Big data analytics and social media have shifted the way fashion trends are dictated. Fashion as a medium for expressing gender has created new concepts of masculinity in popular culture, where men are increasingly depicted in a softer style. In this study, we analyzed 2,879 menswear collections over a 10-year period from Vogue US to uncover key menswear trends. Using Semantic Network Analysis (SNA) on Orange3, we were able to quantitatively analyze how contemporary menswear designers interpreted diversified trends of masculinity on the runway. Frequency and degree centrality were measured to weigh the significance of trend keywords. "Jacket (f = 3056; DC = 0.80), shirt (f = 1912; DC = 0.60) and pant (f = 1618; DC = 0.53)" were among the most prominent keywords. Our results showed that soft masculine keywords, e.g., "lace, floral, and pink" also appeared, but with the majority scoring DC = < 0.10. The findings provide an insight into key menswear trends through frequency, degree centrality measurements, time-series analysis, egocentric, and visual semantic networks. This also demonstrates the feasibility of using text analytics to visualize design trends, concepts, and patterns for application as an ideation tool for academic researchers, designers, and fashion retailers.

This study aims to investigate how pre-service elementary school teachers understand 'something scientific', 'being scientific', 'scientific events' and 'scientific questions' through semantic network analysis. To achieve this purpose, this study carried out a central analysis of the frequency and density of words and the degree of connection between key words, a concentric analysis, a click analysis and a common network analysis through text semantic network analysis by using NetMiner 4.0 Program. Based on the results of these analyses, this study came to the following conclusions. Firstly, in perceiving 'something scientific', pre-service elementary school teachers recognized 'verification', 'objective' and 'experiment' as most important words. In other words, they perceived that main grounds for something scientific should be provided through clear facts, possible to be verified and accompanied by an exact and logical theoretical system. In regard to 'being scientific', they perceived 'explanation', 'objective' and 'verification' as most important words, while having a traditional point of view that science is a set that can be explained objectively. Secondly, in regard that the term, 'observation', is contained in 'scientific events', they showed a high rate of understanding it as a scientific event. In regard to scientifical reasons, they showed the highest frequency of 'observation', and for unscientific reasons, they showed the highest frequency of 'behavior'. In perceiving 'scientific questions', they showed the highest frequency of determining bacteria-related questions as scientific. As a reason why they thought as scientific, they mentioned 'observation' most frequently like 'scientific events', while mentioning 'value judgement' as a reason why they thought as unscientific most frequently. From the results of integrated network analysis, this study found out that words pre-service teachers commonly used in stating scientific events or scientific questions were overlapped with words they mentioned for scientific events or scientific questions. As a result, it was found there were many pre-service teachers having interpreted scientific words without clearly distinguishing scientific events or scientific questions.

컴퓨터비전에서 가장 기본적이고, 복잡한 문제를 수반하는 의미론적 분할(Semantic segmentation)은 이미지의 각 픽셀을 특정 객체로 분류하며, 레이블(label)을 지정하는 작업을 수행한다. 기존에 연구되어온 확률적 그래프 모델인 MRF와 CRF는 픽셀 수준의 라벨링 작업의 정확도를 높이는 효과적인 방법으로 연구되어왔다. 본 논문에서는 최근 각광받고 있는 딥러닝의 한 부류인 CNN과 확률 모델인 CRF를 결합한 형태의 의미론적 분할 방법을 제안하였다. 학습과 성능 검증을 위하여 Pascal VOC 2012 이미지 데이터베이스를 사용하였고, 학습에 사용되지 않은 임의의 이미지를 이용하여 테스트를 진행 하였다. 연구의 결과로서 기존 의미론적 분할 알고리즘보다 더욱 뛰어난 분할 성능을 보여주었다.

이번 연구는 지상파 TV, 중앙일간지, 지역지, 등 총 37개의 보도 매체의 2019년 강원도 대형 화재 보도를 분석하여 미디어의제를 파악하고 매체별, 시기별 미디어의제를 비교, 분석하였다. 토픽모델링 알고리즘과 의미망 분석을 활용한 연구는 네트워크 미디어의제의 구성을 분석하고 QAP 상관분석을 활용하여 매체간 의제 설정 효과도 검증하였다. 분석 결과, 2019년 강원도 화재 보도에서는 이재민 지원과 정치권 갈등 속성을 중심으로 다소 선정적인 미디어의제가 형성되었고 시기별, 매체별 미디어의제 간 유사성이 높은 것으로 나타났다. 이번 연구는 네트워크 의제설정 모델을 토대로 의미망 분석 도구를 활용해 대량의 기사를 분석하면서 기존의 빈도분석과는 구별되는 조사방법론을 구현한 연구라는 점에서 또 하나의 의미를 가질 수 있다.

This study applied network agenda-setting theory to analyze the impact of the agenda-setting function of the media on certain issues by focusing on the agenda at the center of controversy, 'Creative Economy'. To this end, the study extracted the data referred to creative economy in the media and SNS from 1 January 2008 to 31 December 2014, and analyzed the data using the network analysis program UCINET and the Korean language analysis program Textom. The results of the present study show that, during the period under former President Lee (2008-2011), the media's creative economy agenda-setting function did not exert a significant impact on the agenda-setting within SNS. However, from 2012 when the government of former President Park Geun-hye had started, the agenda-setting function of the media starts to show increasingly strong influence on the agenda cognition in SNS. The central words and sub-words configuration forming the center of the semantic network moved in the direction of a high correlation, in addition to the gradually increasing correlation based on QAP correlation analysis. In 2014, the semantic networks of the media and SNS bore a close resemblance to each other, while the shape of networks and sub-words structure also had a high level of similarity.

This study investigated the semantic network based on the focus of the fashion image and SNS text utilized by global SPA brands on the last seven years in terms of the quantity and quality of data generated by the fast-changing fashion trends and fashion content-based media environment. The research method relocated frequency, density and repetitive key words as well as visualized algorithms using the UCINET 6.347 program and the overall classification of the text related to fashion images on social networks used by global SPA brands. The conclusions of the study are as follows. A common aspect of global SPA brands is that by looking at the basis of text extraction on SNS, exposure through image of products is considered important for sales. The following is a discriminatory aspect of global SPA brands. First, ZARA consistently exposes marketing using a variety of professions and nationalities to SNS. Second, UNIQLO's correlation exposes its collaboration promotion to SNS while steadily exposing basic items. Third, in the case of H&M, some discriminatory results were found with other brands in connectivity with each cluster category that showed remarkably independent results.

본 논문에서는 의미 네트워크에 기반을 둔 지식베이스를 이용하여 단어 의미의 모호성을 해소하는 방법들을 소개 한다. 기본이 되는 방법은 입력문자의 의미해석이 진행됨에 따라 수집되는 지식베이스내의 경로(path)들을 추적하여 이용하는 것이다. 이러한 경로들을 의미경로(semantic path)라고 부른다. 파싱과정에서 한 단어가 입력되면 이단어가 가질수 있는 의미 중에서 어느 의미 경로에도 이용되지 않은 것들이 제거된다. 각 제거는 의미 경로들을 통하여 전파되어 이미 입력된 다른 단어들의 의미의 제거를 유발한다. 이 박업은 더이상 제거되는 의미가 없을때 까지 반복 진행된느데 이를 recursive word sense removal 작업이라 부른다. 추상적인 개념의 구체화(conctetion) 작업도 단어 의미 모호성해소의 중요한 방법인데, 본 논문에서는 이를 경로조절작업(path adjustment operation)이라고 불리는 방법을 이용하여 확장시키는 방법을 소개한다. 의미사이의 연과성(semantic association)이나 구문분석으로부터의 정보를 위의 방법들과 관련지어 이용하는 방법도 살펴본다.

This article presents an examination of the major cognitive-semantic theories in linguistics (Langacker, Lakoff, Fillmore, Croft). The CST's foundations are discussed concerning the educational policy changes, which are necessary to improve the linguistic disciplines in the changing context of higher education, as well as the empowerment and development of the industry. It is relevant in the light of the linguistic specialists' quality training and the development of effective methods of language learning. Consideration of the theories content, tools, and methods of language teaching, which are an important component of quality teaching and the formation of a set of knowledge and skills of students of linguistic specialties, remains crucial. This study aims to establish the main theoretical positions and directions of cognitive-semantic theory in linguistics, determine the usefulness of teaching the basics of cognitive linguistics, the feasibility of using methods of cognitive-semantic nature in the learning process. During the research, the methods of linguistic description and observation, analysis, and synthesis were applied. The result of the study is to establish the need to study basic linguistic theories, as well as general theoretical precepts of cognitive linguistics, which remains one of the effective directions in the postmodern mainstream. It also clarifies the place of the main cognitive-semantic theories in the teaching linguistics' practice of the XXI century.
