A Comprehension-based Model of Web Navigation and Its Application to Web Usability Analysis

CoLiDeS, a comprehension-based cognitive model of Web navigation, offers a theoretical explanation of the impasses users often encounter during information search and retrieval from the WWW, and also identifies the determinants of success cases. In this model, acting on a single Web page screen object is regarded as the outcome of a multi-step process:

  • parsing the current display containing up to about 200 screen objects into five to ten top-level schematic objects;
  • focusing on one of these top-level schematic objects;
  • comprehending and elaborating the screen objects within the focused-on area; and then
  • selecting one of the actual screen objects as the target for the next action, the object whose representation bears the highest degree of semantic similarity to the user's goal.
