👑 GLiNER: Generalist and Lightweight Model for Named Entity Recognition

GLiNER is a Named Entity Recognition (NER) model capable of identifying any entity type using a bidirectional transformer encoder (BERT-like). It provides a practical alternative to traditional NER models, which are limited to predefined entities, and Large Language Models (LLMs) that, despite their flexibility, are costly and large for resource-constrained scenarios.

🛠 Installation & Usage

To provide instructions on how to install the GLiNER model from source, you can add steps for cloning the repository and installing it manually. Here’s how you can incorporate those instructions:

🛠 Installation & Usage

To begin using the GLiNER model, you can install the GLiNER Python library through pip, conda, or directly from the source.

Install via Pip

!pip install gliner

Install via Conda

conda install -c conda-forge gliner

Install from Source

To install the GLiNER library from source, follow these steps:

Clone the Repository:

First, clone the GLiNER repository from GitHub:
```
git clone https://github.com/urchade/GLiNER
```
Navigate to the Project Directory:

Change to the directory containing the cloned repository:
```
cd GLiNER
```
Install Dependencies:

It's a good practice to create and activate a virtual environment before installing dependencies:
```
python -m venv venv
source venv/bin/activate   # On Windows use: venv\Scripts\activate
```
Install the required dependencies listed in the requirements.txt file:
```
pip install -r requirements.txt
```
Install the GLiNER Package:

Finally, install the GLiNER package using the setup script:
```
pip install .
```
Verify Installation:

You can verify the installation by importing the library in a Python script:
```
import gliner
print(gliner.__version__)
```

🚀 Basic Use Case

After the installation of the GLiNER library, import the GLiNER class. Following this, you can load your chosen model with GLiNER.from_pretrained and utilize predict_entities to discern entities within your text.

from gliner import GLiNER

# Initialize GLiNER with the base model
model = GLiNER.from_pretrained("urchade/gliner_mediumv2.1")

# Sample text for entity prediction
text = """
Cristiano Ronaldo dos Santos Aveiro (Portuguese pronunciation: [kɾiʃˈtjɐnu ʁɔˈnaldu]; born 5 February 1985) is a Portuguese professional footballer who plays as a forward for and captains both Saudi Pro League club Al Nassr and the Portugal national team. Widely regarded as one of the greatest players of all time, Ronaldo has won five Ballon d'Or awards,[note 3] a record three UEFA Men's Player of the Year Awards, and four European Golden Shoes, the most by a European player. He has won 33 trophies in his career, including seven league titles, five UEFA Champions Leagues, the UEFA European Championship and the UEFA Nations League. Ronaldo holds the records for most appearances (183), goals (140) and assists (42) in the Champions League, goals in the European Championship (14), international goals (128) and international appearances (205). He is one of the few players to have made over 1,200 professional career appearances, the most by an outfield player, and has scored over 850 official senior career goals for club and country, making him the top goalscorer of all time.
"""

# Labels for entity prediction
labels = ["Person", "Award", "Date", "Competitions", "Teams"]

# Perform entity prediction
entities = model.predict_entities(text, labels, threshold=0.5)

# Display predicted entities and their labels
for entity in entities:
    print(entity["text"], "=>", entity["label"])

Expected Output

Cristiano Ronaldo dos Santos Aveiro => person
5 February 1985 => date
Al Nassr => teams
Portugal national team => teams
Ballon d'Or => award
UEFA Men's Player of the Year Awards => award
European Golden Shoes => award
UEFA Champions Leagues => competitions
UEFA European Championship => competitions
UEFA Nations League => competitions
European Championship => competitions

🔌 Usage with spaCy

GLiNER can be seamlessly integrated with spaCy. To begin, install the gliner-spacy library via pip:

pip install gliner-spacy

Following installation, you can add GLiNER to a spaCy NLP pipeline. Here's how to integrate it with a blank English pipeline; however, it's compatible with any spaCy model.

import spacy
from gliner_spacy.pipeline import GlinerSpacy

# Configuration for GLiNER integration
custom_spacy_config = {
    "gliner_model": "urchade/gliner_mediumv2.1",
    "chunk_size": 250,
    "labels": ["person", "organization", "email"],
    "style": "ent",
    "threshold": 0.3,
    "map_location": "cpu" # only available in v.0.0.7
}

# Initialize a blank English spaCy pipeline and add GLiNER
nlp = spacy.blank("en")
nlp.add_pipe("gliner_spacy", config=custom_spacy_config)

# Example text for entity detection
text = "This is a text about Bill Gates and Microsoft."

# Process the text with the pipeline
doc = nlp(text)

# Output detected entities
for ent in doc.ents:
    print(ent.text, ent.label_, ent._.score) # ent._.score only available in v. 0.0.7

Expected Output

Bill Gates => person
Microsoft => organization

📊 NER Benchmark Results

ONNX convertion:

To convert previously trained GLiNER models to ONNX format, you can use the convert_to_onnx.py script. You need to provide the model_path and save_path arguments to specify the location of the model and where to save the ONNX file, respectively. Additionally, if you wish to quantize the model, set the quantize argument to True (it quantizes to IntU8 by default).

Example usage:

python convert_to_onnx.py --model_path /path/to/your/model --save_path /path/to/save/onnx --quantize True

To load the converted ONNX models, you can use the following code snippet:

from gliner import GLiNER

model = GLiNER.from_pretrained("path_to_your_model", load_onnx_model=True, load_tokenizer=True)

The load_onnx_model argument ensures that the GLiNER class recognizes that it should load the ONNX model instead of a PyTorch model. Setting the `load_tokenizer`` argument to True loads the tokenizer from your model directory, including any additional tokens that were added during training.
