뉴스 헤드라인에 제3자의 발언을 직접 인용해 전언하는 이른바 '따옴표 저널리즘'이 언론 보도의 객관주의 원칙을 해치는지는 언론학 및 뉴스 구독자에게 중요한 문제이다. 이 연구는 온라인 포털사이트를 통해 실시간 유통되는 한국어 기사의 정확성을 판별하기 위한 기계학습(Machine Learning) 모델을 제안한다. 이 연구에서 제안하는 모델은 Edit Distance와 FastText 기법을 활용해 기사 제목과 본문 내 인용구의 유사성을 측정하고, XGBoost 모델을 활용해 최종 분류한다. 아울러 이 모델을 통해 229만 건의 뉴스 헤드라인에 대해 직접 인용구가 포함된 기사가 취재원의 발언을 주관적인 윤색없이 독자들에게 전하고 있는지를 판별했다. 이뿐만 아니라 딥러닝 기반의 KoELECTRA 모델을 활용해 기사의 제목 내 인용구에 대한 감성 분석을 진행했다. 분석 결과, 윤색이 가미되지 않은 직접 인용형 기사의 비율이 지난 20년 동안 10% 이상 증가했으며, 기사 제목의 인용구에 나타나는 감정은 부정 감성이 긍정 감성의 2.8배 정도로 우세했다. 이러한 시도는 앞으로 계산사회과학 방법론과 빅데이터에 기반한 언론 보도의 평가 및 개선에 도움을 주리라 기대한다.

We selected core documents from enormous number of documents by analyzing citation relation of papers or patents including direct citation and indirect citation. Then we tried to creat the technology evolution path from citation network tree. By applying the method to the patent DB of OLED (Organic Light Emitting Diode), we obtained genealogical citation network of core patents of OLED. We analyzed how the one of OLED technology was transferred to the semiconductor related technology and we named the process of transition as 'technology evolution path' of OLED technology. And we also analyzed the genealogical citation network of papers on graphene. From the analysis, we found that the weight count method including indirect citation was better in evaluating the value of technology of a paper than the times cited method.

The citation analysis is not applied to group measurements but to individual papers finding their impact factors among citation chains which are created by tracing citing-cited relationship between any two papers in data set. The individual impact factor is measured by adding each value derived from citation chain. Each paper's impact factor index is calculated by adding the values of each index by direct citing-cited relationship, and the values of each impact factor made by indirectly influencing to the papers in the citation chain. The research introduces a grace period, in which the system holds the papers not cited by other papers yet, but are expected to be cited within this period. Eventually not cited papers after the grace period would be eliminated by the system. The experiment suggests a reasonable database in which the highly influenced papers are gathered, and could be serviced in stead of buying databases filled with worthless not-cited-papers.

한국암석학회에서 발간하는 암석학회지에 지난 10년간 수록된 논문들이 여러 학술지에 얼마나 인용되고 있는지에 대한 통계조사를 실시하였다 대상학술지는 암석학회지 자체를 비롯하여 SCI 등재 국제학술지, 그리고 관련된 분야에서 국내의 대표적 학술지라고 생각할 수 있는 지질학회지, Geosciences Journal, 자원환경지질, 지구과학회지를 대상으로 하였다. 결과를 보면 지난 10년간 암석학회지에 수록된 논문의 수는 논평과 단보를 포함하여 총152편이며 가장 많은 논문을 게재한 저자는 김형식으로 21편의 논문을 게재하였다 암석학회지 논문의 피인용 회수는 총370회로 암석학회지에 가장 많은 158회 인용되었으며. SCI 학술지에는 46회 인용된 것으로 조사되었고, 다른 국내 학국지 중에서는 지질학회지에 72회로 가장 많이 인용되었다 가장 많은 피인용 빈도를 보인 논문은 Liu(1993)로 총 27회이고, 가장 많은 피인용 회수를 보인 저자는 권성택으로 81회이다. 다른 국내학술지들의 피인용 통계자료가 없어 직접적인 비교를 하기는 어렵지만 관련 분야의 학술지 중에서는 피인용 정도가 정상급 수준이라고 판단된다. 그러나 아직 여러 기준으로 볼 때 수준급인 국제학술지와는 차이가 있으며 더욱 개선되어야 할 것으로 생각한다.

청자를 직접 대면한 상황에서 1인칭 화자는 {X, Y, 말했다}의 인용구조를 갖추지 않은'[...]고'의 '유사인용문'을 사용하여 주관적 관점을 표현한다. '-다고'로 종결되는 유사인용문 형식이 인용문의 화법과 유사한 기저구조를 지니는 것으로 보고, 화법구조상에서 관점문과 보고문의 의미적 속성을 밝혀나가는 과정에서 유상인용문의 발화 효과와 화자의 발언의도를 설명한다. 화자가 취하는 관점의 선택에 따라 1인칭 화자인 [나] 이외에 다른 제 3 의 주체, 사회적 구속력 등이 화자의 배경지식에 자리잡는 것을 가능세계의 논리적 분할의 측면에서 구분하고 이것이 유사인용문 화자의 발언 동기에 반영되는 정도의 차이에 따라서 화자의 단언적 태도와 완곡의 태도가 각각 실현되는 것임을 보인다.

This study presents a new method to evaluate patents by public R&D program using patent citation network analysis. I used forward citation, degree centrality, betweenness centrality and page rank as the dependent variables which represents the quality of patents. I used primary independent variable as a dummy of public R&D program and controlled patents characteristics, applicant characteristics, technological characteristics and year effect. The empirical result shows that the patents of public R&D program is superior to other patents in regard to the number of forward citation, the degree centrality, the betweenness centrality and the page rank. This empirical result implies that patents of public R&D program directly and effectively connects technologies. Also patents from public R&D program connects important technologies.

The purpose of this study is to investigate interdisciplinary changes in the field of Archives and Records Management in Korea. For this purpose, this study analyzed disciplinary attributes of citing and cited references appeared in the Journal of the Korean Society of Archives and Records Management during the period, 2001-2011. One hundred and ninty five research articles and two thousands nine hundreds ninty seven cited references were analyzed to find the degree of interdisciplinarity by using direct citation and Brillouin index. Finally, the interdisciplinary changes of source literature and cited references in Korean archival science during the period were suggested.

Although it has been a long subject of study why researchers prefer some cited documents to others, the existing relative researches have had a variety of perspectives on the nature and complexity of the citation behavior and not provided a complete answer to this question. In particular, Korea researchers mainly used statistical analysis of bibliographic information, which has limitations in revealing dynamic and complex cognitive aspects of the citation process. In this study, I investigate the citer perception of citing motives and bibliographic factors through survey and compared the responses according to the researchers' characteristics. After extracting the 22 motivations and 21 factors through the literature analysis and configuring a 5-point Likert scale questions, I conducted a survey in the wat of an e-mail attachment. From the SPSS 22.0, the frequency analysis, t-test, and one-way ANOVA were performed on the 354 valid samples. As a result, it is found that supporting is considered the most important citing motive and social connection, self-citation have little influence. In the case of bibliographic factors, the journal's reputation was recognized the most influential factor and the number of pages and authors was the least. Significant differences in fields of study and research careers were showed in some parts. These results can substantiate earlier studies, determine whether the factors assumed influential in selecting references were intended, and suggest the search point to the specialty library or academic database.

The purpose of this study was to Identify the similarities and differences between the hyperlinking practice of scholarly e-journal authors and conventional citing practice. 230 scholarly e-journal articles containing at least two hyperlinks and their authors were selected as the sample for the study. A mail questionnaire survey of the authors of the sampled e-journal articles was conducted (with a response rate of $70\%$) to collect quantitative data on the authors' hyperlinking motivations. In addition, a content analysis of the e-journal articles and the source documents hyperlinked in the articles was conducted to examine the patterns of hyperlinks. A comparison between the quantitative results of this hyperlinking study and previous citation studies was made. The results revealed not only some similarities but also several significant differences between them.
