A Study of the Behaviours in Searching Full-Text Databases- Subject Specialists vs. Professional Searchers -

전문데이터베이스의 탐색특성에 관한 연구 - 주제전문가와 탐색전문가 -

The primary purpose of this study is to verify the difference of behavioural characteristics between the subject specialists and professional searchers in searching full-text databases. The major findings and conclusions from this study are summarized as follows. Analyses of Search questions(the degree of understanding with search questions, the degree of difficulty in selecting terms, and the degree of expectation of search results), search processes(the number of search terms used, the number of Boolean operators and qualifiers used, the number of documents browsed and the search time(the connecting time, time to spend per one output document, time to spend per one relevant output document) and search results(the searching efficiency(the number of relevant documents, the ,recall ratio and the precision ratio), the search cost(the total search cost. the search cost per one output document and the search cost per one relevant output document) and the degree of satisfaction with search results) are significantly different between the subject specialists and professional searchers in searching full-text databases.

본 연구는 전문데이터베이스의 탐색에 있어서 주제전문가와 탐색전문가는 어떠한 특징적인 차이가 있는지를 밝히려 하였다. 이 연구를 통하여 얻어진 결론을 요약하면, 주제전문가와 탐색전문가는 전문데이터베이스의 탐색에, 있어서 탐색질문의 분석(탐색질문의 이해도. 탐색어 선정의 난이도, 탐색결과에 대한 기대수준), 탐색과정(탐색어수, 연산자 순 브라우징 문헌 순 접속시긴 출력문헌 건당 소요시긴 적합문헌 건당 소요시간), 탐색결과 (적합문헌수 재현율 정확율, 총 탐색비용 출력문헌 건당 소요비용, 적합문헌 건당 소요비용, 탐색결과에 대한 만족도)에 대하여 뚜렷한 차이를 나타내는 것으로 밝혀졌다.
