It's a trend that the proportion of using an internet messenger among on-line communication methods is getting increased. However, there are not many applications which efficiently utilize these messenger communication data. Messenger communication data have specific characteristics that reflect the user's linguistic habits. The linguistic habits are revealed through frequently used words and emoticons, and user's emotions can be grasped by these. This paper proposes the method that efficiently classifies the emotions of a messenger user using frequently used words or symbols. The emotion classifier from repeated experiments achieves high accuracy of more than 95%.

Recently, embedded system which demand is explosively increasing in the fields of communication, traffic, medical and industry facilities, expands to cyber physical system (CPS) which monitors and controls the networked embedded systems. In addition, internet of things(IoT) technology using wearable devices such as Google Glass, Samsung Galaxy Gear and Sony Smart Watch are gaining attention. In this situation, Samsung Smart Home and LG Home Chat are released one after another. However, since these services can be available only between smart phones and home appliances, there is a disadvantage that information cannot be passed to other terminals without commercial global messaging server. In this paper, to solve above issues, we propose the structure of an indoor location network based on unit space, which prevents the information of the devices or each individual person from leaking to outside and can selectively communicate to all existent terminals in the network using IoT chatting. Also, it is possible to control general devices and prevent external leakage of private information.

In accordance with development of smart phone, the importance of keypad was increasing, because the smart phone provides a variety of feature like word processor, chatting program, messenger and etc. In this paper, we propose the new Hangeul keypad for smart phones using gestures. And, also we do experiment for performance evaluation of the proposed keypad in this paper. The experiment shows that the proposed keypad is more efficient than other keypads.

In this paper, we implemented an e-mail and chat program (client) for communication between mobile devices and PCs based on WIPI a South Korea's open wireless platform form developing device and content independent software to break from the way of developing contents that is dependent on different wireless platforms to each mobile communications company. While traditional e-mail and chat programs are written for PC-to-PC communication, we develop them for mobile-to-PC and mobile-to-mobile communications, and we expect to see various mobile contents in the future.

채팅 시스템은 사람이 사용하는 언어로 컴퓨터와 의사소통을 하는 시스템이다. 최근 딥 러닝이 큰 화두가 되면서 다양한 채팅 시스템에 관한 연구가 빠르게 진행 되고 있다. 본 논문에서는 문장을 Recurrent Neural Network기반 의사형태소 분석기로 분리하고 Attention mechanism Encoder-Decoder Model의 입력으로 사용하는 채팅 시스템을 제안한다. 채팅 데이터를 통한 실험에서 사용자 문장이 짧은 경우는 답변이 잘 나오는 것을 확인하였으나 긴 문장에 대해서는 문법에 맞지 않는 문장이 생성되는 것을 알 수 있었다.

본 논문은 XML 기반의 문자 메시지를 전송하는 실시간 채팅 시스템을 제안한다. 기존 채팅 시스템은 대부분 의사 전달을 위하여 고정된 크기의 문자 메시지를 사용함으로써, 사용자의 의도를 효율적으로 표현하기 어렵다. 그러므로, 본 논문에서는 사용자 대화의 높낮이 및 행위를 효율적으로 표현하기 위하여 XML 기반의 메시지를 이용하여 다양한 효과를 제공한다. 제안한 시스템의 구성은 클라이언트/서버 구조를 가지며, 클라이언트는 브라우저에서 수행 가능한 자바 애플릿으로 구현하였다. 응용분야로는 온라인 게임 및 교육 등이다.

아웃도어는 일상공간과 자신으로부터의 탈출이라는 의미가 있다. 아웃도어 활동을 보조하는 다양한 어플리케이션이 있으며 대부분 어플리케이션은 서버에 등록된 코스를 스마트폰에 출력하고, 사람들과 대화하기위한 메신저 기능을 제공한다. 이 논문에서는 지도를 공유하며 채팅을 할 수 있는 웹 어플리케이션 설계을 제시한다.

인터넷의 등장은 참고봉사 분야에 많은 변화를 가져왔다. 미국 등 선진국의 도서관에서는 채팅이라고 하는 새로운 참고봉사 기법이 등장하여 이용자들에게 신속하고 편리한 서비스를 제공하고 있다. 본 연구에서는 채팅서비스 운영사례를 통해 채팅서비스의 특징 및 장단점을 살펴보고 국내 도서관에서의 운영 방안을 모색해 보고자 한다.
