Therefore I decided to lemmatize, using the morphological analyser Estmorf, which automatically lemmatized and disambiguated the whole corpus. |
If we lemmatize the collocates and also look at lexical sets, then the power of attraction of the head-words is seen to be much stronger again. |
Unfortunately, lemmatization requires a lot more work up-front as it needs a complete vocabulary and morphological analysis to correctly lemmatize words. |
