Additionally, we want to validate our assumption, that by first looking up word forms and their lemmas in Wiktionary, we should be able to improve the performance of existing software for lemmatization.
we evaluate IWNLP and existing software on three German corpora, which list words and their lemmas: TIGER Corpus (Brants et al., 2004), Hamburg Dependency Treebank (HDT) (Foth et al., 2014) and TüBa-D/Z (Telljohann et al., 2012) release 9.1.
