AllenNLP is an open-source NLP research library built on PyTorch for developing state-of-the-art deep learning models on linguistic tasks. It is now in maintenance mode with no new features or dependency upgrades, and support ended in December 2022.

Use cases

• train text classification models in pytorch
• build named entity recognition models
• run semantic role labeling experiments
• prototype NLP research models with a config-driven trainer
• compute NLP evaluation metrics
• vectorize text with pretrained embeddings

When to choose

• you are maintaining or reproducing an existing AllenNLP-based project
• you need its Fairness or Interpret components with no replacement
• you want a stable pinned environment for legacy NLP research code

When to avoid

• you are starting a new NLP project - use Hugging Face transformers or flair instead
• you need actively maintained dependencies or new model architectures
• you want experiment management - use AI2 Tango or torchmetrics for its trainer/metrics roles
