In the article we discuss ongoing work concerning a confrontational German-Slovak collocation lexical database. The database consists of two parts, a section of German collocations with Slovak equivalents and a section of Slovak collocations. Intended size of the database is several hundred words of different parts of speech (nouns in the first phase of the project) for each of the languages, together with their collocation profiles. The database uses MediaWiki engine and a wiki-based approach to article editing and collaborative work of a team of lexicographers.
