VoiceXML (Voice extensible Markup language)은 음성 대화를 웹의 마크업 언어로 기술할 수 있는 차세대 대화형 음성 서비스를 위한 표준이다. 현재 발표된 VoiceXML 1.0 사양은 음성대화의 기술에 초점을 두고 있으며, 음성 서비스의 시작 시점에 관해서는 언급이 없다. 본 논문에서는 사용자에 의해 시작하는 주문형 (on-demand) 음성 서비스 (inbound call) 뿐만 아니라, 최근에 고객관계관리 (CRM: Customer Relationship Management) 등에서 요구되는 시스템에 의한 푸쉬형 음성 서비스 (outbound call)가 가능한 VoiceXML 플랫폼을 설계하고 구현하였다. 또한, 본 논문에서는 W3C (World Wide Web Consortium)의 호 제어 요구사항 (Call Control Requirements)을 바탕으로 음성 대화 중에 팩스 송수신이 가능하도록 VoiceXML 문서형 정의 (UTD: Document Type Definition)를 확장하였다.

As computer-related technologies have been developed, legacy design systems have not been appropriate for new computing environment. Therefore, it is necessary that most of them are either modified or newly developed. However, this requires quite much amount of cost and time. This paper presents a method of extending legacy design system without modification using XML and XSLT. In order to apply the developed method, a good example of legacy design systems, AGMA gear rating system has been extended so as to be suitable for the distributed computing environment. An XML document for AGMA gear rating process is defined. It is transformed to the form of the input document of AGMA gear rating system by XSLT processor according to the transformation rules defined in the AGMA gear rating XSLT document. After that, AGMA gear rating system reads this input document and generates an output document in the server. These operations are automatically executed by the external legacy system controller without user interactions. Using these operations, AGMA gear rating web service has been developed based on SOAP and WSDL to provide the functions of legacy AGMA gear rating system through the distributed network. Any system or user can implement AGMA gear rating process independently to the platform type, without making it for oneself, by simply referring the AGMA gear rating web service via Internet.

A collaboration supporting system, which enables multi-user collaboration and communication in Internet environment, is being a new indispensable tool to compete and collaborate with business peers. A collaboration supporting system in distributed environment requires scalable and open system architecture to rapidly deploy a new technology and trends. In this paper, we propose such a collaboration supporting system where communication API is using XML(Extended Markup Language)-based SOAP(Simple Object Access Protocol)protocols, which Is independent on programming language and platform. In our system, server components are developed with EJB(Enterprise Java Beans). System analysis, design, and development are based on UML(Unified Modeling Language).

XML is a standard markup language for exchange and storage of formed or well-formed information in World Wide Web. Because the source data of XML message for exchange of information in World Wide Web is stored in legacy database, it is necessary for the easy connection between XML application and database system. In Oracle8i, 9i, Informix and SQL2000, DBMS vendors make upgrade to DBMS for using XML. This method of upgrade between XML application and database system is Platform-dependent and DBMS-dependent. Also It is necessary for the method of the platform- and DBMS-independent connection between XML application and database system. The methods for the connection between XML DTD and RDB schema are studied for the easy connection between XML application and database system. But the study for the easy connection between XML DTD and ORDB schema is a little. For multimedia application, we use the extended DBMS from RDBMS. It is necessary for the study to the transformation from XML DTD to ORDB schema. In this paper, for easier connection between XML application and database system, we propose the method of the transformation from XML DTD to ORDB schema using Object Model.

As computer-related technologies have been developed, legacy design systems have not been appropriate far new computing environment. It is necessary that most of them are either modified or newly developed. However, these activities require quite much amount of cost and time. This paper presents a method of extending legacy design systems to the internet without any modification using XML and XSLT. We have been extended legacy systems in the two viewpoints. First, an XML document has been defined to present the input information of a legacy system which is executed on the consol environment - MS DOS, for example. Also, an XSLT document has been generated to transform an XML document to the input document of the legacy system An XML document is transformed to the input document by XSLT processor according to the transformation rules defined in the XSLT document. This technique to generate input documents is independent to the platform type and facilitates to link legacy systems to other systems. Second, a legacy system controller has been made to control a legacy system and developed a web service to extend it and its controller. The legacy system controller operates it automatically. The web service provides its functions to other systems via internet. We have applied the developed methodologies to the legacy gear design system 조ich calculates AGMA gear rating md made AGMA gem rating web service.

이 논문에서 설계한 웹 기반 교육용 동적적응 하이퍼미디어 시스템에서는 영역 모델과 사용자 모델을 구조화하기 위해 XML을 기반으로 하는 마크업 언어를 정의한다. 이러한 마크업 언어는 웹 기반 교육용 적용형 하이퍼마디어 분야에서 자료를 구조화하기 위한 간단한 방법론을 가지고 쉽게 확장될 수 있고 저작될 수 있다. 또한 사용자의 브라우징 행위에 따라 자동적으로 하이퍼텍스트 네트워크를 재구성하는 학습 규칙을 제안하였다. 사용자 각각의 동적 이해 과정을 통해 하이퍼미디어 콘텐츠를 프리젠테이션 할 수 있는 기능을 포함하고 있다. 사용자 프로필은 사용자 모델 안에 포함되어 있고, 하이퍼미디어 콘텐츠인 영역 지식은 개념 기반의 영역 모델 형태로 설계되었으며, 제안된 학습 규칙에 따라 동적으로 재구조화가 이루어진다.

The distinguished prosperity of information technologies from great progress of e-business during the last decade has unavoidably made software development for active data mining to discovery hidden predictive information regarding business trends and behavior from vary large databases. Therefore this paper develops an active mining object(ADMO) component, which provides real-time predictive information from web databases. The ADMO component is to extended ADO(ActiveX Data Object) component to active data mining component based on COM(Component Object Model) for application program interface(API). ADMO component development made use of window script component(WSC) based on XML(eXtensible Markup Language). For the purpose of investigating the application environments and the practical schemes of the ADMO component, experiments for diverse practical applications were performed in this paper. As a result, ADMO component confirmed that it could effectively extract the analytic information of classification and aggregation from vary large databases for Web services.

현재의 전자문서처리 환경은 WYSIWYG 방식이다. 이를 위해 문서를 논리적인 구조와 물리적인 구조로 구조화하였고 이러한 구조를 마크업언어로 표현하고 있다. 특히 인터넷상의 전자문서 작성 및 교환을 위한 마크업언어로 XML이 발표되어 전자문서의 표현과 같은 전통적인 사용에서부터 검색을 위한 데이터베이스화에 이르기까지 전자문서의 활용 영역이 다양해지고 있다. 그러나 출력 품질면에서 워드프로세서나 전자출판에 의한 전자문서와 XML 문서의 출력 품질은 매우 큰 차이가 있다. 이는 비록 XML 문서가 스타일 정보를 포함하고 있긴 하지만 화면 출력과 인쇄 매체로의 출력 모두 고품질의 출력을 위한 적용이 부족했기 때문이다. 이러한 문제 해결을 위해 W3C에서는 고품질의 XML 출력 문서를 얻을 수 있도록 XSL-FO(XSL-Formatting Object)를 개발하였다. 한편 고품질의 전자출판물을 얻기 위해 폐이지 기술 언어(PDL)가 필요하고, 이의 업계표준인 Postscript가 이미 널리 사용되고 있다. 따라서 본 논문에서는 XML-FO를 PostScript에 적용함으로써 고품질의 XML 출력문서를 얻기 위한 변환기를 설계하였다.

A project planning is one of the most important processes that determines success and failure of the project. A pre-project planning is also essential job for information system implementations at the early stage of project planning, especially for management information system like ERP. However, pre-project planning is very difficult, because lots of factors and their relationships should be considered. Pre-project planning of ERP implementation has been done by project manager's own knowledge and experiences. In this article, we propose a system that help project manager to make a pre-project plan of ERP project with case-based reasoning(CBR) framework. The proposed CBR system saves previous cases of ERP pre-project planning in the case base. Then, the system finds the most similar case with the current pre-project planning problem. Project manager can make a pre-project plan by adjusting the most similar case. From the interview with project managers, we collect some field cases of ERP implementation. We organized these cases by using XML(Extensible Markup Language), which is good for representing hierarchical information. XML gives us some flexibilities to correct and maintain cases. We make a prototype system, PPSS(Project Planning Support System) that help project manager to make a pre-project plan of ERP implementations. The object of the system is to support project manager to make a pre-project plan of ERP. We hope the result of the study can be applied to other information systems. Our research would be extended to cover other stages of project planning.
