# Corpus SYN2006PUB

All three corpora are disjunctive as to the texts used, that is no text, which is part of one corpus, is included in the other two. Corpora SYN2000, SYN2005 and SYN2006PUB thus contain a total of 500 million text words (tokens).

## Changes compared to the SYN2005 corpus

The lemmatization and morphological tagging of the SYN2006PUB corpus have been improved in comparison with the SYN2005 corpus, although the difference is not as striking as in the case of SYN2000 and SYN2005 corpora. The system of morphological tags, the tokenization (division of the corpus into words) and segmentation (division into sentences) remains the same as in the SYN2005 corpus.
