This study analyzed the collaborative process in time series by dismantling the edit log big data of Wikipedia Korea, a representative online collaboration community, from early 2002 to 2019. Analysis elements were extracted from the document edit records, formatted in standardized XML, and analyzed using Python and R. The ways of editors' contribution, the characteristics of data contents, and the trend of document creation were explained by the analysis. An active contribution of a small set of editors and a loose participation of the majority were revealed. In addition, sociocultural characteristics that appear in online communities were also found in Wikipedia Korea. A new, diverse set of external resources is necessary to sustain the collective intelligence. An effort to settle new editors into the wikipedia community and an openness through circulation structure to avoid the exclusiveness of the management group are suggested.

As the complexity of Web applications have increased significantly, the approach using frameworks such as Cocoon, Struts, JSF, is being suggested to develop Web applications more Quickly and efficiently. However, it Is difficult for beginners to write Apache Cocoon Sitemap files in XML. We implement a Cocoon Sitemap editor on the Java Servlet engine that allows beginners to write Cocoon Sitemap files more easily. Our system consists of three parts: Sitemap Main editor, Pipeline Viewer, and Sitemap Tracer. Sitemap Main editor support users to write BML configuration documents, so-called Sitemap file, that defines all the components pipelines, generators, and other configuration information for a Cocoon application. pipeline Viewer support users to catch the structure of Cocoon component pipelines by the medium of graphical interface. Sitemap Tracer have features to monitor of SAX events through Cocoon pipelines in a Sitemap file.

다양한 분야에서 중요하게 사용될 수 있는 뉴스 비디오 데이터베이스를 구축하기 위해서는 비디오 색인의 자동화에 관한 연구가 필연적이다. 본 논문에서는 뉴스 비디오 색인을 자동화하는 방법으로, 이전에 제안한 컷 추출 방법을 이용하였다. 컷에 의해 추출된 키 프레임에서 앵커 인식 알고리즘으로 앵커 프레임을 자동으로 추출하여 색인을 부여하는 방법으로 비디오 스트림에 대한 색인을 자동화하였다. 구성되는 색인 구조의 형태는 앵커 프레임들이 시간에 따른 사건의 연결이 되고, 앵커 프레임 내에서는 종속되는 키 프레임들을 중심으로 원형을 형성한다. 이들 각각을 논리적으로 통합하면 사용자의 관점에 따라 여러 가지 방법으로 브라우징되며, 사용자가 원하는 뉴스 비디오 씬들을 쉽게 선택하여 볼 수 있는 특징을 제공하는 장점을 부여한다. 또한, 색인화 된 비디오 스트림을 이용하면 자동적으로 비디오 편집을 수행 할 수 있는 비디오 저작도구의 기반을 제공할 수 있다.

오늘날 컴퓨터와 통신 기술의 발달로 시간과 공간의 제약 없이 공유된 가상 공간에서 작업을 하는 컴퓨터 지원 협동 시스템이 등장하고 있다. 그러나 그래픽 분야와 CAD시스템은 하드웨어와 응용 소프트웨어에 크게 의존하고 있는 실정이다. 여기에서 제안하는 협동 CAD시스템은 인터넷 망을 통하여 웹 상에서 플랫폼에 구애받지 않고 협동작업이 이루어지도록 하였고, VRML과 Java3D API를 이용하여 쉽게 도형을 생성하고 편집하여 전송하거나 출력 저장할 수 있도록 하며, 채팅을 통해 인터액티브 한 작업이 가능하게 하고 있다. 이 시스템은 클라이언트/서버 구조로 클라이언트는 자바 애플릿을 통해 웹 상에서 접근하고 서버는 자바 애플리케이션으로 접속을 통제하는 접속관리자, 작업 그룹의 동기화를 유지하며 공유작업공간을 확보하는 작업관리자, 그리고 3차원 도형 객체를 생성해 내는 솔리드 모델러로 이루어져 있다.

In this study, it was intended to present solution for learners to understand and utilize photogrammetry more easily using economic medium except expensive measuring equipment. For this, 3D point data was analysed by generating event to stereo image on monitor, and input to CAD system automatically. so, real time vector editing and drawing with coordinates measurement were possible. The system was verified, and the monitoring for real construction was performed. so, it is expected to be utilized as a practical use software in related fields.

Every conceptual temporal rat relationship can be described using one of seven relations (before, meets, overlaps, during, starts, finishes, and equals ). The conceptual representation provides an efficient means for our multimedia authoring system to automatically fill in the necessary timing details. We developed a multimedia Presentation authoring system that supports a mechanism for conceptually representing the temporal relations of different media. Among the many editors that make up our system, the temporal relation editor provides users with an intuitive mechanism for representing the conceptual flow of a presentation by simple and direct graphical manipulations. Our system is based on the SMIL(Synchronized Multimedia Integration Language). The conceptual temporal relation editor and other editors of our system exchange their information in real-time and automatically generate SMIL codes through the SMIL Object Manager. Our system uses TRN(Temporal Relation Network) as its internal multimedia presentation representation. The TRN corresponds exactly to the structure seen in the graphical representation of the presentation. A parallel relationship found in a TRN can be collapsed into a single synchronization block. This facilitates the determination of the playing time of each component and can be the basic unit for reusability of already prepared blocks of presentation code.

XML document repositary system(XDRS) should be able to manage vertical and horizontal versions of documents to store, update and manage XML documents without loss of information, However, most of existing XDRSs do not support a versioning method Although a few systems support versioning method. they only manage vertical versions of XML documents, While the vertical versioning preserves the update history of documents. the horizontal versioning branches a document to many other versions of documents so that users can easily create new documents from the original version and edit them to have different meanings. In this paper, we propose a new version numbering scheme to support both vertical and horizontal versioning efficiently. We also design a schema that supports versioning and preserves the paradigm of structure information.

Users of World Wide Web (Web) experience difficulties in the retrieval of pertinent information due to the increased information provided by Web sites and the complex structure of Web documents that are continuously created, deleted, restructured, and updated. Web providers' efforts to maintain their sites are tend to be less than that of site creation due to the expenses required for maintenance. If information of relationship among Web documents and their validity is provided to Web managers as well as Web developers, they can better serve users. In order to grasp the whole structure of a Web site and to verify the validity of hyperlinks, traversal and analysis of hyperlinks in a Web document are required to provide information for effective and efficient creation and maintenance of the Web. In this paper, we introduce a Web Editor specialized for Web maintenance. We emphasized on two aspects: first, the analysis of HTML Tags to extract hyperlink information and second, establishment of the relationship among hyperlinked documents, and verification of the validity of them.

This paper describes a multimedia synchronization model based on the MPEG-4(Moving Picture Expert Group) system. It defines and modifies new nodes for representing temporal relationships between media objects in the BIFS(Binary Format for Scene) of MPEG-4 system which Integrates, manages and transfers multimedia objects such as audio, video, image, etc. The relationships are represented by using a multimedia temporal model during the start, play and delay time interval. In addition, we illustrate a multimedia authoring system that includes the Interface used for defining the temporal relationships. Differently from several contentional tools generally appropriate for professional users who can edit the BIFS nodes of themselves, the system provides end-users with the function that can define the temporal relationships of multimedia objects directly in the interface.

As major industries become information -centered, business transactions and information -sharing processes are being computerized and automated, which ultimately re-defines electronic commercial transactions in a broader context. Business documents are the basic tools for corporate transactions. The use of business documents in electronic commercial transactions has increased markedly and this sphere is rapidly being extended to include information sharing between companies. XML(extensible Markup Language) was selected as the focus for this thesis. XML can help to make a complicated and data-rich document easy to share. The thesis proposes a business XML document editing system, comprised of a style document editor for business XM document structure, business documentation, and business document presentation, along with a business document transformation system which makes a transformation possible regardless of platform or using various corporate document standards.
