This repository contains datasets from several domains annotated with a variety of entity types, useful for entity recognition and named entity recognition (NER) tasks.
NOTE: I am no longer actively adding datasets to this list -- there are likely more NER datasets that have appeared since 2020. However, I am happy to add more datasets via issues or pull requests.
The following table shows the list of datasets for English-language entity recognition (for a list of NER datasets in other languages, see below). The data directory contains information on where to obtain those datasets which could not be shared due to licensing restrictions, as well as code to convert them (if necessary) to the CoNLL 2003 format. Links to NER corpora in other languages are also listed below.
