Pillow is a wrapper for PIL - Python Imaging Library. You will need this library to read in image as the mask for the word cloud. wordcloud can be a little tricky to install. If you only need it for plotting a basic word cloud, then pip install wordcloud or conda install -c conda-...
In the above code, set the width and height of the image to 800 pixels and the background_color to white. You can alsoset stopwordsto an empty list, which means that you will not remove any common words from the text. Finally, set the min_font_size to 10. Displaying the Word Cloud...
One way would be to split the document into words by white space (as in “2. Split by Whitespace“), then use string translation to replace all punctuation with nothing (e.g. remove it). Python provides a constant calledstring.punctuationthat provides a great list of punctuation characters....

By looking at the schematic above, we can structure the hybrid search workflow into distinct steps, allowing both semantic and keyword searches to operate in parallel: Data cleansing & preprocessing Keyword Search: Requires robust data cleaning (e.g., using NLP tools to remove stopwords) to ensur...

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
