Question 1

How to train a chatbot with NLP.js from scratch?

Accepted Answer

Install the core package, use the NlpManager to add documents and answers for intents, then train and save the model. The README provides a quickstart example with code for basic greetings and entity extraction.

Question 2

NLP.js or TensorFlow.js for natural language processing?

Accepted Answer

NLP.js is better for modular, multilingual chatbot development with offline capabilities, while TensorFlow.js is suited for custom deep learning models. NLP.js includes built-in connectors and pipelines, reducing boilerplate for bot projects.

Question 3

Does NLP.js support real-time sentiment analysis?

Accepted Answer

Yes, sentiment analysis is included automatically with the NlpManager, supporting negation and multiple languages. Configure the sentiment plugin for custom needs, and it runs offline without external APIs.

Question 4

How to handle custom named entities in multiple languages?

Accepted Answer

Use the NER manager to define enum, regex, or trim entities per language. The README's NER quickstart guide shows how to create and integrate these entities with a corpus for training.

Question 5

What are the limitations of using NLP.js in React Native?

Accepted Answer

The React Native version lacks Chinese support, has an incomplete Japanese stemmer, and cannot load from or save to files—only JSON import/export. It also excludes Excel import, as noted in the limitations section.

Question 6

Can NLP.js integrate with Microsoft Bot Framework easily?

Accepted Answer

Yes, it includes a connector for Microsoft Bot Framework, allowing seamless integration. The quickstart guide covers setting up the connector and handling intents with slot filling for bot logic.

Question 7

How to optimize NLP.js for performance in production?

Accepted Answer

Use caching for trained models, minimize plugins in pipelines, and leverage the export/import features to avoid retraining. Benchmarking docs are available, but performance depends on configuration and hardware.
