Abstract

The purpose of this study is to investigate whether Google Scholar (GS) can substitute Web of Science (WoS) for those who don't have access to the subscription-based indexing service and if users feel GS is useful for scholarly information. To achieve the research purpose, the study evaluates both quantitative and qualitative aspects of the two databases. The major results through statistical analysis show that GS indexes much more records and citations for LIS journals than WoS(p < .01), but users' feedback about GS is not better than those about WoS.

Google Scholar(GS)는 인용색인 데이터베이스 측면에서 나름 부족한 부분은 있으나 무료라는 점과 대규모 크기의 데이터를 갖춘 이용자 중심의 자료라는 점에서 많은 이용자에 의해 이용되고 있다. 본 연구는 Google Scholar의 학술정보 검색을 겨냥한 정보 유용성 진단을 목적으로 기존의 통제어휘의 기반을 둔 인용색인 데이터베이스인 Web of Science(WoS)와 대비하여 비교분석한다. 실증적 정보 유용성 평가를 위해 두 가지 분석으로 진행되었다; 첫째는 문헌정보학 분야의 학술지를 중심으로 두 데이터베이스의 검색결과와 인용문헌의 수의 차이가 있는가를 정량 분석했다. 두 번째는 WoS 접근성이 떨어지는 이용자의 경우 GS가 WoS의 대체 정보원으로 기능할 수 있는지에 대해 이용자를 대상으로 정성분석을 실시했다. 실증 데이터 분석을 통해 얻어진 연구 결과는 정량평가에서 GS는 WoS에 대비해서 통계적으로도 유의한 높은 검색결과와 인용문헌수의 차이를 보여 대체 정보원의 기능이 가능한 반면, 정성평가에서는 이용자들은 GS와 WoS의 질적 차이를 크게 느끼지 못하는 것으로 나타나 대체기능을 확인할 수 없는 것으로 나타났다.
