Recently, interest in data analysis has increased as the importance of big data becomes more important. Particularly, as social media data and academic research communities become more active and important, analysis becomes more important. In this study, co-word analysis was conducted through altmetrics articles collected from 2012 to 2017. In this way, the co-occurrence network map is derived from the keyword and the emphasized keyword is extracted.

In recent years, "altmetrics", given birth by social media and the academic community, have become a metric source for measuring the academic impact of scientific literature. This study has undertaken a co-word analysis of author keywords in "Altmetrics" articles from the Web of Science database from 2012 to 2017 and used a co-occurrence matrix to create a clustering of the words. "Altmetrics" co-occurrence network map was derived and the research hotspots was analyzed.

Purpose: This study was designed to analyze the behavioral change of knowledge structures and the trends of research topics in the quality management field. Methods: The network structure and knowledge structure of the words were visualized in map form using co-word analysis, cluster analysis and strategic diagram. Results: Summarizing the research results obtained in this study are as follows. First, the word network derived from co-occurrence matrix had 106 nodes and 5,314 links and its density was analyzed to 0.95. Average betweenness centrality of word network was 2.37. In addition, average closeness centrality and average eigenvector centrality of word network were 0.01. Second, by applying optimal criteria of cluster decision and K-means algorithm to word co-occurrence matrix, 106 words were grouped into seven clusters such as standard & efficiency, product design, reliability, control chart, quality model, 6 sigma, and service quality. Conclusion: According to the results of strategic diagram analysis over time, the traditional research topics of quality management field related to reliability, 6 sigma, control chart topics in the third quadrant were revealed to be declined for their study importance. Research topics related to product design and customer satisfaction were found to be an important research topic over analysis periods. Research topic related to management innovation was emerging state and the scope of research topics related to process model was extended to research topics with system performance. Research topic related to service quality located in the first quadrant was analyzed as the key research topic.

Purpose: This study analyzed research trends related to childhood and adolescent cancer survivors (CACS) using word co-occurrence network analysis on studies registered in the Korean Citation Index (KCI). Methods: This word co-occurrence network analysis study explored major research trends by constructing a network based on relationships between keywords (semantic morphemes) in the abstracts of published articles. Research articles published in the KCI over the past 10 years were collected using the Biblio Data Collector tool included in the NetMiner Program (version 4), using "cancer survivors", "adolescent", and "child" as the main search terms. After pre-processing, analyses were conducted on centrality (degree and eigenvector), cohesion (community), and topic modeling. Results: For centrality, the top 10 keywords included "treatment", "factor", "intervention", "group", "radiotherapy", "health", "risk", "measurement", "outcome", and "quality of life". In terms of cohesion and topic analysis, three categories were identified as the major research trends: "treatment and complications", "adaptation and support needs", and "management and quality of life". Conclusion: The keywords from the three main categories reflected interdisciplinary identification. Many studies on adaptation and support needs were identified in our analysis of nursing literature. Further research on managing and evaluating the quality of life among CACS must also be conducted.

Text mining techniques provide valuable insights into research information across various fields. In this study, text mining was used to identify research trends in wood science from 2012 to 2022, with a focus on representative journals published in Korea and Japan. Abstracts from Journal of the Korean Wood Science and Technology (JKWST, 785 articles) and Journal of Wood Science (JWS, 812 articles) obtained from the SCOPUS database were analyzed in terms of the word frequency (specifically, term frequency-inverse document frequency) and co-occurrence network analysis. Both journals showed a significant occurrence of words related to the physical and mechanical properties of wood. Furthermore, words related to wood species native to each country and their respective timber industries frequently appeared in both journals. CLT was a common keyword in engineering wood materials in Korea and Japan. In addition, the keywords "MDF," "MUF," and "GFRP" were ranked in the top 50 in Korea. Research on wood anatomy was inferred to be more active in Japan than in Korea. Co-occurrence network analysis showed that words related to the physical and structural characteristics of wood were organically related to wood materials.

구전(Word-of-Mouth) 활동은 오래 전부터 기업의 마케팅 과정에서 중요성을 인식하고 특히 마케팅 분야에서 많은 주목을 받아왔다. 최근에는 인터넷의 발달에 따라 온라인 뉴스, 온라인 커뮤니티 등에서 사람들이 지식과 정보를 주고 받는 방식이 다양해지면서 구전은 후기, 평점, 좋아요 등으로 입소문의 양상이 다각화되고 있다. 이러한 현상에 따라 구전에 관한 다양한 연구들이 선행되어왔으나, 이들을 종합적으로 분석한 메타 분석 연구는 부재하다. 본 연구는 학술 빅데이터를 활용해 구전 관련 연구동향을 알아내기 위해서 텍스트 마이닝 기법을 적용하여 주요 연구들을 추출하고 시기별로 연구들의 주요 쟁점을 파악하는 기법을 제안하였다. 이를 위해서 1941년부터 2018년까지 인용 데이터베이스인 Scopus에서 'Word-of-Mouth'라는 키워드로 검색되는 총 4389건의 문헌을 수집하였고, 영어 형태소 분석과 불용어 제거 등 전처리 과정을 통해 데이터를 정제하였다. 본 연구는 학문 분야의 발전 궤적을 추적하는 데 활용되는 주경로 분석기법을 적용해 구전과 관련된 핵심 연구들을 추출하여 연구동향을 거시적 관점에서 제시하였고, 단어동시출현 정보를 추출하여 키워드 간 네트워크를 구축하여 시기별로 구전과 관련된 연관어들이 어떻게 변화되었는지 살펴봄으로써 연구동향을 미시적 관점에서 제시하였다. 수집된 문헌 데이터를 기반으로 인용 네트워크를 구축하고 SPC 가중치를 적용하여 키루트 주경로를 추출한 결과 30개의 문헌으로 구성된 주경로가 추출되었고, 연관어 네트워크 분석을 통해서는 시기별로 온라인 시대, 관광 산업 등 다양한 산업군 등 산업 변화가 반영돼 시대적 변화와 더불어 발전하고 있는 학술적 영역의 변화를 확인할 수 있었다.
