  • 최근 전자상거래의 상업성이 부각되면서 많은 기업들과 개인사업자들이 독자적인 웹서버를 구축하고 자사의 상품 또는 기업에 대한 광고 내용을 인터넷을 통해 서비스를 하고 있다. 그러나 소비자에게 홍보가 부족하고, 상품의 종류와 정보의 부족으로 외면을 당하고 있는 웹사이트들이 많이 있다. 본 논문에서는 이러한 기업들의 카탈로그를 수집하여 재구성한 후, 한 사이트에서 여러 기업의 상품을 검색할 수 있도록 하여 소비자의 접근과, 각 기업의 상거래 사이트를 활성화 할 수 있는 메타 전자 쇼핑몰 개발에 관해 기술한다. 본 시스템의 특징은 로봇이 자동으로 데이터 베이스를 구축하여 소비자가 쉽게 검색 할 수 있도록 주제어 검색과 디렉토리 검색 인터페이스를 구성을 가지고 있다는 점이다.

  • The purpose of this study is to identify users behavioral characteristics for using the online catalog opened in May 1996 at Duksung Women's University Library. 278 student users were surveyed from October 4th to 8th in 1996. Major findings are as follows. 1. Most users$(87.4\%)$ prefer the online catalog to the card catalog and regard the online catalog easy to use$(89.6\%)$ 2. $(65.8\%)$ of users are active users who frequently use the online catalog at least 10 times or more per semester. 3. $10.4\%$ of users feel the online catalog difficult because they do not know how to use it. 4. Most users prefer the menu search mode among menu, command and fill-in-blank search modes offered by DISCOVER. The most preferred access points are the title for known-item search and subject headings for subject search. 5. User's attitude toward the online catalog is very favorable$(83.5\%)$, however, the search success rate is rather low $(77.0\%)$ compared to that of the card catalog $(87.0\%)$ 6. The title and author are regarded easy to use among access points offered by DISCOVER. Classification numbers and call numbers are the least easy access points to use. 7. Since users show lack of knowledge of how to use the online catalog, education and training programs on the online catalog use for users are needed. 8. Users showed different search patterns for pursuing different search goals. The most preferred access points are the title for known-item search and subject headings for subject search. These search behaviors are different from those in using the card for both the known-item search and subject search was the title.

  • 기존에 보안을 위해 개발되어온 취약점 검색도구는 최근 들어 불법침입을 위한 도구로 이용되고 있으며 이제는 웹사이트에서도 쉽게 취약점 검색도구와 악의적인 프로그램들을 구할 수 있게 되었다. 이에 대한 방안으로 현재 침입차단 기능을 가지는 방화벽과 침입탐지 기능을 가지는 침입탐지시스템이 개발되어 왔다. 방화벽은 외부 네트워크와 내부 네트워크 사이에 위치하여 인증된 트래픽만을 허용함으로써 보안을 유지할 수 있으나 사전에 미리 IP 주소나 포트 등을 등록하여 해당 IP 주소와 포트로부터의 접근을 허용하거나 막는 정적인 방법이었다. 또한 침입탐지시스템은 침입탐지에 대한 룰을 내장하여 칩입행동을 실시간으로 탐지하는 기능을 가지지만 그에 대한 대응이 실시간 차단이 아니라 공격자와 관리자에게 경고메일을 보내는 수준이므로 침입탐지 이후에 생기는 불법행동에 대한 커다란 위험이 따른다 본 논문에서는 그에 대한 해절 방안으로 방화벽의 침입차단 기능과 침입탐지시스템의 실시간 침입탐지 기능을 갖춘 실시간 침입탐지 및 차단을 위한 시스템을 제안한다.

  • The purpose of this study is to design the meta search system and the curriculum-oriented directory system for youth in science and to prove the efficiency of the systems through evaluating the usability. To attain the purpose of this study, both of the quality and quantity research method were used and questionnaire, interview. observation, thinking aloud method were used to collect a data for research. The result of this study is that the meta search system supplying convenient information use environment about the distributed information sources has higher usability than the individual search system. And the curriculum-oriented directory system supplying accessibility related with the class has higher usability than the subject-oriented directory system.

  • 최근 멀티미디어 데이터로부터 내용에 대한 정보를 추출하여 데이터베이스에 저장하고 내용에 기반한 질의를 수행하도록 하는 내용 기반 검색 시스템이 중요한 핵심 기술로 대두되고 있다. 본 논문에서는 내용 기반 멀티미디어 검색 시스템인 COSMIC(Content Based Multimedia Information Processor)의 설계 및 구현에 관하여 기술한다. COSMIC은 대용량 이미지 데이터로부터 자동으로 추출된 시각적 특징 데이터들을 다차원 점접근 방법(Point Access Method)인 HG-트리를 이용하여 색인하고 예제 이미지와 사용자가 그린 스케치에 의한 시각적 질의를 제공한다. 또한 COSMIC은 비디오 데이터로부터 추출된 다양한 의미 정보를 이용하여 의미 질의를 제공한다. COSMIC의 유효성을 입증하기 위해서 다양한 시각적 질의와 이미 질의를 이용한 실험을 수행하였다.

  • In this study, a query language was developed to supplement the information retrieval and model regeneration in the case of Industry Foundation Classes (IFC)-based civil infrastructure information models. First, the IFC objects to represent the structural components, entities to manage the related properties, and relationships to connect with the mentioned elements were analyzed in a point of information flow. The results confirmed that the end-users could have problems with access and comprehend the properties and its relationships in the IFC file. Second, the IfcPropertySet-focused query method and applicable stand-alone module were proposed referring to the previous Building Information Model Query Language (BimQL). The availabilities of the proposed method were examined using the rail and sleeper information models through information retrieval and model regeneration. The most important advantage of the proposed approach is the IFC-based information retrievals that can guarantee the interoperability between software packages.

  • In these days the online full-text database are increasing, but conventional full-text information retrieval system has been proved with high recall ratio and low precision ratio. One of the disadvantages of full-text IR system is that it is not designed to reflect the user's information need it is due to the fact that full-text IR system has been designed based on physical and logical structure of document without considering the content of document. Therefore, the purpose of the study examined feasibility of document content structure in full-text IR system by resolving such disadvantages of conventional system. 180 Journal articles have been analyzed to find common structure of document content and finally general model of the structure of journal articles were developed. The result shows that have relation to between user's cogntive schema structure, user's information need and contents structure of document. Thus it is concluded that full-text IR system need to be designed by using document content structure in order to meet user's information need more effectively.

  • Metadata and folksonomy are two main approaches in representing, organizing, and retrieving resources in the current information environment. Many researches have conducted studies to combine of metadata and folksonomy in order to utilize the strengths of both approaches. This research proposed an approach to utilize both metadata and folksonomy in representing resources by using microcontents. Microcontents in this research is a conceptual structure that reflects dynamic characteristics of folksonomy and the structure of metadata. By connecting folksonomy with metadata through this microcontents structure, both approaches can maximize their strengths and minimize their weaknesses in representing, organizing, and retrieving resources.

  • The tremendous growth in electronic journals made it clear that access would be one of the biggest issues confronting libraries seeking to adopt them. While users must be given the freedom to move seamlessly between electronic and paper journals, the most of university libraries in Korea have not provided a single point access to these yet. This study offers opportunities to improve the convenience which permits integrated access to the thousands of electronic and paper ones. It is suggested that the integrated catalog can be an appropriate solution that allows the one-stop shopping approach to library's entire collection.

  • Recently, distribution of record via web and coefficient of utilization are increase. so, Archival information service using website becomes essential part of record center. The main point of archival information service by website is making record information retrieval easy. It has need of matching user's request and representation of record resources correctly to making archival information retrieval easy. Archivist and record manager have used various information representation tools from taxonomy to recent thesaurus, still, the accuracy of information retrieval has not solved. This study constructed record retrieval system based on Topic Map by modeling record resources which focusing on description metadata of the records to improve this problem. The target user of the system is general web users and its range is limited to the president related sources in the National Archives Portal Service. The procedure is as follows; 1) Design an ontology model for archival information service based on topic map which focusing on description metadata of the records. 2) Buildpractical record retrieval system with topic map that received information source list, which extracted from the National Archives Portal Service, by editor. 3) Check and assess features of record retrieval system based on topic map through user interface. Through the practice, relevance navigation to other record sources by semantic inference of description metadata is confirmed. And also, records could be built up as knowledge with result of scattered archival sources.
