This study proposes a way to timely forecast open government data (OGD) demand(i.e., OGD requests, search queries, etc.) by using keyword network analysis. According to the analysis results, most of the OGD belonging to the high-demand topics are provided by the domestic OGD portal(data.go.kr), while the OGD related to users' actual needs predicted through topic association analysis are rarely provided. This is because, when providing(or selecting) OGD, relevance to OGD topics takes precedence over relevance to users' OGD requests. The proposed keyword network analysis framework is expected to contribute to the establishment of OGD policies for public institutions in the future as it can quickly and easily forecast users' demand based on actual OGD requests.

Public open data is a database or electronic file produced by a public agency or government. The government is opening public data through the open data portals and individual agency websites. However, it is a reality that there is a limit to search and utilize desired public data from the perspective of data users. In particular, it takes a great deal of effort and time to understand the characteristics of data sets and to combine different data sets. This study suggests the possibility of interlinking between data sets by analyzing the common relationship of item names held by public data. The data sets are collected from the open data portal, and item names included in the data sets are extracted. The extracted item names consist of formal context and formal concept through formal concept analysis. The format concept has a list of data sets and a set of item name as extent and intent, respectively, and analyzes the common items of intent end to determine the possibility of data connection. The results derived from the formal concept analysis can be effectively applied to the semantic connection of the public data, and can be applied to data standard and quality improvement for public data release.

Since 2013, Korean government announced 'government 3.0' to promote public data open policy. As a result, related websites were constructed by the government. Using these websites and public data open cases, we introduced and analyzed current domestic public open data status and case analysis in Korea Republic. For websites, websites such as 'seoul open data plaza' were selected. For related cases, websites such as 'http://www.zillow.com' and 'http://blog.safecast.org' were selected. For domestic cases, a casebook which produced by Korea 'National Information Society Agency' were used. Domestic cases referred to this article were based on this book.

이 연구는 우리나라 정부의 공공데이터 공개 제도에 따른 공공데이터 품질관리체계를 이해하고, 공공기관이 신뢰성 있는 데이터를 위해 품질 점검을 시행하면서도 효과적인 관리를 하기 위한 방안에 관한 것이다. 공공데이터법과 공공데이터 품질관리체계를 이해하고, 저품질 공공데이터의 오류와 발생원인에 대해 알아본다. 오류 데이터 분석을 통한 보안위협에 따른 위험 분류를 통해 효과적인 대응방안을 도출하는 것을 목표로 한다. 이를 위해 공공데이터를 데이터 품질 점검하여 도메인별 오류데이터를 살펴보고, 오류데이터 발생원인에 대한 분석을 통해 보안위협과 공공데이터를 사용하는 사용자 측면과 기관 측면의 보안 문제를 분류하였다. 분류된 오류 발생원인별 보안문제를 기준으로 데이터 품질관리를 통한 개선방향을 제시하고, 품질관리 오류 개선방향별 데이터보안 정책별 보안기술을 비교 정리하여, 데이터 보안기술을 통한 품질관리 오류 개선 연계 대응방안을 제안하였다.

정부의 공공데이터 활성화 전략에 의해 행정기관과 공공기관의 정보공개 및 재이용이 활발해 지고 있다. 이러한 분위기와 함께 민간에서의 공공데이터 활용이 점점 늘어나고 있다. 하지만 당초 기대치에 못 미치는 성과와 공공데이터 개방하는 기관에는 정보화시스템을 운영하는 비용은 증가하였다. 따라서 상대적으로 민간에서 선호하는 문화관광 공공데이터를 통해 공공데이터의 효율성을 분석한 후 시사점을 도출한다.

This study examines the current state of library related data opened through public data portals, and analyzes how much data is being utilized according to the type of releasing organization, and open level. In addition, we analyzed the subject cluster of data and the centrality of data by performing PathFinder Network analysis using keywords assigned to data by dividing the releasing subject into local government and national/public institutions. Based on this, the subject area of library - related data disclosed by local governments and national/public organizations is understood. And identify the main open body that should be opened first by linking with data utilization analysis result and then suggest implications for future improvement in connection with library big data business.

Data of central government and local government was collected automatically from the public data portal. And we did the multidimensional analysis based on various perspective like file format and present condition of public data. To complete this work, we constructed Data Warehouse based on the other countries' evaluation index case. Finally, the result from service level evaluation by using multidimensional analysis was used to display each area, establishment, fields.

요우커를 중심으로 한 한류 열풍은 연예인, 미디어 콘텐츠 시장을 넘어서 한국산 제품에도 큰 영향을 미치고 있다. 특히, 화장품을 비롯한 뷰티 관련 제품은 가장 대표적인 시장으로 주목 받고 있다. 본 논문에서는 공공데이터 및 소셜 웹 데이터를 이용하여 화장품 관련 기업의 비즈니스를 위한 뷰티 트렌드 분석 서비스를 제안한다. 소셜 웹 데이터는 국내외 뷰티 시장에 대한 제품인지도를 중심으로 분석되며, 공공데이터는 국내에서 유통되는 화장품에 대한 안정성을 중심으로 분석한다.

In Korea, starting with the Government 3.0 Policy, the utilization of public data as an important driving force to promote economic growth has been highlighted as a major issue. However Korea is currently only able to open and provide accumulated data stored in the public domain. To resolve this issue, we need to not only open and provide public information, but also to create new information by linking the data and developing related services. Thus, this study analyzes the linkability of public information and provides lists of the linkable public data. In order to do this, we first have performed preconditioning processes on the accessibility and workability of the data. Next, we have deduced the major keywords in public data through analyzing the morphemes, and then the core keywords (Top 10) and their linkable keyword lists through an analysis of social networks. Based on the outcome of this study, a subsequent study will deduce new information by linking the public data and creating various services and information contents. Furthermore, not only conceptual but also practical linking measures need to be created, and a related law must be prepared.

The study aims to analyze the Public Data Act and provide alternative strategies for public data management. It conducts an extensive literature review based on a multidisciplinary approach and discusses the terms, public data and synonyms from the Public Data Act, and other related laws while also studies and traces the history of related regulations. The significance of the Public Data Act is analyzed and the major contents of the Act are examined, particularly, the contents that describe relevant committees. As a result, the article discusses five issues: relation between regulations, ambiguity of decision-making standards, 'professionality of a public data supply officer, low quality of public data, and lack of records and archives management.
