The PhD thesis of Hartwig Hochmair deals with wayfinding in the web. A main topic is to find out in which way this mental representation of the environment of an object changes through perception of information, which can be modelled by an agent with state. Close to this is the attempt to find out, how links in a web should be connected so that a wide group of users can find the wanted web site. The solution is a web structure that corresponds widely to the user's mental model. Further research looks at possibilities to compare the changes of mental models on navigating through real space and web space.
Laws are an important part of everyday life.
Many laws regulate the coexistence of citizens. The system formed by the laws is complex and, therefore, it is hard to understand the system or to adopt it to new situations. Even lawyers may have problems if trying to understand the meaning of specific laws. For non-professionals it is therefore impossible to consider the legal situation completely if setting actions. A model can improve the understanding of a law.
