The aim of the thesis is to compare advantages and disadvantages of glossary-making procedure that is based on three comparable corpora. The corpora differ not only in compilation method, but mainly in their purpose of the content. The most controversial issue is the use of translations as a source for corpus compilation, but its use has its particular purpose in this case. Such corpus-based glossaries will be further used for translation of a specific language – language of climbing and mountaineering. The hypothesis that an efficient glossary can be created if extracted terms and keywords are compared has not been entirely validated, because some glossary entries needed to be sought via concordancer or within other glossaries.
