Reciprocal nature of social capital in Facebook: An analysis of tagging activity
Taehyun Ha, Seunghee Han, Sangwon Lee, Jang Hyun Kim
Online Information Review 41(6)
This study mainly aims to investigate how we can understand social media interactions better by explicating the process of social capital formation on Facebook from a reciprocity perspective. Design/methodology/approach This study observed users who got tagged on Facebook by his/her friends and how s/he responded to that tagging activity. 4,666 posts and 418,580 comments from The New York Times Facebook page were collected for the observation. Findings A majority (77.87%) of users who were tagged by their friends showed reactions to their tagging. In detail, 33.63%, 44.20%, and 0.04% of users responded by comments, “Likes”, and “Shares”, respectively. 90.11% of the comments and 98.58% of the “Likes” were expressed on a comment or sub-comment, and only 9.89% of the comments and 1.42% of the “Likes” were expressed on a post. This indicates that a high percentage of users respond to their tagging notification, and they prefer dialogic responses to non-dialogic responses. Originality/value Previous studies have focused on photo tagging activity in social media, but user tagging activity had not been studied enough. This study examines the effects of Facebook tagging activity from a reciprocal perspective.
Understanding nomophobia: Structural equation modeling and semantic network analysis of smartphone separation anxiety
Seunghee Han, Ki Joon Kim, Jang Hyun Kim
Cyberpsychology, Behavior, and Social Networking 20(7)
This study explicates nomophobia by developing a research model that identifies several determinants of smartphone separation anxiety and by conducting semantic network analyses on smartphone users' verbal descriptions of the meaning of their smartphones. Structural equation modeling of the proposed model indicates that personal memories evoked by smartphones encourage users to extend their identity onto their devices. When users perceive smartphones as their extended selves, they are more likely to get attached to the devices, which, in turn, leads to nomophobia by heightening the phone proximity-seeking tendency. This finding is also supplemented by the results of the semantic network analyses revealing that the words related to memory, self, and proximity-seeking are indeed more frequently used in the high, compared with low, nomophobia group.
Intra-industry Innovation, Spillovers, and Industry Evolution: Evidence from the Korean ICT Industry

Telematics and Informatics 34(8)
Companies innovate themselves to survive competition, and successful innovations are transferred to the industry as a whole through imitation. In this paper, the technical efficiency (TE) of the Korean information and communication technology (ICT) industry is estimated through stochastic frontier analysis, and the efficiencies from 2000 to 2013 are compared through meta-frontier analysis. In addition, by analyzing the effect of innovations that move the production function up on the TE and the meta-frontier efficiency through the two-stage least square model, this paper investigates the effects of innovation on other companies in the industry in the short- and long-term and how the industry evolves accordingly. As a result, sudden inflation of the meta-technology ratio caused by a few innovative firms automatically lowers the average TE. However, the innovation spills over intra-industry by the efforts of other firms trying to reach around the innovation (i.e., imitation). This recovers other firms’ TE and increases meta-frontier efficiency. In addition, this paper provides theoretical and practical implications of the results.
Examining user perceptions of smartwatch through dynamic topic modeling

Telematics and Informatics
Since the 2010s, various companies have begun to manufacture wearable smartwatch devices, but the current sales of these products are not impressive. This study investigates how the limitations of the smartwatch are related to perceptual discomforts. Theoretically, this study evaluates the claim that the discomfort that users appear to have with the smartwatch stem from failed remediation. Users perceive the smartwatch more as a set of functional sensors rather than a watch or smartphone. Specifically, from the remediation perspective, the authors asked how users perceive the functions of the smartwatch. This study used dynamic topic modeling for topics on the smartwatch on Reddit. This study reports that the smartwatch has failed to provide a proper way to use the remediated content that it provides. Suggestions for future studies are addressed.
The innovation of the internet: a semantic network analysis of the Internet of Things

Telematics and Informatics
The internet is evolving toward internet of everything. This study tracks the trends of academic research on Internet of Things (IoT) by examining Web of Science database using semantic network analysis. Although past studies provided a lot of insights on technological aspects of IoT, they have failed to investigate technological acceptance of the technology in academia, industry, and government. As the first step of such an analysis, this study analysed academia perception of IoT using the analysis of words frequency, co-occurrence, and distance. Many clusters were identified from the semantic network of 2017–2015 including smart home and smart grid, sensor networking, physical networking, environmental monitoring and security, and cloud computing and big data. Suggestions for future studies are addressed.
Analysis on the evolution and innovation of online game industry using meta-frontier analysis
Daeho Lee, Sangwon Lee, Jang Hyun Kim
Asian Journal of Technology Innovation
The game industry has made great progress in the recent decade, and recently other layers in the information and communication technology ecosystem affect the innovation and evolution of the game industry with the emergence of the Internet and online games. This paper estimates the changes in efficiency by data envelopment analysis and meta-frontier analysis in order to investigate how the online game industry evolves. As a result, there were enterprises that lifted up the production function of the game industry by innovation when the external factors such as diffusion of the broadband Internet network and mobile Internet environment affected the game industry. The result implies that the steady increment of meta-frontier efficiency means that the industry is growing by innovation or imitation, or both.
Better innovation, better future: working together for innovating Asia
Kong-rae Lee, Jin Chen, Jizhen Li, Jang Hyun Kim
Asian Journal of Technology Innovation 25(1)
This special issue of Asian Journal of Technology Innovation aims at contributing to academic collaborations and exchanges of scholars in Asia including CICALICS and ASIALICS members. By introducing 12 research articles, this special issue discloses how firms, individuals, and nations are striving to catch up with other advanced entities, enlarge their excellence over competitors, and cooperate among university-government-industry (triple helix) sectors. Strength of research in innovation studies lie in theoretical accounts of innovation, lively cases from the innovation’s real world, and systematic approaches to innovations.
