I need to recognize a complex chemichal names from a scanned document (pdf). They contain special characters and are written in a table format. I also have an Excel document that contains ALL possible names (I would say rows because there are no combinations) that I may encounter during scanning. Is there a way to create ligatures (so the Finereader will recognize an entire row instead of dissecting it into separate characters)? I tried creating a user dictionary but Finereader does not treat it as a one row.

The only way to create ligatures is to use "user pattern training". In FineReader, go to Tools -> Options -> Read tab (changes slightly depending on FR version) and enable User pattern training. During training extend your box to include several combined characters, thus creating a ligature.

The formulas recognition using this method is tough but may be possible.

I have done this many times in my work at www.wisetrend.com. I am a former ABBYY support employee and current integrator and OCR consulting specialist. I will be glad to help if you need more specific assistance.

  • Thank you! Should I always use only user pattern that I've trained or a combined mode with a built-in patterns? Once I'm in a verify mode I correct the same mistake again and again (30Mg Name changes to 3OMgName). Is there a way to make finereader memorise it? – Yodo May 03 '17 at 09:30
