A variety of trials selecting necessary and valuable information from rapidly increasing volume of data are made, and as one of them, data mining methods is an interest. This methodology is increasingly appzied to information management field which consists of efficient processing and systemizing increasing digital documents for user service. This article analyzes theoletical background and empirical case studies of data mining, and predicts the possibility of its application to information management area.

The purpose of this study is to propose a hierarchical user interfaces for browsing the knowledge structure of a single document. To generate the hierarchical knowledge structure, hierarchical term clustering and cluster representative term selection were performed with a single thesis in information science field, and the result was applied to design the interfaces which browse a single document hierarchically using multidimensional scaling. The interfaces can be applied to develop the user-friendly information retrieval system.

In this paper, a ontology-based keyword structuring method is proposed to represent the knowledge structure of scholarly documents and to make inferences from the semantic relationships holding among them. The characteristics of thesaurus as a knowledge organization system(KOS) for subject heading is critically reviewed from the information retrieval point of view. The domain concepts are identified and classified by analysis of the information activities occurring in a general research process based on scholarly sensemaking model. The ontological structure of keyword set is defined in terms of the semantic relationship of the canonical concepts which constitute scholarly documents such as journal articles. As a result, each ontologically structured keyword set of a document represents the knowledge structure of the corresponding document as semantic index. By means of the axioms and inference rules defined for information needs, users can efficiently explore the scholarly communication network built on the semantic relationship among documents in an analytic way based on the scholarly sensemaking model in oder to efficiently retrieve the relevant information for problem solving.

This study analyzed research output in dominant research areas of 19 national research institutions. Policy knowledge produced by the institutions during the past 5 years mainly concerned 10 policies dealing with economy and society issues. Similarities between the research subjects of the institutions were displayed by MDS mapping. The study also identified issue attention cycles of the 5 chosen policies and examined the correlation between the issue attention cycles and the yields of policy knowledge. The knowledge structure of each policy was mapped using co-word analysis and Ward's clustering. It was also found that the institutions performing research on similar subjects demonstrated citation preferences for each other.

이 논문에서는 한국의 수능 시험에 대응하는 일본 센터 시험의 세계사B 문제를 해결하는 시스템을 만들고 그 성능을 평가했다. 이 시스템은 문제의 각 보기의 신뢰도를 검증하여 어떤 보기가 참인지를 결정한다. 보기 검증을 위해 지식 베이스 기반, 정보 검색 기반, 시간적 제약 기반 검증을 사용하였다. 성능 평과 결과 6개년도 시험 중 5개 시험에서 통계적으로 의미 있는 결과를 얻었다. 이 시스템은 영어를 대상으로 하나, 한국어에도 존재하는 리소스를 사용했기 때문에 한국어에서도 같은 방법론을 적용할 수 있을 것으로 본다. 후속 연구로는 보기의 의미적 분석과 개체명 이외의 정보에 대한 검색이 필요하다.
