This paper investigates the problem of automatically annotating resources with NP coreference information using a parallel corpus, English-Romanian, in order to transfer, through word alignment, coreference chains from the English part to the Romanian part of the corpus. The results show that we can detect Romanian referential expressions and coreference chains with over 80% F-measure, thus using our method as a preprocessing step followed by manual correction as part of an annotation effort for creating a large Romanian corpus with coreference information is worthwhile.

We report on our experience with manual alignment of Czech and English parallel corpus text. We applied existing guidelines for English and French and augmented them to cover systematically occurring cases in our corpus. We describe the main extensions covered in our guidelines and provide examples. We evaluated both intra- and inter-annotator agreement and obtained very good results of Kappa well above 0.9 and agreement of 95% and 93%, respectively.
