Re: All These Files - Am I Thinking About This Right?

the weakest link is OCR. But if you are only interested in keywords (as opposed to the complete text) then even if OCR's output is incomplete, there are probabilistic methods to complete (and even validate) the OCR'd keyword. If you want to adjust these methods to your context then you need to manually convert some representative set of documents to text (or manually correct OCR's output for those documents only) and feed that to your methods. That assumes (enough) documents belong to a single context, e.g. legal or spy reports, I guess.

Once you have the document text, there are various open-source search frameworks to use, as marto mentions, and it will be free-wheeling from there on.

What I would not do is form the filename from keywords. I would rather give each file a unique number id. Then use your already implemented search engine to search. If your documents are already indexed on some keywords, e.g. Report 5,5/12/12,ABC.vs.XYZ then, optionally, process it and insert that into DB too to be used to enhance your search engine.

"...Once you have the document text, there are various open-source search frameworks to use... Elasticsearch has plugins such as fscrawler to deal with all that for you.	[reply]

Cool then. It uses Tesseract too. Though, I do not know how effective an automated solution will be as opposed to manually tuning or re-training Tesseract for scanned, old documents.	[reply]

Nothing to stop you tweaking Tesseract to your heart's content.	[reply]
