Download Solution PDF

The Correct answer is C, D, and E only.

Key Points

  • The stratified model begins with two fundamental assumptions:
    • first, that users engage with information retrieval (IR) systems to access information, and
    • second, that the use of this information is linked to cognitive processes and practical application in specific situations.
  • These assumptions, while seemingly obvious, provide a foundation for the model's focus.
  •  In the stratified model, the primary components are users and computers, each with their own variables, engaged in interactions through an interface. While the interface facilitates these interactions, it is not the central focus.
  • The interface operates at the surface level, where observations can be made regarding user actions, computer responses, collaboration, and patterns in different situations. 
  • On the user side, we can identify three initial levels: Cognitive, Affective, and Situational.
  • Each level represents different aspects of the user's experience and engagement with information.
