It is becoming increasing1y the norm for project teams to be composed of individuals who are geographically distributed but connected by high speed network. In such environments a lot of work related documents are created, so there is real needs for the system that facilitate the effective sharing, maintaining. managing of them. This paper present the system that satisfy this needs, which is known as IDOMA(Intelligent Documents management system based on Multi Agent). IDOMA is the cooperative multi agent based documents management system which has not centralized database.

The EDI system supports the working environment which can exchange the standardized document through the each agreed communication method. Traditional EDI system is complicated to be implemented and needed high cost te using the system because of the specific VAN(Value Added Network). This Paper proposes the XML/EDI system using the web-based distributed object and proposed the component 'AnySchema', as it makes be able to use legacy Database for EDI user. This XML/EDI system exchanges the XML documents through the Internet, so proposed low cost to support the system. Also, by using the XML document, it doesn't need EDI specific software and easy to exchange data between different systems. This system is implemented by using Java, as platform-independent.

Systematic management of data related to business process, and information exchange within existing information systems or between different companies have recently become an important issue. This paper tries to solve such problems by using form based workflow system using XML(extensible Markup Language), a standard for digital document exchange. In this system, a new model that formalizes documents into XML form documents and manages them is developed. By defining and operating form documents by XML, information exchange within existing information systems such as ERP and SCM or between different companies, and interoperability between different WFMS can be easily achieved. In addition, by matching form, a formalized document, with existing database schema, WFMS can be directly applied to existing information system, thus enabling continuity of data management and business activity.

In this paper. we develop associate knowledge extraction method for finding and expanding user preference knowledge automatically from web document database. To reflect user interest or preferences, agent explores and extracts relevant information to central term involving the intent of users from the example documents. To do so, we apply association rule exploration data-mining method to the extraction of the relevant objects in the web documents. Also, to give the weighted-value to the extracted and relevant information, we present associate tag block-based weighting method. We applied to bioinformatics above associate knowledge extraction method to find related keywords.

XML DTD is defining expression of simple form for XML document, there is much difficulties to define structure of XML document. Solving XML DTD's problem, W3C was select XML schema by standard in 2001. This paper proposes a design to XML DBMS using Relational Database based on XML schema to be selected by standard from W3C to overcome XML DBMS's shortcoming using XML DTD.

The goal of this study is to generate a structured document which improves the performance of an information retrieval system by using thesaurus, information on relations between words (terms), and to study on the technique for searching this structured document. In order to accomplish this goal, we propose a DODI (Depth -Oriented Decomposition Index) technique for the structured document and an algorithm to search for related information efficient]y through this index technique that uses a thesaurus. We establish a storage system by which the structured document generated by this index technique is saved in a database through OpenXML and XML documents are generated through ForXML methods.

본 연구는 온톨로지, 자연어 처리, 메타데이터 등의 시맨틱 웹 기반 기술들을 이용하여 시맨틱 웹 응용을 위한 전체적인 기술 적용과 그의 활용에 목적을 두고 있다. 이를 위해 OWL을 기반으로 조직이나 기관의 지식 주제별 도메인 온톨로지와, 기존 워드넷(WordNet)이나 더브린 코어 메타데이터(Dublin Core Meta Data)와 조직에 정의된 데이터베이스의 스키마를 MDR로 구축하여 상호 연결하여 온톨로지가 갖는 지능적 추론과 규칙 서비스와 표준화된 메타데이터의 결합 방법을 제공한다. 이는 기존에 온톨로지와 메타데이터의 재활용과 연결(Alignment)에 있어 연구적으로 높은 가치가 있다. 그리고 조직의 사용자가 문서를 작성할 때 문서의 내용에 대해 자연어 처리 기술과 온톨로지의 기술을 이용해 적합한 용어나 메타데이터를 자동으로 제공하여 작성된 문서의 공유와 재사용성을 높이고, 작성된 문서를 XML 형식으로 구성되는 XML 기반 지능 문서 데이터베이스(XMB Based Intelligent Document Database)에 저장하여 유사한 문서를 작성하거나 사용할 필요가 있는 사용자에게 문서 등록과 검색 에이전트(Document Registry and Retrieval Agent)를 통해 이러한 제공하여 문서 지식의 사유화를 최소화 하고, 유사 문서의 재작성과 또는 특정 문서의 작성에 필요한 시간이나 경비를 줄이게 된다. 또한 웹상이나 PDA 같은 개인 휴대장치를 통해서도 서 등록과 검색 에이전트를 통해 문서를 검색하고 사용할 수 있게 한다면 언제 어디서나 해당 서비스를 활용하는 유비쿼터스와 시맨틱 웹의 실질적 응용을 거둘 수도 있으리라 사료된다.

EDI is being considered as a new way for exchange business data in the form of electronic document, aiming the paperless transaction in business-to-business commerce. However, only a few enterprises select and practically use EDI accepts the closed and complicated method based on exclusive protocol for electronic document exchange. There, second, is insufficient regulation and system that support it. Last, the cost for operating is too high. In this paper, Open EDI Document Information Management System (OEIMS) was designed for solving the problem that mentioned above. We represented exchange document in code from as XML DTD. OEIMS that makers feasible to transfer their document through the web with low cost and, manage and search the information more efficiently and effectively using object-oriented database. We suggest OEIMS that provide efficiency to reposit and manage a system by modulized design of structural feature from EDI unlike other systems.

XML is broadly using for data storing and processing. XML is specified its structural characteristic and user can query with XPath when information from data document is needed. XPath query can process when the tern and structure of document and query is matched with each other. However, nowadays there are lots of data documents which are made by using different terminology and structure therefore user can not know the exact idea of target data. In fact, there are many possibilities that target data document has information which user is find or a similar ones. Accordingly user query should be processed when their term usage or structural characteristic is slightly different with data document. In order to do that we suggest a XML document ranking method based on path similarity. The method can measure a semantic similarity between user query and data document using three steps which are position, node and relaxation factors.

While the SGML(standard generalized markup language) tend to be used in multimedia document management systems, still binary document images are widely used in servicing the information of printed documents at digital libraries. But the printed documents are scanned in 200 dpi resolution and the scanned binary document images are compressed by the ITU-T T.6 method, so they have difficulties in representing them in good quality and compressing them very efficiently. In this paper, by considering quality of the binary document images and expandability and effectiveness of database of them, we show that the suitable scanning resolution of them is 600 dpi and the best compression method is the JBIG. A staged service strategy of them is also suggested to solve the difficulty caused from long decompression time of the JBIG by analyzing characteristics of retrieving the binary document images in monitor and printer. In experiments for several typical binary document images, high compression rate of the JBIG and effectiveness of the staged service strategy are verified.
