본 연구는 연구문헌의 지식구조를 반영하는 의미기반 지식조직체계의 실험적 모형을 제시하는 것을 목적으로 한다. 이를 위해 한국연구재단의 기초학문자료센터에 대한 사례분석을 하였다. 기초학문자료센터 연구성과물 DB와 학술용어 DR의 개념클래스 및 인스턴스를 대상으로 연구문헌의 지식구조를 파악하였으며, 기초학문자료센터 시스템의 학술적 이해형성 기능을 분석하였다. 또한 연구문헌의 지식구조와 색인어의 관계를 분석하였다. 이러한 분석을 통해 지식구조와 색인어의 관계구조, 26개의 연구문헌 지식구조 공리 및 11개의 의미관계 추론규칙으로 구성되는 온톨로지 모형, 즉 연구문헌의 지식구조와 그 의미관계에 의한 실험적 지식조직체계 모형을 제시하였다.

Abstract

The purpose of this paper is to suggest a pilot model of knowledge organizing system which reflects the knowledge structure of research papers, using a case analysis on the “Korean Research Memory” of the National Research Foundation of Korea. In this paper, knowledge structure of the research papers in humanities and social science is described and the function of the “Korean Research Memory” for scholarly sense-making is analysed. In order to suggest the pilot model of the knowledge organizing system, the study also analysed the relation between indexed keyword and knowledge structure of research papers in the Korean Research Memory. As a result, this paper suggests 24 axioms and 11 inference rules for an ontology based on semantic relation of the knowledge structure.

Abstract

Since the 1990s, informetrics has grown in popularity among information scientists. Today it is a general discipline that comprises all kinds of metrics, including bibliometrics and scientometrics. To illustrate the dynamic progress of this field, this study aims to identify the structure and infrastructure of the informetrics literature using statistical and profiling methods. Informetrics literature was obtained from the Web of Knowledge for the years 2001-2010. The selected articles contain least one of these keywords: ‘informetrics’, ‘bibliometrics’, ‘scientometrics’, ‘webometrics’, and ‘citation analysis.’ Noteworthy publication patterns of major countries were identified by a statistical method. Intellectual structure analysis shows major research areas, authors, and journals.

Abstract

This study constructed an ontology targeting journal articles and evaluated its performance. Also, the performance of a triple structure ontology was compared with the knowledge base of an inverted index file designed for a simple keyword search engine. The coverage was three years of articles published in the Journal of the Korean Society for Information Management from 2007 to 2009. Protégé was used to construct an ontology, whilst utilizing an inverted index file to compare performance. The concept ontology was manually established, and the bibliography ontology was automatically constructed to produce an OWL concept ontology and an OWL bibliography ontology, respectively. This study compared the performance of the knowledge base of the ontology, using the Jena search engine with the performance of an inverted index file using the Lucene search engine. As a result, The Lucene showed higher precision rate, but Jena showed higher recall rate.

본 연구에서는 KMS의 지속적 사용에 영향을 미치는 요인을 분석하기 위해 KMS 품질, 지각된 사용 용이성과 지각된 유용성, 태도 및 KMS의 지속적 사용 간의 구조적 관계를 실증적으로 분석하고자 하였다. 이를 위해 본 연구는 경찰공무원들을 대상으로 한 설문조사를 통해 실증분석을 시도하였다. 가설검증 결과, 외부요인인 KMS 품질은 지각된 사용 용이성과 지각된 유용성에 유의미한 긍정적 영향을 미치고, 지각된 사용 용이성은 지각된 유용성에 긍정적인 영향을 미치는 것으로 검증되었다. 그리고 KMS에 대한 사용자의 지각된 사용 용이성과 지각된 유용성 모두 KMS 태도에 긍정적인 영향을 미치고, 태도요인을 매개로 KMS 사용행위에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 분석결과를 토대로 본 연구에서는 KMS의 지속적인 수용과정을 설명하고, 그 함의를 제시하였다.

Abstract

The purpose of this study is to examine the causal relationships among knowledge management system(KMS) quality, perceived ease of use, perceived usefulness, attitude, and continuance use of KMS. The results of data analysis by structured equation model(SEM) indicate that KMS quality significantly influences individual's perceived ease of use and perceived usefulness. Perceived ease of use affects individual's perceived usefulness on KMS. Individual's perceived ease of use and perceived usefulness affect on the creation of a positive attitude, and attitude affects continuance use of KMS. Based on the results, theoretical and practical implications of this study are discussed.
