챗봇이란 인공지능 기반으로 인간과 대화하는 로봇을 일컬으며, 요청과 응답구조로 운영되는 인공지능 프로그램을 말한다. 챗봇은 사용자와 상호작용하기 위해 대화형 인터페이스를 사용하는 소프트웨어로 기존 사용자의 언어를 이해하고 학습하여 인간이 대화하듯이 대화를 하도록 설계되어있다. 챗봇을 사용하는 회사는 인건비를 줄이고 빅데이터를 기반으로 전문적이고 정확한 답변을 제공할 수 있어 활용 효율성이 높은 편이다. 그러나 회사가 챗봇을 적극적으로 도입하고 사용자에게 긍정적인 영향을 줄 것이라는 기대와 달리 사용자는 챗봇을 계속 사용하지 않고있다. 따라서 본 논문은 챗봇 서비스의 지속사용의도에 영향을 미치는 요인들을 파악하고자 한다. 특히 인공지능 특성이 챗봇 서비스 지속적 사용의도에 미치는 영향을 연구한다.

본 논문에서는 캐릭터 챗봇을 학습시키고, 학습된 모델을 React 기반 웹 페이지에 통합하는 것을 목표로 한다. 웹 페이지 사용자들은 실시간으로 게임이나 영화 캐릭터와 대화할 수 있는 기능을 제공받게 된다. 캐릭터 챗봇은 사용자의 질문을 이해하고 학습된 캐릭터의 특성에 따라 적절한 응답을 생성함으로써 상호작용하게 된다. 사용자가 웹 페이지에서 입력한 질문이나 요청은 챗봇 모델을 통해 처리되며, AI 챗봇은 학습된 지식과 데이터를 활용하여 응답을 생성한다. 사용자는 웹 페이지에서 자연스러운 대화를 통해 원하는 캐릭터와 대화를 이어갈 수 있게 된다.

This article aims to articulate, via Dilthey's concept of "understanding", that the three reflective conditions of interculturality are compatible with the three theses of "living-together". The former was proposed by Prof. Joo Kwang Sun and the latter is my assertion. In my point of view, the three theses of "living-together" are firstly 'consciousness of relationship to others', secondly 'reciprocity of relating', and thirdly 'sharing of same representation of mutual relationship'. Considering Dilthey's concept of "understanding", we can confirm that his concept includes firstly 'understanding is only for something constructed by spirit', secondly 'it is relation between expression and something expressed', and thirdly 'it means construction of one whole living-together'. Therefore I think Dilthey's concept of "understanding" could be regarded as a medium concept which enables us to integrate the three reflective conditions of interculturality with the three theses of "living-together". So I try to explain compatibility between the three conditions of interculturality and the theses of "living-together".

Recently, as a new ICT trend, emerging chatbots are actively introduced in the field of finance. Chatbot conducts services through the interaction of communication with users. The purpose of this study is to investigate the effect of interaction dialogue type on the efficiency, usability, sensibility and perceived security of financial service chatbot. Based on theoretical considerations, I have divided into closed conversation, open conversation, and mixed conversation type based on the conversation style based on the implementation method of chatbot. Three types of Financial Chatbot prototypes were made and the experiments were conducted after account inquiry, account transfer, Q & A financial task execution. As a result of experimental research analysis, chatbot's interaction dialogue type was found to affect efficiency and usability. Users have shown that the interaction of closed conversations and mixed conversations is an intuitive interface that allows financial services to be easily manipulated without error. This study will be used as a resource to improve the user experience that requires deep understanding of financial chatbot users who should consider both the emotional element of artificial intelligence that provides services through natural conversation and the functional elements that perform financial business can be.

This paper describes the development of an interactive computer graphic software for the education and training of the power system fault analysis. The developed software is designed to increase the understanding of the fault analysis with ease and it is composed of the windows, graphic icons, and graphic representations for user-friendly environments. Specially an interactive scheme is given for user to simulate the fault analysis under the variety conditions. With this function, user can acquire the basic concepts of the power system fault study as well as the understanding of the impacts on the system by some faults. The proposed software is tested on a 16-bus sample system. The software will be useful for the education and training and training of the power system fault analysis.

Journal of Convergence for Information Technology. This study explores how native speakers (NSs) and non-native speakers (NNSs) of English negotiate meanings during conversational interactions to achieve successful communication. This study involved 40 participants: 20 native English speakers and 20 Korean university students. The participants were divided into 20 pairs, with each pair consisting of one NS and one NNS. Tasks for conversation were given and the execution recorded in order to collect data. 37 recorded conversations were transcribed and used for analysis, including statistical analyses. Results showed that both NSs and NNSs mutually put in effort for successful communication. While NSs mostly played the role of leading the natural flow of the conversation, encouraging their non-native interlocutors to speak, NNSs used various strategies to compensate for their lack of linguistic competence in the target language. NNSs employed a wide range of communicative strategies to keep the conversation going. The results of this study contribute to a better understanding of interactions between NSs and NNSs and yield pedagogical implications.

This paper presents a Korean conversational agent system in a mobile environment using natural language processing techniques. The aim of a conversational agent in mobile environment is to provide natural language interface and enable more natural interaction between a human and an agent. Constructing such an agent, it is required to develop various natural language understanding components and effective utterance generation methods. To understand spoken style utterance, we perform morphosyntactic analysis, shallow semantic analysis including modality classification and predicate argument structure analysis, and to generate a system utterance, we perform example based search which considers lexical similarity, syntactic similarity and semantic similarity.

In this study, we introduce trends in neural-network-based deep learning research applied to dialogue systems. Recently, end-to-end trainable goal-oriented dialogue systems using long short-term memory, sequence-to-sequence models, among others, have been studied to overcome the difficulties of domain adaptation and error recognition and recovery in traditional pipeline goal-oriented dialogue systems. In addition, some research has been conducted on applying reinforcement learning to end-to-end trainable goal-oriented dialogue systems to learn dialogue strategies that do not appear in training corpora. Recent neural network models for end-to-end trainable chit-chat systems have been improved using dialogue context as well as personal and topic information to produce a more natural human conversation. Unlike previous studies that have applied different approaches to goal-oriented dialogue systems and chit-chat systems respectively, recent studies have attempted to apply end-to-end trainable approaches based on deep neural networks in common to them. Acquiring dialogue corpora for training is now necessary. Therefore, future research will focus on easily and cheaply acquiring dialogue corpora and training with small annotated dialogue corpora and/or large raw dialogues.

Computing technologies are extending the means by which people communicate. Especially, virtual worlds have recently become successful, due to rapidly improving Information Technologies. Chat is a crucial function in current virtual worlds. We need a realistic and efficient communication framework for multi-agents participating in a virtual world. The main contribution of our work is twofold. First, we propose a realistic communication framework which enables 'Complete Talk' and 'Partial Talk' in terms of spatial relationships between avatar agents. Second, our system reconstructs a dialogue graph which maintains all transcripts in the form of directed graphs with temporal(dialogue sequences) and spatial information(physical positions) about communicating agents.
