思考風格對圖片搜尋行為與搜尋策略之影響

Abstract

網路世代的來臨，改變了人們的生活習慣，上網搜尋資訊成為時常性的行為模式，尤其是「圖片搜尋」。在工作、學習、生活、休閒、教育等各方面，上網搜尋圖片都與之息息相關。圖片具有整合性，任何概念皆可用一張圖表示，且圖片資料可跨越語言的隔閡，即使是不識字的人在觀看一張圖片，也能產生個人的感覺和認知。然而，隨著多樣的搜尋內容與搜尋引擎的多方面應用，人類資訊搜尋的歷程也有了大幅度的改變。本論文將探討思考風格對圖片搜尋策略、搜尋行為的影響，並瞭解背景知識是否與搜尋策略、搜尋行為具有相關性。

本研究以國小高年級八個班級的學生進行思考風格問卷施測，挑選出四種單高思考風格學生，共68位，來進行實驗分析。透過研究者設計的圖片搜尋任務學習單暸解施測者的搜尋策略，並以搜尋時錄製的影像檔紀錄施測者的搜尋行為，後將之繪製成網路搜尋行為的導覽流程圖。

研究結果發現：不同思考風格學生之搜尋策略的「搜尋目標個數」有顯著差異性。搜尋策略的「搜尋目標個數」「關鍵字組數」「關鍵字最多組數」和搜尋行為的「探索的最大延伸度」「關鍵字的數目」「拜訪的網頁數」「搜尋的網頁數」之間也有相關性。至於背景知識對於搜尋策略的「搜尋目標個數」「選用關鍵字組數」「關鍵字最多組數」和搜尋行為的「關鍵字的數目」「拜訪的網頁數」「關鍵字的平均字數」「搜尋的網頁數」也有相關。

The coming age of the Internet has changed people’s habits and surfing the Internet has often become a behavior pattern, especially the” image search.” Searching images on the internet is close related with every aspect of working, learning, living, leisure time and education. Picture is an integrated property which any idea can be expressed in just a piece of image. The information of image can easily cross the barriers of languages and even an illiterate person would bring about feeling and knowing while watching an image. However, as the varieties of searching result and multiple applications in search engine, human in search process of information has also been a significant change. This study will get in touch with the thinking style to the effect of the image searching strategy and searching behavior; then, to understand that whether the knowledge background has related to searching strategy and searching behavior.

In this study, we use examination of questionnaire about thinking styles to pick up four kinds of students in single, high thinking styles among eight classes of high grade in elementary school, a total of 68, to carry out experimental analysis. By using the learning list of picture-searching mission, we could understand examinees’ searching strategy; meanwhile, filming them when they surf the Internet in order to record their behavior. As a result, it is possible that their behavior will be drawn as an navigation flow map.

Finally, the results showed that students with different style in “Searched number of objects” have tremendous difference between them. The searching strategy in “Searched number of objects” , “keywords number” and “the Keywords’ greatest extended matter” is also associated with “Maximum depth of exploration” , “Number ofkeywords” , “the number of webpage visited”, and “the number of webpage searched” in searching behaviors. The study also found that the knowledge background is closely connected with searching methods’ “numbers of searched targets” ,“the number of keywords selected” and “keywords number” “the number of webpage visited” ,“average word of keywords” and “the number of webpage searched” in searching behaviors.
