BOND: A Deep Dive into BERT-Assisted Open-Domain Named Entity Recognition

Oct 6, 2020 | Data Science

Welcome to the world of BOND (BERT-Assisted Open-Domain Named Entity Recognition with Distant Supervision). In this article, we will explore the capabilities of BOND and guide you through the process of using its code and pre-processed distantly weakly labeled data as outlined in our research paper published at KDD 2020. Let’s unlock the potential of AI-powered entity recognition!

What is BOND?

BOND leverages BERT, a cutting-edge language model, to perform Named Entity Recognition (NER) tasks across various domains. Using distant supervision, BOND enables efficient training with weakly labeled datasets, significantly enhancing performance in recognizing named entities across different contexts.

Understanding the Results

The following table summarizes the entity-level F1 scores achieved by BOND compared to other methods:

Method           CoNLL03     Tweet      OntoNote5.0  Webpage     Wikigold
------           -------     -----      -----------  -------     --------
Full Supervision 91.21       52.19     86.20        72.39       86.43
Previous SOTA    76.00       26.10     67.69        51.39       47.54
BOND             81.48       48.01     68.35        65.74       60.07

This can be understood with an analogy: imagine a highly skilled detective (Full Supervision) who has access to all evidence and resources. In comparison, a team of detectives (Previous SOTA) working with limited resources forms a collective effort but still falls short. Now, think of BOND as a rookie detective using a smart assistant (BERT) to analyze various datasets, ultimately achieving respectable results and closing the gap with seasoned professionals.

Data Availability

BOND provides five open-domain distantly weakly labeled NER datasets for researchers and developers. You can find these datasets for your use in this repository. If you require gazetteers information or need the code for distant label generation, feel free to contact us at cliang73@gatech.edu.

Setting Up Your Environment

To get started with BOND, you’ll need the right environment. Ensure you have the following:

  • Python 3.7
  • Pytorch 1.3
  • Hugging Face Transformers v2.3.0

Training and Evaluation Scripts

BOND provides training scripts for all five open-domain datasets. Here are some example commands for training and evaluating the model:

cd BOND
# For BOND training and evaluation on CoNLL03
sh scripts/conll_self_training.sh

# For Stage I training and evaluation on CoNLL03
sh scripts/conll_baseline.sh

When you run these commands, think of it as instructing a well-trained assistant on specific tasks; once they start, they can efficiently complete the job at hand.

Troubleshooting

While using BOND, you might encounter some issues. Here are a few troubleshooting tips:

  • Environment Issues: Double-check that your Python and Pytorch versions are compatible. You can install the necessary packages using pip.
  • Data File Errors: Ensure that the datasets are correctly placed within the directory and named as expected.
  • Script Failures: If a script fails, refer to the error message carefully—it often provides valuable clues on what went wrong.
  • Performance Discrepancies: If BOND’s performance isn’t quite matching the reported F1 scores, consider tweaking the training parameters or verifying your data pre-processing steps.
