본 연구는 최근 2년(2019.12.1.~2021. 11.30)간 빅카인즈를 이용하여 '메타버스 AND 비대면 교육' 키워드가 포함된 뉴스 검색 결과 1148건을 바탕으로 관계도 분석, 연관어 키워드 빈도수 및 연관어 가중치 분석을 하였다. 첫째, 관계도 분석에서 가중치 '5'로 적용한 12개의 키워드 가중치로 코로나19(64), 아바타(43), 코로나(22), 유니버스(21), 게더타운(15), 패러다임(12), 신입사원(12), 로블록스(7)로 나타났다. 둘째, 연관어 키워드 월간 빈도수로는 2019.12~ 2020.9(0건), 2020.10(1건), 2021.3(19건), 2021.4(34건), 2021.6(72건), 2021.9 (196건), 2021.11애는 233건으로 급격하게 증가하였다. 셋째 키워드와의 연관성(가중치/키워드 빈도수)으로 코로나19(113.96/515), 가상세계(67.75/ 344), 메타버스(58.36/103), 메타(49.8/5730), 가상공간(45.57/380) 순이었다. 이 분석 결과에서 위드코로나 시대의 비대면 교육으로 메타버스에 기반을 둔 가상공간 활용 교육은 더욱 증가될 것으로 예상된다.

일반적으로 인간이 사용하는 몇 개의 주요단어를 이용하여, 문서의 분야나 주제어가 되는 일본어 키워드를 추출하는 점에 주목한다. 먼저, 학술논문에서 저자 자신이 부여한 키워드 중 분야 명이나 주제어가 문서 중에 출현하지 않는 경우를 분석하고, 단어의 개념정보를 기초로 복합어 생성규칙을 구축한다. 문서 의미와 상관없는 키워드의 추출을 억제하기 위해 중요도 결정법을 새롭게 제안한다. 추출된 키워드의 타당성 검사를 위해 자연.음성언어에 관한 일본어 논문 65파일의 타이틀과 초록부분을 이용하여 추출된 키워드의 타당성에 대한 실험을 한 결과 추출 정밀도는 중요도의 상위 1개를 출력한 경우 75%가 되어 제안방법의 유효성을 확인할 수 있었다.

The purpose of this study is to analyze the research trends in domestic related to gifted counseling by utilizing Sementic analysis methods. For papers of gifted education in korea, KCI(Korea Citation Index) rated journals were selected 83 pieces published in journals were collected and the Sementic Network Analysis(SNA) way was utilizing for keyword frequency and Centrality Network Analysis throughout a variety of research articles using krkwic and Ucinet6.0. The results are as follows. first, the analysis appeared that the trends of paper keywords from highest frequency of appearance keyword in papers focused on four keywords: perfectionism, career, counseling, and the science gifted. second, Analysis of annual trends from 2001 to June 2018 showed that the top keywords were as follows: the gifted underachievers, the perfectionism, the gifted students of Science, and the science gifted students. the rising keywords were perfectionism, twice-exceptional students, and gifted parents, and the keywords of gifted students and general students showed a tendency to decrease. Consequently, gifted counseling research should be done from various perspectives.

The purpose of this study is to investigate the development direction of future scholarship by analyzing recent research trends in collection development and management field using keyword network analysis. Data was collected from four journals in library and information science field during period of 2003 to 2017. Related articles of Collection Development and Management field were retrieved, and author keywords were extracted from selected papers. Keyword network analysis using NetMiner4 program was performed based on frequency analysis, connection-centered analysis, and parametric analysis. The analysis covers all sections from 2003 to 2017 to look at the changes in research over time, and three sections on five-year basis. As a result, main keywords such as 'open access', 'institutional repository' and 'academic journals' were identified, and topics to be continuously researched were identified.

자연언어 질의문에서 추출된 키워드들은 정답추출에 미치는 비중이 다른 경우가 많지만 키워드들에 대해 상대적인 가중치를 부여하기가 어렵다. 본 논문에서는 이러한 문제점을 해결하기 위하여 질의 문장의 구문 정보를 이용하여 중심키워드와 일반키워드들로 구분하였으며 이를 기반으로 키워드들 간의 가중치 부여 방법을 제안한다. 질의문 코퍼스로부터 질문 유형을 분석하여 구문을 추출하고 추출된 구문정보를 이용하여 질의문에서 키워드들을 추출한다. 이렇게 얻어진 키워드들을 이용하여 다량의 문서들 속에서 중심키워드와 일반키워드들 간의 불린 검색을 통해 질의문의 정답이 포함되었을 가능성이 큰 단락을 추출하고, 질의문과 추출된 단락간의 유사도 측정을 통해 단락을 순위화 한다. 본 논문에서 제안하는 시스템은 질의문의 정답이 포함된 단락추출에 대한 정확도를 향상시킬 것으로 기대된다.

This paper identifies core research topics and their relationships by deriving the research topic networks in the technology management field using co-word analysis. Contrary to the conventional approach in which undirected networks are constructed based on normalized co-occurrence frequency, this study analyzes directed networks of keywords by employing the confidence index of association rule mining for pairs of keywords. Author keywords included in 2,456 articles published in nine international journals of technology management in 2011~2014 are extracted and categorized into three types: THEME, METHOD, and FIELD. One-mode networks for each type of keywords are constructed to identify core research keywords and their interrelationships with each type. We then derive the two-mode networks composed of different two types of keywords, THEME-METHOD and THEME-FIELD, to explore which methods or fields are frequently employed or studied for each theme. The findings of this study are expected to be fruitfully referred for researchers in the field of technology management to grasp research trends and set the future research directions.

The purpose of this study was to identify the characteristics of the contents included in the curriculum and 382 syllabi of the department of home economics education of College of Education in Korea and analyze the correlation by detailed area through the keyword network method. In order to analyze the home economics education curriculum and 382 syllabuses of a total of 11 universities, the frequency of keyword occurrence was analyzed using the KrKwic program, also the degree of connection between keywords and various centrality scales were calculated and visualized. The results of this study were as follows. First, as a result of analyzing the entire syllabi, keywords representing various fields such as family, secondary school, clothing, food, consumer, and design appeared evenly, and keywords related to teaching methods such as 'method', 'practice', 'change', and 'principle' were appeared. Those keywords showed high degree of connection and centrality. Second, in the detailed sectoral analysis, core keywords for each area appeared, and each subject were found to reflect the core keywords of the academic base. This study contributes to the conversion of curriculum of the department of home economics education to future-oriented and convergent curriculum.

Knowledge management can be defined as the valuable storing and creation of new knowledge, as well as the sharing of this knowledge to be applied in all areas of an organization's management activities (Turban et al., 2003). In a knowledge-based society where intangible intellectual assets are the source of competitive advantage rather than tangible assets, knowledge management activities are emphasized in both academia and industry. This study analyzes research on "knowledge management" keyword indexed in the Korean Citation Index (https://kci.go.kr), operated by the National Research Foundation of Korea (NRF), to identify related research trends in Korea and suggest future directions for knowledge management activities. The results show that knowledge management is being researched through the integration of various fields and theories, indicating the potential for expanding research topics and fostering interdisciplinary collaboration. Furthermore, the study of knowledge management often include the keyword 'innovation', emphasizing its significant role in organizational and technological innovations. The analysis of keywords by year also reveals that they reflect the major environmental changes of each period, demonstrating the increasing importance of knowledge management in the era of the Fourth Industrial Revolution.

최근 '미투운동'이 활발히 진행되면서 새로운 페미니즘의 물결을 맞이하였다. 이전의 페미니즘 운동과의 차이점은 SNS 를 통해 익명으로 활동하며 전파속도가 굉장히 빠르다는 것이다. 본 연구는 미투운동의 이러한 특성을 고려하여 실제 트위터 데이터에서 주요 키워드를 파악하고, 해당 키워드의 연관성 및 네트워크 분석으로 사회적 맥락을 알아본다.

The purpose of this preliminary study is to collect specific examples of book reports and understand semantic characteristics of them through semantic network. The analysis was conducted with 23 book reports which classified by three groups. The keywords were selected from the of book reports. Five types of keyword network were composed based on co-occurrence relations with keywords. The result of this study is following these. First, each keyword network of book reports of groups and individuals is shown to have different structural characteristics. Second, each network has different high centrality keywords according to the result analysis of 3 types of centrality(degree centrality, closeness centrality, betweenness centrality). These characteristic means that keyword network analysis is useful in recognizing the characteristics of not only groups' and but also individual's book reports.
