The learning by computer games, is in the spotlight as an effective education method for the game generation. The educational games need to provide additionally an omniscient view of the learning as an objective viewpoint for storytelling of learning. The omniscient viewpoint needs good readability in real-time, and to provide systematically overall and detailed informations of learning. In this paper, we propose the visual learning map as the omniscient view for storytelling of learning. The proposed learning map is composed of the district map, the topic map, and the progress map for the omniscient view of the learning. The proposed learning map is represented by several visual diagrams for real-time readability. The proposed learning map can apply to all the educational games which provide the game minimaps.

Ontology specifies the knowledge in a specific domain and defines the concepts of knowledge and the relationships between concepts. It is possible to provide the service based on the semantic web through the ontology. Therefore, to specify and define the knowledge in a specific domain, it is required to generate the ontology which conceptualizes the knowledge. Accordingly, to search the information of potential customers for home-delivery marketing of post office, we design the specific domain to generate the ontology based on the semantic web in this paper. And we propose how to retrieve the information, using the generated ontology. We implement the data search robot which collects the information based on the generated ontology. Also, we confirm that the ontology and the search robot perform the information retrieval exactly.

Background in a novel is most important elements with characters and events, and means time, place and situation that characters appeared. Among the background, spatial background can help conveys topic of a novel. So, it may be helpful for choosing a novel that readers want to read. In this paper, we are targeting Korean historical novels. In case of English text, It can be recognize spatial background easily because it use upper and lower case and words used with the spatial information such as Bank, University and City. But, in case Korean text, it is difficult to recognize that spatial background because there is few information about usage of letter. In the previous studies, they use machine learning or dictionaries and rules to recognize about spatial information in text such as news and text messages. In this paper, we build a nation dictionaries that refer to information such as 'Korean history' and 'Google maps.' We Also propose a method for recognizing spatial background based on patterns of postposition in Korean sentences comparing to previous works. We are grasp using of postposition with spatial background because Korean characteristics. And we propose a method based on result of morpheme analyze and frequency in a novel text for raising accuracy about recognizing spatial background. The recognized spatial background can help readers to grasp the atmosphere of a novel and to understand the events and atmosphere through recognition of the spatial background of the scene that characters appeared.

A study of philosophy is a process that archive, reorganize and analyze the earlier works to discover new facts. Philosophy digital resources is necessary to research philosophy because they provide lots of electronic texts, philosophical information, forums, etc. In this paper, we introduce . our result of a research on philosophy digital resources existing in domestic or oversea web sites. We describe the problems which existing resources have and our solution to solve them. Also we provide a guideline to creating philosophy ontology based on topic maps which are data model of ontology. Our philosophy ontology defines hierarchy and associative relationships between philosophical knowledge and support retrieval and exploring of knowledge using semantic information.

ERP system is a fundamental system that is commonly adopted by most companies that intend to take part in e-business. However, few companies are running ERP systems successfully because of inaccuracy in data managed by ERP system. In this paper, we propose a model and the building process of item ontology which organize concepts describing all items managed by enterprises. In addition, we design and implement a system to create and manage item ontologies. We interface our system with a commercial ERP system, then install and run these systems on a manufacturing company. Our item ontologies and management system might help enterprises when they try to take part in e-business.

가상현실 기술은 3 차원 가상공간 및 물체를 시각화하는데 중점을 두고 있다. 이는 사용자가 3 차원으로 데이터를 충분히 활용하지 못하고, 시각자료로만 사용하게 되는 요인이 된다. 이를 보완하기 위해 시각 정보뿐만 아니라 구조 및 관계에 대한 정보까지도 효과적으로 활용 할 수 있는 연구가 필요하다. 따라서 본 연구에서는 외형뿐만 아니라 내부적인 구조와 관계에도 의미를 부여하기 위하여 3 차원 건축물에 XML 기반의 토픽맵을 적용하였다. 전통 건축물의 공포 부분을 모델링하고, 각각의 객체가 사용자에 의해 조작이 가능하도록 하였으며, 객체들의 구조와 연결관계를 분석하고, 정의된 구조 및 관계를 토대로 토픽맵을 작성하였다. 작성된 토픽맵은 모델링 데이터에 적용 가능하도록 DOM 을 이용하여 변환하였다. 이 연구를 통해 아무리 복잡한 구조물이라도 그에 대한 구조 정보를 쉽게 파악할 수 있었고, 계층적 연결 관계도 쉽게 파악 할 수 있었다.

Text detection has been a popular research topic in the field of computer vision. It is difficult for prevalent text detection algorithms to avoid the dependence on datasets. To overcome this problem, we proposed a novel unsupervised text detection algorithm inspired by bootstrap learning. Firstly, the text candidate in a novel form of superpixel is proposed to improve the text recall rate by image segmentation. Secondly, we propose a unique text sample selection model (TSSM) to extract text samples from the current image and eliminate database dependency. Specifically, to improve the precision of samples, we combine maximally stable extremal regions (MSERs) and the saliency map to generate sample reference maps with a double threshold scheme. Finally, a multiple kernel boosting method is developed to generate a strong text classifier by combining multiple single kernel SVMs based on the samples selected from TSSM. Experimental results on standard datasets demonstrate that our text detection method is robust to complex backgrounds and multilingual text and shows stable performance on different standard datasets.

As the importance of an historical area is getting increased in these days, the reconstruction of an bell chamber in Namhansansung has significant historial, educational and cultural meaning. The purpose of this study, as a study on an bell chamber in Namhansansung, is to assume an original location of the bell chamber and identify the size and shape of the original bell chamber through literature study, site inspection, and analysis on old maps. In addition, this study could provide useful information when new bell chamber is constructed. According to the literature study, site inspections(5 times) and analysis on old maps, the original bell chamber is assumed to locate near current Oroji tea house at the rotary, where was in the area of Hanggung. With regard to the traffic system, it is assume that there was an old road along with the current local road No.342 connecting the South Gate with North Gate and a Y or T shape intersection connecting the site of old bell chamber with the north. In addition, there was a government office street from the old bell chamber to Hanggung. The shape of old bell chamber is assumed to have Paljak or Woojingak roof. Samo roof was not found in all the five maps. Regarding the direction of bell chamber, three maps indicate that it faces the East and two maps show that it faces the South. Therefore, it is assumed that the length and width of the roof have similar size. However, a new bell chamber should face the East, which is the same direction with Hanggung. As there is a record which states that a bell in the Cheonheoungsa, Seonggeosan, Cheonan was used as a Namhansansung's bell when the Cheonheoungsa was closed, this study suggests that new Namansansung's bell should be built, considering histroical value and artistry of Cheonheoungsa's bell. This study is a basic research for the reconstruction of Namhansansung in 2009. However, as reconstruction of historical assets should be based on thorough historical evidences. Therefore, more detail researches by a indicator analysis are left for the topic of future studies.

The web as global network includes text document, video, sound, etc and connects each distributed information using link Through development of web, it accumulates abundant information and the main is text based documents. Most of user use the web to retrieve information what they want. So, numerous researches have progressed to retrieve the text documents using the many methods, such as probability, statistics, vector similarity, Bayesian, and so on. These researches however, could not consider both the subject and the semantics of documents. As a result user have to find by their hand again. Especially, it is more hard to find the korean document because the researches of korean document classification is insufficient. So, to overcome the previous problems, we propose the korean document classification method for semantic retrieval. This method firstly, extracts TF value and RV value of concepts that is included in document, and maps into U-WIN that is korean vocabulary dictionary to select the topic of document. This method is possible to classify the document semantically and showed the efficiency through experiment.

This study tried to suggest the revitalization plans for specialized libraries by referring to various issues regarding specialized libraries in the sense that the issue of specialized libraries can soon become an opportunity for the development of specialized libraries. Through literature analysis, problems and issues related to specialized libraries were derived, and the perception of librarians was investigated through surveys. The policy directions presented based on the results are as follows. First, the 'Library Development Plan' should strengthen the part related to the specialized library development plan. Second, topic maps for specialized libraries in Korea are needed.(Second, the topic map for specialized libraries in Korea is needed.) Third, it is also necessary to operate to configure multiple councils based on the distinction between the specialized library. Fourth, an analysis of the duties of specialized library librarians should be made. Fifth, professional information services that specialized libraries can perform need to be developed. Sixth, among the information resources owned by specialized libraries, it is necessary to find ways to establish and jointly utilize information resources that are valuable and shareable as national resources. Seventh, specialized libraries should allow every library to participate in library evaluation, and make improvement plans for specialized libraries based on the collected data. Eighth, it is also necessary to publish a collection of best practices for specialized libraries.
