How to Remove Duplicates from a Tuple in Python Easily

When working with data in Python, particularly in the realm of natural language processing (NLP), encountering duplicates in your dataset can be a common occurrence. In this guide, we'll address a specific question: How can we effectively remove duplicates from a tuple that contains named entities extracted using the SpaCy library?

Understanding the Problem

Imagine you have a block of text from which you’ve used SpaCy's NLP capabilities to extract named entities. After processing the text, your output is a tuple containing various phrases and names. However, you notice that some items in this tuple are duplicates. In our example, you have "MIT" appearing multiple times and the name "Ines Honnibal" separated into distinct words.

Your goal is to create a final output that consolidates these entries: you want to retain only unique phrases while keeping related names grouped together. Let's explore how to achieve this.

Here’s why:

Span objects do not behave like traditional string duplicates.

When you output these Spans, their content is displayed, but they are still distinct objects to Python.

Example Output

For instance, the original output was:

Even after applying the set function to remove duplicates, the output remained unaffected because the individual Span objects were not treated as strings.

The Solution

If your goal is to remove duplicates effectively and ensure that "Ines Honnibal" remains cohesive, here are a couple of methods you can use:

This method ensures that you get the unique entity names, but note that "Ines Honnibal" will still be split into "Ines" and "Honnibal" unless you handle entity recognition differently.

Grouping Related Names

If you specifically want "Ines Honnibal" to show up together, consider adjusting your NLP processing or manually setting conditions to combine names where necessary.

Conclusion

Now you're equipped to tackle duplicates like a pro! Happy coding!
