使用者先前知識, 導航輔助及超文本檢索表現之關係

Abstract

目前已進入網路盛行的時期，網頁內容製作者將大量資訊傳遞給使用者，但使用者背景知識不是製作者所能預期的。當使用者先前知識程度不同時，對於超文本的運用程度自然不同。本研究的目的在尋找可以讓不同知識程度的使用者皆可運用超文本內容的方法，假設專家與生手的瀏覽路徑不同，並將專家的路徑製作成導航輔助圖，輔助生手檢索，假設運用輔助圖的生手的檢索表現會優於未使用輔助圖的生手。 研究者將圖書館學建成網頁，分別記錄圖書館員（專家組）及大學部學生（分為兩組代表生手）的檢索表現。結果顯示，專家在檢索效率上優於生手，但檢索時間卻沒有顯著差異；運用導航輔助圖的生手，確實在檢索時間及表現上優於未運用輔助圖的生手。未來研究者可以再加以評估記憶以及興趣等方面。

Now is the time when the internet prevails. The page content author delivers lots of information to the user. However, the author can't expect that every user's prior knowledge level is equal. User's prior knowledge really affect the amount he accepts. In this research, we try to find a way which let different users all can optimize the hypertext content. According the reference, we suppose experts' path and novices' path are different. In this research, we invite librarians as the expert group and the university students as novice group. By log files, we record the experts' and novices' path to compare the difference. Then we afford the novices a map, which is constructed with experts' path. After the experiment, we get some conclusion. First the experts' search performance is really better than the novices'. Second the novices who use the map really perform better than those without map. In future, researchers can evaluate the interest and memory dimensions continually.
