Titel: Modeling Navigation in Information Networks


While a plethora of hypertext links exist on the Web, only a small amount of them are regularly clicked. Starting from this observation, we set out to study large-scale click data from Wikipedia in order to understand how people navigate in information networks. We systematically analyze effects of link properties on the popularity of links. By utilizing mixed-effects hurdle models supplemented with descriptive insights, we find evidence of user preference towards links leading to the periphery of the network, towards links leading to semantically similar articles, and towards links in the top and left-side of the screen. This work facilitates understanding navigational click behavior and thus can contribute to improving link structures and algorithms utilizing these structures.
