Because of the recent boost of the application services utilizing electronic tags, researches about the electronic tag management are widely being proceeded. In order to manage the object information collected from various electronic tags XML based data process, which is widely used on the web, is being demanded. Thus, in this paper, we are defining the re-usable object typer that is often used in this business area. Utilizing both the data type we defined and the Core Event Type defined from EPCIS Spec, we designed the scheme matching the object data model of merchant shipping field.

본 논문에서는 XML 문서의 자동변환을 위해 2단계의 상향식 매칭 방법을 제안한다. 제안된 방법은 단말 노드 사이의 유사도 비교를 통해 임계값을 넘는 후보 매칭집합을 결정하고, 단말노드가 포함되어 있는 경로의 유사도 비교를 통해 적절한 일대일 매칭을 추출한다. 특히, 노드 사이의 유사도 비교를 위해 축약어 사전, 일반 동의어 사전, 도메인 온톨로지를 적용한다. 실제 전자상거래용 XML 스키마를 대상으로 실험한 결과 제안된 방법은 평균적으로 97%의 정확률을 보였다.

본 논문은 점증적으로 갱신되는 온톨로지에 기반한 스키마 매칭 알고리즘을 제안한다. 스키마 매칭에 사용되는 온톨로지는 전운가에 의하여 작성된 정적인 것으로 모든 어휘관계를 포괄하기는 힘들다. 제안된 방법은 이전의 매칭 결과와 사용자 피드백에 따라 점증적으로 온틀로지를 갱신하여 매칭의 성능을 향상시킨다. 특히, 제안된 온톨로지는 분할, 병합 관계를 기술하고 있어 단순한 애칭관계분만 아니라 복합매칭관계 추출을 가능케 한다. 성능평가를 위한 실험결과 점증적 온틀로지의 적용이 매칭 성능을 매우 향상시킴을 알 수 있었다.

When using Medical Information Retrieval services, a typical retrieval method is to use the Anatomic Therapyutic Chemical Classification (ATC) code. Traditional ATC code-based medical information retrieval is very useful for single ingredient product retrieval with single ingredient. However, in the case of complex, retrieval errors often occur. The cause of this problem is that ATC code-based retrieval proceeds by pattern matching ATC code.In this work, we design the mapping scheme based on ATC code by analyzing the requirement scenarios for retrieval based on main ingredient in ATC code-based retrieval. the mapping scheme based on ATC is a schema that stores the ATC code of the complex and all the ATC code of the single agent included in the complex. ATC code-based retrieval using this schema retrieves a complex as ingredient of a single ingredient product, thus having higher accuracy than existing methods. the mapping scheme based on ATC is expected to increase the efficiency of doctors' prescription of patients and increase the accuracy of drug safety use services.

Recent growth of the geospatial information on the Web has made it possible to easily access a wide variety of geospatial information. An integration of different geospatial objects consists of the following three steps; extracting geospatial objects from the maps, converting the coordinate system and discovering pairs of objects that represent the same real-world entity in the two maps. This paper deals mainly with the third step to correspond conjugate objects and four matching types and criteria is presented. The techniques designed and developed can be utilized to efficiently integrate distributed heterogeneous spatial databases such as the digital maps and POIs from other data sources. To achieve the goal, we presented four types and criteria for the matching schema. The main contributions of this paper are as follows. A complete process of integrating data from maps on the Web is presented. Then, we show how attributes of the objects can be used in the integration process.

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.

본 연구는 교량 시설물의 재난방지를 위한 정보시스템의 구축에 있어 선행되어야 하는 교량 구조계산서 항목 저장정보의 질적 향상을 위해 XML 스키마 매칭 기법을 효율적으로 활용할 방법에 대해 제시하였다. 이를 위하여 XML 스키마 매칭에 사용되는 가중치 변화에 따른 매칭 정확도를 나타내는 데이터를 구축하고, 이를 활용하여 데이터 마이닝 기법 중 하나인 의사결정나무 모델을 구현하여 교량의 형식, 문서가 포함하고 있는 항목의 수, 문서를 작성한 회사에 따라 달라질 수 있는 최적의 가중치를 지동으로 선정할 수 있는 프로세스를 제안하였다. 의사결정나무 모델을 통해 결정한 매칭 가중치는 이전에 비하여 약 10% 정확도 상승효과가 있음을 알 수 있었다.

In order to automate the process of mail sorting by delivery sequence, it is necessary to prepare a postal address database and to interpret written addresses on the mail-pieces with the database and OCR technology. The address database is a critical factor of automation and informatization of postal service since it could be used not only in address recognition but also in various mail processing. In this study, we design the schema of postal address database, design the postal address file based on it and explain the method of address interpretation and retrieval using it. We analyze infonnation requirements for transformation of postal address into the standardized format and consider them in the process of design. The postal address file can be used by address matching or retrieval system as well as by Hangul address recognition system for automation of delivery sequence mail-sorting.

Recently, IoT can provide a service considering user's convenience by configuring the inside of the home as a smart environment. However, the existing system can not change the configuration of the home smart environment by the user, and there is a problem in compatibility between the server and the heterogeneous device. In this paper, we propose a system to reconfigure the relationship between the device and the server in the smart home environment to solve that. In a smart home environment, The user can add and delete devices through the application. In addition, when a new device is added, the server searches the schema for the device and establishes an automatic relationship. This makes it possible for the user to easily change the configuration of the smart home environment.

The mediator-based system integrates heterogeneous information systems with the flexible manner. But it does not give much attention on the query optimization issues, especially for the query reusing. The other thing is that it does not use standardized metadata for schema matching. To improve this two issues, we propose mediator-based Distributed Information Integration System (DIIS) which uses query caching regarding performance and uses ISO/IEC 11179 metadata registry in terms of standardization. The DIIS is designed to provide decision-making support, which logically integrates the distributed heterogeneous business information systems based on the Web environment. We designed the system in the aspect of three-layer expression formula architecture using the layered pattern to improve the system reusability and to facilitate the system maintenance. The functionality and flow of core components of three-layer architecture are expressed in terms of process line diagrams and assembly line diagrams of Eriksson Penker Extension Model (EPEM), a methodology of an extension of UML. For the implementation, Supply Chain Management (SCM) domain is used. And we used the Web-based environment for user interface. The DIIS supports functions of query caching and query reusability through Query Function Manager (QFM) and Query Function Repository (QFR) such that it enhances the query processing speed and query reusability by caching the frequently used queries and optimizing the query cost. The DIIS solves the diverse heterogeneity problems by mapping MetaData Registry (MDR) based on ISO/IEC 11179 and Schema Repository (SCR).
