In this paper, we examine the possibility of using annotation projection from multiple sources for automatically obtaining coreference annotations in the target language. We implement a multi-source annotation projection algorithm and apply it on an English-German-Russian parallel corpus in order to transfer coreference chains from two sources to the target side. Operating in two settings -a low-resource and a more linguistically-informed onewe show that automatic coreference transfer could benefit from combining information from multiple languages, and assess the quality of both the extraction and the linking of target coreference mentions.
Thereafter, REF proposed a multi-source method for annotation projection: They used a manually annotated trilingual coreference corpus and two source languages (English-German, English-Russian) to transfer annotations to the target language (Russian and German, respectively).
