OCR from Slightly Different PDFs - python-3.x

I am working on a project where i have to extract information from PDF documents. While the documents follow similar format, few documents are slightly different in their format, how do i handle this using python.
I am working with form 483 available on the FDA website.

How can I push Lotus Notes documents with rich text fields and file attachments to a MySQL database?

We are using v9.0.1 and have one application that we must preserve for the time being. I am hoping to expose this database's documents with all content to a MySQL database for which we will develop a web front-end to present the records read-only. I know I can export the data to text files or to XML, but I want to retain the formatting of the rich text fields and the files that have been added to them (there are several per document). I've emailed the documents in an agent to a document management system, but the content of the rich text fields is stripped of any formatting and all the data I output is presented in a plain .txt file, but the attachments are preserved. I am hoping to provide a more elegant solution.
Any ideas will be appreciated.

The Domino router can do rich text to HTML conversion, so if set up properly you won't lose all your formatting -- but you still won't get great fidelity. I used that technique in an archiving product that I built 15 years ago, but it was only "good-enough" fidelity, and it was only for Notes email messages. There would be more to do if you're dealing with application documents. It's been too long, so I can't recall any specific details.
If you can spend money on this, the migration tool from Genii Software will help. Look up their AppsFidelity Migrate product. There may be some other third-party products that you could work with, but this one comes from a company that has been 100% dedicated to dealing with Notes rich text for decades. If you call them, tell Ben that I sent you.

AWS Textract can not recognize the table of the second page of PDF document

I need to extract table information from a billing copy using AWS Textract. It gives me almost perfect results every time but for some PDF document, it does not give me the table results of the second page.
code examples used: AWS Official Documentation
image(JPEG) of first page is
image(JPEG) of second page is
So, AWS gives me the first 20 entries output as CSV. But for the second page of the image the result of CSV is:
and most importantly, I found the same results in a similar type of PDFs which has 21 entries and one entry exists on the second page of PDF. I have already used PyPDF2 to merge pdf pages into one page but doesn't solve my problem. Is there any OpenCV tools do I need to use?
Please suggest to me any possible suggestions for these types of issues.

Extract Keywords from Office Documents with Sharepoint Flow

I am trying to implement a document management system using Sharepoint. One major issue is that colleagues cannot find documents in the current setup (local fileserver). They have asked that we have a system that scans uploaded documents and automatically looks for keywords in them and then populates a "Meta" column.
I have had sort of success with OCR on image files, but getting keywords out of office documents (doc, xls etc.) I have had no success until now.
Is there a way to setup a flow to do this task for me?
any help is much aprechiated.
i tried "Get file metadata" and Azure "Text analysis", but it seems to take the raw data of the files (XML I assume) and returns that the document is to large to analyse.
There is something vague about this requirement - how is a keyword defined in a document?
Therefore, first obvious solution would be to assign keywords for each file upon uploading it. You may create a process for this with flow - have tasks, reminders and so on.
Automating this with OCR first means that you need to user OCR that works with MS flow you have only one choice - ElasticOCR. Then, in your flow
- feed the document content to the ElasticOCR action
- keep in mind that OCR is not 100% accurate
- analyze the generated text content according to your keyword definition
- finally write the meta back to the library in the corresponding columns.
Having worked on a similar requirement, we asked uploaders to publish their documents with a short abstract(column from the content type). The assumption is the abstract contains the keywords and is stored in a multi-line column - making it searchable site wide.

Cannot Extract Images from Lotus Notes using Java API

I am working on a Data extract from a Lotus Notes Application. It stores legal documents which may have attachments and images (not mails). I want to convert notes documents to HTML. While importing the data using java API I am able to extract Text, Attachments etc but when it comes to images I am not able to extract them. I did some research and found about two approaches
1) To extract the document using generateXML() method. But the generated document contains a picture tag which has a referenece of location on Notes Domino server. But I want the image so that it can be included in the HTML document.
2) By extractinh as MIME Entity. When I try to get images using getMIMEEntity("Body") or any other field I do not get any image and It always return null.
There is question (Extract inline images from Lotus Notes using Lotus Notes Java API) which deals with this but It does not answers conclusively and its dormant for a long time.
Please help, I am working on it for a couple of days still I cannot import images. Thanks in advance.
In Lotusscript you can first Extract file to your local system/ Server and than export in excel by using that code below.
' Loop through all attachment/document (By creating attachment object)and save Image to some path on server/local 'system(strSaveasPath)
Call object.ExtractFile( strSaveAsPath)
' Now Activate excel row:column range where you wnat to insert image
xlApp.Range("1:1").Activate
xlApp.ActiveSheet.Pictures.Insert(strSaveAsPath)

I need a web based document viewer in which i can show my tiff images

I need a web based document viewer, open sourced(free), in which i can show my tiff images.
I've gone through so many links however couldn't found any product which supports the tiff format, and can be used within my java code.
I have used Viewone-Pro and it completly fulfill all our needs, however, its not an open source product, so if any other product providing such features available, we would like to use that further.
Please suggest.
