최근 Web 2.0 발달과 더불어 블로그나 온라인 카페 등 웹 상의 사용자가 개인적인 정보를 자유롭게 개제할 수 있도록 하는 인터넷서비스가 증가하면서, 이 사용자들 간의 관계에 초점을 맞춘 소셜 네트워크 분양의 연구가 활발히 이루어지고 있다. 하지만 많은 소셜 네트워크 서비스가 정보자원을 컴퓨터가 처리할 수 있는 의미적인 정보로 표현하고 있지 않기 때문에 서로 다른 도메인 간에 공유와 재사용이 어렵고, 사회적 개체들 간의 관계가 명확하게 정의되어 있지 않아 소셜 네트워크 분석에 어려움이 있다. 본 논문에서는 가상 커뮤니티 사용자들이 업로드 한 사진 데이터를 이용한 시맨틱 웹 기반의 소셜 네트워크 분석 시스템을 제안한다. 온톨로지를 기반으로 사진에서 추출된 얼굴 개체와의 관계와 이미 인맥 관계를 형성하고 있는 사람들의 정보적 연결성을 명확하게 정의하고 도메인 규칙을 활용하여 의미 있는 사회적 연결 관계를 추론한다. 이를 그래프로 시각화하여 사용자에게 제공함으로써 온라인 상에서 형성된 커뮤니티 내에서 효율적인 소셜 네트워크 분석을 도모하고 이를 기반으로 다양한 응용 분야에 활용하는 방법을 모색한다.

오늘날 인터넷 사용자들은 블로그나 뉴스 등의 매체에서 트랙백을 사용해 자신의 의견을 보다 자유롭게 나타낸다. 그러나 이러한 자유로움을 악용해 트랙백 스팸을 유발하여 네트워크의 자원을 낭비하고 방문자들에게 잘못된 정보를 전달해 해당 포스트의 신뢰를 떨어뜨린다. 트랙백 스팸은 유명한 포스트와 연계하여 자신의 포스트로 사용자들을 유도하는 특징을 가지기 때문에 일반적인 웹 스팸을 탐지하는 기술을 적용하기 어렵다. 따라서 본 논문에서는 자신이 작성한 글이 다른 사람의 글과 관련이 있다고 생각하여 다른사람의 글에 자신의 글을 링크시키는 트랙백의 특성을 이용하여 원본 페이지와 트랙백 페이지 그리고 트랙백 페이지의 아웃링크 내용상의 유사도와 동시 출현(co-occurrence) 정보를 이용하여 트랙백 스팸을 처리하고자 한다.

Since a 'Well-being' theme had become an issue in 90's, everyone now care about their health more than ever. Besides, IT has been developed so tremendously that we have various ways to collect up-to-dated information through the internet. In this thesis paper, I propose a web site called 'Calory&Diet' that provides customized information on diet. With its user friendly menu and feedback information, the proposed web site can be a good advisor for people who want to be healthy.

최근 Blog/SNS가 새로운 커뮤니케이션 도구로 정착이 되면서 지위 고하를 막론하고 많은 사람들이 자신의 의견을 인터넷 상에 표현을 하고 있다. 이러한 많은 의견들은 다른 사람들과 의견을 교환하는 역할도 하고 있으나 여기에 신뢰할 수 없는 부정확한 정보 또한 다수 포함 되어 있다. 본 논문에서는 Blog/SNS의 익명의 사용자 직업을 추측하여 이용자로 하여금 이러한 부정확한 정보를 판단할 수 있는 하나의 수단과 이용의 판단에 근거를 제시한다. 이러한 방법을 통해 사용자는 무수한 정보들 속에서 신뢰성 있는 정보와 신뢰성이 없는 정보를 보다 정확하게 판단 할 수 있을 것이다.

인터넷 환경의 변화와 함께 많은 서비스가 오픈 API 형태로 지원되면서 이들을 결합하고 이용하는 웹 기반의 클라이언트 프로그램이 모바일 환경의 주요한 어플리케이션 형태로 등장했다. 또한 차세대 웹 폼 언어인 XForms는 간편하고 효과적인 UI기술 언어로서 알려져 있으며, 다양한 모달리티를 지원할 수 있고 장치 독립성을 제공할 수 있어 모바일 장치에 더 적합하다. 본 논문에서는 오픈 API를 지원하는 XFroms 페이지를 설계하고, XForms의 특징을 살려 성능 및 표현력을 개선한 브라우저를 구현하였다. 또한 오픈 API를 사용하는 모바일 블로그 서비스를 XForms기반 오픈 API 페이지들을 통해 작성함으로써 제안된 시스템의 표현력과 유연성을 증명하였다.

The purpose of this study was to look for useful implications in its next application or similar planning by assessing visitors' recognition of International Garden Exposition Suncheon Bay Korea 2013. To do this, blogs acknowledged as powerful communication media in modern information society were used. After searching for blogs related to International Garden Exposition Suncheon Bay Korea in the portal site ranked first in the domestic market share, this study classified 300 cases. This study was able to grasp the consciousness as bloggers gave descriptions of information and impressions and experiences of spaces without making any adjustments. The survey results are as follows: First, Dutch gardens were the most preferred, followed by Korean gardens, Chinese gardens and French gardens; in general, visitors were not satisfied with the national gardens. Inquiry is needed into the method of determining diverse cultural identity rather than a sample garden type through blogs delivering regret regarding the world gardens. Second, the survey results showed that the level of awareness of designers' gardens was low. This study judges that more emphasis should be placed on their roles as places speaking for the original purpose of the garden exposition which introduces gardening art and design through experimental design. Third, it was understood that many bloggers were deeply impressed by ephemeral landscapes like the change in landscape consequent on the elapse of time, distinctive atmosphere, and detailed-landscapes. These aspects are important landscape elements, and those elements should be addressed with weight in a subsequent study. Fourth, the most impressive places are 'Suncheon Lake Garden' and 'Bridge of Dreams', which are establishing themselves as icons of International Garden Exposition Suncheon Bay Korea 2013. However, relatively, public attitude towards the world gardens and designers' gardens are weak. Fifth, bloggers were providing a variety of information like transportation, events schedules, ticket purchasing & prices, discount information, etc. Ticket price was commented on the most, and most of the bloggers thought ticket prices were 'expensive'. This study understands such a phenomenon as a result of the general population's non-establishment of the perception that it's proper to view gardens at visitors' own expense. Generally, bloggers expressed satisfaction with International Garden Exposition Suncheon Bay Korea 2013, but with criticism as well. Their criticism included disappointing matters, to be improved upon and wishes without any distortion, providing meaningful implications deserving reference for similar cases. In this context, a blogger could be called a citizen-reviewer while a blog could be referred to as 'a field of informal discourse' for the public. As a research method of this study, blogs are difficult to interpret as they are subjective and personal, and have limited data analysis through their quantifications; however, blogs as methods of recognition survey are channels for varied, concrete and detailed awareness which are hard to grasp through a questionnaire survey or interviews. This study judges that such an aspect of a blog could be a useful means of grasping and reflecting upon visitors' attitude in future studies.

The social media data and the broadcasting data related to onion as well as agri-food consumer panel data were collected and investigated if the amount of money spent to purchase onion in year 2014 when onion price plunged latest were correlated with the frequencies of onion-related keywords in the social media data and the broadcasting programs because onion price in year 2018 is expected to plunge due to overproduction and there has been needs to analyze impacts of social media and broadcasting program on onion purchase in the previous similar events, and identify potential factors that can promote onion consumption in advance. What we identified from our study include a) broadcasting news programs mentioning words "onion," were correlated with onion purchase with 3 - 6 weeks in advance; b) broadcasting entertainment programs mentioning words "onion and health," were correlated with onion purchase with 11 weeks in advance; c) blog mentioning words "onion and efficacy," were correlated with onion purchase with 5 weeks in advance. Our study provided a case on how social media and broadcasting programs could be analyzed for their effects on consumer purchase behavior using big data collection and analysis in the field of agriculture. We propose to use the findings from the study may be applied to promote onion consumption.

Recently, the web 2.0 services which appear by exponential extension of the Internet can be expressed with the changes in the quality of structural evolution and in the quantity of increasing users. The structural base is in user participational architecture, the web 2.0 services such as Blog, UCC, SNS(Social Networking Service), Mash-up, Long tail, etc. play a important role in organization of web, and grouping and searching of user participational data in web 2.0 is broadly used by folksonomy. Folksonomy is a new form that categorizes by tags, not classic taxonomy skill. it is made by user participation. Searching based on tag is now done by a simple text or a tag cloud method. But searching to consider and express the relations among each tags is imperfect yet. Thus, this paper provides the relational searching based on tags using the relational graph of tags. It should improve the trust of the searching and provide the convenience of the searching.
