Among other procedures, Scribe uses the following to verify the accuracy of OCR. If you use any outside service to provide OCR, we recommend that you use this procedure to find and correct errors within files. OCR standards.
The goal of OCR modification is to create a Word file meets OCR standards and matches the source materials. Checks will be performed in both the point document (Microsoft Word) and Sublime Text.
If verifying the file only to determine if the file supplied by the vendor is correct, files may be rejected at any point in which an unacceptable number of errors is found. If correcting the file while verifying, the benchmark rate for OCR modification is 100,000 characters per hour (86,000 characters per hour for complex files, such as files with extensive Hebrew usage).

Procedure
Note: Searches may yield false positives, finding aspects that correctly match the source materials.
Run SAI Tools for File Prep
Run the SAI’s Rendering and List Leaders tools in Word.
Spellcheck

Optimal settings for spellchecks are listed here.
Page IDs
Page IDs should be formatted as {~?~PG: @#@} (where “#” is the page number) and connected to text or an image callout; they should not be in their own paragraphs.
Paragraph Integrity
Check the file to determine if any paragraphs have been improperly broken or combined.
Spot check Page IDs that occur at the beginning of paragraphs against the source.
Check that paragraph integrity has been maintained across pages.
Check that soft returns are not present.
Check that paragraphs have not been broken to insert content such as images, tables, or sidebars.
Character Rendering
Compare the Word document with the source to confirm that all character rendering (e.g., italics, small-caps, bold) has been applied.
Check for non-ScML styles that have been applied to characters to apply rendering.
Footnotes and Endnotes
Check that footnotes appear in the document using Microsoft Word’s footnotes feature; Check that they match the source.
Check that endnotes appear in the document using Microsoft Word’s endnotes feature; Check that they match the source.
Image Callouts
Check that image callouts and associated captions are placed at the nearest paragraph break after the content appears in the source.
Check that images use the format {~?~IM: insert projectname-p#.jpg here.} where “#” is the page number on which the image appears.
Check that the callouts match the names of the image files.
Check that figure captions appear as text.
