Abstract

Web navigation model provides a dynamic view for web modelling. It is useful for clarifying requirements and specifying implementation behaviors of systems from design intensions. In this paper, we propose a formal model to describe web navigation of user behaviors, where link activities play an important role. Several issues have been considered in our model, such as web browser effects, adaptive navigation, frame communication etc. After the link activity model is established, we use model checker SPIN to check whether there exist problems such as such as broken links, dead ends, missed reply pages, reachability of pages etc. This method can help us to analyze user behaviors, meanwhile it provides us a way to expose design faults in web systems.
