In this paper, we propose a novel approach to employ emotional features to document retrieval systems. Fine emotional features, such as HAPPY, SAD, ANGRY, FEAR, and DISGUST, have been used to represent Korean document. Users are allowed to use these features for retrieving their documents. Next, retrieved documents are learned by classification methods like cohesion factor, naive Bayesian, and, k-nearest neighbor approaches. In order to combine various approaches, voting method has been used. In addition, k-means clustering has been used for our experimentation. The performance of our approach proved to be better in accuracy than other methods, and be better in short texts rather than large documents.

본 논문에서는 음성 신호로부터 감정의 특징을 나타내는 요소를 찾아내는 것을 목표로 하고 있다. 일반적으로 감정을 인식할 수 있는 요소는 단어, 톤, 음성신호의 피치, 포만트, 그리고 발음 속도 및 음질 등이 있다. 음성을 기반으로 감정을 익히는 방법 중에서 현재 가장 많이 접근하고 있는 방법은 피치에 의한 방법이 있다. 사람의 경우는 주파수 같은 분석 요소보다는 톤과 단어, 빠르기, 음질로 감정을 받아들이게 되는 것이 자연스러운 방법이므로 이러한 요소들이 감정을 분류하는데 중요한 요소로 쓰일 수 있다. 따라서, 본 논문에서는 감정에 따른 음성의 특징을 추출하기 위해 사람의 감정 중에서 비교적 자주 쓰이는 평상, 기쁨, 화남, 슬픔에 관련된 4가지 감정을 비교 분석하였으며, 인간의 감정에 대한 음성의 특성을 분석한 결과, 강도와 스펙트럼에서 각각의 일관된 결과를 추출할 수 있었고, 이러한 결과에 대한 실험 과정과 최종 결과 및 근거를 제시하였다. 끝으로 실험에 의해 제안한 방법의 유용성을 입증하고자 한다.

From several commercialized games the technique of changing facial expressions is imported, and a design method of a game character for the player's empathy is expected to be diversified in the future. In this paper, as a design method of a game character for the player's empathy, this makes walking motion for the game character applied with 'human-emotion' factors as statistics variation of a game character in RPG genre. After this paper implements analyzed emotions of human facial expression and walking motions applied with emotion in examples of character animation theory, this paper divides walking motion applied with human-emotion factors into 8 types through relationship to statistics factors in RPG genre. And then these are applied to a knight character, which has the most similarity with human's physical feature of the game characters in RPG genre, and makes walking motion as variable statistics. As a game player controls the game character applied with 'human-emotion' factors, the effect of the player's empathy about the game character becomes higher, and the level of immersion in game play is also expected to increase.

This ethnographic study aimed to understand the emotional labor of traditional performing artists who hide and control their emotions in performances and the components and characteristics of their emotional labor by means of in-depth interviews with traditional performing artists and Giorgi's analysis method. As a result of the analysis, first, the factors that lead to emotional labor of traditional performing artists can be divided into external and internal ones. The external factors arose from expressing various emotions while creating or suppressing their own emotions in an effort to draw out the emotions of the audience. Also, emotional labor occurred depending on the performance place, performance type and audience reaction. The internal factors consisted of the emotional burden experienced due to concerns over mistakes and audience satisfaction as they voluntarily commit themselves to the performance in order to satisfy the audience. Second, complex emotions that remain after the performance sometimes lead to aftereffects of emotional labor. Third, factors of emotional labor that originate from belonging to an organization had an influence, which resulted in their considering job change or resignation. Fourth, emotional labor arises from the specificity of the traditional performing arts field, that is, negative perceptions and unfair internal practices of traditional performing arts. The study showed that traditional performing artists relieve their emotional labor through hobbies and chatting with colleagues, and took the emotional labor as granted, not recognizing that the occupational emotional labor as emotional labor. This study is significant in that it recognized and analyzed traditional performing artists as emotional workers and focused on the emotional labor components of traditional performing artists.

The study was to investigate the effect of the environmental factor on the emotion and satisfaction at the waiting lounge of the international cruise terminal. The results of the study were found as follows: first, the physical environmental factor of the lounge influenced on the positive emotion. Second, the social factor affected the positive emotion. Finally, emotion affected the positive satisfaction. This study suggested that environmental factor was totally affected by emotion and thus environmental management depended on an individual characteristics of the individual place. The port authority will need more efforts to make a better waiting lounge setting for higher tourist satisfaction.

The study was to investigate the effect of the environmental factor on the emotion and satisfaction at the waiting lounge of the Busan International Cruise Terminal. This study focus on tourist at the waiting area in the Busan International Cruise Terminal. The data was collected through self-administered questionnaires and the research performed to face-to-face interview. For data analysis, used SPSS 18.0 and AMOS 18.0 of a structural equation model. The results of the study were found as follows: first, the physical environmental factor of the lounge influenced on the positive emotion. Second, the social factor affected the positive emotion. Finally, emotion affected the positive satisfaction. This study suggested that environmental factor was totally affected by emotion and thus environmental management depended on an individual characteristics of the individual place. The port authority will need more efforts to make a better waiting lounge setting for higher tourist satisfaction.

본 논문에서는 감정 표현 음성 합성 시스템을 구현하기 위해서, 감정 음성 데이터베이스의 음향학적 특징인 피치, 에너지, 지속시간, 스펙트럼 포락에 대해 분석한 결과와 문법적 요소인 품사에 따른 감정 음성 데이터의 피치 변화를 분석하였다. 분석 결과, 기본 주파수, 에너지, 지속시간, 스펙트럼 포락은 감정 표현에 중요한 영향을 미치는 것으로 나타났으며, 전반적으로 화남과 기쁨의 감정이 평상과 슬픔의 감정 보다 피치 및 에너지의 변화가 크게 나타났으며, 특히 기쁜 감정의 경우 부사, 관형사, 연결어미, 조사, 접미사에서 피치 변화가 많았으며, 화난 감정의 경우, 관형사, 명사, 용언, 접미사에서 피치 변화가 높게 나타났다. 이러한 분석 결과를 적용해 감정 음성을 합성하기 위하여, 평상 음성에 각 감정 음성의 운율 요소를 적용하여 감정 음성을 합성하여 평가한 결과, 기쁜 감정은 기본 주파수의 변화에 의해 86.7%, 화난 감정은 에너지의 변화에 의해 91%, 슬픈 감정은 음절지속시간의 변화에 의해 76.7%가 각각 올바른 감정으로 인지되었다.

In this paper, we examine the role of emotional acoustic cues including both prosody and voice quality parameters for the modification of a word sense. For the extraction of prosody parameters and voice quality parameters, we used 60 pieces of speech data spoken by six speakers with five different emotional states. We analyzed eight different emotional acoustic cues, and used a discriminant analysis technique in order to find the dominant sequence of acoustic cues. As a result, we found that anger has a close relation with intensity level and 2nd formant bandwidth range; joy has a relative relation with the position of 2nd and 3rd formant values and intensity level; sadness has a strong relation only with prosody cues such as intensity level and pitch level; and fear has a relation with pitch level and 2nd formant value with its bandwidth range. These findings can be used as the guideline for find-tuning an emotional spoken language generation system, because these distinct sequences of acoustic cues reveal the subtle characteristics of each emotional state.

최근 게임 산업에서는 게임을 인공지능적인 측면으로 접근하는 방식 중 하나로 인공감정을 주목하고 있다. 인공감정은 감정자극과 감정, 그리고 감정의 표현 방식이라는 총 3가지 기본요소로 이루어져 있다. 본 연구에서는 인공감정을 사람들에게 꾸준하게 인지도가 상승하고 있는 캐주얼 게임에 적용시켜 보았다. 캐주얼 게임은 다른 게임들에 비해 게임 속에서 감정을 느낄 수 있는 환경요소가 한정적이고, 표현할 수 있는 감정이 적어 인공감정에 대한 플레이어의 반응을 실험하기에 적합한 게임 장르이다. 본 연구에서는 쉽게 제작 가능한 버튼 클릭 방식의 캐주얼 게임을 만들었다. 그리고 게임에 플레이어의 행동을 통해 감정적 영향을 받는 인공감정이 적용된 게임 에이전트를 제작했다.

감정을 표현하는 음성 합성 시스템을 구현하기 위해서는 감정음성에 대한 분석이 필요하다. 본 논문에선,s 평상, 화남, 기쁨, 슬픔의 네 가지 감정에 대한 음성 데이터에 대해 음절 세그먼트, 라벨링을 행한 감정 음성 데이터베이스를 구축하였고, 감정표현이 음성에 영향을 미치는 요인에대하여, 운율, 음운적인 요소로 나누어 분석하였다. 또한 기본 주파수, 에너지, 음절지속시간에 대한 분석과 감정 음성의기본 주파수, 에너지, 음절지속시간, 스펙트럼 포락의 인지 정도를 측정하기 위하여 평상 음성에 감정 음성의 운율 요소를 적용하는 음성을 합성하여 ABX 방법으로 평가하였다. 그 결과, 기본 주파수의변화가 73.3%, 음절지속시간은 43.3% 로 올바른 감정으로 인지되었으며, 특히 슬픈 감정에서 음절지속시간은 76.6%가 올바르게 감정을 나타내는 것으로 인지되었다.
