KR20070069436A - Web-service discovery system based on intelligent agent flatform and method thereof - Google Patents

Abstract

A system and a method for discovering a web service based on an intelligent agent platform are provided to enable a user to use the desired service by enabling an agent to provide discovery for a UDDI(Universal Description, Discovery, and Integration) registry and an execution result of an e-business web service. An input part inputs a keyword to a UDDI client agent(10-1) included in the agent platform. A requestor requests service search to a UDDI server from the UDDI client agent by using the keyword. A receiver enables the UDDI client agent to receive a WSDL(Web Service Description Language) result from the UDDI server as a search result. A display part displays a web service execution result by enabling the UDDI client agent to analyze a received WSDL list and generate lists as many as the search result. A tool enables a user to input a personal key value and the keyword by enabling the UDDI client agent to make an API(Application Program Interface) to access the e-business service into an agent.

The present invention relates to a service discovery method for an intelligent agent platform-based web services (Web-Services) in a distributed ubiquitous environment and a method of using a service for providing a business service.

Intelligent agents are first defined as independent software with knowledge and reasoning capabilities and the ability to perform specific tasks on behalf of users. In addition, the Multi Intelligent Agent Platform maximizes the efficiency in performing tasks by collaborating between agents using knowledge and reasoning ability between each agent performing a task. It provides the basis for activity, and is responsible for the languages used by agents, the communication methods, and management between agents. In addition, by providing an interface accessible to the agent as a Web service, it enables the discovery and use of the service in the E-business service.

The characteristics of web services are not only fragmentary application features, but also communication between not only users but also mechanical applications, search through database, and binding of each service.

Elements of a web service include a simple object access protocol (SOAP), a web services description language (WSDL), and a universal description discovery and integration (UDDI). Briefly, their function is introduced. SOAP is a standard for the XML protocol that defines the message format used in the request and response of Web services. WSDL is used to describe SOAP messages, protocols, and internet location information of web services used to access web services. UDDI is a standard developed to support registry functions for web services. Provide a mechanism for discovery. The UDDI registry supports the registration and discovery of information about business objects and the web services provided by the business objects. The UDDI registry provides the registration, deletion, and retrieval of web services related to business data through a programming interface. However, the current web service structure does not actually provide enough functions required for E-business applications.

However, in the technique disclosed in the above-mentioned publication 10-0512015, only the message exchange method from the agent to the web service is considered, and in the technique disclosed in the above publication 10-0510040, the UDDI server processes the WSDL file. Only web service utilization methods that lack user-oriented business service processing are presented. For example, if a request is made to an UDDI server for a service from an agent, a message about a response may be received, but a method of using the agent is not considered at all. In other words, only one-way access is considered. In the present invention, we propose a discovery method for a web service using a FIPA intelligent agent and a practical use method for an e-business service. To solve the above problems, to provide an integrated system utilizing the advantages of each other.

In order to achieve the above object, the FIPA-based intelligent agent-based web service discovery system according to the present invention displays a request for the service of the agent and a response to the service as a work item of the client agent again on a platform connected through a network.

Intelligent agent-based web services for achieving the above-mentioned objectives are largely presented. It can be divided into a client agent (10-1) that handles the data stored in the registry by accessing the UDDI server and a client agent (10-2) that processes the actual business data to the user only for the site that provides the current web service. have.

In order to communicate with UDDI server, the following steps are required.

Inputting a search word from a user side into the web service system;

Requesting a web service search for a search word input to the UDDI server by the intelligent agent;

Receiving a list of WSDLs transmitted from a UDDI server as a result of a search;

Analyzing, by the agent, the received WSDL list, generating a web service list as much as the search result, performing the web service, and receiving the result;

Using the agent to use the e-business service, you can access the data using the API provided by the site. For example, Google (www.google.com) and Amazon ( www.amazon.com ) provide services based on pre-approved private key values and search terms.

According to the present invention, the agent can provide the execution result for the discovery of the UDDI registry and the E-business web service so that the user can use the desired service. By integrating the intelligent agent's original role and the wide web service in the Internet area, it shares the advantages of each other and provides high reliability for the web service.
