Many ontologies and wordnet type dictionaries have been created with different interactive tools using specalists semantic knowledge to model complicated relational structures. All that type man-machine systems have usually many inconsistencies which are not easy to find. In our article we present a formal methodology which analyzes and tests any given relational table and hands out with a high probability erroneus subpatterns. The final testing and estimating will again be made by a specialist. While looking for structural and lexicographic errors we present the three most known substructures that point to possible errors in wordnet hierarchical structure. An additional substructure to the group of three is a new relative structure called heart-shaped substructure. The nature of the errors for those four substructures has been described. A program written by authors is finding all such substructures in Princeton wordnet (PrWN, version 3.1) and Estonian wordnet (EstWN, version 65). The central type of error in the new substructure have been described only for Princetonwordnet.
