Information searched in UDDI transfer web service user. Then web service user require interface to web service publisher. In this paper, we abbreviate procedure it. UDDI require WSDL document to web service publisher. For this reason, UDDI transfer XML form message to publisher. Message include user's location information and UDDI required document transfer from publisher to user. Message using SOAP protocol of XML format.

The Kalman Filter is one of the most common techniques of tracking mobile user. Web service is a promising method of reusing programs. Therefore, this paper presents our implementation of Kalman Filter web service. There are three ways of implementing a web service system. Ours is Kalman filter as RPC web service.

Web services are standardized software technologies that enable interoperability of operating systems and programming languages through networks and related standards. Web services are distributed computing services that provide and discover services making it possible to access various services. Since the search method of web service considers only the functional aspect, it has a limitation on user-oriented search when selecting a service. In order to solve these problems, this study proposes an automatic IoT information generation tool, and provides IoT extension information when searching a web service, thereby improving the problem so that a suitable service can be selected for a user. Automatic IoT extension information generation tool proposed in this study collects and stores various information generated in the process of sensing, networking, and information processing by collaborating autonomously in a distributed environment of user, object, and service. The proposed method supports the service search suitable for the user by providing the information generated by the user as extended information when searching the web service. The proposed method can be applied to the 4th industry sector to provide a customized service that meets various environment requirements.

The 'convergence service' in NGN implies the integration of services in NGN with a unified manner to access each service in order to interwork with each service. This Recommendation defines the convergence model for NGN based on Web Services and provides a detailed scenario of each convergence model in form of Web Services.

The rapid development of information and communication technologies has resulted in rapid increase in the qualitative and quantitative information that can be accessed by information technology. Furthermore an enormous amount of information is provided in various formats. However, there are a group of people who are not able to even approach to targeted information due to physical or environmental problems. Visually handicapped users constitute a class of these users. In this paper, a method of developing user interface for web-based education service is described for the visually handicapped users to access information more efficiently. First, this paper analyzed the problems of visually handicapped users to access information targeting representative domestic sites that supply education services. And based on the results of the above analyses, Nest, this paper explains the web-based education service interface implementation method according to types of the content to be delivered. Lastly, the validity of this method is provided by testing a web page based on the implementation method according to the types of content.

With the spread of Internet, e-business using Internet technology is being actively developed and operated. Currently, on behalf of the international e-business framework, International standard such as ebXML and Web Service is being advanced. We are able to publish and search business information through ebXML and Web Service and then actual trading between partners is accomplished. By the way, it is Registry that play an important part in e-business. Registry is an e-business infrastructure for enabling building, deploying, and the discovery of business Information. We can do e-business through Registries dynamically and share the resources. Representatives of Registry are ebXML and UDDI used as an international standard. We will meet with some problems when using Registries. ebXML Is focused on B2B collaborations and Web Service Is focused on application integrations. So we must use ebXML and Web Service characteristically, and sometimes use all at need. ebXML and Web Service contain business information by Registry specific way. So When using the services offered by ebXML and Web Service, we should access each Registry by using Registry specific tools. This thesis intended to integrate business information from ebXML Registry and UDDI Registry to accomplish e-business conveniently This thesis defined the common data model as well as integrated query language for integrated access to ebXML and Web Service along with design and implementation of the system.

To improve performance, most of Web Services produce and manage User Access Logs. Through the Access Logs, the record provides information about time when the most traffic happens and logs and which resource is mostly used. Then, the log can be used to analyze. However, in case of increasing high traffics of Web Services at the specific time, the performance of Web Service leads to deterioration because the number of processing User Access Logs is increasing rapidly. To solve this problem, we should improve the system performance, or tuning is needed, but it makes a problem cost a lot of money. Also, after it happens, it is not necessary to build such system by spending extra money. Therefore, this paper described the effective Web Service's performance as using improved User Access Log performance. Also, to process the newest data in bulk, this paper includes a method applying some parts of NoSQL using Redis.

Spatial information has recently been recognized as one of the major subjects of interest in information technology. With increasing variety and quantity of spatial data on the web, searching and maintaining these data are becoming a much focussed area of research. Interoperability is the key technology in solving the complexities of spatial data in web services. The problem of maintenance and searching of spatial data in an interoperable web service environment can be solved by establishing standardized metadata of spatial information. Then using the standardized metadata, catalog web services can be deployed for autonomous searching and binding of spatial data. This study investigates the international standard for spatial data metadata(ISO/TC211 19115) and deployed catalog web service based on this metadata. Various heterogeneous spatial data of Seoul Metropolitan region were then used for experimental implementation of catalog web service.

Recently, RFID(Radio Frequency IDentification) has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles : companies have their own operating systems. while RFID is developed regardless of each campany's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system Middle assures that companies adopting RFID system for their logistic service are given athptabwebty to any systems whatsoever, avaweable by way of defining logistic information, tag information and reader information. For this purse, we implement as the basic web service a middleware system that turns all data into XML(eXtensatle Markupmsngunfo) of SOAP(Simple Object Access Protocol), the standard data.
