Abstract

As a way of identifying users' image needs for improved effectiveness of image search, there have been recent research approaches to examine contextual factors in image needs with multiple perspectives. In this line of research, this study examined a total of 70 unsuccessful image searches for the purpose of investigating users' image needs. In order to achieve the purpose of this study, in particular, the characteristics of image needs, contextual factors on image needs, and image queries were investigated. The findings of this study demonstrated that information needs from the failed image searches are categorized primarily into specific and general/nameable categories. More importantly, these information needs are embedded with multiple contextual factors, primarily, task purpose and use purpose. With an analysis of detailed use purposes for image, illustration use was found most in this data set. For query analysis, the type of unique/refined image query was revealed primarily. As the results of this study were found similar to the findings of previous studies, it is possible to characterize the image needs from the failed image searches. In addition, the findings of this study are expected to be useful to the design and service of image retrieval.

이용자의 이미지요구 규명은 이미지 정보 서비스와 시스템 효율성 증진을 위해 필수적인 요소이다. 최근에는 이미지요구 분석에 있어서 다양한 맥락 요소를 접목하여 다층적인 관점에서 이미지요구를 규명하고자 하는 시도들이 있다. 본 연구는 이러한 최근 연구의 흐름과 맥을 같이 하며, 이용자의 이미지요구를 규명하기 위해서 총 70건의 이미지 검색 실패 사례를 분석하였다. 그 결과 이미지 검색 실패 사례에 나타난 이미지요구는 구체적, 일반적/지칭 가능한 요구가 주를 이루는 것으로 나타났으며, 이러한 결과는 선행 연구와 유사한 것으로써 검색 실패한 이미지요구의 특성으로 볼 수 있다. 또한 이미지요구에 배태된 맥락요소에 관한 분석결과를 살펴보면, 업무/과제의 목표와 이용목적에 관련된 맥락요소가 주를 이루는 것으로 나타났다. 이용목적의 맥락을 보다 상세하게 살펴보면, 일러스트레이션 이용목적이 높은 비중으로 나타났다. 이미지 검색 질의 특성은 고유어와 정련어의 쌍으로 분석할 때 고유어/정련어, 비고유어/정련어, 고유어/비정련어, 고유어/정련어 쌍 순서로 비중을 차지하는 것으로 나타났다. 검색 실패 이미지요구의 특성으로써 구체적이거나 일반적/지칭 가능한 요구이며 이는 비고유어/비정련어 쌍을 특징적으로 살펴볼 수 있다. 맥락의 관점에서는 목표 중심이며 일러스트레이션 이용목적이 주된 맥락 요소임을 알 수 있다. 이러한 결과는 이미지 검색 시스템이나 서비스 개선을 위한 시사점이 될 수 있다.
