Title: Search strategies for image retrieval in the field of journalism
Abstract: People engage in multiple types of information-seeking strategies within an information-seeking episode. Very little is known about how end users develop and revise their search strategies. The objective of this study is to investigate search strategies made by end-users when searching for image information. A strategy refers to an approach that an information seeker adopts when dealing with a particular problem. Users' search strategies addressed in this study focus on querying, searching, and relevance decision-making stages. In the querying stage, characteristics of users' queries were examined to see what strategies are employed. In the searching stage, users' search moves and tactics to find relevant image information were analyzed. In the relevance decision-making stage, users' criteria and the usefulness of textual information of images for judging relevant images were identified. The study involves 30 photo editors, including 15 non-news and news photo editors respectively, using the AP Photo Archive database to retrieve specific, general, and subjective photos. Data were collected through think-aloud protocols, transaction logs and post-search interviews and questionnaires. Content analysis and quantitative methods were used to analyze the verbal, transaction and questionnaire data.
