Welcome to your friendly guide on how to harness the Stanza model for token classification in the Welsh language (cy)! Stanza is a powerful suite of tools designed for linguistic analysis, making it easier to dive deep into text data. Whether you are dealing with syntactic analysis or entity recognition, this article has got you covered.

What is Stanza?

Stanza is a collection of state-of-the-art tools for Natural Language Processing (NLP) that supports numerous human languages, including Welsh. It transforms raw text into a structured format, enabling you to perform various analyses efficiently.

Getting Started with Stanza

The first step is to install Stanza and set up the Welsh language model. Here’s how you can do it:

• Ensure you have Python installed on your machine.
• Open your terminal or command prompt.
• Run the following command to install Stanza:

pip install stanza

• Download the Welsh model:

import stanza
stanza.download('cy')

• Initialize the Stanza pipeline:

nlp = stanza.Pipeline('cy')

Understanding the Code: An Analogy

Think of Stanza as a chef in a kitchen where the primary ingredient is language. Each of the steps you’ve taken is analogous to preparing a dish:

• Installing Stanza is like gathering all your cooking utensils and ingredients.
• Downloading the Welsh model is akin to selecting a specific recipe—you’re choosing the Welsh dish to cook!
• Initializing the pipeline is similar to turning on your stove and preheating it, getting ready to mix flavors and create something delightful.

Using Stanza for Token Classification

Now that you have your Stanza kitchen set up, it’s time to start cooking! Here’s a simple example to perform token classification:

doc = nlp("Mae Cymru yn wlad hardd.")
for sentence in doc.sentences:
    for word in sentence.words:
        print(f'Word: {word.text}, Lemma: {word.lemma}, POS: {word.xpos}')  

This example takes a Welsh sentence and processes it to extract words, lemmas, and parts of speech (POS).

Troubleshooting

While using Stanza, you may encounter a few hiccups. Here are some common troubleshooting tips:

• **Issue:** Model download fails.
  **Solution:** Ensure your internet connection is stable and try again.
• **Issue:** Errors in execution.
  **Solution:** Check for syntax errors in your code and ensure Stanza is correctly installed.
• **Issue:** No output from model.
  **Solution:** Confirm that the input text is in Welsh and formatted correctly.
