## Dataset Description
- **Repository:** [CrossNER](https://github.com/zliucr/CrossNER)
- **Paper:** [CrossNER: Evaluating Cross-Domain Named Entity Recognition](https://arxiv.org/abs/2012.04373)

### Dataset Summary
CrossNER is a fully-labeled collected of named entity recognition (NER) data spanning over five diverse domains 
(Politics, Natural Science, Music, Literature, and Artificial Intelligence) with specialized entity categories for 
different domains. Additionally, CrossNER also includes unlabeled domain-related corpora for the corresponding five 
domains.

For details, see the paper: 
[CrossNER: Evaluating Cross-Domain Named Entity Recognition](https://arxiv.org/abs/2012.04373)

Dataset Description
-------------------


* Repository: CrossNER
* Paper: CrossNER: Evaluating Cross-Domain Named Entity Recognition


### Dataset Summary


CrossNER is a fully-labeled collected of named entity recognition (NER) data spanning over five diverse domains
(Politics, Natural Science, Music, Literature, and Artificial Intelligence) with specialized entity categories for
different domains. Additionally, CrossNER also includes unlabeled domain-related corpora for the corresponding five
domains.


For details, see the paper:
CrossNER: Evaluating Cross-Domain Named Entity Recognition


### Supported Tasks and Leaderboards


### Languages


The language data in CrossNER is in English (BCP-47 en)
