Abstract

In this paper, we discuss the application of UBIU to the CoNLL-2011 shared task on "Modeling Unrestricted Coreference" in OntoNotes. The shared task concentrates on the detection of coreference not only in noun phrases but also involving verbs. The information provided for the closed track included WordNet as well as corpus generated number and gender information. Our system shows no improvement when using WordNet information, and the number information proved less reliable than the information in the part of speech tags.
