😎: This is the official implementation of 🪞Mirror which supports almost all the Information Extraction tasks.

The name, Mirror, comes from the classical story Snow White and the Seven Dwarfs, where a magic mirror knows everything in the world. We aim to build such a powerful tool for the IE community.

🔥 Supported Tasks

1. Named Entity Recognition
2. Entity Relationship Extraction (Triplet Extraction)
3. Event Extraction
4. Aspect-based Sentiment Analysis
5. Multi-span Extraction (e.g. Discontinuous NER)
6. N-ary Extraction (e.g. Hyper Relation Extraction)
7. Extractive Machine Reading Comprehension (MRC) and Question Answering
8. Classification & Multi-choice MRC

The pre-trained Mirror model currently supports English IE tasks. If you are looking for a model supporting Chinese IE tasks, please refer to Spico/mirror-chinese-mrcqa-alpha, which is a very early attempt before Mirror comes out.

🌴 Dependencies

Python>=3.10

pip install -r requirements.txt

🚀 QuickStart

Pretrained Model Weights & Datasets

Download the pretrained model weights & datasets from [OSF] .

No worries, it's an anonymous link just for double blind peer reviewing.

Pretraining

1. Download and unzip the pretraining corpus into resources/Mirror/v1.4_sampled_v3/merged/all_excluded
2. Start to run

CUDA_VISIBLE_DEVICES=0 rex train -m src.task -dc conf/Pretrain_excluded.yaml

Fine-tuning

⚠️ Due to data license constraints, some datasets are unavailable to provide directly (e.g. ACE04, ACE05).

1. Download and unzip the pretraining corpus into resources/Mirror/v1.4_sampled_v3/merged/all_excluded
2. Download and unzip the fine-tuning datasets into resources/Mirror/uie/
3. Start to fine-tuning

# UIE tasks
CUDA_VISIBLE_DEVICES=0 bash scripts/single_task_wPTAllExcluded_wInstruction/run1.sh
CUDA_VISIBLE_DEVICES=1 bash scripts/single_task_wPTAllExcluded_wInstruction/run2.sh
CUDA_VISIBLE_DEVICES=2 bash scripts/single_task_wPTAllExcluded_wInstruction/run3.sh
CUDA_VISIBLE_DEVICES=3 bash scripts/single_task_wPTAllExcluded_wInstruction/run4.sh
# Multi-span and N-ary extraction
CUDA_VISIBLE_DEVICES=4 bash scripts/single_task_wPTAllExcluded_wInstruction/run_new_tasks.sh
# GLUE datasets
CUDA_VISIBLE_DEVICES=5 bash scripts/single_task_wPTAllExcluded_wInstruction/glue.sh

Analysis Experiments

• Few-shot experiments : scripts/run_fewshot.sh. Collecting results: python mirror_fewshot_outputs/get_avg_results.py
• Mirror w/ PT w/o Inst. : scripts/single_task_wPTAllExcluded_woInstruction
• Mirror w/o PT w/ Inst. : scripts/single_task_wo_pretrain
• Mirror w/o PT w/o Inst. : scripts/single_task_wo_pretrain_wo_instruction

Evaluation

1. Change task_dir and data_pairs you want to evaluate. The default setting is to get results of Mirror_direct on all downstream tasks.
2. CUDA_VISIBLE_DEVICES=0 python -m src.eval

Demo

1. Download and unzip the pretrained task dump into mirror_outputs/Mirror_Pretrain_AllExcluded_2
2. Try our demo:

CUDA_VISIBLE_DEVICES=0 python -m src.app.api_backend

🛣️ Roadmap

• Convert current model into Huggingface version, supporting loading from transformers like other newly released LLMs.
• Remove Background area, merge TL, TP into a single T token
• Add more task data: keyword extraction, coreference resolution, FrameNet, WikiNER, T-Rex relation extraction dataset, etc.
• Pre-train on all the data (including benchmarks) to build a nice out-of-the-box toolkit for universal IE.
