4.4. Authors' signatures

The authors' name abbreviations used in newspapers (e.g. ber, mas, jst... in "sentences" like PRAHA (ČTK, ber) -) have the base form in the lemma equal to the word form, they are numbered -99 and AddInfo-ed _:B_;S. Their tag has a special SUBPOS character, %. For instance, ber is annotated as ber-99_:B_;S / N%XXX-----A---8. Again, no program should rely on the number being always 99.
