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

Our limited understanding of real-life music information queries is an impediment to developing music information retrieval (MIR) systems that meet the needs of real users. This study aims to contribute to developing a theorized understanding of how people seek music information by an empirical investigation of real-life queries, in particular, focusing on the accuracy of user-provided information and users' uncertainty expressions. This study found that much of users' information is inaccurate; users made various syntactic and semantic errors in providing this information. Despite these inaccuracies and uncertainties, many queries were successful in eliciting correct answers. A theory from pragmatics is suggested as a partial explanation for the unexpected success of inaccurate queries.
