傳統上，圖書館、博物館、美術館和檔案館是提供大量圖像的機構，包含繪畫、文物和文史資料等館藏；隨著網際網路的發展，圖像資源可以透過多元的管道取得和使用，圖像搜尋引擎、社群媒體和資料庫都是目前已經發展出的一些圖像檢索工具。在目前的圖像檢索系統中，圖像資訊很大程度上依賴索引者的創建或是自動化產生，然而，圖像具有別於文字資訊的特點，圖像中含有不同層次的視覺內容，一個關鍵字可以讓人聯想到許多圖像，一張圖像也可以讓人聯想到多樣的詞彙來描述，若是這些文字描述未能正確表達圖意，不同檢索者的在描述上不見得與之匹配，容易造成查無所獲的情況。
本研究旨在深入探討視覺設計者在其工作任務中所展現的圖像檢索行為，如何進行圖像檢索、資訊來源與管道的取得方式、使用的關鍵字類型，以及對圖像相關性的評估過程，以質性研究的角度，透過檢索任務和訪談法作為資料蒐集和分析的依據進行研究。
研究結果顯示：視覺設計者以「關鍵字檢索」為主，「瀏覽」為輔的檢索策略；網路資源是視覺設計者重要的圖像尋求管道，尤其是Pinterest和Google Image；多樣的標準評估圖像相關性，包含了主題性、主觀美學、啟發性、情感以及技術屬性；關鍵字呈現多樣性，主要以特定概念和一般概念的名詞為主，情感詞彙也是很重要的概念。

Traditionally, libraries, museums, galleries, and archives have been the primary institutions providing vast collections of images, including paintings, artifacts, and historical documents. With the advent of the internet, image resources can now be accessed and utilized through a variety of channels. Image search engines, social media platforms, and databases are some of the image retrieval tools that have emerged.
In current image retrieval systems, the organization of image information largely relies on either manual indexing by individuals or automated processes. However, images possess unique characteristics that distinguish them from textual information; they contain multiple layers of visual content. A single keyword can evoke numerous images, and a single image can inspire a wide range of descriptive terms. If these textual descriptions fail to accurately convey the image's meaning, there may be a mismatch between the searcher's intent and the results, often leading to unsuccessful retrievals.
This study aims to deeply explore the image retrieval behaviors exhibited by visual designers during their work tasks, focusing on how they conduct image searches, the sources and channels through which they acquire information, the types of keywords they use, and the processes they employ to evaluate image relevance. The research adopts a qualitative approach, using retrieval tasks and interviews as the basis for data collection and analysis.
This study aims to explore in-depth the image retrieval behaviors exhibited by visual designers during their work tasks, focusing on how they conduct image searches, the sources and channels through which they acquire information, the types of keywords they use, and the processes they employ to evaluate image relevance.
The research findings reveal that visual designers primarily use a "keyword search" strategy, supplemented by "browsing." Online resources, particularly Pinterest and Google Images, are vital channels for visual designers seeking images. The evaluation of image relevance is based on a variety of criteria, including thematic relevance, subjective aesthetics, inspirational value, emotional impact, and technical attributes. The keywords used by designers display diversity, with a strong emphasis on both specific and general concepts, while emotional terms also play a significant role in their search strategies.
