Abstract

The ability of the searcher to express their information problem to an information retrieval system is fundamental to the retrieval process. Query by visual example is the principal query paradigm for expressing queries in a content-based image retrieval environment yet there is little empirical evidence to support its efficacy in facilitating query formulation. The aim of this research was to investigate the usability of the query by colour method in supporting a range of information problems in order to contribute to the gap in knowledge regarding the relationship between searchers’ information problems and the query methods required to support efficient and effective visual query formulation. The results strongly suggest that the query method does not support visual query formulation and that there is a significant mismatch between the searchers information problems and the expressive power of the retrieval paradigm.

개인의 정보활용능력은 단기적으로는 현안 문제를 해결하고 장기적으로는 평생학습을 가능하게 해줌으로써 개인의 경쟁력에 많은 영향을 미칠 수 있다. 본 연구에서는 중요성이 부각되고 있는 정보활용능력이 개인의 성과와 상관관계를 가지는지를 대학생 집단을 대상으로 검증해 보았다. 개인의 성과 지표로는 실험집단이 대학생인 점을 고려하여 학업성취도인 평점평균을 채택하였다. 검증결과 정보활용능력(information literacy)에 대한 자기효능감(self-efficacy)과 학업성취도간에는 상관관계가 있음을 확인하였다. 또한 이러한 상관관계는 지속되는 것을 확인할 수 있었다. 이 연구를 통해 정보활용능력이 개인의 성과에 영향을 미친다는 것을 확인하였고 이는 정보활용능력 관련 교과의 개설에 대한 당위성을 제공할 수 있을 것이다.

Abstract

Information literacy of the individuals affects their competitive capability significantly by providing problem solving skills in the short run, and by enabling life-long learning in the long run. This study examines if information literacy capacity has any relationship with individuals' achievement level through the experiment with college student subject group. As evidences for individual achievement level, we adopted GPA's(grade point average) of students. As a result, it was confirmed that information literacy and academic achievements has positive relationship. Additionally, it has been found that this relationship has a tendency of sustaining for a significant period. These experiment results would serve as a rationale for providing information literacy courses in the academic curriculum.
