We present an ongoing project of enriching an annotation of a parallel dependency treebank, namely the Prague Czech-English Dependency Treebank, with verb-centered semantic annotation using a bilingual synonym verb class lexicon, CzEngClass. This lexicon, in turn, links the predicate occurrences in the corpus to various external lexicons.
This paper describes a first milestone of a long-term project; so far, approx. 100 CzEngClass classes, containing about 1800 different verbs each for both Czech and English, are available for such annotation.
