A hybrid approach to resolve nominal anaphora

Abstract

In order to resolve nominal anaphora, especially definite description anaphora, various sources of information have to be taken into account. These range from morphosyntactic information to domain knowledge encoded in ontologies. As the acquisition of ontological knowledge is a timeconsuming task, existing resources often model only a small set of information. This leads to a knowledge gap that has to be closed: We present a hybrid approach that combines several knowledge sources in order to resolve definite descriptions.1
