대부분의 빅 데이터 분석 결과는 문장으로 다듬어진 보고서로 결과를 제시하기보다는 비주얼라이제이션으로 결과를 보이고 보는 사람이 갖고 있는 배경지식과 통찰력에 따라 의미 있는 내용을 도출할 수 있도록 한다. 본 고에서는 공공 데이터와 비주얼라이제이션의 중요성을 알리기 위한 국회의원 투표 성향 분석 프로젝트를 소개한다. 우리나라 국민이라면 누구나 관심을 가질만한 국회의원의 성향을 파악하는 것을 세부 목표로 하고 18대 국회의원의 본 회의 회의록으로부터 투표 데이터를 수집하여 유사한 투표성향을 가진 국회의원을 가깝게 배치하여 누구나 쉽게 의원간의 유사성을 알 수 있도록 하였다. 데이터 수집부터 분석모델 개발과 웹 페이지를 만들기까지의 프로젝트 진행과정에서 모델의 수정이 필요했으며 왜 그러한 선택을 했는지를 설명한다.

Nowadays various public data have been serviced to the public. Through the opening of public data, the transparency and effectiveness of public policy developed by governments are increased and users can lead to the growth of industry related to public data. Since end-users of using public data are citizens, it is very important for everyone to figure out the meaning of public data using proper visualization techniques. In this work, to indicate the significance of widespread public data, we consider UN voting record as public data in which many people may be interested. In general, it has high utilization value by diplomatic and educational purposes, and is available in public. If we use proper data mining and visualization algorithms, we can get an insight regarding the voting patterns of UN members. To visualize, it is necessary to measure the voting similarity values among UN members and then a social graph is created by the similarity values. Next, using a graph layout algorithm, the social graph is rendered on the screen. If we use the existing method for visualizing the social graph, it is hard to understand the meaning of the social graph because the graph is usually dense. To improve the weak point of the existing social graph visualization, we propose Friend-Matching, Friend-Rival Matching, and Bubble Heap algorithms in this paper. We also validate that our proposed algorithms can improve the quality of visualizing social graphs displayed by the existing method. Finally, our prototype system has been released in http://datalab.kunsan.ac.kr/politiz/un/. Please, see if it is useful in the aspect of public data utilization.

OLAP은 데이터 마이닝, 데이터 비주얼라이제이션, 데이터웨어 하우징 등의 최신 의사결정지원 기술과 마찬가지로 전반적인 비즈니스 인텔리전스 프레임웍의 핵심 컴포넌트중 하나이다. 하지만 시스템 환경이 복잡해지고, 사용자들의 요구가 다양해짐에 따라 하나의 제품군이 모든 사용자 업무를 지원한다는 것은 무리이다. 이를 위해 각 제품들은 상호 통합 및 연계를 그 해결책으로 제시하고 있다.

Among the properties of new media art works, interaction with audience has now become a big issue, and its influence to general arts, in particular media art, is being stressed more and more. Under the this influence, various experimental works using digital media are being produced and having a try to combination of art and multimedia technology on the network. This paper analyses studies about netart and suggests visualization expression of color data to be interactive between users and art works. The work is to make formative elements based fluid shapes on the analysis of color data extracted from images. This is a new experiment in picturesque expression of data and aesthetic visualization of data.

This thesis represents the integrated 3D DEM using both the process of satellite image and the real value of topographic maps. This DEM is draped on satellite image processed to improve representations of the real world. The 3D visualization and 3D animation with satellite imagery data enables to depict more vivid and realistic world. The paper also describes and implements the natural environmental/ecological information system that consists of 7 modules to manage environmental data systematically through an enhanced user interface. We make use of topographic map, satellite imagery data and several thematic maps. Each module has a user interface enabling to assist particular needs of decision-making for ecological/environmental assessments associated with spatial analysis of ecosystem and classification of the environmental status quo and other purposes.
