Resolving Coreferent and Associative Noun Phrases in Scientific Text
Ina Roesiger, Simone Teufel · 2014
We present a study of information status in scientific text as well as ongoing work on the resolution of coreferent and associative anaphora in two different scientific disciplines, namely computational linguistics and genetics. We present an annotated corpus of over 8000 definite descriptions in scientific articles. To adapt a state-of-the-art coreference resolver to the new domain, we develop features aimed at modelling technical terminology and integrate these into the coreference resolver. Our results indicate that this integration, combined with domain-dependent training data, can outperform the performance of an out-of-the-box coreference resolver. For the (much harder) task of resolving associative anaphora, our preliminary results show the need for and the effect of semantic features.
