EELex is a web-based dictionary writing system with Estonian language support including various linguistic resources necessary for dictionary making [1, 2]. Nearly 40 dictionaries of different types (monolingual and bilingual, general and learners' dictionaries, etc.) with standard XML markup make EELex a multipurpose lexicographic database. Using the example of the active Basic Estonian Dictionary [3], this paper describes from the point of a lexicographer the functions of EELex that allow various specialized dictionaries to be generated. We focus on the generation of syntagmatic dictionaries, mainly the valency and collocation dictionaries.
