# CoReNer

## Model description

A multi-task model for named-entity recognition, relation extraction, entity mention detection and coreference resolution.

We model NER as a span classification task, and relation extraction as a multi-label classification of (NER) span tuples.
Similarly, model EMD as a span classification task and CR as a binary classification of (EMD) span tuples.
To construct the CR clusters, we keep the top antecedent of each mention, then compute the connected components of the mentions' undirected graph.
