Welcome to the world of language detection! In this guide, we will explore how to use the NB-NORDIC-LID models designed specifically for identifying languages within Nordic texts, including several Sámi languages. With the help of Fasttext, you can efficiently detect languages in your text-based applications.

Understanding the Models

The NB-NORDIC-LID repository features two main models:

• nb-nordic-lid: Identifies the 12 most common languages in the Nordic countries plus English.
• nb-nordic-lid.159: Extends the language identification capabilities to 159 languages worldwide.

Both models come in large and small (quantized) versions, allowing for flexibility based on your application requirements.

Setup Instructions

To get started with these models, follow these simple steps:

1. Ensure you have Python installed on your system.
2. Install the required packages using pip:

pip install fasttext huggingface-hub

3. Download the models from the Hugging Face repository. You can use the following code snippets:

from huggingface_hub import hf_hub_download
import fasttext

model_name = "nb-nordic-lid.ftz"
model = fasttext.load_model(hf_hub_download("NbAiLab/nb-nordic-lid", model_name))

Making Predictions

Once the model is downloaded and loaded, you can start predicting languages:

text = "Debatt er bra og sunt for demokratier, og en forutsetning for politikkutvikling."
result = model.predict(text, threshold=0.25)
print(result)  # Output will be the predicted language

Analogy for Understanding the Model

Think of the NB-NORDIC-LID models as master translators at a bustling international airport. Just as airport staff can quickly identify languages spoken by travelers and guide them to their destinations, these models categorize the languages of text entries. The nb-nordic-lid is like a specialist who knows the 12 most common languages of a region, while the nb-nordic-lid.159 is akin to a polyglot who can manage conversations in 159 different languages! The bigger the repertoire, the more languages it can handle efficiently and accurately.

Troubleshooting Tips

If you encounter issues, consider the following troubleshooting steps:

• Ensure your Python environment contains all necessary libraries.
• Verify that the model file is correctly downloaded from Hugging Face.
• Check if the imported model matches the one you are trying to use in terms of naming and path.
• If results seem inaccurate, try adjusting the prediction threshold.
