1. Information Scent as a Driver of Web Behavior Graphs: Results of a Protocol Analysis Method for Web Usability

2. Information Foraging Theory Information foraging theory is an approach to understanding how user strategies and technologies for information seeking, gathering, and consumption are adapted to the flux of information in the environment.

3. Approach Problem about: Cognitive representations and processes in WWW interaction. Solution: Based on the information foraging theory, introduced a replicable WWW protocol analysis methodology illustrated by application to data collected in the laboratory.

4. Protocol Transcription A protocol transcription contains: the URL of the currently displayed Web page, an image of the Web page on the screen, the times for selected events, derived from the WebLogger file, a transcript of the user’s verbal utterances, appropriately segmented, and interpretive encoding of the events.

5. Patches of the information Space Web. Web site. Page: A page can be thought of as a patch containing link descriptors, content- elements, link descriptors, URL, and keyword.

6. Problem Spaces for Web Search

7. Phenomena the methodology rises: The propensity of users to make their link choices based on the information scent of links (scent-following). The propensity of users to switch to another information patch when the information scent of the current site becomes low ( patch scent policy).

9. Conclusion A user is assessing the potential rewards of foraging at a site based on information scent. As the potential rewards are above some threshold, then the user continues foraging at the site. When the potential rewards pass below that threshold, then the user moves on to another site.
