中文摘要

上網重複查詢先前瀏覽資源之資訊再尋獲行為十分常見,但由於網路環境之變動性及資訊尋獲情境之多元性,資訊再尋獲與一般尋獲或查詢行為可能存在差異。本研究以實驗、觀察、訪談、問卷等方法,嘗試瞭解網路使用者之資訊再尋獲檢索行為特性;同時,也分析比較尋獲與再尋獲兩階段之檢索歷程特性。研究結果顯示,相較資訊尋獲行為,使用者於資訊再尋獲過程中所使用之檢索工具更為多元、也會交互使用多種檢索策略尋得先前情境線索、其所採用之檢索技巧較為複雜、與系統的互動也較為頻繁。根據實驗結果,資訊再尋獲雖較尋獲階段所花費時間較短,但其所需認知心力及檢索困難度也增加不少。一般而言,受試者對再尋獲的結果多感滿意,但也表示若系統能提供更多回想支援功能,再尋獲的檢索成效其實應該更高。此外,本研究也提供不同檢索任務類型對資訊再尋獲影響之初步分析結果。最後,本研究針對網路資訊檢索系統及個人資訊管理層面提出一些改善建議。

英文摘要

It is common for users to relocate information previously found on the web. However, their search behaviors in initial fnding and the subsequent re-fnding may differ due to the dynamic na-
ture and contextual diversity of the web. This study used experiment, observation, interview, and questionnaires to investigate the characteristics of re-fnding behavior and compare users’ performance
in fnding and re-fnding. Though not signifcantly different, the study participants used more search tools, combined various strategies to obtain contextual clues of fnding process, utilized more complex search tactics, and had more interactions with search engines used. Findings also show that partici-pants spent less time in re-fnding than in fnding, yet the cognitive loading and diffculties increased
in re-fnding. Participants were satisfed with the results obtained in re-fnding, but they also claimed that the search performance would be better if the system offered more functions to support recall of previous search results. Participants’ satisfaction with search performance also varied by task type.
Based on the fndings, this study recommends that re-fnding effciency may be improved by enhanc-ing recall functionalities in browsers and by using personal information management tools.
