We largely follow the general annotation principles of the Penn Parsed Corpora of Historical English, adapted to the specifics of historical German. Our word-level tags are most similar to the tagset used for the Old Saxon HeliPaD corpus. Our higher-level labels correspond most closely to those of the CHLG (although CHLG uses an entirely different tagset for parts of speech.)

• Part-of-speech tags (heads)
