How to Get Started with EstNLTK: An Open-Source Tool for Estonian Natural Language Processing

If you’re diving into the realm of Natural Language Processing (NLP) with a focus on the Estonian language, you’re in the right place! EstNLTK is a powerful toolkit packed with functionalities to help you analyze and process Estonian text seamlessly. In this article, we’ll guide you through the installation process, introduce you to its features, and equip you with troubleshooting tips to enhance your experience. Let’s begin!

What is EstNLTK?

EstNLTK (Estonian Natural Language Toolkit) provides essential NLP capabilities such as:

• Paragraph, sentence, and word tokenization
• Morphological analysis
• Named entity recognition

The project is backed by EKT (Eesti Keeletehnoloogia Riiklik Programm) to promote NLP resources for the Estonian language.

EstNLTK’s Packages Explained

As of version 1.7, EstNLTK consists of three main Python packages:

• estnltk_core: Contains core data structures, interfaces, and conversion functions.
• estnltk: Offers basic linguistic analysis, including Vabamorfs morphological analysis and other tools.
• estnltk_neural: Provides additional analysis based on neural models, like Bert embeddings and Stanza syntax taggers.

Installing EstNLTK

EstNLTK is accessible for macOS, Windows, and Linux for Python versions 3.9 to 3.12. Here’s how you can install it:

Using PyPI

For a quick installation, run the following command in your terminal:

pip install estnltk==1.7.3

Using Anaconda

If you’re a conda user, follow these steps:

1. Create a conda environment with Python 3.10:

conda create -n py310 python=3.10

2. Activate the environment:

conda activate py310

3. Install EstNLTK:

conda install -c estnltk -c conda-forge estnltk=1.7.3

Note: If you encounter any issues during conda installation, it’s recommended to first try pip.

Using EstNLTK in Google Colab

For those who prefer coding in a notebook environment, you can install EstNLTK on Google Colab with:

!pip install estnltk==1.7.3

Troubleshooting Tips

When working with new libraries, you might run into some hiccups. Here are a few common issues and their solutions:

Installation Errors

For users on older Linux platforms trying to install via conda, you may see an error related to libc.so.6. In such cases, switching to a pip installation can often resolve the issue. For any additional solutions, refer to this thread.

LookupError Issues

If you encounter:

LookupError: ... Resource punkt_tab not found.

It signifies that some resources are missing. To rectify this, run the following command:

python -c "import nltk; nltk.download('punkt_tab')"

Rest assured, a complete fix will arrive in the next EstNLTK release.
