What is the “Amazon Comprehend” NLP API?

Amazon Comprehend is one of the NLP APIs that are integrated with WPSOLR’s NLP API extension.

According to Amazon Comprehend documentation:

“Amazon Comprehend uses natural language processing (NLP) to extract insights about the content of documents without the need of any special preprocessing. Amazon Comprehend processes any text files in UTF-8 format. It develops insights by recognizing the entities, key phrases, language, sentiments, and other common elements in a document.

Due to API limits, each document text is truncated to 5000 bytes in UTF-8.”
