The users of a chatbot messenger can be better engaged in the conversation if they feel intimacy with the chatbot. This can be achieved by the chatbot's effective expressions of human emotions to chatbot users. Thus motivated, this study aims to identify the appropriate emotional expressions of a chatbot that make people feel the social presence of the chatbot. In the background research, we obtained that facial expression is the most effective way of emotions and movement is important for relationship emersion. In a survey, we prepared moving text, moving gestures, and still emoticon that represent five emotions such as happiness, sadness, surprise, fear, and anger. Then, we asked the best way for them to feel social presence with a chatbot in each emotion. We found that, for an arousal and pleasant emotion such as 'happiness', people prefer moving gesture and text most while for unpleasant emotions such as 'sadness' and 'anger', people prefer emoticons. Lastly, for the neutral emotions such as 'surprise' and 'fear', people tend to select moving text that delivers clear meaning. We expect that this results of the study are useful for developing emotional chatbots that enable more effective conversations with users.

정보추출(information extraction), 질의-응답 시스템(Question-Answering system) 등의 자연언어처리 응용분야에서 시간과 사건에 관련한 정보를 추출하는 것은 중요한 부분이다. 그럼에도 불구하고, 한국어의 자연언어처리 응용분야에서는 아직까지 이 연구가 본격화되지 않았다. 미국 TARSQI 프로젝트의 연구결과를 바탕으로 하여 한국어 텍스트에서 시간 및 사건 표현의 주석, 추출, 추론을 위한 명세 언어(KTimeML), 주석 말뭉치(KTimeBank), 자동 태깅 시스템(KTarsqi Toolkit: KTTK)의 개발을 목표로 2008년 KTARSQI 프로젝트가 시작되었다. 이 논문에서는 KTARSQI 프로젝트의 목표와 과제에 대한 전반적인 소개와 함께, 현재까지 진행된 작업의 결과로서 사건 태그의 명세와 주석에 관한 논의를 덧붙인다.

Characters' nonvocal communication plays an essential role in delivering lines and expressing emotions. A character in a game is represented with its nonvocal behavior combined with a large number of lines. In this paper, characters' nonvocal communication behaviors are categorized and analyzed. Furthermore, characters' gestures and movements are designed with bones for character gesture generation in 2D games. Besides, characters' movements are visualized. In brief, a nonvocal communication system for emotional expression of characters in 2D games is proposed.

트위터는 최대 140자의 단문을 주고받는 소셜 네트워크 서비스이다. 트위터의 해시 태그는 주로 문장의 핵심 단어나 주요 토픽 등을 링크하게 되는데 본 논문에서는 이러한 정보를 이용하여 키워드 추출에 활용한다. 문장을 Character CNN, Bi-LSTM을 통해 문장 표현을 얻어내고 각 Span에서 이러한 문장 표현을 활용하여 Span 표현을 생성한다. Span 표현을 이용하여 각 Span에 대한 Score를 얻고 높은 점수의 Span을 이용하여 키워드를 추출한다.

We propose a systematic method of compiling Haskell based on the spineless Tagless G-machine (STGM) for the Java, Virtual Machine (JVM) We introduce an intermediate language called L-code to identify each micro-operation of the machine by its instruction, Each macro operation of the machine is identified by a binding Each instruction of the L-code can be easily translated into Java statements. After our determination on representation and L-code program from a STG program is translated into Java program according to out compilation rules. Our experiment shows that the execution times of translated benchmarks are competitive compared with those in Haskell interpreter Hugs, particularly when Glasgow Haskell compiler's STG -level optimizations are applied.

This paper is the outcome of attempting to approach for reading the Analects of Confucius through the polysemy of Chinese character and indecidability of articles. For this purpose at first, I explained which this Chinese character can be applied for 'philosophy language'. In the 16th century Matteo Ricci had tried to find out the possibility of ideographic script as standing for a universal language. On the other hand, Hegel and Heidegger strictly insisted on the Chinese character is inappropriate for expressing the logic thought of the human being. The reason was as next; firstly, this character had not the preposition and articles, and secondly the only one word could not indicates the bisemy including the meaning of opposition, lastly this language system expresses and communicates only with the change of word order without inflection. But With some scholar like Cassirer, Saussure and Derrida we can confirm the possibility which will discover the Chinese character for using the logic and reasoning language of from different view. Because in the language system of this Chinese character the connection of words in contexts is more important other than meaning as the individual word, in comparison to the language of the West. The Chinese character hides the original meaning until being what kind of event and thing relationship watch inside with different letters. So to speak, the Chinese character is called as 'language of indecidability'. For these points, even though The Chinese character lacks of preposition, articles, and inflection speech etc. the letter systematic, this language system can play a role for expressing as the philosophic language which manages with the complicated problems of the human being.

본 논문은 "집합 일치화 문제(set unification problem)"를 논리 언어 Prolog를 사용하여 구현한다. 집합 일치화 문제는 고전적 논리 언어(logic languages)의 일치화 문제(unification problem)에서 집합을 표현할 수 있도록 확장한 것으로 최근 연구되고 있는 "집합 제한 논리 언어(set constraints logic languages)"를 구현하기 위하여 풀어야 하는 문제이다. 본 논문에서는 최근 A. Dovier 연구팀이 제안한 집합 일치화 문제의 풀이(solver)를 소개하고, 이 풀이를 논리 언어 Prolog를 사용하여 구현하는 방법을 기술한다. Prolog 언어는 비결정성(nondeterminism)을 표현할 수 있는 기능과 리스트(list)라는 자료 구조를 제공하는 기능 때문에 다른 어떤 언어에서보다 쉽게 집합 일치화 문제 풀이를 구현할 수 있다. 본 연구의 결과는 집합 제한 논리 언어의 수행기(interpreter) 개발에 직접 이용될 수 있다.

Mentally disable children feel as failure because they have difficulty in restricted and undifferentiated communications with others. It also makes the counter-partner feel frustrated. Therefore, in the aspects of language acquirement and communication activities, it is essential to let the disable children learn and communicate voluntarily. Music provides the unthreatening and interesting stimulus as non-language communication vehicle. Musical experiences for mentally disable children's are multi-stimulating experiences that make a positive influence in speech and language development and development of variety of talents. There are many communication intervention and method to treat the mentally disable children. One of the most effective treatments for mentally disable children to acquire communication techniques by expressing the language more naturally and joyfully is the musical therapy. This study analyzes children's communication technique referring to response action and attempt action through video tape observation. Also, this study measured the receptive and expressive language by PRES(Preschool Receptive-Expressive Language Scale) as a test tool in order to examine the pre-post language ability for respective children as pre-post period of therapy activity. First result of this study showed that music therapy with song was effective for mentally disable children in enhancing the communication techniques centered with communication response and in attempt action by increasing the communication action incidence. Secondly, pre-post comparison test with PRES showed that the music therapy with song was effective on improvement the receptive and expressive language ability of 4 children.

The purpose of this study is to find the effect of home environmental stimuli and mothers' personal variables in multicultural family on children's linguistic abilities. The object of this study is 132 infants and their mothers of 82 infant education institutes located in P city. The main results of the study are as follows: First, the means of communication (generally Korean) is found to have the greatest effect 0n children's linguistic abilities of the personal variables of mothers from multicultural families. Second, the formation of stable and predictable environments affects children's linguistic abilities (receptive and expressive language) most of all the home environmental stimuli. Third, children's receptive language was most affected by the formation of stable and predictable environments, and their expressive language was most affected by the aspects of physical environments.
