本論文研究利用觀察歸納和質性方法探討非英語母語網路使用者利用英文進行資訊
蒐集之行為模式，研究在資訊蒐集的過程中使用者遭遇何種困難，及語言障礙是否影
響使用者的資訊蒐集行為，又擁有不同母語的兩個族群是否資訊蒐集行為會有所不同。各五名受試者分別來自台灣及印尼進行兩個不同面向的資訊蒐集實驗，分別為特定資訊(fact-finding)蒐集和開放式資訊(exploratory)蒐集。實驗過程中受試者被要求使用think-after 方法，螢幕的操作過程及對話和實驗後的訪談及皆被記錄以進行質性及觀察歸納分析。實驗觀察結果利用Holscher and Strube 的資訊蒐集模進行分析和比對，而質性資料進行Grounded Theory 分析。質性及觀察歸納結果顯示語言對資訊蒐集行為的影響，在觀察歸納中發現，非英語母語使用者傾向以orienteering 的方式連結到已知網站，而非直接輸入網域網址。另一方面，質性研究結果顯示語言對於非英文母語者進行資訊搜尋的顯著地位，在分析結果中的七個主要類別中，與語言相關類別分別占了三項，分別是語言因素、使用者偏好以及關鍵字構想。

This study applied a mixed approach to investigate English-as-second-language (ESL)users’ information search behavior when they search for information online in English.Five Taiwanese and five Indonesian students were recruited to perform two types of life-like information search tasks, fact-finding and exploratory. Actions on screen and utterance from retrospective think-aloud protocols were recorded. None of the participants are English native speakers but have demonstrated adequate language proficiency to perform searches in English by providing official test scores. For observational data,experiment processes were screen recorded and divided into separate action units in order to map Holscher and Strube’s information search model and compare to their original results. Qualitative data were collocated and transcribed from retrospective think-aloud
protocols and post-interviews with open-ended questions. Transcripts were coded and analyzed based on grounded theory. From both observational and qualitative results, language effects on ESL users’ information search behavior were identified. In observational result, participants access to known websites by orienteering instead of teleporting due to the need of lessening cognitive effort. Additionally, the results yielded from qualitative approach further confirmed that language dose play an important role in ESL Web users’ information search process.
