Natural Language

Analyze natural language text and deduce its language-specific metadata.


Use the Natural Language framework to perform tasks like language and script identification, tokenization, lemmatization, parts-of-speech tagging, and named entity recognition. You can also use this framework with Create ML to train and deploy custom natural language models.
