Bridge engineering documents have essential contents that must be referenced continuously throughout a structure's entire life cycle, but research related to the quality of the contents is still lacking. XML schema matching is an excellent technique to improve the quality of stored data; however, it takes excessive computing time when applied to documents with many contents and a deep hierarchical structure, such as bridge engineering documents. Moreover, it requires a manual parametric study for matching elements' weight factors, maintaining a high matching accuracy. This study proposes an efficient weight-factor determination method based on an artificial neural network (ANN) model using the simplified XML schema-matching method proposed in a previous research to reduce the computing time. The ANN model was generated and verified using 580 data of document properties, weight factors, and matching accuracy. The proposed ANN-based schema-matching method showed superiority in terms of accuracy and efficiency compared with the previous study on XML schema matching for bridge engineering documents.

The method of effectively merging XML documents becomes necessary, as the use of XML is popular and the collaborative editing is required in the areas such as office documents and scientific documents editing works. As a solution to this problem, in this paper we present a theoretical framework for merging individual editing works by muli-users to a same source document. Different from existing approaches which merge documents themselves when they are merged, we represent editing works with a series of edit operations applied to a source document, which is called a edit script, merge those edit scripts by multi-users, and apply the merged one to the source document so that we can achieve the same effect of merging documents. In order to do this, assuming edit scripts based on insertion and deletion edit operations, we define notions such as static edit scripts, the intervention between edit scripts and the conflict between the ones, then propose the conflict conditions between edit scripts and the method of adjusting edit scripts when merged. This approach is effective in reducing network overhead in distributed environments and also in version management systems because of preserving the semantics of individual editing works.

This paper proposes the way to analyse XML docuements according to the element information. XML documents, which are becoming new standard for expressing and exchanging data in the Internet, don't have defined schema. It is not adequate to directly apply XML documents to the existing relational database or object-oriented database query language. Research on how to extract schema for XML documents and query language is going on actively For users' query, the results could be too many or too less. It is important to give the users adequate results. Our proposed analysis method can be reduced or extended to correspond to the users' query more flexibly.

The number of XML documents, which are widely used as a standard method for information expression and exchange in the web-based environment, increases rapidly along with the growing production of large XML documents. Many studies have been made to store and retrieve these XML documents on RDBMS, among which Shared Inlining storage method has a higher level of retrieval efficiency. The Shared Inlining method is the technique that analyzes the DTD information and stores the XML document in RDBMS by dividing for each node component. This study proposes the technique to resolve the overlapping problem that occurs in the element with several child nodes in the existing Shared Inlining method. The suggested method stores the XML document in the Shared Inlining structures appropriate to the DTD definition and enhances the accuracy of retrieval.

Until now the XML document is allowed users to access the whole content of it However, for some applications such as those in the field of electronic commerce, there are cases that the whole content should not be delivered. Therefore, access authorization is required for XML documents in order to protect illegal accesses to some critical parts of them. In this paper. we design and implement a system which authorizes users to XML documents and controls access to them based on the access rights. We set the user group as a basic unit of the authorization subject and the element of an XML document as a basic unit of authorization object The owner of a document authorize; user groups to access the elements of it When an XML document is accessed, the access rights of the requester are checked using an access control list and only the authorized parts are delivered_ As the result, we can authorize XML documents, which has been previously impossible.

XML is good at representing data with hierarchical and self-describing structure. There is no inherent semantics with XML. However, semantics of XML has come up with us as XML is used in wide and advanced applications. This paper surveyed semantics in XML data processing environment. XML semantics can be categorized into four groups according to its usage; structural semantics, relational semantics, extended semantics, and semantic web. Relational database is still a good alternative for storing and managing large volume of XML documents. We propose an extended relational semantics in order to exploit it in managing XML documents such as query processing.

There have been many filtering systems covering mail or news. Documents filtered by them consist of general text or HTML. XML is emerging as a new standard for information exchange. So, filtering systems need new approaches in dealing with XML documents. Our system suggests a method to describe user profiles with XML's ability to represent schema and structure. An user profile is made from DTD information and it is supposed to point the specific part of a document conforming to the DTD. More, it is different from the existing systems in extracting part of a document. An user profile is reflected in XML query to get part of an XML document.

Many people have been building HTML documents due to rapid spread and growth of web. However, HTML has limits in satisfying user's requirements, so that XML has emerged. In this paper, we design and implement student information management programs and presentation methods for maintaing the general student life archives and the analysis of results of examinations using XML and web browser. We define a XML DTD for general student life archives, and build XML documents. A private student life archive is printed from XML documents on the web using XMLDOM, DATA-BINDING, and XSL. Also, personal items and a roll book of a class can be printed and searched. In order to analyze the result of examinations we define DTD and build XML documents according to the DTD.

As business-to-business electronic commerce becomes activated, usage rate of standard electronic documents is rapidly increasing. Types and forms of standard documents exchanged between businesses have also been changed. Instead of EDI documents, mainly used in the initial phase, XML documents have been actively used recently. However, most framework standards for XML documents just specify basic syntax rules, messaging protocols, and standard documents. As a result, it has been usually difficult to procure efficiency and effectiveness in developing new standard electronic documents. Reflecting the experiences of developing UN/EDIFACT, UN/CEFACT provides a methodology and library for reusing standard data items as components when defining electronic documents. However, much additional effort is required for applying the methodology and library to the development process. In order to improve this situation, this paper proposes a system for supporting the development process by reusing various resources of registries/repositories, focusing on UN/CEFACT submission forms for standard electronic documents.

Recently, due to the development of internet based information technology, organizations Is utilizing electronic documents as important media for processing business work and sharing Information exchange. These electronic documents are mos4 form like documents and are important user interfaces for business applications. But, presently web-based electronic documents are lack of the characteristics that are taken in documents, such as document writing rules and its workflow. This Paper deals with XML-based business document that include the structure, data, and logic and proposes the framework for validating the data and logic included within business documents using Prolog.
