natural
general natural language facilities for node
Natural is a JavaScript/Node.js library for processing human text, it handles tokenizing sentences, stemming words, measuring text similarity, and working with an English word database, with TypeScript support included.
Natural is a JavaScript library for Node.js that handles natural language processing tasks. Natural language processing is the field of software that works with human text: breaking sentences into words, understanding word roots, comparing how similar two phrases are, and related operations that help programs make sense of written language.
The README for this project is brief and points readers to separate documentation hosted on GitHub Pages for the full list of features. What the README does confirm is that the library covers a broad range of natural language tasks, includes WordNet (a large English word database from Princeton University used for understanding word meanings and relationships), and includes a German-language word stemmer, which is a tool that strips words down to their root form.
The project supports TypeScript in addition to plain JavaScript, which means developers who prefer typed code can use it without extra workarounds.
The code is released under the MIT license, which permits free use in personal and commercial projects. The WordNet data bundled with the library carries a separate Princeton University license, and the German stemmer component uses a BSD license. All three are permissive and allow broad use.
This project has been around since at least 2011 and has accumulated nearly 11,000 stars on GitHub, suggesting it has been widely used across the Node.js ecosystem for text-processing tasks.
Where it fits
- Tokenize and stem a corpus of customer support tickets to group similar messages together for analysis.
- Build a search feature that matches user queries to documents even when the exact words differ, using Natural's string-similarity tools.
- Look up word meanings and relationships in English using the bundled WordNet database to power a vocabulary app.
- Strip German words down to their root form for a multilingual text-search or categorization feature.
