Abstract
In WordNet, the lexicalized noun/ verb concepts are organized hierarchically by means of hypernymy. As the most basic semantic relation, hypernymy not only serves to construct the specific hierarchy of the concepts in the domain, but also provides a common way of reasoning along the hierarchy for NLP researchers. However, we’ve found two kinds of inappropriate hierarchy in WordNet, the cases of ring and isolator for short. This paper offers a comprehensive study of these cases and make clear that they can cause a degenerate structure, hence harass the reasoning and eventually lead to errors.
