What is the business case ?
1.Create a custom entity recognition model using Amazon Comprehend
You will upload training data to an Amazon S3 bucket, then use Amazon Comprehend to train a custom entity recognition model based on that data.
2.**Conduct a real-time analysis with a custom entity recognition endpoint. Once the model is trained, you will create an endpoint to perform real-time analysis on documents, identifying the custom entities you defined during the training process.
Architecture :-
need to create s3 bucket and hold 2 files document.txt and annotations.txt like below
now launch Amazon Comprehend and create a new model like below.
once you submit this, it takes a few minutes to train the data
you can see progress here
after a few minutes, the model will be trained like below.
create an endpoint for this model to test
In the navigation pane at the left of the page, choose Real-time analysis.
pass this data like below .
finally you learned about AWS comprehend , with this practice lab.
