How It Works
Amazon Comprehend uses a pre-trained model to examine a document or set of documents to gather insights about the document set. The model is continuously trained on a large body of text so that there is no need for you to provide training data. Except for the DetectDominantLanguage operation, Amazon Comprehend can examine documents in these languages:
-
English
-
Spanish
Amazon Comprehend provides the following operations:
-
Single-Document Processing—You call Amazon Comprehend with a single document and receive a synchronous response.
-
Multiple Document Synchronous Processing—You call Amazon Comprehend with a collection of up to 25 documents and receive a synchronous response.
-
Asynchronous Batch Processing—You put a collection of documents into an Amazon S3 bucket and start an asynchronous operation to analyze the documents. The results of the analysis are returned in an S3 bucket.
