질의 응답 시스템은 사용자의 질의를 분석하여 제한된 길이의 정답을 제시해 주는 시스템이다. 질의 응답 시스템은 정확한 정답을 추출하기 위해 사용자의 질의를 분석하는 과정을 필요로 한다. 본 논문에서는 초점단어(focus-word)를 이용한 질의분석을 제안한다. 초점단어란 정답유형을 결정하는데 단서가 되는 단어로써, 추출된 초점단어에 의해 75개의 하위정답유형 중 하나가 결정된다. 실험에는 학습 데이터의 일부와 일반 Web에서 수집한 테스트 데이터가 사용되었다. 실험결과 상위범주는 97.18%, 하위범주는 95.31%의 정확도를 보였다.

현 청소년들의 학교내 생활환경에서 문제점으로 대두되는 폭력 및 자살사고 발생률 증가에 대한 예방차원의 빅 데이터 처리 분석 시스템을 목표로 연구하였고 설계의 경제성과 용이성, 적용의 신속성 등을 고려해서 많은 이용률을 가지고 있는 오픈 소스인, 하둡 시스템(Hadoop system)의 맵리듀스(MapReduce) 알고리즘과 분산 병렬 환경을 위한 HDFS(Hadoop Distibuted File System) 구성을 사용하여 실험하였다. 연구에서 사용된 분석기법은 기존의 통계적인 분석기법들이 가지는 난이도를 피하기 위해 상업적인 사회 망의 비정형 대화 자료를 이용해서 폭력성 어휘에 대한 단어 수(word count) 분석을 적용하여 폭행, 자살사고를 사전에 감지하여 예방하는 감성분석(sentiment analysis) 시스템을 텍스트 마이닝 관점에서 제안하여 실험하였다.

Purpose - This study investigates research trends by searching for English keywords and abstracts in 1,511 Korean journal articles in the Korea Citation Index from the 2002-2019 period using the term "Port." The study aims to lay the foundation for a more balanced development of port research. Design/methodology - Using abstract and keyword data, we perform frequency analysis and word embedding (Word2vec). A t-SNE plot shows the main keywords extracted using the TextRank algorithm. To analyze which words were used in what context in our two nine-year subperiods (2002-2010 and 2010-2019), we use Scattertext and scaled F-scores. Findings - First, during the 18-year study period, port research has developed through the convergence of diverse academic fields, covering 102 subject areas and 219 journals. Second, our frequency analysis of 4,431 keywords in 1,511 papers shows that the words "Port" (60 times), "Port Competitiveness" (33 times), and "Port Authority" (29 times), among others, are attractive to most researchers. Third, a word embedding analysis identifies the words highly correlated with the top eight keywords and visually shows four different subject clusters in a t-SNE plot. Fourth, we use Scattertext to compare words used in the two research sub-periods. Originality/value - This study is the first to apply abstract and keyword analysis and various text mining techniques to Korean journal articles in port research and thus has important implications. Further in-depth studies should collect a greater variety of textual data and analyze and compare port studies from different countries.

단어 의미 유사도 측정은 정보 검색이나 문서 분류와 같이 자연어 처리 분야 문제를 해결하는 데 큰 도움을 준다. 이러한 의미 유사도 측정 문제를 해결하기 위하여 단어의 계층 구조를 사용한 기존 연구들이 있지만 이는 단어의 의미를 고려하고 있지 않아 만족스럽지 못한 결과를 보여주고 있다. 본 논문에서는 국립국어원에서 간행한 표준국어대사전에 50만 어휘가 추가된 우리말샘 사전을 기반으로 하여 한국어 단어에 대한 계층 구조를 파악했다. 그리고 단어의 용례를 word2vec 모델에 학습하여 단어의 문맥적 의미를 파악하고, 단어의 정의문을 sent2vec 모델에 학습하여 단어의 사전적 의미를 파악했다. 또한, 구축된 계층 구조와 학습된 word2vec, sent2vec 모델을 이용하여 한국어 단어 의미 유사도를 측정하는 모델을 제안했다. 마지막으로 성능 평가를 통해 제안하는 모델이 기존 모델보다 향상된 성능을 보임을 입증했다.

The purpose of this study was to compare the factors affecting mother's satisfaction, word-of-mouth, and repurchase intention for the complete collection and monography picture books. Questionnaires from 323 5-year-olds' mothers in Seoul and Kyunggi province were analysed. The findings are as follows. Firstly, mother's product involvement and dual readership, and child's preference for picture books were common effective factors to improve mother's satisfaction, word-of-mouth, and repurchase intention. Secondly, reflection of child's opinions explained mother's satisfaction, word-of-mouth, and repurchase intention only for the monography, not for the complete collection. Thirdly, mother's product involvement had a direct effect on the repurchase intention of monography, while mother's subjective knowledge was more important for the repurchase intention of the complete collection.

In the highly competitive world, there has been a concomitant increase in the need for the research and planning methodology, which can perform an advanced assessment of technological opportunities and an early Perception of threats and possibilities of the emerging technology according to the nation's economic and social status. This research is aiming to provide indicators and visualization methods to measure the latest research trend and aspect underlying scientific and technological documents to researchers and policy planners using 'Co-word Analysis' Organic light emitting diodes(OLED) is an emerging technology in various fields of display and which has a highly prospective market value. In this paper, we presented an analysis on OLED. Co-word analysis was employed to reveal patterns and trends in the OLED fields by measuring the association strength of terms representatives of relevant publications or other texts produced in the OLED field. Data were collected from SCI and the critical keywords could De extracted from the author keywords. These extracted keywords were further standardized.

Purpose - This study aims to examine the influence of social network service (SNS) on the brand image of infant food products; highlight the effects of brand image on the purchasing and word-of-mouth intention; and explore the effects of the purchasing intention on the word-of-mouth intention. Research design, data, and methodology - Based on previous studies, it was found that the fundamental SNS characteristics for infant food products are reliability, interactivity, and informative. Using AMOS 22.0 and structural equation modeling (SEM), 288 questionnaires were surveyed as a statistical method for examining the proposed hypotheses. Results - The analysis shows that reliability and informative have significant impacts on brand image, whereas interactivity does not. Again, the effect of brand image of infant food products on the purchase and word-of-mouth intention is statistically significant. However, the results differ across the "working housewife" and the "full-time housewife" groups. The connection between reliability and brand image was found to be statistically significant in this study. Conclusions - This study analyzes the effects of SNS characteristics on the brand image of infant food products and the effect of the brand image on purchase and word-of-mouth intentions, and provides practical implications for the same.
