문서에 존재하는 중요한 개체를 인식하고 그것들 간의 관계를 식별하는 시맨틱 트리플 추출은 문헌 분석의 기반이 되는 중요한 작업이다. 본 논문에서는 특허 문헌에서 이러한 시맨틱 트리플을 추출하는 방법에 대해서 설명한다. 특허 문헌의 효과적인 자동 분석을 위하여 문장 내의 다양한 구문적 변형을 인식하여 하나의 정규화된 의미 형태로 표현해주는 술어-논항 구조 기반의 패턴을 사용하였고, 패턴의 자동화된 확장을 위하여 부트스트랩핑 방법을 적용하였다. 이러한 방법은 소규모의 시드 데이터를 활용하여 특정의미 관계를 갖는 패턴을 자동으로 확장하고 최종적으로는 유의미한 트리플을 추출하는 방법으로 다량의 이진 관계 집합을 처리해야 할 때 아주 유용한 방법이다. 시스템 적용을 통하여 특허 문헌에 적합한 38개의 연관관계 집합을 생성하였고, 32,608개의 유의미한 트리플을 추출하였다.

It constructs a database generally and service it does, to use a commercial business DBMS that manages information and to use a retrieval system that supports a search, it adopts the gearing method of the DBMS and information retrieval system. But like this method is inconvenient must operate the DBMS and information retrieval system with duplication to be, there is a weak point where the data management and processing become accomplished with duplication. It presents the DB construction and information search and the management model of the KRISTAL-2002 information retrieval and management system base for the scientific and technical information data management and processing from the dissertation which it sees.

According to the advancement of display devices, the multi-screen contents display environment is growing to be accepted for the display exhibition area. The objectives of this research are to find communications technology and to design an editor interface of contents delivery system for the larger and adaptive multi-display workspaces. The proposed system can find existence of display devices and get information without any additional tools like marker, and can recognize device layout with only web-cam and image processing technology. The multi-display contents delivery system is composed of devices with three roles; display device, editor device, and fixed server. The editor device which has the role of main control uses UPnP technology to find existence and receive information of display devices. extract appointed color in captured picture using a tracking library to recognize the physical layout of display devices. After the device information and physical layout of display devices are connected, the content delivery system allows the display contents to be sent to the corresponding display devices through WebSocket technology. Also the experimental results show the possibility of our device connection and layout recognition techniques can be utilized for the large spaced and adaptive multi-display applications.

To efficiently utilize an e-Science application service which is built on a grid computing environment, it is vital to develop technologies for integrating each e-Science application services into a workflow and for executing the workflow on a cooperative environment. In this paper, we analyze the requirements of e-AIRS system, one of the e-Science environment of aerospace research community. From the requirement analysis, we propose the required functionality and the architecture of e-Science workbench for effective utilization of e-Science services on cooperative environment.

Scholarly information service is compared with internet portal services for object of use, information attributes and target users. It is not popular service, so scholarly information service providers need to have distinguished marketing strategy. KISTI service development team has performed on-site training for end users in major customer institutions in 2008. This study shows the effect of scholarly information service on-site training and user's preference of service promotion in specialized information service field.

Recently, the cases of archiving for digital contents are being increased throughout the world. Owing to the characteristics of digital contents including the issues on volatile property and authenticity, preservation weakness, and aging in the reproductive tool, it requires special management for long-term preservation. A successful digital archiving seems to be possible in the stage-oriented practice through the cooperation of interested organizations based on the systematically established and stipulated policy. This is the basic study that was designed for the establishment of the policy on digital contents archiving in KISTI(Korea Institute of Science and Technology Information), which is a representative organization for the distribution of science and technology information. By investigating and analyzing the cases of overseas policies on digital contents archiving, it intended to understand the framework of digital archiving policy while suggesting measures on the macroscopic items that were included in the archiving policies through the interview conducted to expert groups.

Patent information has a great value of industrial information as well as technical information. However, Korean patent information loses the effectiveness by the lack of description rule and requires much additional efforts to use them in variety. In this paper, some examples of the studies on the problems in databases were introduced and patent application(from Jan. 2008 to Oct. 2008) data retrieved from information service system of KISTI(Korea Institute of Science and Technology Information) and KIPI(Korea Institute of Patent Information) was surveyed.

KISTI portal service is currently presenting the documents with many terminologies, so users can't find the results having their intention by using an umbrella query. In this paper, we suggest user oriented retrieval service that reflects query auto-complete, related-word suggestion and query expansion that uses nouns and relationships of U-WIN which is known as a semantic language resource. We intend to advance the retrieval satisfaction of current science & technology information service by using U-WIN's semantic information and improve the service environment that user can retrieve what they want quickly and exactly.
