## Introduction
This is the official implement for paper [BioMiner: A Multi-modal System for Automated Mining of Protein-Ligand Bioactivity Data from Literature](https://arxiv.org/abs/2604.21508).
If you encounter any issues, please reach out to jiaxianyan@mail.ustc.edu.cn.

- We introduce **BioMiner**, a multi-modal system integrating multi-modal large language models (MLLMs), domain-specific models (DSMs), and domain tools (DTs) to automatically extract protein-ligand-bioactivity triplets from thousands to potentially millions of publications at high throughput (about 20 seconds/paper on 4 A800 80G GPUs).

- To evaluate extraction capabilities and support method development, we establish a new benchmark **BioVista**, containing 16,457 bioactivity and 8,735 structures manually collected from 500 publications. To our knowledge, **BioVista** is the largest benchmark dedicated to protein-ligand bioactivity extraction.

### Overview of BioMiner and BioVista
- BioMiner integrates four specialized agents-data preprocessing, chemical structure extraction, bioactivity measurement extraction, and data postprocessing—working collaboratively to address the complicated bioactivity extraction task.

- BioVista is derived from 500 recent publications referenced in PDBbind v2020, defining two end-to-end tasks and four component-level tasks to thoroughly assess the extraction performance of BioMiner

![BioMiner_and_BioVista](https://raw.githubusercontent.com/jiaxianyan/BioMiner/main/visualization/framework_new.png)

### BioMiner's Performance on BioVista
BioMiner achieves recall rates of 0.32 for bioactivity triplet (protein-SMILES-bioactivity value). **Notably, its Markush enumeration capability achieves an F1 score of 0.70.**
More detailed analysis result are shown in the figure.

![BioVista_Performance](https://raw.githubusercontent.com/jiaxianyan/BioMiner/main/visualization/benchmark_new.png)

## Statistics and Access of BioVista
BioVista defines two end-to-end tasks and four component-level tasks to thoroughly assess the extraction performance of BioMiner.

The two end-to-end tasks evaluate overall extraction capability, specifically: 
- (1) extracting all bioactivity data reported in a publication;
- (2) annotating PDB structures with bioactivity information presented in associated papers.

Additionally, four specialized component-level tasks provide deeper insights into the performance of critical **chemical structure extraction**, facilitating method development and optimization: 
- (3) molecule detection;
- (4) optical chemical structure recognition (OCSR);
- (5) full-structure coreference recognition;
- (6) Markush structure enumeration.

Downloading BioVista according to the following links, and unzip them in the `./BioVista` directory.

**Note 1**: Due to the copyright, for paper pdfs, we only give the pdb name of these 500 papers. You can download corresponding papers based on PDB's paper title.

**Note 2**: Due to the copyright, for augmented images used for full structure corefernece recognition and Markush enumeration, we only provide the codes to generate augmented images based on pdfs. After downloading all pdfs, you can generate the augmented images based on our codes.

**Note 3**: More details can be found in [here](./BioVista/)

## Installation of BioMiner

BioMiner coordinates MLLMs (BioMiner-Instruct), DSMs (MolDetv2, MolGlyph), and DTs (RDKit, OPSIN) together. All of them are open-weight models.

- **MolDetV2**: Download the model weight from DP Tech Team's [HuggingFace Repo](https://huggingface.co/UniParser/MolDetv2). Saving the model weight as `scripts/moldet_v2_yolo11n_960_doc.pt`
- **MolGlyph**: Download the model weight from our [HuggingFace Repo](https://huggingface.co/jiaxianustc/MolGlyph). Saving the model weight as `scripts/molglyph_large.pt`
- **BioMiner-Instruct**: Download the model weight from our [HuggingFace Repo](https://huggingface.co/jiaxianustc/BioMiner-Instruct). Saving the model weight to the directory `scripts/local-biominer-instruct`

Performance of these models on BioVista:

### Running Installation

We recommend to install two conda environments, one main env for running the main code, one vllm env for delopying MLLM BioMiner-Instruct using vllm.

We provide the yaml files to help install environment.

#### 1. Install main env
```
conda env create -f main_environment.yml
conda activate BioMiner

# Prepare MinerU config json
mv magic-pdf.json ~
# Check if install MinerU v1.3.1 gpu version successfully
magic-pdf --version
# Download MinerU model checkpoints
python download_models.py
# it only takes several seconds to process a pdf for gpu version
magic-pdf -p example/pdfs/40_6s8a.pdf -o ./output
```

**Particularly,** in BioMiner, we keep to use old version MinerU, as the new version MinerU tends to split a whole figure into several subfigures, which destroy the compelete semantic. However, it seems the updation of MinerU leading to old version model checkpoints are unavailable.
If you find the correct model weights cannot be downloaded by using the `download_models.py` script, you can directly download all models weights from this [Huggingface Repo](https://huggingface.co/jiaxianustc/BioMiner-MinerU-Model) and save the model weights to your MinerU cache path.

#### 2. Install vllm env
```
conda env create -f vllm_environment.yml
conda activate vllm_py310
```

## Usage of BioMiner

Our codes support users to choose MLLM they want to use.

If you want to use BioMiner-Instruct, you do not need to further modify the config file. You should deploy BioMiner-Instruct locally and **we recommend at least two A800 80G GPUs**.

Otherwise, if you want to use closed-source MLLMs through api, you should config the `api_key`, `base_url`, `text_mllm_type`, and `vision_mllm_type` in config file `BioMiner/config/default_open_source.yaml` for calling MLLM api. At this time, **you only need one GPU, such as 4090 24G**.

Due to the copyright of papers, here, we only take two open access papers as an example to show the usage:

### Start biominer server
```
# Our codes support multi-gpu inference by deploying models as servers to accelerate inference
# We run the demo experiments on 4 A800 80G GPUs
# We recommend to deploy servers at background using tools such as tmux

export PYTHONPATH=./

conda activate BioMiner
python scripts/mineru_server.py # at tmux window 0 or use nohup
python scripts/moldet_server.py # at tmux window 1 or use nohup
python scripts/ocsr_server.py # at tmux window 2  or use nohup

conda activate vllm_py310 # start this server when using BioMiner-Instruct, otherwise skip 
bash scripts/run_local_vllm_server_biominer_instruct.bash # at tmux window 3 or use nohup
```

### Interactive User Interface
Currently, we provide interative user interface for non-command deployment and better result analysis.

Refer [README](BioMiner_UI/README.md) for more instructions.

### Run inference given a pdf file
```
export PYTHONPATH=./
python3 example_open_source.py --config_path=BioMiner/config/default_open_source.yaml --pdf=example/pdfs/68_6r8r.pdf --output_dir=./tmp_output/demo_68_6r8r
```

### Run inference given a directory contains pdfs
```
export PYTHONPATH=./
python3 example_open_source.py --config_path=BioMiner/config/default_open_source.yaml --pdf=example/pdfs --output_dir=./tmp_output/demo_directy
```

### Parameter Descriptor

Both two version takes the following input:
- **config_path**, the path of config file, we provide a default config
- **pdf**, the path of the pdf file or the pdf directory. 
- **biovista_evaluate**, if the pdfs are in biovista (have labels), enable biovista evaluation
- **--output_dir**, the result output directory

## Evaluation on BioVista and Result Reproducation

### Evaluation of Two End-to-end Tasks:
- 1. Downloading the BioVista papers, and save the 450 papers of BioVista testing set in the `example/pdfs` directory
- 2. Downloading the six BioVista dataset, and unzip in the `BioVista` directory
- 3. Adding `--biovista_evaluate` in the command line, running:
```
export PYTHONPATH=./
python3 example_open_source.py --config_path=BioMiner/config/default_open_source.yaml --pdf=example/pdfs --biovista_evaluate --output_dir=./tmp/test_biovista_upgrade
```

1. We first inference the result:
    - Molecule Detection
    ```
    # Taking YOLO as an example (BioMiner use MolDetV2)
    python3 BioVista/component_infernece/molecule_detection/moldetect_inference_batch.py
    ```

- OCSR
    ```
    # Taking MolScribe as an example (BioMiner use MolGlyph)
    python3 BioVista/component_infernece/ocsr/molscribe_inference_batch.py

    ```
    # Run BioMiner Structure Extraction Agent
    python3 BioVista/component_infernece/full_coreference/coreference_inference_batch_with_index_split_image_layout.py

    ```
    # Run BioMiner Structure Extraction Agent
    python3 BioVista/component_infernece/markush_enumerate/markush_zip_inference_batch_with_index_layout.py
