Umean/B2NERD

B2NER

We present B2NERD, a cohesive and efficient dataset that can improve LLMs' generalization on the challenging Open NER task, refined from 54 existing English or Chinese datasets. Our B2NER models, trained on B2NERD, outperform GPT-4 by 6.8-12.0 F1 points and surpass previous methods in 3 out-of-domain benchmarks across 15 datasets and 6 languages.

Data

One of the paper's core contribution is the construction of B2NERD dataset. It's a cohesive and efficient collection refined from 54 English and Chinese datasets and designed for Open NER model training. The preprocessed test datasets (7 for Chinese NER and 7 for English NER) used for Open NER OOD evaluation in our paper are also included in the released dataset to facilitate convenient evaluation for future research.

We provide 3 versions of our dataset.

• B2NERD (Recommended): Contain ~52k samples from 54 Chinese or English datasets. This is the final version of our dataset suitable for out-of-domain / zero-shot NER model training. It features standardized entity definitions and pruned, diverse data.
• B2NERD_all: Contain ~1.4M samples from 54 datasets. The full-data version of our dataset suitable for in-domain supervised evaluation. It has standardized entity definitions but does not undergo any data selection or pruning.
• B2NERD_raw: The raw collected datasets with raw entity labels. It goes through basic format preprocessing but without further standardization.

You can download the data from HuggingFace or Google Drive. Current data is uploaded as .zip for convenience. We are considering upload raw data files for better preview.
Please ensure that you have the proper licenses to access the raw datasets in our collection.
