Erdelez 第一步(1997)說明並描繪資訊偶遇概念的存在。 Erdelez 第二步(2000)以網路資訊環境的特徵作為資訊偶遇的環境。
Erdelez(1997)認為資訊偶遇(IE)包含三元素:
- characteristics of information user 資訊使用者的人格特性
- characteristics of the information environment 資訊環境的特徵
- characteristics of encountered information 偶遇資訊的特徵
Erdelez(1997)根據使用者的經驗，區分四種資訊偶遇族群：
- super-encounterers
- encounterers
- occasional encounterers
- non-encounterer
資訊偶遇與資訊行為
資訊偶遇在資訊行為中的定位：
- 資訊行為
- 資訊獲取
- 有意圖的獲取資訊: 資訊尋求
- 機會式的獲取資訊(OAI)
- 資訊偶遇(IE)
- 其他 OAI 形式
- 其他資訊行為
資訊偶遇的功能模式
IE 的功能模式 (2004)
- steps:
- noticing
- stopping
- examining
- capturing
- returning
- 此模式假定以下存在:
- initial information-seeking task –> as user's foreground problem
- this foreground problem is inactive in the background
Note
- 雖然 Erdelez 提出不屬於傳統資訊尋求行為的概念，但仍然是以資訊需求為行動的動機。只是此動機隱含在直接提出問題的背後。
