What is stopwords-iso?

Stopwords are common words that are usually filtered out in natural language processing tasks because they carry less meaningful information. This package is useful for text preprocessing in various languages.

What are stopwords-iso's main functionalities?

Retrieve stopwords for a specific language

This feature allows you to retrieve an array of stopwords for a specific language. In this example, we retrieve the stopwords for English.

const stopwords = require('stopwords-iso');
const englishStopwords = stopwords['en'];
console.log(englishStopwords);

Retrieve stopwords for multiple languages

This feature allows you to retrieve stopwords for multiple languages at once. In this example, we retrieve stopwords for English, French, and German.

const stopwords = require('stopwords-iso');
const languages = ['en', 'fr', 'de'];
const multiLangStopwords = languages.reduce((acc, lang) => {
  acc[lang] = stopwords[lang];
  return acc;
}, {});
console.log(multiLangStopwords);

Check if a word is a stopword

This feature allows you to check if a given word is a stopword in a specified language. In this example, we check if 'the' is an English stopword and if 'maison' is a French stopword.

const stopwords = require('stopwords-iso');
const isStopword = (word, lang) => stopwords[lang].includes(word);
console.log(isStopword('the', 'en')); // true
console.log(isStopword('maison', 'fr')); // false
