"這類模型很少能發展到與特定理論命題建立關聯：只能說是處在一個前

理論的階段，而所描繪的關係或者能有助於往後的探索或檢驗”"rarely do such models advance to the stage of specifying relationships among theoretical propositions: rather

they are at a pre-theoretical stage, but may suggest relationships that might be fruitful to explore or test.

模型 MODELS

3 Criterions3 Criterions

1. 該模型能就相關變數描繪並闡明行為序列，而非僅僅指出事件的順序而非僅僅指出事件的順序The model attempts to depict and explain a sequence of behavior by referring to relevant variables, rather than merely indicates a sequence of events.

2. 該模型需涵蓋資訊需求與來源The model indicates something about information needs and sources. (Ellis & Kuhlthau)

3. 為通用的行為模型，而非特定職業或身份General models

reflect)、或評估(evaluate)週遭的變化。資訊行為是在反映與評估間建構而起的；特別是關於反映或評估知識的缺乏。並由對知識缺乏的感；知作為起點，開始一資訊(搜尋)行為的序列。

• 資訊視域：當個人決定要進行搜尋行為時，他會在他的資訊視域(information horizon)中尋找資訊。horizon)中尋找資訊。

• 協同合作：人類資訊搜尋行為，理論上，可以視為一種個體與其資訊資源間的協同合作。

• 解決方案效益：因為資訊視域是由各種資訊資源所組成，各自擁有部分的知識，因此可以將資訊視域概念化為密集空間(densely populated spaces)。在密集解決方案空間中，假定有許多解決方案，而資訊搜尋spaces) 在密集解決方案空間中 假定有許多解決方案 而資訊搜尋問題由決定其中最有效率的路徑展開。
