많은 사용자들이 자신의 일상과 활동을 사회연결망서비스(SNS)에 업로드하고 있으며 자신들의 포스팅을 설명하기 위한 Hashtag를 사용하고 있다. Hashtag는 사용자가 스스로 자신의 포스팅에 대한 카테고리를 지정한다는 장점이 있으나 최근까지도 사용자가 직접 수동적으로 입력해야 한다는 번거로움이 있었다. 이에 본 연구에서는 이러한 문제를 개선하기 위하여 SNS 상에서 사용자가 업로드하는 이미지를 기반으로 하여 적절한 Hashtag를 추천하는 방법을 제안하였다. 본 연구를 위하여 촬영정보에 기반한 분석, 주소에 기반한 분석, 타사용자에 기반한 분석, 이미지 자체에 기반한 분석 방법을 설계 및 구현하였다. 또한 제안 방법이 기존의 시스템에 비해 개선되었는지 확인하기 위하여 성능 테스트를 실시하였으며 15개국 212명의 SNS 사용자를 대상으로 평가를 진행하였다. 분석 결과 기존에 서비스되는 Hashtag 추천 시스템에 비해 제안된 시스템이 높은 정확도의 추천 결과를 보였으며 기존 대비 개선되었다는 것을 확인할 수 있었다.

This study explores the effect of hashtag type on consumer response via evaluations of SNS fashion influencer and information in the context of fashion product communication. The moderating effect of perceived fit between hashtag content and fashion product image on information evaluation was also investigated. An online survey was conducted, and responses from 152 Instagram users were collected. The results indicated that hashtag type (informative vs storytelling) affects the evaluations of influencer and information. First, the informative hashtag has a positive effect on influencer's expertise and usefulness of information. Meanwhile, storytelling type has a positive effect on the familiarity of the influencer. This study also verified the mediated paths from hashtag type to consumer response through the evaluations of SNS fashion influencer and information. The influencer's expertise and familiarity mediated the effect of hashtag type on consumer response. In the information evaluation, only the mediating effect of usefulness was significant. Finally, the high condition of the perceived fit between hashtag content and fashion product image was found to highly evaluate the trust of information. This study extends the scope of fashion communication research from various angles by examining the role of the hashtag as a new type of information source.

The mobile social networking application Instagram is a well-known platform for sharing photos and videos. Since it is folksonomy-oriented, it provides the possibility for image indexing and knowledge representation through the assignment of hashtags to posted content. The purpose of this study is to analyze how Instagram users tag their pictures regarding different kinds of picture and hashtag categories. For such a content analysis, a distinction is made between Food, Pets, Selfies, Friends, Activity, Art, Fashion, Quotes (captioned photos), Landscape, and Architecture image categories as well as Content-relatedness (ofness, aboutness, and iconology), Emotiveness, Isness, Performativeness, Fakeness, "Insta"-Tags, and Sentences as hashtag categories. Altogether, 14,649 hashtags of 1,000 Instagram images were intellectually analyzed (100 pictures for each image category). Research questions are stated as follows: RQ1: Are there any differences in relative frequencies of hashtags in the picture categories? On average the number of hashtags per picture is 15. Lowest average values received the categories Selfie (average 10.9 tags per picture) and Friends (average 11.7 tags per picture); for highest, the categories Pet (average 18.6 tags), Fashion (average 17.6 tags), and Landscape (average 16.8 tags). RQ2: Given a picture category, what is the distribution of hashtag categories; and given a hashtag category, what is the distribution of picture categories? 60.20% of all hashtags were classified into the category Content-relatedness. Categories Emotiveness (about 4.38%) and Sentences (0.99%) were less often frequent. RQ3: Is there any association between image categories and hashtag categories? A statistically significant association between hashtag categories and image categories on Instagram exists, as a chi-square test of independence shows. This study enables a first broad overview on the tagging behavior of Instagram users and is not limited to a specific hashtag or picture motive, like previous studies.

일반 사용자들이 특정 주제에 관한 짧은 바이럴 동영상을 모방·제작·공유하는 해시태그 챌린지는 숏폼 비디오 플랫폼의 흥미로운 사회 현상 중 하나로 단연 손꼽힌다. 그러나 해시태그 챌린지의 인기가 높아지고 있음에도 불구하고, 관련 사용자 행동에 대한 이론적 논의는 여전히 매우 부족하다. 본 연구는 해시태그 챌린지에 대한 사용자의 참여 의도를 보다 정확히 이해하기 위해서 마이크로 인플루언서의 영향을 관심있게 살펴보고자 하였다. 이를 위해 준사회적 상호작용 이론과 모방 행동 문헌을 주요 이론적 근거로 활용하였다. TikTok 사용자를 대상으로 한 243개 설문조사 데이터를 분석한 결과, 본 연구는 사용자가 마이크로 인플루언서와 친밀감을 느끼는 환상(즉, 준사회적 상호작용)이 해시태그 챌린지에 대한 유저의 참여 의도에 상당한 긍정적인 영향을 미친다는 것을 알 수 있었다. 또한, 숏폼 비디오 플랫폼에서 준사회적 상호작용의 정도는 크게 미디어 콘텐츠 관련 요소와 미디어 캐릭터 관련 요소(콘텐츠 매력도, 신체적 매력도, 태도 유사성)에 의해 결정된다는 것을 알 수 있었다. 본 연구는 숏폼 비디오 플랫폼에서 마이크로 인플루언서의 활용 효과를 높이기 위한 방법에 관한 이론적·실무적 시사점을 제공한다.

해시태그는 현재 페이스북, 트위터와 같은 SNS와 개인 블로그 등에서 활발하게 사용되고 있다. 하지만 스팸성 목적 또는 게시글 조회수 증가 등의 목적으로 무분별하게 해시태그를 사용하여 태그검색의 효율성이 떨어지고 있다. 이에 따라 본 논문에서는 태그검색의 정확도를 높이고자 기존의 키워드 추출 알고리즘과 단어간 유사도 평가 알고리즘을 이용한 태그 검색 시스템을 제안하였다. 제안하는 시스템의 테스트 결과 태그 검색의 정확도가 향상됨을 알 수 있었다.

Hashtags (#) have received a great deal of attention from academia and industry as an effective digital tool for engaging social media users and facilitating electronic word-of-mouth for brands. We delved into motivations concerning people's brand-related hashtag-posting behavior on social media. The findings revealed three motivations for posting brand-related hashtags on social media: social acceptance, brand altruism, and incentive seeking. Additionally, we examined the relationships between motivations and brand relationship variables. The results showed that social acceptance and brand-related altruism predicted all of the five relationship variables (i.e., brand attitude, brand trust, brand affective and calculative commitment and brand loyalty), while incentive-seeking predicted brand calculative commitment and brand loyalty. The findings of the study provide some meaningful insights into the development of brand communication strategies and help marketers capitalize on social media platforms to achieve higher user involvement.

Social media has emerged as a major hub of engagement between brands and consumers in recent years, and allows user-generated content to serve as a powerful means of encouraging communication between the sides. However, it is challenging to negotiate user-generated content owing to its lack of structure and the enormous amount generated. This study focuses on the hashtag, a metadata tag that reflects customers' brand perception through social media platforms. Online users share their knowledge and impressions using a wide variety of hashtags. We examine hashtags that co-occur with particular branded hashtags on the social media platform, Instagram, to derive insights about brand perception. We apply text mining technology and network analysis to identify the perceptions of brand images among consumers on the site, where this helps distinguish among the diverse personalities of the brands. This study contributes to highlighting the value of hashtags in constructing brand personality in the context of online marketing.

트위터는 사용자들이 140개 정도의 문자들로 이루어진 짧은 메시지를 웹에 포스팅 할 수 있도록 제공하는 인기 있는 소셜 미디어 플랫폼이다. 해시태그는 이러한 트위터 사용자들이 특정한 주제에 대해서 토론을 하거나 높은 트랜딩을 가지는 이슈를 나타내고자 할 때 사용하는 특정한 단어나 두음문자이다. 하지만 동일한 해시태그를 포함하는 포스트들은 관련 있는 문장이 아닌 시간 순서에 의해서 처리되기 때문에, 처음 사용자가 그 해시태그와 관련된 내용을 이해하기 위해서는 다른 불필요한 내용까지 읽어야 하는 어려움이 있다. 본 논문에서는, 이러한 문제점을 해소하기 위한 HBase 기반 자동 요약 시스템을 제안한다. 제안된 시스템은 트위터 API에서 제공하는 스트리밍 데이터를 HBase에 저장한 후 퍼지 시스템과 접목하여 자동 요약 방법을 시행하였다. 이를 통해서 해시태그를 포함한 포스트내의 중복된 내용을 제거하고, 각 포스트들의 중요도를 계산해서 사용자가 트랜딩 토픽내에 관련 있는 주제에 쉽게 접근할 수 있도록 하였다.

This study aims to analyze Instagram hashtags based on big data to investigate changes in consumer trends and perceptions of vegan fashion, and to derive strategies for revitalizing vegan fashion brands based on derived results. Among social media, Instagram was selected as a collection channel, and Instagram hashtags for 'Vegan Fashion' were collected from July 1, 2021 to December 31, 2021. After conducting semantic network analysis with the Ucinet 6 program based on the collected data, the CONCOR analysis on vegan fashion showed the following four clusters: 'Veganism practiced with fashion', 'Bag type of vegan fashion brand', 'Sharing vegan fashion', and 'Diversification of eco-friendly products'. Analysis results showed that the Instagram hashtag for vegan fashion confirmed the MZ generation's increased interest in vegan fashion and their thoughts to recommend and share frequently used items or brand products to people around them. CONCOR analysis of vegan fashion brands showed the following four groups: 'Differentiating the material of vegan bags', 'Eco-friendly products of vegan fashion brands', 'Interest in vegan shoes', and 'Donation campaign of vegan fashion brands'. CONCOR analysis on Meaningout showed the following four clusters: 'MZ Generation's Meaningout Start-up', 'Recommendation Platform for Skin Products', 'Value Consumption Trend for Eco-friendly Clothing', and 'Interest in Eco-friendly Packaging'. The results of this study on vegan fashion, a practical eco-friendly movement that can require changes in social responsibility and perception as issues that directly affect animals, the environment, and humans, are expected to provide basic data to help domestic vegan fashion brands develop marketing strategies.
