Changes compared to previous journalistic corpora

The lemmatization and morphological tagging of SYN2013PUB were improved in comparison with the previous corpora. Apart from that, the tagset itself was further simplified in a few cases when the information provided in the tags would be superfluous, hardly recognizable in the context, and thus unreliable. The changes concerned the following:

  • removing number for reflexive pronouns
  • removing possessor's gender for pronouns jeho, jejich
  • removing person and number for the word form by

Works on supplementing the synchronic written corpora with newer data are underway.
