About

Stop words are words that don't carry much meaning, and are typically removed as a preprocessing step before text analysis or natural language processing. This crate contains common stop words for a variety of languages. This crate uses stop word lists from Stopwords ISO and also from NLTK.

Usage

Using this crate is fairly straight-forward:

// Get the stop words
let words = stop_words::get(stop_words::LANGUAGE::English);

// Print them
for word in words {
    println!("{}", word);
}

The function get will take either a member of the LANGUAGE enum or a two-letter ISO language code as either a str or a String type.

You can find a complete example of how to read in a text file and remove stop words here.

Constructed Language Availability

We also support some constructed (fictional/fantasy) languages! Expand the table below to see a comprehensive description. ChatGPT was used to generate these lists quickly, so they are incomplete and approximate. Help welcome! To use these languages, add the constructed feature.

The following prompt was used with the Mar 14, 2023 version of ChatGPT:

Please give me one list of 20 stop words for each of the following languages: Sindarin, Quenya, DOthraki, Na'vi, 
Dovahzul, Klingon, and High Valyrian. I'd like the lists to be formatted as follows:
Sindarin
1. [word goes here]
2. [word goes here]
...
20. [word goes here]
Quenya
1. [word goes here]
...

And so on
