Universal Derivations (UDer) is a collection of harmonized lexical networks capturing word-formation, especially derivational relations, in a cross-linguistically consistent annotation scheme for many languages. The annotation scheme is based on a rooted tree data structure, in which nodes correspond to lexemes, while edges represent derivational relations or compounding.
The UDer collection was created on the initiative to capture word-formation in the UFAL-led lexical network DeriNet. Therefore, each individual resource in the UDer collection can be searched online using DeriSearch and the data can be processed using DeriNet 2.0 API.
The current version of the collection is UDer 0.5. It contains eleven harmonized resources covering eleven different languages: Czech, English, Estonian, Finnish, French, German, Latin, Persian, Polish, Portuguese, and Spanish. Uder 0.5 is available in the LINDAT/CLARIN digital library (item: http://hdl.handle.net/11234/1-3041). The license for every harmonized resource included in the collection is specified in the appropriate language/resource directory.
