Social media is considered a valuable platform for gathering and analyzing the collective and subconscious opinions of people in Internet and mobile environments, where they express, explicitly and implicitly, their daily preferences for brands and products. Extracting and tracking the various attitudes and concerns that people express through social media could enable us to categorize brands and decipher individuals' cognitive decision-making structure in their choice of brands. We investigate the cognitive network structure of consumers by building an inter-category map through the mining of big data. In so doing, we create an improved online recommendation model. Building on economic sociology theory, we suggest a framework for revealing collective preference by analyzing the patterns of brand names that users frequently mention in the online public sphere. We expect that our study will be useful for those conducting theoretical research on digital marketing strategies and doing practical work on branding strategies.

본 연구는 제품 디자인 프로세스중 아이디어나 디자인의 가능성에 대하여 탐색하는 부분을 중심으로 디자인 목표가 명확하게 정해지지 않은 상황하에서 1. 시각적으로 형태발상 지원시스템을 구축하여 디자이너에게 형태발상 능력의 한계를 극복할 수 있도록 지원하고, 2. 또한 사용자 참여적 형태발상 시스템으로서 웹 상에서 사용자들의 요구에 실시간으로 다이나믹하게 이미지를 생성해주고 사용자들의 선호도를 분석하여 선호도가 높은 이미지에 대한 정보를 디자이너에게 제공하는 즉 디자이너가 사용자들의 의견을 수렴할 수 있도록 하고, 3. 선호도가 낮은 이미지들은 누락시키고 지속적으로 새로운 이미지 조합을 업데이트하여 사용자의 형태 및 칼라에 대한 선호추세를 파악하여 미래에 선호될 수 있는 칼라와 이미지를 생성할 수 있도록 하였다. 이는 제품 디자인 개발 프로세스 중 아이디어발상 또는 형태 발상 지원에 대한 한 방식으로 그 효과가 있으리라 기대된다.

In recent times, studies sentiment analysis are being actively conducted by implementing natural language processing technologies for analyzing subjective data such as opinions and attitudes of users expressed on the Web, blogs, and social networking services (SNSs). Conventionally, to classify the sentiments in texts, most studies determine positive/negative/neutral sentiments by assigning polarity values for sentiment vocabulary using sentiment lexicons. However, in this study, sentiments are classified based on Thayer's model, which is psychologically defined, unlike the polarity classification used in opinion mining. In this paper, as a method for classifying the sentiments, sentiment categories are proposed by extracting sentiment keywords for major sentiments by using hashtags, which are essential elements of Instagram. By applying sentiment categories to user posts, sentiments can be determined through the similarity measurement between the sentiment adjective candidates and the sentiment keywords. The test results of the proposed method show that the average accuracy rate for all the sentiment categories was 90.7%, which indicates good performance. If a sentiment classification system with a large capacity is prepared using the proposed method, then it is expected that sentiment analysis in various fields will be possible, such as for determining social phenomena through SNS.

일관된 온/오프 아이덴티티 관리를 통해 양방향 커뮤니케이션을 강화하고 상호작용을 촉진하는 SNS의 본질과는 다르게 타인의 의견을 일방적으로 수용하는 수동적인 이용행태가 강화되고 있으며 표현의 자유를 즐기기 위해 페이스북을 익명 또는 가명으로 사용하는 사람들이 증가하는 경향을 보인다. 이처럼 변형적으로 나타나는 이용행태를 설명하기 위해 본 연구는 자존감, 실명사용, 의사표현과 같은 심리적·행태적 변인을 포함한 통합모형을 제시하고자 하였다. 연구결과 자존감이 실명사용과 자기노출에 영향을 주는 것으로 나타났으며, 실명사용자가 자신에 대해 더 많은 정보를 노출함에 따라 관계에 대한 만족도와 지속이용의도가 증가하는 결과를 보였다.

Multimedia systems present information by various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. Among many multimedia applications, the multimedia information retrieval systems commercialized in the forms of multimedia encyclopedia CD-ROMs, benefited from various media for their ability to present information in an efficient and complete way. But using several media, on the other hand, may cause end users' confusion and furthermore, poorly designed user interface often exacerbates the situation. In this study, the multimedia systems were studied from the standpoint of usability. The conceptual framework of the user interface of the multimedia system was newly defined. And 100 initial variables for user interface design of general multimedia systems were suggested through literature survey and expert opinions based upon the framework developed. Among various application areas, the multimedia information retrieval systems were chosen for investigation, and 36 variables particularly relevant to user interface of the multimedia information retrieval systems were selected. According to the sequential research strategy, the variables that were considered to be most important were finally selected through a screening stage. A part of selected variables were verified through a human factors experiment as the first step of sequential research. Based upon the result of the experiment, guidelines for user interface design were provided. For future study, the variables remained will be Investigated and the study will expand to another application areas.

By statistics in August, 2007, currently Korean motors registration number broke through 16 million units. The demand of motors is being increased as time goes on and the demand of parking lot within apartment complex is increased together. Therefore, it is inevitable to expand underground parking lots. Underground parking lots have relatively weaker environment than the ground and physical/psychological problems as distance far away from the main building, fear for vehicle damage and crimes, impure air, darkness and closed feeling take place. Underground parking lots also occupy a lot of area ratio within apartment complex and have a lot of effects on other facilities. Therefore, underground parking lots are neglected for all that underground parking lots have deep relations with satisfaction for public space within apartment complex. Accordingly, the purpose of the study is to make reference materials when underground parking lots are planned by grasping satisfaction of underground parking lots through inhabitants'mental survey and surveying preferential location and requirements of parking lots.

Purpose: This study was conducted to analyze web sites that provide child-care information and to provide a proper model for child-care web sites. Method: The evaluation tool with 23 items including purpose, contents, timeliness and reliability, interaction, and function was developed and modified. Quantitative analyses of 48 web sites, which were selected using popular search engines, were done. Result: 1) The aim of the web site was clearly shown for 24 sites (63.2%) and 17 sites (44.7%) provided the information for judging whether the informant was an expert. 2) Most web sites provided information on feeding, nutrition, and common health problems, and 11 sites provided information on care of problem behavior, but only 6 sites provided information on mother-infant interaction. 3) Timely information was provided on 21 sites, however none of the sites provided information sources. 4) Methods for contact the authors were found for 31 sites (81.6%) and 19 sites (50%) had active bulletin boards to receive opinions from users. 5) There were 32 sites where information could be found by clicking less than 3 times. Conclusion: We suggest that the evaluation criteria for child-care web sites used in this study is a tool that can be used to evaluate web sites with consistency, but there is a need for further study to develop standardization of the evaluating tool.

Social media enables customers to share their views, opinions and experiences as product reviews. These product reviews facilitate customers in buying quality products. Due to the significance of online reviews, fake reviews, commonly known as spam reviews are generated to mislead the potential customers in decision-making. To cater this issue, review spam detection has become an active research area. Existing studies carried out for review spam detection have exploited feature engineering approach; however limited number of features are considered. This paper proposes a Feature-Centric Model for Review Spam Detection (FMRSD) to detect spam reviews. The proposed model examines a wide range of feature sets including ratings, sentiments, content, and users. The experimentation reveals that the proposed technique outperforms the baseline and provides better results.
