The resource represents knowledge for the domain of karstology, a subfield of geography studying karst and related phenomena. It contains:

1. Definitions Plain text files contain definitions of karst concepts from relevant glossaries and encyclopaedia, but also definitions which had been extracted from domain-specific corpora.
