Recent advances in digital purchase platforms allow consumer to easy to access online purchase, but the online purchase systems often occurs a negative situations such as service failure. When customer experiences negative service, they want to communicate with the company online chatting service. But not much is known about how customers online chatting service's contextual cues effectiveness. So, the current research seeks to examine the effects of type of online chatting service interface and company market status on customers' perception of service quality and satisfaction with online chatting services. The results of two studies show that, when customer experienced negative online service, they expected to a high status (vs a low status) company had offered better service. but their service request are not met, customers perceive better service quality if served by a low status (vs high status) company represented by a logo (vs. an emoji). These findings will help marketing practitioners strategically how design their chatting service interface according to the their status when they communicate with customer who experienced negative service.

As the competition of 21 cyber universities in Korea has been on a continual increase, they are focusing on improving the quality of the e-learning education in cyber universities. In this study, we intended to derive the failure factors of the previous chatting system in the 2010s and the success factors from previous studies. Next, we identified priorities among five factors(Reliability, UI Convenience, Usability, Network effect, Operational policy) using AHP and the practical ways to implement the chatting service. We applied the chatting system to all the curriculums of S cyber university. Our study finds that the chat service affects the satisfaction of education.

In spoken chatting systems, users'spoken queries are converted to text queries using automatic speech recognition (ASR) engines. If the top-1 results of the ASR engines are incorrect, these errors are propagated to the spoken chatting systems. To improve the top-1 accuracies of ASR engines, we propose a post-processing model to rearrange the top-n outputs of ASR engines using a ranking support vector machine (RankSVM). On the other hand, a number of chatting sentences are needed to train chatting systems. If new chatting sentences are not frequently added to training data, responses of the chatting systems will be old-fashioned soon. To resolve this problem, we propose a data collection model to automatically select chatting sentences from TV and movie scenarios using a support vector machine (SVM). In the experiments, the post-processing model showed a higher precision of 4.4% and a higher recall rate of 6.4% compared to the baseline model (without post-processing). Then, the data collection model showed the high precision of 98.95% and the recall rate of 57.14%.

In order to solve the problems of the information society and the reverse function of chatting, there is a growing need of seeking out approachable educational methods. Therefore, we need to offer that addresses these issues ethical education from elementary school years where the creation of sound personality and its course may be hurt unless otherwise. Yet, there is no detailed curriculum for chatting education which is one of the detailed education areas. Also, how to offer and utilize the chatting education has never been mentioned. Moreover, only reverse function of information-driven changes have been emphasized whereas their desirable functions and information ethical principles have been simply neglected. The paper presents the effectiveness for improvement the school chatting education.

IM(Instant Messenger) chatting service can carry user's various information including life style, geographical position, and psychology & crime history and thus forensic analysis on the IM service is desirable. But, forensic analysis for KakaoTalk's chatting service is not well studied yet. For this reason, we study KakaoTalk's forensic analysis focusing on chatting service. This paper first details a general method of IM forensics investigating the previous articles about IM forensics although there are not many articles. Second, we discuss methodologies for IM forensics wherein we present analysis of table structure and method for reconstruction of chatting message. These result in the basic element of forensic tools of KakaoTalk chatting message. Last, we compare artifacts of KakaoTalk with that of WhatsApp. We conclude that these applications are, at least, different in that table structures and the ways to reconstruct chatting messages are not same and therefore digital evidences or artifacts are not same and somewhat distinct.
