@nlpjs-neo/lang-eu

Part of NLP.js Neo, a refreshed and maintained fork of axa-group/nlp.js. The packages are ESM only, written in TypeScript, and require Node.js 22.12 or later.

Introduction

@nlpjs-neo/lang-eu is the Basque language plugin of NLP.js Neo. It bundles the tokenizer, the stemmer, the stopwords, the normalizer and, where the language has one, the sentiment dictionary, and registers them in the container for the eu locale.

Installation

pnpm add @nlpjs-neo/lang-eu

Example of use

import { containerBootstrap } from '@nlpjs-neo/core';
import { Nlp } from '@nlpjs-neo/nlp';
import { LangEu } from '@nlpjs-neo/lang-eu';

const container = await containerBootstrap();
container.use(Nlp);
container.use(LangEu);

const nlp = container.get('nlp');
nlp.settings.autoSave = false;
nlp.addLanguage('eu');
// add your documents and answers, then train
await nlp.train();

From a conf.json, name the plugin in the use list:

{
  "use": ["Basic", "LangEu"]
}

The classes can also be used on their own:

import { StopwordsEu } from '@nlpjs-neo/lang-eu';

What it exports

| Export | What it is | | ------ | ---------- | | LangEu | the plugin that registers everything below in a container | | StemmerEu | reduces a token to its stem | | StopwordsEu | removes the words that carry no meaning for the classification | | TokenizerEu | splits a text into tokens | | NormalizerEu | lowercases the text and strips accents | | SentimentEu | the sentiment dictionary of the language |

node-nlp-neo and @nlpjs-neo/lang-all already include this package, so install it directly only when you assemble the container yourself.

See Language support for what each locale supports.
