Multi-source annotation projection of coreference chains: assessing strategies and testing opportunities
Yulia Grishina, Manfred Stede · 2017
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.
