DErivBase and DErivCELEX

DErivBase is a large-coverage derivational lexicon for German (Zeller et al., 2013). It consists of derivational families, groups of lemmas which are derivationally related among each other. Since v2.0, such derivational families are automatically split into semantically consistent clusters (Zeller et al., 2014). Version 2.0 covers 280,336 lemmas; 65,420 of them are grouped into 20,371 non-singleton families (i.e., 214,916 are singleton families). The lexicon was extracted from SDeWAC, a large German web corpus, with HOFM, a rule-based framework written in Haskell

DErivCELEX is a derivational lexicon for German (Shafaei et al., 2017) with a structure similar to DErivBase. It was constructed on the basis of German CELEX, a large, manually constructed lexicon resource. DErivCELEX covers roughly 47.000 lemmas grouped into 28.000 families. Its lexical coverage is lower than that of DErivBase (in particular with regard to the long tail of infrequent words), but it is built on the basis of a cleaner resource and thus contains fewer false positives.
