본 연구의 목적은 LDA 토픽모델링 결과와 BERTopic 토픽모델링 결과를 합성하는 방법론인 Augmented and Extended Topics(AET)를 제안하고, 이를 사용해 문헌정보학 분야의 연구주제를 분석하는 데 있다. AET의 실제 적용결과를 확인하기 위해 2001년 1월부터 2021년 10월까지의 Web of Science 내 문헌정보학 학술지 85종에 게재된 학술논문 서지 데이터 55,442건을 분석하였다. AET는 서로 다른 토픽모델링 결과의 관계를 WORD2VEC 기반 코사인 유사도 매트릭스로 구축하고, 매트릭스 내 의미적 관계가 유효한 범위 내에서 매트릭스 재정렬 및 분할 과정을 반복해 증강토픽(Augmented Topics, 이하 AT)을 추출한 뒤, 나머지 영역에서 코사인 유사도 평균값 순위와 BERTopic 토픽 규모 순위에 대한 조화평균을 통해 확장토픽(Extended Topics, 이하 ET)을 결정한다. 최적 표준으로 도출된 LDA 토픽모델링 결과와 AET 결과를 비교한 결과, AT는 LDA 토픽모델링 토픽을 한층 더 구체화하고 세분화하였으며 ET는 유효한 토픽을 발견하였다. AT(Augmented Topics)의 성능은 LDA 이상이었으며 ET(Extended Topics)는 일부 경우를 제외하고 대부분 LDA와 유사한 수준의 성능을 나타내었다.

Abstract

The purpose of this study is to propose AET (Augmented and Extended Topics), a novel method of synthesizing both LDA and BERTopic results, and to analyze the recently published LIS articles as an experimental approach. To achieve the purpose of this study, 55,442 abstracts from 85 LIS journals within the WoS database, which spans from January 2001 to October 2021, were analyzed. AET first constructs a WORD2VEC-based cosine similarity matrix between LDA and BERTopic results, extracts AT (Augmented Topics) by repeating the matrix reordering and segmentation procedures as long as their semantic relations are still valid, and finally determines ET (Extended Topics) by removing any LDA related residual subtopics from the matrix and ordering the rest of them by (BERTopic topic size rank, Inverse cosine similarity rank). AET, by comparing with the baseline LDA result, shows that AT has effectively concretized the original LDA topic model and ET has discovered new meaningful topics that LDA didn’t. When it comes to the qualitative performance evaluation, AT performs better than LDA while ET shows similar performances except in a few cases.

다수의 연구에서 정보추구 과정상 불 확신성(Uncertainty) 의 중요성이 지적되었지만, 실제 정보검색시스템을 이용한 탐색과정에서 이용자들의 불 확신성에 대한 연구는 많지 않았다. 본 연구는 실제로 정보를 추구하는 이용자들의 웹 검색어 선정과정에서의 불 확신성 인식을 조사하여, 정보탐색 과정에서의 다양한 불 확신성 유형을 식별하였다. 불 확신성 유형에 입각하여 발견된 불 확신성의 주요 원인(Origins)은 정보검색시스템 및 서비스 발전을 위한 시사점을 제시하여준다.

Abstract

While numerous studies have suggested the significance of uncertainty during the process of information-seeking, less research has investigated user uncertainty in the actual search process using a real system. This study investigated user perceptions of uncertainty in the process of the selection of Web search terms in the real information-seeking process. The subjects at the doctoral or post-doctoral level were limited to the discipline of science in order to understand user perceptions in this field. The findings revealed various dimensions, types, and incidents of uncertainty. The typology of uncertainty facilitated an understanding of the subjects' information-seeking context by identifying various aspects of the context that constituted the subjects’ uncertainty. The identification of two principal origins of uncertainty based on the different types of uncertainty generated implications to improve information systems and services.

Abstract

This study examined two characteristics of library and information science (LIS) journals in Korea through analysis of journal coupling with common authors. This study also illustrated the trend of Korean LIS research in the recent decade. The notable change is that record management and archival studies settle in LIS domain as a major research area. We introduced two indicators, Publishing Preference Index (PPI) and Researcher Attraction Index (RAI), based on the degree of common authors among journals. Both indicators revealed notable changes in author coupling, including reversal of PPIs in some journals, which can be interpreted as proof of changes in their author groups. The RAI analysis, which measured the degree of journals’ attractiveness to Korean LIS researchers and author sharing between two journals, illustrated the journals’ states in a domain; this result can help find both an isolated journal and strongly bonded journals in the specific domain. Journal coupling with common authors introduced in this study proved to be an effective investigative method for illustrating journals’ states in a specified domain as well as a multidisciplinary area.

Abstract

The goal of this paper is to explore the field of Computer and Information Science with the aid of text mining techniques by mining Computer and Information Science related conference data available in DBLP (Digital Bibliography & Library Project). Although studies based on bibliometric analysis are most prevalent in investigating dynamics of a research field, we attempt to understand dynamics of the field by utilizing Latent Dirichlet Allocation (LDA)-based multinomial topic modeling. For this study, we collect 236,170 documents from 353 conferences related to Computer and Information Science in DBLP. We aim to include conferences in the field of Computer and Information Science as broad as possible. We analyze topic modeling results along with datasets collected over the period of 2000 to 2011 including top authors per topic and top conferences per topic. We identify the following four different patterns in topic trends in the field of computer and information science during this period: growing (network related topics), shrinking (AI and data mining related topics), continuing (web, text mining information retrieval and database related topics), and fluctuating pattern (HCI, information system and multimedia system related topics).

Abstract

The domain of digital libraries is one of interdisciplinary fields since it contains various aspects of digital libraries. The main findings of digital library interdisciplinarity have been discussed in terms of contents, management and infrastructural technologies within the field of library and information science. The purpose of this study is to identify and widen the interdisciplinary structure of digital library domain by analyzing the collaborations from different disciplines. With 1,394 research articles of digital libraries from 1997 to 2010, the analysis of collaborations of authors from various disciplines was conducted. The results identified that three subject areas of authors such as Information science and library science, Computer science and Engineering were found as the centers to collaborate with various disciplines. In addition, sub-domains of digital library were recognized in terms of core digital library area, natural science area, medical related area and biology and medical area. The findings of this study depict the domain of digital libraries as a variety of subject areas since digital library domain is characterized with both research and practices.

Abstract

A large and reliable citation database is necessary to identify and analyze citation behavior of Korean researchers in science and technology. Korea Institute of Science and Technology Information (KISTI) built the Korea Science Citation Database (KSCD), and have provided Korea Science Citation Index (KSCI) and Korea Journal Citation Reports (KJCR) services. In this article, citing behavior of Korean scientists on Korean journals was examined by using the KSCD that covers 459 Korean core journals. This research dealt with (1) statistical numeric information of journals in KSCD, (2) analysis of document types cited, (3) ratio of domestic to international documents cited and ratio of citing different disciplines, (4) analysis on immediacy index, peak time, and half-life of cited documents, and (5) analysis on impact of journals based on KJCR citation indicators. From this research, we could find the immediacy citation rate (average 2.36%), peak-time (average 1.7 years) and half-life (average 5.2 years) of cited journals in Korea. We also found that the average journal self-citation rate is more than 50% in every field. In sum, citing behavior of Korean scientists on Korean journals was comprehensively identified from this research.
