Both the XML example given earlier which modelled vehicle classification as a hierarchy and Formal Concept Analysis which also employs a classification hierarchy (see example in Fig 2) are flawed in that it can lead to situations where a thing classified by it immediate parent, isn't classified by the parent of the parent.
Take a look at all the links between various nodes in Fig 2 and determine if there is a consistent relationship between nodes taking into account direction of the link. Basically the most consistent relationship seems to be that a lower node is an instance/example of the upper node. You can ignore top and bottom nodes which represent Universal Concept and NULL respectively. So what is the relationship between mammal and cartoon? Is cartoon a mammal?
