인터넷이 폭 넓게 보급되어 개인의 의견을 개진할 기회가 확대됨에 따라 정치, 경제 등의 사안이나 제품 기업의 이미지, 공인에 대한 긍정.부정의 글을 개진할 수 있게 되었다. 이러한 현상에 따라 기업, 제품, 혹은 공공의 분야에서 일반 개인들이 어떻게 생각하는가에 대한 분석 및 자료수집의 필요성이 높아지고 있다. 감성용어 문서분류시스템은 문서의 내용 중 감성기반의 용어들에 기반하여 이에 대한 패턴을 정의하고 이에 대응하는 범주에 문서를 자동으로 할당하는 작업으로써 효율적인 정보 관리 및 검색을 가능하게 한다. 하지만 자동문서 분류를 하기 위해서는 방대한 양의 데이터를 수집 보관하기 위한 분산 환경이 반드시 필요하다. 본 논문에서는 감성기반 문서분류 시스템을 위한 감성용어 추출 및 긍정, 부정의 패턴을 검색해 자동 문서분류를 위해 RTI(Run Time Infrastructure)를 통한 분산 시스템 환경으로 구성하였다.

Emotion intelligence computing is able to processing of human emotion through it's studying and adaptation. Also, Be able more efficient to interaction of human and computer. As sight and hearing, music & image is constitute of short time and continue for long. Cause to success marketing, understand-translate of humanity emotion. In this paper, Be design of check system that matched music and image by user emotion keyword(irritability, gloom, calmness, joy). Suggested system is definition by 4 stage situations. Then, Using music & image and emotion ontology to retrieval normalized music & image. Also, A sampling of image peculiarity information and similarity measurement is able to get wanted result. At the same time, Matched on one space through pared correspondence analysis and factor analysis for classify image emotion recognition information. Experimentation findings, Suggest system was show 82.4% matching rate about 4 stage emotion condition.

The requirement of Digital Culture Content(Movie, Music, Animation, Digital TV, Exhibition and etc.) is increasing so variety and quantity of content is also increasing. The Movie what majority of the digital Content is developing of technology and data. In the result, the efficient retrieval service has required and user want to use a recommendation engine and semantic retrieval methods through the recommendation system. Therefore, this paper will suggest analysing trait element of digital content data, building of retrieval technology, analysing and retrieval technology base on KANSEI vocabulary and etc. For the these, we made a extraction technology of trait element based on semantics and KANSEI processing algorithm based on color information.

This paper proposes a Image retrieval system that searches the closest images to the user's emotional need and displays images with higher ratings of color harmony from Moon-Spencer's Color Harmony Theory first. Once an emotional adjective is placed, the system searches for images with colors that contain more elements derived from Aesthetic Measure results and displays in such order. In order to test reliability of the proposed emotion retrieval method based on Moon-Spencer's Color Harmony Theory, this study compared the order of Aesthetic Measure results with the user satisfaction ratings using 200 sample images. The analysis demonstrated that the participants' average satisfaction on 15 emotion adjectives selected for the study was 5.0 on a 7-point Likert scale. Correlation analyses were performed to test the consistency the orders between Aesthetic Measure values and user satisfaction ratings. Positive correlations above R=.5 were observed in all 14 emotion words except "Clear". These findings prove the potential of the proposed emotion retrieval system based on Moon-Spencer's Color Harmony Theory to effectively reflect user emotion in such visual stimulus search as image database.

In this paper, we propose the construction of multi-queries and consistency principle for the user's emotion-based music retrieval system. The features used in the system are MPEG-7 audio descriptors, which are international standards recommended for content-based audio retrievals. In addition we propose the method to determine the weight that represent the importance of each descriptor for each emotion in order to reduce the computation. Also, the proposed retrieval algorithm that uses the relevance feedback based on consistency principal and multi-queries improves the success ratio of musics corresponding to user's emotion.

As the information and the network technology are improved, the system which can express the interactions between the individuals becomes to play more important roles in these days. In fact, that tendency is especially well shown in the community area of P2P and social network service programs. This paper suggest an intelligent character manipulation system which can be effectively used to express emotional representation in an intelligent way in spite of many constraints. The system employs an emotion searching mechanism by attaching emotional information to each object in the database and defining a function of emotional similarity. It is expected that the system can be successfully used not only to find and represent the suitable emotional character representations but also to provide brand new services in the area of mobile platform based contents.

For an emotion retrieval system implementation to support pedestrian navigation, coordinating the pedestrian emotion model with the system user's emotion is considered a key component. This study proposes a new method for capturing the user's model that corresponds to the pedestrian emotion model and examines the validity of the method. In the first phase, a database comprising a set of interior images that represent hypothetical destinations was developed. In the second phase, 10 subjects were recruited and asked to evaluate on navigation and satisfaction toward each interior image in five rounds of navigation experiments. In the last phase, the subjects' feedback data was used for of the pedestrian emotion model, which is called ‘learning' in this study. After evaluations by the subjects, the learning effect was analyzed by the following aspects: recall ratio, precision ratio, retrieval ranking, and satisfaction. Findings of the analysis verify that all four aspects significantly were improved after the learning. This study demonstrates the effectiveness of the learning algorithm for the proposed pedestrian emotion model. Furthermore, this study demonstrates the potential of such pedestrian emotion model to be well applicable in the development of various mobile contents service systems dealing with visual images such as commercial interiors in the future.

Being digitalized, the music can be easily purchased and delivered to the users. However, there is still some difficulty to find the music which fits to someone's taste using traditional music information search based on musician, genre, tittle, album title and so on. In order to reduce the difficulty, the contents-based or the emotion-based music retrieval has been proposed and developed. In this paper, we propose new method to determine the importance of MPEG-7 low-level audio descriptors which are multi-dimensional vectors for the emotion-based music retrieval. We measured the mutual similarities of musics which represent a pair of emotions expressed by opposite meaning in terms of each multi-dimensional descriptor. Then rough approximation, and inter- and intra similarity ratio from the similarity relation are used for determining the importance of a descriptor, respectively. The set of weights based on the importance decides the aggregated similarity measure, by which emotion-based music retrieval can be achieved. The proposed method shows better result than previous method in terms of the average number of satisfactory musics in the experiment emotion-based retrieval based on content-based search.

면접자나 면접관이나 인재들이 해당 조직에서 일을 해보지 않고서는 조직문화와 직무에 적합한지에 대해 확신 할 수 없고 만약 적합하지 않다면 면접자나 조직이나 서로 피해를 입는 상황이 발생한다. 이러한 상황들을 개선하기 위해 감성 어휘를 기반으로 한 이미지 스케일과 감성어휘 분류 시스템을 분석한다. 또한 면접자들의 이력서와 자기소개서에 있는 단어들을 분석하여 조직문화와 해당 직무에 적합한 인재 선발에 참고 자료를 제공할 수 있는 감성 어휘를 기반으로 한 인재 검색 시스템에 기초가 되는 이미지 스케일과 감성 어휘 분류체계에 대해 연구한다.

Variable contents are extracted and used to improve the correctness of the retrieval in the content-based in age retrieval. This way use the physical feature for the retrieval. In this way of retrieval, the user has to know the basic physical features and spatial relationship of target images that he wants to retrieve. There are some restriction to reflect the user's intend. We need the retrieval system that reflect the user's intend. In this paper, we propose an emotion-based retrieval system. It is different from past emotion based image retrieval in point of view that it uses relevance feedback to estimate the users intend and it is easily combined with past content-based image retrieval system. The features and similarity measures are adopted from MPEG-7 color descriptors which are proper retrieval of large multimedia databases. We use wallpaper images for the experiment. The result shows that the system get successful result.
