  • Most metadata quality measurement employ simple techniques by counting error records. This study presents a new quantitative measurement of metadata quality using advanced weighting schemes in order to overcome the limitations of exiting measurement techniques. Entropy, user tasks, and usage statistics were used to calculate the weights. Integrated weights were presented by combining these weights and were applied to actual journal article metadata. Entropy weights were found to reflect the characteristics of the data itself. User tasks presented the required metadata elements to solve user's information need. Integrated weights showed balanced measures without being affected by the influence of error elements, This finding indicates the new method being suitable for quantitative measurement of metadata quality.

  • 2002년 10월 유럽통계협회는 품질지수개발을 위해 협회소속국가들이 연합하여 특별연구팀을 발족시켰다. 이 팀의 주목적은 유럽통계협회에서 생산되는 자료의 품질을 측정하기 위해 대표성이 있으며, 계산하기 쉽고, 이해하기 쉬운 지수를 개발하는 것이었다. 유럽 통계협회는 연구팀에서 개발한 지수를 이용하여 내부품질보고서를 작성하도록 결정하였다. 개발된 풀질지수들은 유럽 통계협회 소속 국가에 의해 생산된 통계에 적용하기 적합해야하며 유럽전체를 위해 Eurostat 이 보유하고 있는 통계에도 적합해야한다. 그러므로 지수들은 각 국이 합의한 용어, 공식, 변수, 도메인, 분석의 정도를 고려하여 개발되도록 하였다. 이러한 지수는 정기적으로 생산되도록 규정하고 있으며 이 규정이 지켜지기 위해서는 동일한 변수, 공식 통이 적용되어야함은 물론이고 시계열의 유지를 위해 관련된 메타데이터가 제공되어야한다. 서로 다른 조사결과로부터 관련된 통계량의 측정과 개념들간의 차이를 확인하기 위해서 메타데이터는 반드시 필요하며 품질보고서가 있는 경우 많은 도움이 릴 것이다. 본 연구에서는 동계생산자의 관점에서 본 각각의 품질 요소에 따라서 생산된 다양한 통계의 풀질을 평가하기 위해서 개발된 일련의 표준화된 품질지수를 제시할 것이다. 각 지수들의 정의와 가장 대표적인 지수산출을 제안하고 지수산출을 위해 필요한 메타데이터를 선명한 것이다.

  • The Metadata are used for the reuse of core information, distribution and management, protection of copyright and prevention of overlapping investment. Serious game consists of multi-hierarchial multimedia data. And quality information is very important for selection according to the purpose of the game. In this paper, we designed the serious game metadata schema, including multi-media characteristic information and measurable quality information. This study will lay the groundwork for the development of metadata system which can provide serious game users with reliability through quality information, and with compatibility through multi-media characteristic information. Furthermore, we hope this study will be helpful to stable growth in serious game industry.

  • Due to the massive increase of data that should be managed, the problems in data quality management have been issued. In addition the lack of integrated management of the data causes duplication of data, low qualify services, and, missing data. To overcome these problems, this study attempts to examine the way of the data qualify management. To do this, metadata was defined, and its current management status in various view points was analyzed, and finally the metadata management was applied to the container terminal. for the "A" container terminal, we performed data standardization, and reflected major constraints and developed the pilot metadata repository. The contributions of this study are in improvement of the data qualify in the container terminal, and its practical application with metadata management method. Limitations of this study is its partial implementation of the metadata management to the company and interoperability of the metadata management for business to business data integration for the future research.

  • In companies competing for today's information society, Data quality deterioration is causing a negative influence to generate company competitiveness fall and new cost. A lot of Preceding study about data qualify have been proceeded in order to solve a problem of these data qualify deterioration. Among the sides of data qualify, it has been studied mainly on qualify of the data valve and quality of data service that are the results quality concept. However. this study studied structural qualify of the data which were cause quality concept in a viewpoint of meta data management and presented data quality management maturity model through this. Also empirically this study verified that data quality improved if the management level matured.

  • Data quality management is an important issue these days. Improve data quality by providing consistent metadata. This study presents algorithms that facilitate standard word dictionary management for consistent metadata management. Algorithms are presented to automate synonyms management of database metadata through web dictionary crawling. It also improves the accuracy of the data by resolving homonym distinction issues that may arise during the web dictionary crawling process. The algorithm proposed in this study increases the reliability of metadata data quality compared to the existing passive management. It can also reduce the time spent on registering and managing synonym data. Further research on the new data standardization partial automation model will need to be continued, with a detailed understanding of some of the automatable tasks in future data standardization activities.

  • Today, Educational serious games are occupying a large portion of the serious game market but there is a lack of the quality evaluation systems for providing useful quality evaluation information about educational serious game to user or developer. Although the existing metadata management system for serious game is developed, the system had not provided a function to manage the quality evaluation information for educational serious game. Therefor the development of quality evaluation management system of educational serious game is a very important challenge. We proposed design of the system for managing a metadata and a quality evaluation for educational serious game. The advantage of our system is that the system provide a lot of reliable useful information for general users and developers, and support an easy and convenient tool to manage the metadata and quality information to managers.

  • During the past 10 years, serious game industry has been growing steadily. But the system which could stably and reliably provide metadata information and quality information related to serious game remained unexploited. Existing systems only support the basic management functions of metadata search centered. Therefore, we have developed an integrated system to manage the quality information of serious game as well as to improve the inconvenient details of the existing systems. And we designed quality evaluation elements and quality information supply-methods, and linked up them to the system. Furthermore, we conducted user's satisfaction assessment survey on the use of the system. The advantage of the system is that the system provide a lot of useful information for general users and developers, and support a tool to manage all information related to serious game by easy and convenient method for managers.
