convert scanned pdf into searchable pdf - Alfresco Community 5.2

anuradha1

Hi,

I am using alfresco for a long time. I scanned around 100,000 documents & uploaded into alfresco. But suddenly i faced a problem because it can't be read using it's content. If i scanned a document using a scanner having ocr then it can be. But, i don't have ocr on every scanner so i need to integrate OCR module into alfresco. I tried tesseract ocr & simple ocr, but both did not worked.

If anyone knows, plz tell me another way to do this or correct way to integrate tesseract-ocr or simple-ocr
I need to convert all uploaded document into searchable pdf also.

Thanks

Hi anuradha madhushani

Do you know this addon?

GitHub - keensoft/alfresco-simple-ocr: Simple OCR action for Alfresco

You can configure a rule which it executes the OCR action from this addon.

Regards.

Thank you for all who helps to me. I did it with simple-ocr for my Linux installation. But now i need to do the same with an alfresco windows installation. Anyone knows a way to do that??

Any help will be appreciated.

J'ai le méme probléme dans Windows ! comment je peux résoudre le probléme ??

hi @anuradha1,

I am currently working on alfresco PDF OCR, I have installed the files as per the thread on Github and got the same result as the above image.

Now I am stuck at this point and don't know what to do further.

So I want to know that did you installed this on the windows platform and did it work?

If worked then can you tell me the steps which you have followed and is there any other addon for making pdf searchable on alfresco?

My system configuration is

Alfresco community edition 5.2
windows 10.

Thanks in advance.
