There are two coreference annotators to choose from within cTAKES.

If you aren't sure which one to choose, use

CoreferenceAnnotatorFactory.getDefaultCoreferencePipeline()

Legacy Coreference Resolution

There are four annotators that together create coreference annotations.

• MipacqMarkableCreator
• MipacqMarkableExpander

MentionClusterCoreferenceAnnotator aka Coreference using Clusters

MentionClusterCoreferenceAnnotator is new for 4.0. It uses the org/apache/ctakes/coreference/models/mention-cluster/model.jar model in the coreference-res project.

See CoreferenceAnnotatorFactory.getMentionClusterResolverDescription()

MentionClusterCoreferenceAnnotator has a convenience method for adding it to UimaFit pipelines. The method takes a model path argument.
