본 연구에서는 저자명 모호성 해소를 위해 토픽모델링 기법을 사용하여 저자명을 식별 하였다. 기존의 토픽모델링은 용어 자질만을 고려하였지만 본 연구에서는 제 3의 메타데이터 자질을 활용하여 ACT(Author-Conference Topic Model) 모델과 DMR(Dirichlet-multinomial Regression) 토픽모델링을 대상으로 저자명 식별 성능을 평가, 비교하였다. 또한 수작업으로 저자 식별 작업을 한 데이터셋을 기반으로 저자 당 논문 수와 토픽 수에 차이를 두고 연구를 진행하였다. 그 결과 저자명 식별에 있어 ACT 모델보다 DMR 토픽모델링의 성능이 더 우수한 것을 알 수 있었다.

In this paper, we analyzed the research trend of Library and Information Science field in Korea using science and technology authority data which has been constructed by KISTI. The authority data is a set of data given a unique identifier to identify a unique object for the authors, affiliations and journals of domestic and international academic paper that published in Korea or written by Korean authors. We examined collaborating patterns, authors and institutional productivity through analyzing the 5 domestic LIS journals published from 1997 to 2013.

The purpose of this study is to investigate knowledge structure of knowledge organization research area in Korea. The study employed content analysis and network analysis to analyze degree centrality, betweenness, and eigenvector as well as frequency of words. It also analyzes research articles published during the period of 2000-2001. The study can be summarized that the network of keywords of knowledge organization researches is compact and complicated. Cataloging and classification play important roles in the network, and metadata and ontology becomes focal areas in knowledge organization. On the other hand, networks of authorships and authors are broad and fragmented. Collaboration is not active enough.

This study tried to explore the relation between research networks(coauthor network, author co-citation network, author bibliographic coupling network) and research performance of Records and Archives Management study in Korea. For the analysis, three basic types of network centrality and three indicators of research performance are used. The summary of this study is as follows: Firstly, there are relations between three centralities and three indicators of research performance in the coauthor network. Secondly, there are relations between betweenness centrality and research performance in the author co-citation/author bibliographic coupling networks. Thirdly, there are relations between three centralities in the each research network. Fourthly, there are not high relations between all centralities of the three research networks.

대부분 국내에서 발행되는 과학기술 분야의 논문에는 저자 키워드가 포함되어 있다. 이 키워드는 논문을 이해를 돕고 온라인 검색에 유용하게 활용되고 있다. 특히 많은 논문에서 키워드를 영문과 국문을 동시에 부여하도록 하고 있어 과학기술 용어로서의 가치도 있다. 일정 기간 국내에서 발행되는 논문으로부터 저자 키워드들을 추출하여 다양한 각도에서 부여 키워드의 현황을 분석하였다. 결론으로 바람직한 키워드 부여의 방향을 제시한다.

The purpose of this study is to measure the extent of collaboration by comparing team size patterns of Korean LIS journals with international LIS journals. For the sample dataset, the top 30 ranked international journals in the field of LIS were selected using the Scimago Journal Rank (SJR), and 4 Korean LIS journals were selected for the years between 2010-2016. The size of the team who authored Korean journal articles were collected from the RISS database, while the size of team who authored international journal articles from the top LIS journals were collected using the Scopus database. The result of this study shows that the most common team size ranged from one member team to three member teams. Overall, the collaborative team size in international journals was higher than Korean journals. In particular, one member team was the most common team size in Korean journals, whereas two members team was most common in the international journals. At the subject level, the most common team size was one team member in the subject area of Library Related, while the most common team size was three team members in the subject area of Science/Engineering. The result of this study suggests that within LIS, the size of teams may vary considerably due to differences in subject areas.

In this study, we proposed the FRAD concept model of authority data schema for author, organization and journal titles included in the academic papers. Academic information includes author names, affiliations, publishers, journals and conferences. They are used as access points, and there are multiple relationships among these entities. It is expected that the use of authority data for academic information based on FRAD conceptual model could improve more accurate retrieval of information, systematic management of academic information, and various forms of knowledge representation. In this study, our entity-relationship authority data will be linked to the document, and included the several properties and relationship to identify the object.

For the construction of accurate scientific citation information, author disambiguation should be primarily resolved. This study proposes a method that utilizes URI(Uniform Resource Identifier) to create precise author citation networks. The adoption of URIs for representing authors and papers in this study enables us to maintain the integrity of constantly changing citation information and to guarantee the accessibility to the right literature. In experiments, we extracted 2,872 author-centric citation relation pairs from recent major IT-related proceedings written in Korean. From those, 135 citation network groups were discovered. The findings of this study are expected to be applied to a variety of researcher network services and scientific information portal services.
