 Heat Map generated with a Semantic Fields Model using LSA. |
Thesis title: Decision Making in Webpage Environments
My supervisors (Dr Simon Dennis [1], Dr Dan Navarro [2] & Assoc. Prof. John Dunn [3]) and I are investigating people's eye movement during goal-oriented web page searches. Current we are assessing a model called Semantic Fields' (SF) ability to predict user's eye-movements.
Semantic Fields is a method we have developed to calculate the information density of a webpage based on the utility of each textual element contained on a webpage in comparison to a user's goal, with estimates of similarity calculated using several different semantic models. So far, the semantic models used in this process have been LSA, Vectorspace, and SpNMF. All of these models are accessed by the Sematic Fields method using the SEMMOD Package Semantic_Models_Package_(SEMMOD).
