In general, Q&A system retrieves passages by matching terms of a question in order to find an answer to the question. However it is difficult for Q&A system to find a correct answer because too many passages are retrieved and matching using terms is not enough to rank them according to their relevancy to a question. To alleviate this problem, we introduce a topic for a sentence, and adopt it for ranking in Q&A system. We define a set of person-related topic class and a clue expression which can indicate a topic of a sentence. A topic classification system proposed in this paper can determine a target topic for an input sentence by using clue expressions, which are manually collected from a corpus. We explain an architecture of the topic classification system and evaluate the performance of the components of this system.

The purpose of this study is to review the current status of disseminating knowledge on Korean people by analyzing biographies for juvenile and general audiences with the subject term 'Korea' in WorldCat. Languages and topics of 15,007 bibliographic records and topic facets, biographees, and holding libraries in the U.S. of 487 biographies for juvenile audiences were analyzed. Major findings are as follows: 1) 30 English biographies are held by may libraries in the U.S. and the most popular subjects are Kim Il-song and Kim Jong-il, 2) 457 Korean biographies are not held by many libraries, and King Sejong and the General Yi Sun-sin are the most popular subjects, 3) many Korean biographies are picture books for the very young readers with the focus on Korean folklores and anecdotal biographies, and 4) there are some errors in topic facets, dispersion of biographees, and inaccurate holding lists of bibliographic records. Therefore, there seems to be little to read with an interest and promote the diffusion of knowledge on Korean people through libraries.

This study analyzed the methods for representing and linking personal information in the linked data of National Library of Korea and provided suggestions for expanding the scope of identifying and linking of the personal information. As a result, the personal information as a subject has been dealt with a concept, where the personal information as a contributor has been linked with a vocabulary of personal name. In addition, there have not been assured of including additional information except existing authority data in the process of building the linked data. Therefore, this study suggested that linking personal information as a subject and personal information as a contributor was essential for the quality of linked data. In addition, we proposed to provide additional information related to the person in linked data for expanding the scope of access points in information discovery.

This study examines the main characteristics and differences on people's page in selected four national dailies, such as Chosun Ilbo, Joongang Ilbo, Seoul Shinmum and Hankyoreh Shinmun. Both Chosun Ilbo and Joongang Ilbo are categorized as the conservatives; while Seoul Shinmum and Hankyoreh Shinmun as the progressive. This study has been done by applying methods of content analysis to reveal the differences in terms of people's occupations, types of reports, their philosophies, and standards of selecting people by the dailies for the people's pages. The results shows that the conservative newspapers are very similar to the progressive newspapers in terms of occupations and the types of reports, covering the people on people's pages. More specifically, both the conservative dailies and the progressive dailies report the people for whose jobs are related to both social and cultural works. However, the conservative newspapers have much more coverages than the progressive papers in terms of the publicity reporting on the people. The conservatives are also much more reports on the people who are eager to economic success than the progressive dailies; while the progressives papers have much coverages on those who are interesting in helping others than the conservatives papers. Finally, this study reveals that the conservative dailies mainly cover those who are in publicity activities and social elite groups, while the progressive newspapers are the social celebrities and persons of fame in society.

The humanoid creatures like Na'Vi in 'Avatar' remind the audience of a few actors' faces in the movie, enhance realism in film through combining CG and Live action which are related to the story. The design of face-recognizable humanoid creature is expected to be used in many ways; not only in film, but also in newest media. This research proposes to apply the main concept of Caricature which is 'exaggeration' of distinctive face elements from their prototypes for 'likeness' with the subjects. Also, it provides the idea of extracting the distinctive features of a face and combining the exaggerated subject as those features with an imaginary creature-other species, alien, etc. Finally, it proves the effectiveness of the design process with some experiments.

The subject heading is an elaborate access tool for subject browsing and searching in information retrieval environment. The purpose of this study is to suggest the applicable facets to subject headings in Korea. First, the concepts of subject and the definitions of facets were investigated in the literature review. Second, six cases including OCLC's FAST, PRECIS, "Thesaurus construction and use", CC $7^{th}$ edition, BC $2^{nd}$ Edition, and UDC $3^{rd}$ Edition were analyzed to focus on configuration of facets as case studies. Based on the results, twenty-two facets were proposed including Topical, Event, Geography, Chronology, Personal and Corporate Name, Title, Form, Genre, Language, and Person facets as 11 top facets. Also, Topical-Thing/Entity and Topical-Action/Status, Part, Kind, Property, Whole, Material, Patient, Product, By-Product and Agent facets as sub-facets of Topical facet.

This paper is focused on objective and meaning of its compilation through reviewing system, composition, method of description, and content of "Jwagyebudam". "Jwagyebudam" has all round form of a history and character book by recording via arranging figures from the end of 16th century to the middle of 18th century in a chronological order. Figure were not only assigned at close range by steretyping people into groups to a degree in it, but also recorded in a chronological order. In view of method of description, "Jwagyebudam" concentrated a theme by recording via separating different people associated from a figure and content of the same event by using the same method like 'Hogeonbeom(互見法)' shown in "Sagiyeoljeon(史記列傳)". In addition, it obtained effect to objectify evaluation of figures included. In a method of embodying figures, it has described concretely and in a three dimensions figures by recording anecdotes and poems associated with them via focusing on lifelong characteristic aspect of corresponding figures. In other words, "Jwagyebudam" can be called by biographies or character books, writings specialized in characters center among writings of method to weave freely experience. In a broad sense, it can be called a writing to cover a function of history book, poem and picture. This was located to a starting point of variation of inclusive and descriptive method.

This study analyzed the development and growth of folksonomy by examining tags associated with 40 bestsellers on LibraryThing.com in 6-month intervals. It was found that tag values do not decrease but grow in terms of quantity and quality. Accordingly, we examined the major significances of the tags and their potential utilization as an expression of subjects. Our findings were as follows. First, the motivations for tagging can be categorized into personal information for search purposes, self-fulfillment such as sense of achievement, display of emotion and sharing of one's experience with others, or an altruistic objective that emphasizes sociality with a desire that one's actions might provide social benefits. According to our analysis, 74.12% of tags had a social motivation. Second, the total number of tags and the frequency of usage increased with time. Third, the categories that showed a high increase in tag usage were dates of publication and reading, key words, main characters, and book reviews. Tags related to subjects had the highest ratio. Fourth, among Library of Congress Subject Headings (LCSH), multiple genres, key words and main characters were assigned to books, and specific key words and other properties were added as time progressed. There was also a slight increase in the number of tags consistent with LCSH. Fifth, we found that key tags could serve as a compilation of terms that reflects the knowledge base of the corresponding era. Thus, folksonomy should be continuously monitored for its quantitative and qualitative development of the tags to make improvements on its formative disadvantages, and identify internal semantic significance, be actively utilized in conjunction with taxonomy as a flexible compilation of terms that incorporate the history of a specific era.

본 연구의 주제는 정보의 관계를 사용자 중심으로 시각화하는 것이다. 생활속에서 제공되는 대부분의 정보들은 보이지 않는 연결성을 가지고 있다. 이런 정보들의 공통적인 특성 및 관계의 연구를 통해 정보의 중요도를 측정할 수 있고, 각 정보의 개체 간의 연결성이 형성되어 인접정보의 접근이 용이해진다. 특히 인간관계는 사회 연결망의 주된 관심사이며, 사회의 각 개체 간 관계를 분석하여 도식화하는 여러 방법론이 제시되어 있다. 이번 연구를 위하여 제한된 사회라고 볼 수 있는 그리스 신화를 소재로 선정하여 등장인물들 간의 관계를 파악하는데 사회연결망 이론을 적용하였다. 하지만 시각화 측면에서 볼 때 현재 제공되는 사회 연결망 분석 도구는 사용자를 고려한 디자인 부분이 배제되어 단순히 정보를 일방적으로 보여준다는 한계를 지니고 있다. 미톨로지아에서는 분석된 자료를 바탕으로 사용자가 정보를 파악하는데 좀더 효과적이고 용이한 시각적인 구성을 가질 수 있도록 시도했다. 사회 연결망 분석법으로 그리스 신화의 인물들이 가진 신분, 출현 빈도, 감정관계 등을 수치화하여 인물의 연결성을 분석하였다. 또한 정보와 사용자 간의 상호작용 기능을 제공함으로써 사용자의 이해도를 높였다. 기본 인터페이스는 인물노드에 쉽게 접근할 수 있도록 4 가지 분류에 의한 인덱스의 형태를 가지며, 인물 간의 세밀한 관계는 선택에 의한 줌-인(zoom in) 기능을 통해 볼 수 있다. 이는 기존의 필터링 기능과는 차별적인 요소로서 직접 관련된 정보 이외의 정보들은 시각적으로 제한되어 사용자가 인물 관계를 빠르고 직관적으로 파악할 수 있다. 미톨로지아는 개괄적인 관계를 보여주는 레이아웃과 부분적이며 상세한 정보를 파악하기에 적합한 인터랙션 방법을 제시한다.

Since sentences are the basic propositional units of text, their themes would be helpful for various tasks that require knowledge about the semantic content of text. Despite the importance of determining the theme of a sentence, however, few studies have investigated the problem of automatically assigning the theme to a sentence. Therefore, we propose a sentence theme allocation scheme based on the head-driven patterns of sentences in encyclopedia. In a serious of experiments using Dusan Dong-A encyclopedia, the proposed method outperformed the baseline of the theme allocation performance. The head-driven pattern 4, which is reconfigured based on the predicate, showed superior performance in the theme allocation with the average F-score of $98.96\%$ for the training data, and $88.57\%$ for the test data.
