오늘날, 웹서비스를 이용한 정보 검색을 하기 위해서는 UDDI 레지스트리의 전문적인 지식이 필요하다. 즉 웹 서비스를 명세하기 위해 사용된 카테고리와 이에 대한 값, 이름 등을 사전에 알고 있어야 한다. 그러나 일반 사용자들은 이러한 사전지식을 충분히 알고 있지 못하면 웹서비스에 대한 정보 검색을 쉽게 할 수 없다. 그러므로 일반 사용자들을 위해 웹서비스에 대한 점보를 카테고리에 맞게 분류하여 검색을 용이하게 할 수가 있다. 따라서 본 논문에서는 보다 효율적으로 웹서비스 정보를 분류하기 위해서 유전자 알고리즘과 신경망을 이용한 클러스터링 기법을 제안하는데 목적이 있다.

The purpose of this study is to examine how online knowledge-based search service is being used by students in science education. Reviewing information and summarizing data are important parts in scientific inquiry. As more and more information is available online, how to review and summarize online information for scientific inquiry also becomes an issue. In this study, we examined one of the popular online knowledge-based search services to see what kinds of information in secondary school chemistry are mostly sought and how reliable those information could be. The result indicated that users mostly seek scientific explanations and problem solving but about 30% of provided information appeared to be incorrect. It implicates that it is necessary to pay attention for teaching students how to obtain, evaluate, and communicate online information in science education to enhance students' ability for scientific inquiry.

One of the key factors in knowledge based economy is knowledge and information. Accordingly, public service policy for related knowledge and information is well equipped in Korea. However, policy has rarely been evaluated. This study analyzes usage and satisfaction of knowledge information service policy among broadcasting and video industry employees. Results shows low in usage as well as satisfaction among employees. Reliability of the service is relatively high, comparing to timeliness and usability. The fact that most respondents individually pay their efforts to collect and analyze information and knowledge means high need for them. This study recommends, instead of providing complete fixed data, to provide means to acquire knowledge, market oriented data to improve the effectiveness of the policy.

The present study attempted to test the effects of using external knowledge services on corporate management performance among SMEs. A survey of SMEs that had used external knowledge services was conducted for the analysis. The findings are as follows. First, regarding government-supported knowledge services for SMEs, knowledge service expert groups' competencies and government's support policies had positive effects on the quality of knowledge services. In particular, the knowledge service expert groups' competencies had more significant effects on the quality of knowledge services than the government's support policies. Second, the quality of knowledge services had significantly positive effects on management performance, whilst confidence-related knowledge service quality factors exerted significant effects on enhancing the relationship with customers and the informationization of knowledge. These findings have the following implication and meaning. The present findings indicate that the government's policy to foster and lay the foundation for knowledge service industry should be furthered, e. g. knowledge service supports for individual companies including knowledge service support projects and systems for SMEs and institutional supports for knowledge service companies and expert groups. In sum, this study is meaningful in that it suggests an effective and efficient policy direction for government's knowledge service provision projects.

지식관리시스템의 지식 분류 체계가 지식맵이며 이 지식맵을 이용하여 지식 서비스가 제공된다. 그러나 현재의 지식맵은 비표준적인 지식 네트웍 구조와 정적인 분류체계라는 문제를 가진다. 문제 해결 방법은 지식맵에 온틀로지를 적용해서 표준성, 의미 기반의 지식 네트웍 구조. 동적인 지식분류, 자동화된 지식서비스를 제공하는 새로운 개념의 지식맵을 구현하는 것이다. 본 논문에서는 토픽맵 모델을 기반으로 온톨로지를 생성, 저장, 검색하는 효율적인 온톨로지 관리 시스템인 K-Box를 구현하였다. K-Box는 온톨로지 관리를 위한 기본적인 기능들을 제공하며, 이질적인 저장소들을 일관된 인터페이스로 접근할 수 있도록 함으로써 저장 장치 독립성을 제공하였다. 또한, 저장 관리되는 모든 온톨로지들의 무결성을 보장하기 위한 새로운 기법과 사용자 관심을 중심으로 한 온톨로지 검색 지원을 위한 방법을 제안하였다. 마지막으로, 우리는 여러 온톨로지들을 적용해 봄으로써 K-Box 시스템이 효율적으로 사용 가능함을 확인하였다.

This study suggests evaluation criteria for the web-based question-answer databases provided by major Korean search portals. In particular, this study suggests evaluation criteria for the relevance of question titles, entire questions, and answer's. The evaluation criteria for the qualify of answers are also developed. Based on these criteria. evaluation of documents from Naver Knowledge-in are performed. The results of this study can be implemented to the development of test collection of question-answer databases. The implications for system designers and web content providers are discussed.

In this study, we propose an ontology based knowledge service system for efficient and sustainable sports events management with information and communication technology. For delivering personalized information and knowledge which relate on sports event operation and management, we analyze the core operations and suggest structure of sport event life-cycle process. Also, we design ontology based knowledge service as proposed in this study to apply on a golf tournament event management system.

CDS 서비스는 검증한 임상가이드라인과 프로토콜을 임상 실무에 적용함으로써 의료의 질을 향상시키고, 비용을 절감할 수 있는 방법이다. CDS 서비스를 실무에 구현하기 위해서는 검증한 지식과 이를 실행할 수 있는 지식엔진이 필수적인 구현 컴포넌트이다. 본 논문에서는 지식의 상호운용성을 보장하는 임상가이드라인 모델링 방법으로 SAGE라는 의료지식표현 기법을 선택하고, SAGE 지식을 기존 엔진과 연계할 수 있는 방법으로 변환 방법을 제안하였다. 또한 변환을 통한 기존 지식엔진 활용의 가능성을 검증하기 위하여 변환의 정확성을 검증하였다.

The importance of the creation, diffusion and utilization of the knowledge and information has been magnified at the 21st century of knowledge and information society. If the utilization level of the web site of the national-level R&D information system is enhanced, the duplication of the researches as well as overlapped R&D investment could be greatly reduced. In this regards, this study aims to identify the factors which affect customer value and intention of continued usage for the national science & technology information services (NTIS & NDSL). The empirical research results show that information service quality have a significant influence on the continuous usage intention of science & technology information service. Customer value, as well, influence the continued usage intention as a mediating variable. In addition, the situational factors of information use by itself shows a significant effect on customer value, but it does not moderating the relationship between information service quality and customer value. After a description of research result, we discussed implications and limit of the study as well as future study direction.
