<p>In recent years, while data mining has attracted attention, formal concept analysis has the disadvantage that although it can understand the inclusion relation between attributes, it doesn't know what kind of meaning or inclusion relation the attributes have. Therefore, in this study, the inclusion of the attributes and the visualization of the correlation are realized by combining the Hasse diagram by formal concept analysis and the layout diagram of the attribute of quantification theory type III for visualizing the meaning between the attributes. Moreover, in order to confirm usefulness of the proposed method, we developed a simultaneous visualization system of inclusion and correlation combining formal concept analysis and quantification theory type III, and evaluated the proposed method using verification data. As a result, it was confirmed that useful information that can't be obtained only by formal concept analysis or quantification theory type III can be extracted.</p>

The cars are classified by cars' body types. However the characteristics are basically similar at first sight, so it is difficult to distinguish the differences among those cars' body types. Therefore, in this study, we considered that cars' characteristics could be analyzed by using deep learning and image recognition technology, developed a system to visualize the judgment and characteristic parts of cars' body types. Specifically, we made renderings of the CG model of 30 cars by setting 360 viewpoints in 1 degree increments around each car. Deep learning was performed using these 2D images as teacher signals. The car body type recognition probability of each angle is graphed, and the characteristic parts of each car body type are visualized. As a result, we clarified the visual angles and the pars contributing the judgment of cars' body types.

In previous studies, we developed the conceptual structure visualization system (CSVS) by combining rough set theory and formal concept analysis. Furthermore, using CSVS, we found “conflict effect”, “neutralizing effect” and “separation effect” as characteristic conceptual structures that were difficult to find by using conventional methods. In this study, we aimed to verify the practicality of CSVS by analyses for data that is larger than data on previous studies, and to find the characteristic conceptual structure by using CSVS. First, we selected web page designs of luxury brands as case studies, and we conducted questionnaire survey related to preference for 12 web page designs with 46 female subjects. Next, we visualized and analyzed characteristic of conceptual structures of subjects' preferences using CSVS. And we confirmed that CSVS was available to find conceptual structures of preferences. In addition, we discovered new characteristic conceptual structure like compound of “conflict effect” and “neutralizing effect”.

Designers consider cars' proportions using their past experiences and knowledges. However, designers may not search for all patterns of proportion satisfy requirements. In this paper, we aimed to clarify relationships between mini-cars' proportion items and users' impressions. First, we clarified correlations among the proportion items of existing 25 mini-cars using principal component analysis, and created 9 mini-cars' images using the design of experiments. Second, we conducted impression evaluation experiments for 95 subjects using the images. As a result, we clarified relationships between the proportion items and subjects' impressions. Third, we classified subjects into 6 clusters using the difference of their preferences, and clarified the patterns of proportion items that each cluster's subjects feel attractive. Finally, we conducted the evaluation re-experiment for 2 clusters' 20 subjects using the images with the patterns of proportion items preferred by them. As a result, we found strong correlations between mini-cars' heights and their preferences.

In the plan of the products, affective information is utilized with diversification of a life style. Then, in this research, we developed the system that visualizes the difference in affective layered structures of two liquors' reviews (hereafter, visualization system). Specifically, the development consists of the following steps. (1) The visualization system extracts affective words from the reviews on the web. (2) We create the decision table in rough set theory using affective words. (3) The visualization system visualizes the difference in affective layered structures of two liquors using decision rules from each decision table. We conducted the evaluation experiment of the visualization system for 10 subjects. We made five subjects summarize comparison results of two liquors' reviews using the visualization system, and made remaining five subjects summarize them without it. Consequently, the usefulness of the visualization system was verified from the summarized contents and the creation time of them.

データマイニングに利用される分析手法のひとつであるラフ集合は，決定ルールによってある結論に対する属性間の因果関係を簡潔に表現することが可能な一方で，複数の決定ルール間の概念構造（包含関係）を把握しづらいという欠点があった。そこで，本研究では決定ルール間の概念構造を可視化し，ラフ集合の欠点を補う方法論の提案を目的とした。具体的には，属性間の包含関係を主とした概念構造をハッセ図によって可視化することが可能な分析手法である形式概念分析をラフ集合と組み合わせ，双方の分析手法を同時に実行し，ハッセ図上に決定ルールを投影する概念構造可視化システムを開発した。加えて，既存の書籍や論文に掲載されているデータに対するラフ集合解析を用いた分析結果と本システムを用いた分析結果を比較し，システムの有用性を検証した。その結果，異なる決定クラスに属する複数の決定ルールに含まれる属性値や，属性値が有する決定クラスを確定させる影響力の大小など，各分析方法を独立に用いても発見しづらかった知見を得ることができた。

In the plan of products, affective information is increasingly utilized with diversification of a life style. Then, in this research, we had developed the system that visualizes the affective layered structures of liquors' reviews using rough set theory (hereafter, visualization system). Specifically, the development consists of the following steps. (1) The visualization system extracts affective words from the reviews of mail order sites. (2) We create the decision table in rough set theory using affective words. (3) We visualize the affective layered structure using the computed decision rules from decision table. We conducted the evaluation experiment of the visualization system for 20 subjects. We made ten subjects the summary of liquor reviews using the visualization system, and made the remaining ten subjects the summary of them without the visualization system. Consequently, the usefulness of the visualization system was verified from the contents and the time for creation of the summary.

The eyes play a crucial role in defining the person's impression. However, there are still few studies of evaluation for the impressions of eye's form including the curve of bilateral upper eyelid. Thus, the aims of our study were to analyze and systematize the curve of bilateral upper eyelid using images of 100 Japanese subjects' eyes. Consequently, we classified the curves of males into 5 clusters and females into 6 clusters. Additionally, our study clarified the relationship between the impressions of masculine/feminine and the eye's form elements that consisted of the curves systematized the ratio of the width to height, etc. Concretely, we made 70 subjects to evaluate samples assembled with the eye's form elements by using design experiment. As a result of analysis of variance and multiple comparisons of main effects, we clarified that the bilateral upper eyelid were important form elements affecting the person's impression of masculine/feminine.

Creating beautiful curves of the forehead is considered to be the key to achieve optimal outcome of craniofacial plastic surgical reconstruction. However only subjective, or artistic techniques have been proposed in the past, therefore the outcomes of reconstruction seem to be entirely dependent on surgeon's ‘kansei’ or skills. Thus the aim our study were to analyze the curves of the forehead in 50 normal Japanese women, and classify the curves to create as a guide for total forehead reconstruction. To characterize the individual nature of the complex forehead curves, two key lines were abstracted from 3D data. Based on profile of curvature analysis, forehead curves were classified into 6 types in horizontal section line, and 2 types in meridian line. These classification were then used to develop curve templates as a guide for forehead construction. We applied these curve templates in complex craniofacial reconstruction and found that the outcome is very promising.

Pictograms attract attention in supporting the non-verbal communication and using of interface icon. The existing pictograms are basically painted in monochrome. It was clarified from existing studies that we could clear the mean of pictograms using color expression. However, there were few studies which analyzed the relation between comprehensibility and color express of pictograms and few useful design indexes when painting colors of the pictogram. Then, this study aims to analyze comprehensibility of the pictograms using color expression and to abstract the visual languages. The visual languages are visual elements that composing the design of pictograms communicating information visually. Concretely, we clarified typical colors and color combinations of morphological elements in 20 pictograms conveying meanings of verbs. On the basis of this result, we investigated the relation between comprehensibility and color expression of pictograms by experimental design method. And, we abstracted the visual languages for painting colors of the pictogram and verified its usefulness. As a result, we have clarified the usefulness of some visual languages. However, the comprehensibility of some pictograms was decreased by colorization, we considered characteristics of those color expression.
