In this study, we examined the motivations of using Kakaotalk's gift that is one of services provided by Kakaotalk, the most popular mobile-based messenger. We also investigated possible effects of these motivations on the satisfaction of the Kakaotalk's service and a potential association of these motivations with the frequency of purchasing gifts using the service. In order to answer the research questions, we conducted a survey that recruited 220 users ranging from teenagers to in forties. As the main results of analysis, we identified four different types of user's motivations for Kakaotalk's gift: beneficial motivation, convenient motivation, improvised buying motivation, and entertaining motivation. Both the beneficial motivation and the entertaining motivation were significantly associated with the gratification of using Kakaotalk's gift, which was in turn significantly associated with the frequency of purchasing gifts through the service.

The spread of smartphones enabled the two-way communication through the Internet, and character emoticons added fun and comfort to communication among users. To figure out laughter-arousing factors, a survey about emoticon designs of Kakaotalk Itemstore was conducted, targeting university students in their twenties. An interaction of 'user-preferred emoticons' and 'laughter-arousing emoticons' was analyzed. 90% of 'user-preferred emoticons' were 'humorous emoticons', and 84% of respondents answered that there is a relationship between 'user-preferred emoticons' and 'laughter-arousing emoticons'. Consequently, a high interaction between the 'rank of emoticons' and 'laughter-arousing emoticons' was derived. Also, factors of laughter-arousing emoticons were analyzed by studying the ranks of emoticon from 1st to 8th of Kakaotalk Itemstore. Two-divisional figures reminding pure kids, maximization of emotional expression by omission or exaggeration of mouth, and smoothness by concave curves aroused laughter. Intuitively understandable gestures were employed in terms of action. Furthermore, two-divisional figures' acting with comparably small body, hands and foot to their head, and people-mimicking motions of animals with cuteness and familiarity enabled arousal of laughter. In facial expressions, humorous articulation of sad, busy or mad expression enabled positive communion among users.

최근 제품을 주문하거나 상품을 조회하는 등의 간단한 상담을 챗봇을 이용하여 자동화하는 온라인 쇼핑몰들이 늘어나고 있다. 이는 고객을 상담하는 상담원의 업무를 줄여줄 뿐 아니라 고객 상담을 즉각적이고 효율적으로 진행할 수 있다. 또한 사용자의 입장에서 챗봇은 처음 이용하는 사람도 사용하기가 쉽고, 상담원과의 연결까지 기다리지 않고 사용자가 원하는 시간에 커뮤니케이션이 가능하고, 기업 측면에서는 인건비가 감소되고 고객관리가 용이해진다는 장점이 있다. 그러나 챗봇은 주어진 질문에만 대답할 수 있고, 처음 메뉴를 파악하기 힘들다는 단점이 있다. 따라서 본 논문에서는 카카오톡 오픈빌더를 사용하여 질문의도를 파악하는 intent와 entity를 추출한 뒤 딥러닝을 통해 체계적으로 학습을 진행한다. 이를 통해 주어지지 않은 질문들을 파악한다. 또한, 오픈빌더의 시나리오 선택 기능을 활용하여 초기에 선택할 수 있는 메뉴를 파악하기 쉽도록 구현하였다. 사용자는 본 논문에서 제안하는 챗봇을 통해 사용자는 상담에 필요한 도움을 받을 수 있을 것으로 기대된다.

Given the prevalence of mobile social network services (SNS) such as Facebook and Kakaotalk, it has become important to understand user's continuance behavior in a mobile SNS environment. Although trust and privacy concerns play a key role in SNS users' decision-making processes, most studies on SNS have shed little light on the effects of trust and privacy concerns on SNS continuance intention. In this regard, this paper developed an integrated model to deeply understand the key antecedents of user's continuance intention to use mobile SNS by incorporating trust and privacy concerns into extended expectation-confirmation model. The proposed research model was tested by using survey data collected from 170 users who have experience with Kakaotalk. The findings of this study found that the proposed theoretical framework provides a statistically significant explanation of the variance in continuance intention of mobile SNS. The analysis results indicate that trust serves as the salient antecedent of continuance intention to use mobile SNS. However, it was found that privacy concerns negatively influence trust, whereas it is not significantly related to continuance intention of mobile SNS. The theoretical and practical implications of the findings were described.

Mobile messenger services (MMSs), such as Kakaotalk, Wetalk, Line, and Whatsapp, are gaining popularity worldwide because of communicating with other people without any cost. We examined key antecedents of user loyalty to understand user's decision-making process in the MMS environment. To capture a long-term relationship with service providers, we posit relational commitment and user satisfaction as key predictors of user loyalty. Moreover, the effects of perceived usefulness, perceived enjoyment, and corporate image on user's decision-making processes were examined. The proposed model was tested by applying partial least squares to data from 220 experienced Kakaotalk users. The findings of this study found that both relational commitment and user satisfaction play an important role in enhancing user loyalty in the MMS context. The analysis results indicate that corporate image influences relational commitment and user loyalty through user satisfaction. The analysis results help MMS providers establish management or marketing strategies to effectively improve user loyalty.
