Some structural tests for WordNet with results
Ahti Lohk, Heili Orav, Leo Võhandu · 2014
This paper proposes some test-patterns (viewed as sub-structures) to evaluate the hierarchical structure of wordnets.By observing hierarchical structure, both top-down and bottom-up experiments are carried out on four wordnets: Princeton WordNet (version 3.1), Cornetto (version 2.0), the Polish Wordnet (version 2.0) and the Estonian Wordnet (version 67).The top-down approach is used to find small hierarchies, which are defined as having up to three levels of subordinates starting from unique beginners (rootsynsets).The bottom-up perspective is looking at the links that appear due to polysemy, and yet these are not.These redundant links form "asymmetric ring topology", and should be eliminated.Finally, an additional particular feature of large closed subsets will be introduced.Addressed views provide an opportunity to evaluate and/or improve the structure of wordnet hierarchies.This paper also provides an overview of the current status of these four wordnets from the according to our proposed test patterns.
