The importance of EDI has been so emphasized that we need exchange/maintain electronic documents effectively, and convert then to other formats. The traditional EDI, however, is facing on the limitation of growth because of it's high expense, and the closenees of sharing information. The EDls of next generation, like open EDI, object-oriented EDI, and Internet EDI, have appeared to solve these problems. Finally, XML/EDl, which is very effective to solve these kinds of problems, is now replacing the traditional EDI and the HTML in Internet and is influencing on e-Business. So, we are going to suggest a solution which uses XML/EDl as a substitute for the traditional one. First, we analyzed the problems of the traditional EDI system and organized the structure of XML/EDl system. Next, we have developed the prototype of Internet bookstore to show the effectiveness and strength of XML/EDl over the traditional EDI.

IPSEC (Internet Protocol Security) is a network layer security protocol that is designed to support secure TCP/IP environment over the Internet considering flexibility, scalability, and interoperability. IPSEC primarily supports security among hosts rather than users unlike the other security protocols. Recently, IPSEC is emphasized as one of the important security infrastructures in the NGI (Next Generation Internet). It also has suitable features to implement VPN (Virtual Private Network) efficiently and its application areas are expected to grow rapidly. In this paper, the basic concepts and related standard documents of IPSEC will be introduced.

인터넷 중심의 정보화 사회가 되면서 기존의 문서는 대부분 전자 문서로 대치되어 가고 있다. 전자 문서간의 호환과 표준화를 위하여 XML(eXtensible Markup Language)이 웹 문서의 표준으로 지정되었으나, 현재까지 사용되고 있는 문서들이 XML 형태의 문서가 아니므로 이를 수동으로 변환해야 하는 어려움이 있다. 본 논문에서는 규칙기반 분서 분류기(Rule-Based Document Classifier)를 설계하여 다양한 형태의 문서를 자동으로 분류하고 그룹화한다. 그룹화된 문서를 이용하여 자동으로 DTD(Document Type Definition)를 생성하고, 자동 생성된 DTD를 이용하여 XML 형태의 문서로 자동 변환할 수 있는 자동 XML 변환기를 제시한다. 이러한 방법은 문서들을 자동으로 분류하고, 문서의 행태에 변화가 있을 때에도 유사한 문서로 분류할수 있을 뿐만 아니라 문서를 재분류할 때 DTD의 중복 생성을 줄일 수 있는 등의 장점을 갖는다.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

Automatic document classification may differ significantly according to the characteristics of documents that are subject to classification, as well as classifier's performance. This research identifies e-mail document's characteristics to apply a three-step preprocessing algorithm that can minimize e-mail document's atypical characteristics. In the first 5go, uncertain based sampling algorithm that used Mean Absolute Deviation(MAD), is used to address the question of selection learning document for the rule generation at the time of classification. In the subsequent stage, Weighted vlaue assigning method by attribute is applied to increase the discriminating capability of the terms that appear on the title on the e-mail document characteristic level. in the third and last stage, accuracy level during classification by each category is increased by using Naive Bayesian Presumptive Algorithm's Dynamic Threshold. And, we implemented an E-Mail Recommendtion System using a three-step preprocessing algorithm the enable users for direct and optimal classification with the recommendation of the applicable category when a mail arrives.

차세대 웹 문서의 새로운 표준으로 자리 잡아 가고 있는 XML은 전자 상거래나 병원 관리 등과 같이 다양한 응용 분야에 적용되고 있다. 이러한 응용 분야는 XML 문서의 각 구성 요소 수준의 세밀한 액세스 제어를 요구한다. 따라서, 현재 XML 문서의 미세 접근 제어 기법에 대한 연구가 활발히 이루어지고 있다. 현재 제안된 XML 문서를 위한 미세 접근 제어 기법은 대부분 묵시적 권한 기법을 사용하여 상위 구성요소에 한번의 권한 부여로 하위노드에 권한을 부여하는 효과를 가지는 장점을 가지나, 각 구성 요소간의 권한을 체크하는 시간 오버헤드를 가지는 단점이 있다. 본 논문에서는 권한을 체크하는 시간을 감소시키기 위하여 XML 문서의 미세 접근 제어를 위한 명시적 권한 기법을 제안하고, 이를 이용하여 노드의 권한에 대한 모든 정보를 저장하고 있는 접근 권한 트리 모델을 제시하였다. 본 논문에서 제안한 접근 권한 트리 모델을 사용하면, 권한 정보를 저장하는 공간 오버헤드가 있지만, 권한 체크 시간을 감소시켜 사용자에게 보다 빠른 뷰를 제공할 수 있다.

EDI(Electronic Data Interchange) allows the exchange of business information and computer-processable data in a standard, structured format electronically between organizational entities. EDI handles the restructuring of a business document into the standard format so that it can be transmitted from one computer to another. This paper identifies features and technologies of web browsed electronic document exchange system as follows 1) the fundamental technologies that consists of the EDI technologies, the Internet/Web technologies, the security/authentication techniques, and the XML implementation technologies. 2) the functions that consists of the document standards, transfer technology of the document, encryption and authentication 3) the implemented Web-EDI systems that consists of document generation module, encryption and authentication module, transfer module, acknowledgement module, administration module. In this paper, the Web-based EDI system implemented from the researched technologies will be installed on the EDI servers owned by corporate customers and enable the exchange of documents between each installed companies.

This paper focuses use context-sensitive spelling error correction using generative adversarial network. Generative adversarial network[1] are attracting attention as they solve data generation problems that have been a challenge in the field of deep learning. In this paper, sentences are generated using word embedding information and reflected in word distribution representation. We experiment with DCGAN[2] used for the stability of learning in the existing image processing and D2GAN[3] with double discriminator. In this paper, we experimented with how the composition of generative adversarial networks and the change of learning corpus influence the context-sensitive spelling error correction In the experiment, we correction the generated word embedding information and compare the performance with the actual word embedding information.

When any data-centric XML documents are stored and managed in RDBMS, schema extracting from XML Schema is an imminent problem. Furthermore, when they are stored in partitioned way on created table, lots of null values will be produced and/or be increased cost for join, so we need a solution to solve these problems. This paper proposes a Schema Hybrid Inlining technique to generate relational schema of XML documents. The suggested technique creates a relational schema based on the XML Schema graph. Also, the technique expands the legacy Inlining method by manual and heuristic processing table generation method of cardinality and in-degree. Then, an ancestor node, terminal node, and creating a new table on the derived relation in this technique. DTD-dependent storage method uses partitioned storing and relation path element information reformed structured-searching method to reduce joining operation cost that is a weak point of it.
