Found some interesting tidbits in their FAQ [0]: "Q: What type of text can Amazon Textract detect and extract?

A: Amazon Textract can detect Latin-script characters from the standard English alphabet and ASCII symbols."

So, English only. But very worryingly is that they're going to keep your companies' documents:

"Q. Are document and image inputs processed by Amazon Textract stored, and how are they used by AWS?

A: Amazon Textract may store and use document and image inputs processed by the service solely to provide and maintain the service and to improve and develop the quality of Amazon Textract..."

"Q. Can I delete images and documents stored by Amazon Textract?

A: Yes. You can request deletion of document and image inputs associated with your account by contacting AWS Support. Deleting image and document inputs may degrade your Amazon Textract experience."

A little late to the comment party, but I was wondering the same. I'm working on a web scrape workflow that's currently using Tika. I'm very interested in to see how well this does in comparison.

I was quite surprised by how powerful and flexible Tika can be, and my use-case was pretty basic: crawling a network drive to index project artifacts like Office docs and media files and pushing them into an Elasticsearch index. Have you found any major problems or shortcomings in your usage?

One small problem is that it sometimes doesn't make newline separations properly. In my use case, I was extracting email addresses from web scrapes - some email addresses would come out as "blah@blah.comRandomWord"

If this can get me tables out of pdf's generated by crystal reports it would be a godsend for testing. This has been a nightmare to try and solve, the best option so far has been adobe cloud but they don't offer an API for that. I'm excited to try it out.

Have you tried e.g. https://tabula.technology , https://pdftables.com , https://pypi.org/project/Camelot/ ?

I have a friend who has also developed a number of applications that use OCR specifically for PDF which uses Tesseract. The Report Miner application does a nice job of locating and extracting PDF tables.

Would love to learn more about the apps your friend developed--currently doing research into different OCR use cases + tech. can you shoot me an email at minh@docucharm.com?
