressed in the form of rules requested by client computers, and receives business knowledge data from DB servers before processing business services. It includes a rule server having a rule engine that delivers execution results to client computers.

In order to achieve the above object, the present invention provides a method for providing a business service processed in the form of a rule, the method comprising: retrieving whether ontology data described for a business service exists from a plurality of DB servers at the request of a client computer; When the ontology is retrieved from the DB server, the client computer receives the ontology data and analyzes it to acquire business service use, the client computer requests the rule server to process the business service, and the rule engine of the rule server. Receiving business knowledge data from a DB server and processing a business service expressed in the form of a rule requested by the client computer, and delivering a result of executing the business service to the client computer by a rule engine of a rule server It includes.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

First, when the terms used in the present invention are defined, a rule is one of the most widely known methods of expressing knowledge. The rule takes the form of an IF statement and a THEN statement, and if the condition of the IF statement is satisfied or occurred, the THEN statement is performed. Or logically true. A business service is composed of a number of rules for the processing of business units, and refers to the process of processing a set of rules and presenting the results of the processing. In addition, ontology can be defined as a work model of entities and interactions within a certain area of knowledge as a method of knowledge expression. In the present invention, ontology is used with business methods and other services for business services represented by rules. It refers to the matters related to the relationship.

1 is a schematic configuration diagram of a business rule system using the ontology of the present invention.

Referring to FIG. 1, a business rule system using the ontology of the present invention includes a plurality of client computers 10 (11, 12, 13, ...), a rule server 20, and a plurality of database servers (DB). 30).

Here, a plurality of client computers 10 (11, 12, 13…) are provided, request the ontology search described for any business service to the DB server 30, receive the searched ontology and analyze it, and the rule server Request the processing of the business service to receive the result of executing the business service.

The rule server 20 processes a business service expressed in the form of a rule requested by the client computer 10, and receives a rule data of business knowledge from the DB server 30 to execute a business service processed in the form of a provided rule. After that, the execution result of the business service is transmitted to the client computer 10.

The DB server 30 stores and manages ontology data described for business services and data of business knowledge expressed by rules, in which a plurality of servers are geographically distributed and distributed. When the client computer 10 requests an ontology search for a business service from the DB server 30, the ontology data is searched among the stored data and the retrieved ontology data is provided to the client computer 10.

In the business rule system of the present invention, the client computer 10, rule server 20 and DB server 30 are preferably configured in a network. At this time, the network is used such that not only intranet, but also interwork with external network system.

2 is a diagram showing the internal configuration of a business rule system using an ontology according to the present invention.

Referring to FIG. 2, in the business rule system according to the present invention, the rule server 20 is provided with a rule engine 22 to receive rule data of business knowledge from the DB server 30 to be processed in a rule form provided. After executing the business service serves to deliver the execution result of the business service to the client computer (10).

The DB server 30 also includes an ontology DB 32 in which ontology data described for the business service is stored, and a knowledge DB 34 in which business knowledge data expressed by rules is stored.

Therefore, the business rule system of the present invention has the ontology data described for the business service in its own ontology DB 32 when the client computer 10 requests the ontology search for the business service from the DB server 30 distributed on the network. If the ontology data is found, the requested ontology data is provided to the requesting client computer 10. When the client computer 10 requests the rule server 20 to process business services for the ontology data, the rule engine 22 is required to process the corresponding service in the knowledge DB 34 of the DB server 30. After receiving the business knowledge data expressed as a rule and executing the business service processed in the provided rule form, the execution result of the business service is transmitted to the corresponding client computer 10.

3 is a flowchart illustrating a service method of a business rule system using an ontology according to the present invention. 1 to 3, the business rule system according to the present invention provides a business service to each client computer in the following process.

First, a request is made for any client computer 10 to search for ontology data describing a business service desired to be provided to any DB server 30 geographically dispersed in a network for service use.

The arbitrary DB server 30 determines whether there is the ontology data in the ontology DB 32. (S12) As a result of the determination of S12, if the ontology data exists, the DB server 30 is the ontology retrieved from the DB 32 Deliver data to client computer 10. The client computer 10 analyzes the ontology data transmitted from the DB server 30 to acquire a business service using method (S14), and the client computer 10 determines whether an input parameter for using the business service exists. S16)

As a result of the determination in S16, if the input parameter exists, the client computer 10 inputs the input parameter and proceeds to the next step. (S18) Here, the input parameter refers to input data necessary for executing the business service.

The client computer 10 provides an input parameter to the rule engine 22 of the rule server 20 to request processing of the corresponding business service.

In response to the request, the rule engine 22 of the rule server 20 requests and receives knowledge data represented by a rule required for processing a corresponding business service from the knowledge DB 34 of the DB server 30, and receives the client data 10. Execution of the business service expressed in the form of a rule using the input parameter passed in the (S22).

The rule engine 22 of the rule server 20 determines whether there is an output parameter to transmit the processing result of the business service to the client computer 10 (S24), and if the output parameter exists, the business service using the output parameter. The result of the processing is transmitted to the client computer 10 (S26). Here, the output parameter refers to a parameter necessary for providing the execution result of the business service to the client computer 10.

If the client computer 10 does not need to transmit the result of the business service processing in step S24, that is, when there is no output parameter, the rule engine 22 of the rule server 20 sends a service processing completion message to the client computer. (10). (S28)

After performing steps S26 and S28, the client computer 10 moves to the next business service step after the current business service and performs the next business service step (S30).

If the ontology data describing the desired business service does not exist in the DB server 30, the client computer 10 searches whether the ontology of the service exists in another DB server geographically dispersed on the network. (S32) When the client computer 10 selects to search for the ontology data from another DB server, the process returns to step S10 to repeat the service process of the present invention. Otherwise, the service process of the present invention is terminated.

As described above, the present invention distributes DB servers that store and manage the ontology data described for the use of business services on a network, thereby extending the ontology data of each system to an external network outside the internal company network to search for the ontology data of each system. To the client computer.

On the other hand, the present invention is not limited to the above-described embodiment, various modifications are possible by those skilled in the art within the spirit and scope of the present invention described in the claims to be described later.
