Services based on the IoT technologies have emerged in various business environments. To enhance service quality for convention, maximize experience of attendees and develop sustainable service, this study applies IoT technology for stakeholders of convention.

In this paper, we seek to answer the following research questions: (1) What is the notion of sustainability and smartness in tourism field? (chapter 2-1) (2) What is the customer-driven interaction? (chapter 2-2) (3) What are the appropriate technologies to meet sustainable/smart service and the needs of smart convention and how to apply the technology? (chapter 2-2 and 3) (4) What do stakeholders such as companies and customers gain from sustainable and smart service for smart convention? (chapter 4)

To accomplish the objectives of the study, we took five phases of action research framework. In diagnosing phase, through interviews, observations, and literature studies, there searchers identify current issues and requirements for convention. In action planning phase, through the discussion with the practitioners of the convention, we have selected and arranged services for solving the problems. In action taking phase, smart buttons were installed in the COEX (Interaction convention place), we collected data during the convention period. In evaluation phase, we present the results and value of data. Finally, in specifying learning phase, the researchers summarized the benefits of each stakeholder.

The contribution of this paper is in four ways. First, the notion of sustainability was redefined by including not only socio-cultural, economy and environmental thinking but also the realms of customer-driven! interaction.

Second, this study proposed and constructed a new type of smart service with IoT for smart convention. Third, this research verified that benefits of sustainable and smart service. Finally, this can be used as an example of how conventions can find opportunities using new technologies.

An application of the loT technology based smart button was conducted for convention service, and the development and evaluation results are aligned lo action research framework including diagnosing, action planning, action taking, evaluation, and specifying learning phases. At the first and two phases, various difficulties and problems of the smart convention were diagnosed through interview with practitioners and service models were designed for solving the problems. Mobile service and appropriate IoT technology were discussed and applied to the convention space by installing smart button at the third phase. At the fourth, we derived in the role of Internet of things based mobile technology for smart convention and evaluated results of smart convention service in the various perspective. Finally, we proved value of mobile technology as the omni channel service through data analysis.

Objectives: Chatbot is a program that talks in voice or text. It is equipped with artificial intelligence technology (AI) and is developed in a way to combine with messenger, offering companies new opportunities for business communication. Companies expect cost savings and sales increases by providing chatbot-based services to their customers, such as providing responses to inquiries and fulfilling orders without time constraints. However, the current absence of conversationally perfect AI technology creates a climate in which the public holds unreasonable expectations, as businesses fail to understand the current status of AI and the marketing of chatbot technology companies is hyped.

Methods: This is a single-case study. While looking for a successfully deployed chatbot, we found Naver TalkTalk, a card-based chatbot application. We interviewed Naver’s managerial and technical staff four times and acquired internal data as well as external data.

Results: We illustrate Naver TalkTalk, a successful card-based business chatbot, and examine how Naver TalkTalk has developed and evolved for effective business communication. The first chatbot started without automation and then failed in the process of evolving to automation. This chatbot was changed to cardbot and was re-automated based on the card-based interface and RPA (Robotic Process Automation).

Conclusion: The cardbot-based chatbot is quick and easy to handle, which is why it has been popular among users. It is now becoming a new business communication channel to attract new customers. In addition, the proper automation of business communication is increasing efficiency and reducing costs of businesses.

Using the computer simulation method, we invest19ate the probability distribution of maximum eigenvalue of pair-wise comparison matrix, which has been used as a parameter for measuring the consistency of responses in analytic hierarchy process (AHP). We show that the shape of the distribution of the maximum eigenvalue is different according to the dimension of the matrix. In addition, we cannot find any evidence that the distribution of the Consistency Index is a Normal distribution, which has been claimed in the Previous literature. Accordingly, we suggest using so called K-index calcu1ated based on the concept of cumulative distribution function lather than based on that of arithmetic mean because the probabilistic distribution cannot be assumed to be a Normal distribution. We interpret the simulation results by comparing them with the suggestion of Saaty[11]. Our results show that using Saaty's value could be too generous when the dimension of the matrix is 3 and strict over 4. Finally, we propose new criteria for measuring the response consistency in AHP.

The sales activity of most of small manufacturing companies is based on orders of buyers. The process of promotion, negotiation, receipt and selection of orders of the manufacturers is closely coupled with the load status of the production lines. The decision on whether to accept an order or not, or the selection of optimal order set among excessive orders is entirely dependent on the schedule of production lines. However, in the real world, since the production scheduling activity is mainly performed by human experts, most of small manufacturers are suffer from being unable to meet due dates, lack of rapid decision on the acceptance of new order. Recently, Internet based Electronic Commerce is recognized as one of the alternatives for strengthening sales power of small and medium companies. However, small and medium manufacturers can’t adjust properly to the new environment because they are in short of money, personnel, and technology. To cope with this problem, this paper deals with development of part sales agent coupled with virtual manufacturing in Internet environment that consist of selection agent, advertisement agent, selection agent, negotiation agent, and virtual manufacturing system. This paper develops a time-bounded negotiation mechanism for small and medium manufacturers in agent-based automated negotiation between customers and negotiation agents. Furthermore, to select optimal order set maximized profit, we first formulate the order selection problem with mixed integer programming, but the computation time of IP is not acceptable for real world scale problem. To overcome this problem and dynamic nature of virtual manufacturing, we suggest a genetic algorithm approach, which shows a reasonable computation time for real world case and good incremental problem solving capability.

In an agent-based system, each agent has its own decision making capability and competes, cooperates, and communicates each other with an agent interface. Virtual manufacturing has characteristics as a typical application area of agent-based system: complex and time-bound decision making and negotiation. The time-boundness influences the choice of decision making models and design of protocols for internal and external negotiation. In this paper, we provide a case study which suggests a time-bound framework for external and internal negotiation between the agents for virtual manufacturing environment. We illustrate decision making model selection strategy and the system architecture of the agent-based system for the complex and time-bound environment.

Although online social network services widely used in human networking and recruiting industries, it is showing off its limitations in followings-it’s hard to reach the status of seamless connection between offline and online; the incompletion and low credibility of the information came from non-face-to-face profile exchange; and the restraint of user autonomy due to centralized control. This paper defines the ubiquitous social network management which enables the seamless real-time face-to-face social interactions of the users based on WPAN (Wireless Personal Area Network) who share the same interest in real word and deduces a ubiquitous social network management framework based on it. As an instance of ubiquitous social network management, u-Recruiting service model will be designed and analyzed. The Analysis using the business model will be followed by the possible scenario of service model. The role, value proposition and potential benefits of the each participants in this service model and will be given as well. In order to evaluate relative advantages of the model suggested by this study, 6 cases will be compared.
