본 논문에서는 영화의 등장인물의 성향을 파악하기 위해 시나리오의 대사로부터 감정어를 추출하고, 등장인물의 감정어들을 긍정, 부정, 중립의 3개로 단순화하여 등장인물의 성향을 가시화 시켜주는 방법을 제안한다. 대사로부터 감정어를 추출하기 위해 WordNet 기반의 감정어 추출 방법을 제안한다. WordNet은 단어 간에 상위어와 하위어, 유사어 등의 관계로 연결된 네트워크 구조의 사전이다. 이 네트워크 구조에서 최상위의 감정 항목과의 거리를 계산하여 단어별 감정량을 계산하여 대사를 30 차원의 감정 벡터로 표현한다. 등장인물별로 추출된 감정 벡터를 긍정, 부정, 중립의 3개의 차원으로 단순화 하여 등장인물의 성향을 표현한다.

The purpose of this study is to figure out how a child, as an active responder, responds to the characters of fantastic picture books by analyzing the child's questions and comments through the reading aloud approach. The subjects of this study are fifty-four children under five years old. Nine fantastic picture books are used as the study materials. The contents of the analysis are the frequency of children's questions and comments, the types of responses and the reasons of preferences to the characters. The results of the analysis are as follows: Firstly, the frequency of comments is three times higher than the frequency of questions. Secondly, the frequency of "evaluative questions" is the highest and "imaginative questions" is the next highest. The frequency of "transparent questions" and "personal questions" are comparatively low. Thirdly, most of the children answered that the reason of preference of the characters was "the character's appearance" and then "their subjective feeling to the character", "the character's role" and "the character's characteristics" in that order. Only one child answered that it was "the character's gender." This study will contribute to the planning and implementation of the strategies of reading picture books and to the strategic study to improve children's responses as well.

기계학습 기술이 발달함에 따라 기계학습은 제한된 상황에서 벗어나, 실생활과 비슷한 복잡하고 다양한 상황에서의 학습이 중요한 이슈가 되었다. 본고에서는 현실과 비슷한 상황을 도입하기 위하여 드라마를 사용한다. 드라마 내의 등장인물들은 말투, 어조, 관심주제와 같이 다양한 특성을 내재하고 있다. 등장인물들의 다양한 특성 중 관심주제는 대본 안에 글로 드러나 있으므로 기계학습을 통해 등장 인물의 인식에 활용할 수 있다. 최근, 확률그래프모델 분야에서 문서의 주제를 다루는 기법으로 자주 거론되는 토픽 모델 중 하나인 Author-Topic (AT) 모델은 등장인물의 관심주제를 학습하는 데에 적합하다. 본 논문에서는 AT 모델로 대본을 학습하고, 학습된 데이터 분포를 이용하여 장면에 등장하는 인물들을 인식하는 방법을 제시한다. 이 방법의 성능을 측정하기 위해, 미국 TV 드라마 'Friends' 대본 39편을 학습시키고, 장면에 대해 등장인물을 인식하는 실험을 수행하였다. 이 실험을 통해 본고에서 Author-Topic 모델을 이용한 인물 인식 방법이 다수의 인물이 참여한 담화의 인물들을 인식하는데 강점이 있음을 확인할 수 있다.

In this paper, we propose a system that can analyze appearance interval of casts by detecting and recognizing casts in broadcasting videos. The cast is one of the most important characteristics in broadcasting videos such as drama and sports. In this paper, we propose the ACAV(Automatic Cast-list Analysis in Videos) system that analyzes cast-list automatically in video. The ACAV system consists of FAGIS(FAce reGIStration) which registers detected faces into the face DB and FACOG(FAce reCOGnition) that analyses the cast-list in video sequence using the face DB. We evaluate performance of the ACAV system by comparing with FaceIt, one of the most well-known commercial systems for the cast-list analysis. The ACAV shows face detection and recognition rates of 84.3% and 75.7% that are about 30% and 27.5% higher than those of FaceIt, respectively. The ACAV system can be applied to mass broadcasting videos management system for broadcasters and video management system of PVR(Personal Video Recorder) and mobile phone for the public.

With the fast development of complex science, lots of social networks are studied. We know that the social network is widely applied in analyzing issues in human culture, economics and web sciences. Recently we witness that some researchers began to compare the social network constructed from fiction literatures(literature social network) and the real social network obtained from practice. But we point that previous approaches for literature social network have some drawbacks since they completely depend on the biographical dictionary constructed for a designated literature. So since the previous approach focus on the few important characters and peoples around them, we can not understand the global structure of all characters appeared in the literature at least once. We propose one method to extract all characters appeared in the literature and how to make the social network from that information. Also we newly propose K-critical network by applying frequency of the named characters and the strength of relationship among all textual characters. Our experiment shows that the K-critical measure could be one crucial quantitative measure to compute the relationship strength among characters appeared in the object literature.

본 논문에서는 등장 인물 검출 및 인식과 함께 등장 인물의 출연 구간 분석이 가능한 시스템을 제안한다. 드라마, 스포츠와 같은 방송 비디오는 그 특성상 인물이 중심이 되며 각 시점에 등장하는 주요 인물은 방송용 비디오의 중요한 특징이 된다. 따라서 방송용 비디오의 중요한 특징인 등장 인물을 분석하여 효율적인 비디오 관리 시스템을 개발할 수 있다. 본 논문에서 제안된 ACAV(Automatic Characters Analysis in Videos) 시스템은 등장 인물을 검출하여 인물 DB에 등록하는 FAGIS(FAce reGIStration)와 생성된 인물 DB을 이용하여 등장 인물을 분석하는 FACOG(FAce reCOGnition)로 구성된다. 상용화된 등장 인물 분석 시스템인 FaceIt과의 성능 비교를 통해 ACAV의 성능을 검증하였다. 얼굴 검출 실험에서 ACAV의 얼굴 검출률은 84.3%로 FaceIt 보다 약 30% 높았고, 얼굴 인식 실험에서도 ACAV의 얼굴 인식률은 75.7%로 FaceIt 보다 27.5% 높은 성능을 보였다. ACAV 시스템은 방송 멀티미디어 공급자를 위한 대용량 비디오 관리 시스템으로 이용될 수 있으며 일반 사용자를 대상으로 한 PVR(Personal Video Recorder), 모바일 폰 등의 비디오 관리 시스템으로도 이용될 수 있다.

There are various approaches that retrieve information from video. However, previous approaches have considered just object information and relationship between objects without story information to retrieve contents. To retrieve exact information at video, we need analyzing approach based on characters and community since these are body of story proceeding. Therefore, this paper describes video information retrieval methodology based on character information. Characters progress story to form relationship through conversations. We can analyze the relationship between characters in a story with the methods that classifies role grades and clusters communities of characters. In this paper, for these, we propose the Character-net and describe how to classify role grades and cluster communities at Character-net. And we show this method to be efficient.

This study aimed to apply the principle of the semantic network to a long novel in an attempt to understand the structure of the entire document and the manifested relationships between words and words. The costume expressions in Murakami's novel Norwegian Wood were analyzed based on the characters' symbols, relationships, and personality characteristics. The study identified the symbols of the characters in the novel and the relationship properties between the characters through the Clauset-Newman-Moore clustering algorithm. The descriptions and symbols of the relationships between the characters were identified within the worldview that the author had intended. Further, it was confirmed that the expression of each costume according to the character's personality was also connected to the clue that explained said character. This fusion study is academically significant in that it presents a new methodology for analyzing literary works

In this paper, I propose and evaluate the method that classifies emotional type of characters with their emotional words. Emotional types are classified as three types such as positive, negative and neutral. They are selected by classification of emotional words that characters speak. I propose the method to extract emotional words based on WordNet, and to represent as emotional vector. WordNet is thesaurus of network structure connected by hypernym, hyponym, synonym, antonym, and so on. Emotion word is extracted by calculating its emotional distance to each emotional category. The number of emotional category is 30. Therefore, emotional vector has 30 levels. When all emotional vectors of some character are accumulated, her/his emotion of a movie can be represented as a emotional vector. Also, thirty emotional categories can be classified as three elements of positive, negative, and neutral. As a result, emotion of some character can be represented by values of three elements. The proposed method was evaluated for 12 characters of four movies. Result of evaluation showed the accuracy of 75%.

컴퓨터 그래픽스의 발전과 함께 등장한 가상인물은 최근 영화, TV, 게임 등의 다양한 매체에서 자주 접할수 있게 되었다. 가상인물은 사람을 닮은 등장인물로서, 그 생김새나 사실적인 동작, 자연스러운 얼굴 표정등이 관심의 대상이 된다. 특히, 얼굴 생김새나 표정은 가상인물을 개성 있는 인물로 재창조하는데 중요한 역할을 한다. 사람들은 타인의 얼굴 표정에 대해 매우 민감하게 반응하기 때문에 가상인물의 얼굴 표정을 제어하기가 더욱 어렵다. 가상인물의 얼굴 모델을 제작하고, 모델에게 표정을 부여하기 위해서 오래 전부터 다양한 방법들이 연구되어 왔다. 본 고에서는 가상인물의 얼굴 모델을 제작하고, 표정을 생성하는 방법에 관해 조명해 본다.
