In this study, we investigated the information users' needs and information seeking behavior in the field of science and technology. We found that the science and technology researchers most frequently needed information while conducting the research & development related tasks and drafting research papers. The researchers attributed the main sources of research ideas to be the communication among colleagues and the literature review. The researchers's most preferred information sources were digital libraries, web search engines, and academic information portal. In conclusion, the science and technology researchers regarded the online use of electronic materials as the primary source of information. We hope that this investigation reported herein to be the foundation for developing user-centered information services for the science and technology discipline.
Digital Library Evaluation Criteria: What do Users Want?
Iris Xie,Soohyung Joo,Krystyna K. Matusiak 한국비블리아학회 2014 한국비블리아학회지 Vol.25 No.1
Criteria for evaluating digital libraries have been suggested in prior studies, but limited research has been done to understand users’ perceptions of evaluation criteria. This study investigates users’ opinions of the importance of digital library evaluation criteria. Thirty user participants, including 10 faculty members and 20 students, were recruited from five universities across the United States. They were asked to rate the importance of evaluation criteria in eight dimensions (e.g. collections, information organization, context, etc.). The results demonstrate that users care about evaluation criteria related to the use and quality of collection and services rather than the operation of digital libraries. The findings of this study are relevant to the development of user-centered digital libraries and associated evaluation frameworks through the incorporation of unique users’ needs and preferences.
디지털 도서관 평가기준: 이용자들이 원하는 것은 무엇인가?
Xie, Iris,Joo, Soohyung,Matusiak, Krystyna K. Korean Biblia Society for Library and Information 2014 한국비블리아학회지 Vol.25 No.1
기존의 여러 연구들에서 디지털 도서관 평가를 위한 기준들이 제시되어 왔으나, 대부분의 연구에서 평가기준에 대한 이용자 관점을 이해하려는 노력이 부족하였다. 본 연구는 디지털 도서관 평가 기준들에 대한 이용자들의 의견을 미국 내 5개 대학교에서 10명의 교수 이용자와 20명의 학생 이용자에게 설문을 통해 직접 조사하였다. 설문 참여자들은 본 연구진에 의해 제시된 8개 영역 (장서, 정보조직, 맥락 등) 내 평가 기준들의 중요성에 대해 7점 척도로 응답하였다. 설문의 결과는 이용자들이 장서의 이용과 품질, 서비스와 관련된 항목들을 도서관 운영항목에 비해 상대적으로 더 중요하게 생각하고 있었음을 보여주었다. 본 연구의 결과는 이용자 중심의 디지털 도서관 개발과 관련하여 이용자의 요구와 선호를 반영하는 도서관 평가체계 구축에 도움이 될 것이다.

본 연구는 이미지 기반 디지털 도서관의 이용자 검색 패턴을 효과적으로 분석하기 위해 이용자 검색 로그 데이터를 분석하였다. 기술 통계와 네트워크 분석 방법을 사용하여 한 달간 수집한 트랜잭션 로그 데이터를 분석하였다. 연구 결과는 이용자들이 특정 주제 내에서 검색 결과 보기와 이미지 아이템 평가를 반복적으로 수행하고 있음을 밝혀내었다. 본 연구는 이미지 자료 검색의 로그 분석을 위해 복합적 데이터 분석 방법을 이용하였다는 점에 의의가 있다. Server transaction logs containing complete click-through data from a digital library of primarily image-based documents were analyzed to better understand user search session behavior. One month of data was analyzed using descriptive statistics and network analysis methods. The findings reveal iterative search behaviors centered on result views and evaluation and topical areas of focus for the search sessions. The study is novel in its combined analytical techniques and use of click-through data for image collections.
