When we examine the thesauri prepared in the framework of college or university dissertations, we can draw important lessons. The outcomes reveal not only all the common mistakes that are characteristic of LIS students' dissertation works, but also the shortcomings of the teaching of the subject at LIS schools. In these dissertations, Hungarian library standards are sometimes ignored, while problems can be observed in the distinction of conceptual and linguistic levels as well as in interpreting generic relations. The teaching of thesauri cannot be separated from the teaching of the MARC21 and HUNMARC data exchange formats for authority data. LIS students should get thorough and exhaustive training in this field, especially because they will work with these formats on.

The hierarchy of ontologies based on generic relation is described by exact logical declarations. However, generic hierarchy itself depends on philosophical views and intuition. In other words, depending on aspect and intuition it can be chosen different conceptual hierarchy. The author shows that in generic hierarchy of top-level concepts there are not really unsolvable differences. Which means that the second expected consequence will not be realized. Consequently: however big are the differences between the special hierarchies of the ontologies, by necessity the basis of the apparently different hierarchies is the same concept system. For comparison he used top-level concepts of universal Hungarian Thesaurus (Koztaurus) as a basis. From the results of the comparison it can be concluded that the Hungarian adaptation of the internationally developed ontologies has no significant difficulties.
