The purpose of this study is to analyze the association among the subject areas of big data research papers. The subject group of the units of analysis was extracted by applying co-citation networks, and the rules of association were analyzed using Apriori algorithm of R program, and visualized using the arulesViz package of R program. As a result of the study, 22 subject areas were extracted and these subjects were divided into three clusters. As a result of analyzing the association type of the subject, it was classified into 'professional type', 'general type', 'expanded type' depending on the complexity of association. The professional type included library and information science and journalism. The general type included politics & diplomacy, trade, and tourism. The expanded types included other humanities, general social sciences, and general tourism. This association networks show a tendency to cite other subject areas that are relevant when citing a subject field, and the library should consider services that use the association for academic information services.

As the need for the use of big data increases, various analysis activities using big data, including SNS data, are being carried out in individuals, companies, and countries. However, existing research on predicting technology market trends has been mainly conducted using expert-dependent or patent or literature research-based data, and objective technology prediction using big data is needed. Therefore, this study aims to present a model for predicting future technologies through decision tree analysis, visualization analysis, and percentage analysis with data from social network services (SNS). As a result of the study, percentage analysis was better able to predict positive techniques compared to other analysis results, and visualization analysis was better able to predict negative techniques compared to other analysis results. The decision tree analysis was also able to make meaningful predictions.

With the rise of the Fourth Industrial Revolution and I-Korea 4.0, both of which pursue strategies for industrial innovation and for the solution to social problems, the real estate industry needs to change in order to make effective use of available space in smart environments. The implementation of smart spaces is a promising solution for this. The smart space is defined as a good use of space, whether it be a home, office, or retail store, within a smart environment. To enhance the use of smart spaces, efficient decision-making and well-timed and accurate interaction are required. This paper proposes a smart space based on platform which takes advantage of emerging technologies for the efficient storage, processing, analysis, and utilization of big data. The platform is composed of six layers - collection, transfer, storage, service, application, and management - and offers three service frameworks: activity-based, market-based, and policy-based. Based on these smart space services, decision-makers, consumers, clients, and social network participants can make better decisions, respond more quickly, exhibit greater innovation, and develop stronger competitive advantages.

Vehicle average speed information which measured at a point or a short section has a problem in that it cannot accurately provide the speed changes on an actual highway. In this study, segment separation method based on vehicle big data for accurate micro-speed estimation is proposed. In this study, to find the point where the speed deviation occurs using location-based individual vehicle big data, time and space mean speed functions were used. Next, points being changed micro-scale speed are classified through gradual segment separation based on geohash. By the comparative evaluation for the results, this study presents that the link-based speed is could not represent accurate speed for micro-scale segments.

Interest in the transition to MyData beyond the use of personal data is high worldwide. In order for the ideology of MyData to be realized, various useful MyData services would be developed in practice. Above all, convergence must be premised for the development of MyData. This study proposed strategies for activating MyData convergence services from four perspectives (BLTS: Business, Legal, Technology, and Social). In particular, the purpose w as to revitalize domestic convergence services by comparing European policies and services, which are the most pioneering in the field of MyData, with the domestic situation. It is expected that this study will provide balanced and progressive ideas in the MyData industry and policies.

최근 국내 외를 불문하고 IT기술의 비약적인 발전에 따라 금융분야에서도 금융과 기술이 결합된 새로운 형태의 금융서비스가 다양하게 개발되고 있다. 그러나, 개인금융시장의 비약적 발전에도 불구하고, 기업금융시장에서의 핀테크 활용은 아직까지 미미한 실정이다. 기업 신용평가는 재무제표 위주의 정태적(static) 과거 정보 위주로 이루어지고 있어 업력이 짧고 규모가 영세한 중소기업의 금융접근에 제약이 존재한다. 또한, 중소기업의 인력이 부족한 상황에서 모든 거래를 일일이 금융기관을 방문하여 처리해야 하는 불편함도 애로사항으로 파악되었다. 이러한 한계를 해소하기 위해 신용보증기금은 빅데이터 활용과 비대면 채널에 주목하였다. 본 보고서는 신용보증기금이 빅데이터와 비대면 채널을 활용하여 중소기업의 금융접근성을 향상시킨 사례에 대하여 소개하고자 한다. 첫 번째로, 신보는 기존에 활용되지 못한 동태적(dynamic) 빅데이터를 활용하여 기업의 현재 새로운 신용평가모형을 개발하였다. 두 번째로, 신보는 중소기업의 금융거래 편의성 향상을 위해 비대면 금융업무 플랫폼을 도입하였다. 신보는 이를, 데이터 수집이 체계적이고 정교해야 하며, 중소기업 관련 데이터가 공유되어야 한다는 정책적 시사점을 발견하였다. 이러한 정책적 시사점을 바탕으로 신보는 이제 기업 데이터 뱅크(Data Bank)로서의 역할을 도모하고 있으며, 더 나은 기업정보 생태계를 구현하고자 한다. 이를 통해 신보의 신기술을 활용한 중소기업 금융접근성 제고 사례가 핀테크를 활용한 공공기관의 금융정책 수립에 유용한 사례가 될 수 있을 것으로 기대한다.

지난 몇 년간 우리는 소셜 검색에 몰두하여 연관검색 및 소비자의 만족을 위해 빅데이터 분석을 하였다. 최근에는 빅데이터 분석이라는 흐름에 맞춰 기업 및 기관별 본연의 정보를 통합하여 효율적인 검색을 할 수 있도록 하는 솔루션을 대거 도입하고 있다. 또한 기업 및 기관에서 가지고 있는 정보는 기존 비정형 데이터로 방대하여 기존의 방법이나 도구로 수집 및 저장 분석이 어려운 실정이다. 이에 공공기관 및 민간기업 등에서는 키워드 중심의 다양한 검색엔진을 개발하거나 도입하고 있으며, 정보 분류의 확대, 메타데이터의 활용, 태그정보의 제공, 개인 맞춤형 서비스 등 고객의 만족도를 제고하기 위한 다양한 방법을 시도하고 있다. 본 연구에서는 기관의 교통 연구와 관련한 일련의 작업 중 행정문서, 연구정보, 유관기관 게시물 등의 통합 빅데이터를 가지고 검색시스템을 구현하였다. 이와 더불어 사용자 사전 및 동의어 사전을 통한 검색 키워드를 데이터베이스에 저장하여 검색 효율성을 제고하는 방안을 제시한다.

Big data analysis, in the large amount of data stored as the data warehouse which it refers the process of discovering meaningful new correlations, patterns, trends and creating new values. Thus, Big data analysis is an effective analysis of various big data that exist all over the world such as social big data, machine to machine (M2M) sensor data, and corporate customer relationship management data. In the big data era, it has become more important to effectively analyze not only structured data that is well organized in the database, but also unstructured big data such as the internet, social network services, and explosively generated web documents, e-mails, and social data in mobile environments. By the way, a meta analysis refers to a statistical literature synthesis method from the quantitative results of many known empirical studies. We reviewed a total of 750 samples among 50 studies published on the topic related as IDT between 2000 and 2017 in Korea.
