PDFs: Fixing Incorrectly Tagged Text after OCR (Text Recognition)

Situation:

You have a textbook chapter that was scanned as a PDF (image).  After processing the scan with OCR (optical character recognition) in Acrobat Pro to convert the image into text, you run the auto-tagging function.  But you notice that the caption text accompanying one of the figures has been incorrectly tagged as a figure.  You want to fix the caption so that it is tagged as text.

Solution: 

You can fix the problem by adjusting the object's properties to add the correct text and correctly convert the tag to paragraph text, and then into a caption.  Here's how to do it:

1. With your document open in Acrobat Pro, open the Accessibility Tags panel and navigate to the problematic caption. 
   In the example below, we can see that the caption is tagged as an image instead of as text.
   
   
   
   
2. To edit and change this error: in the Tags panel, right-click on the Image object (which sits inside the Figure tag), and select "Properties" from the drop-down menu.
   
   
   
   
   
3. In the pop-up window that appears, we will feed Acrobat the caption text by doing the following - in the Tag tab:
   
   A. In the "Type" field, select "Paragraph" from the drop-down menu.
   B. In the "Actual Text" field, type or paste in the caption text.
   C. Set the Language to English.
   
   
   
   Next, switch over to the Content tab and make sure the "Language" field is set to "English".  Hit the "Close" button to save your changes.
   
   
   
   
4. Now we need to re-tag the caption so that it's not tagged as an image.  First, we'll need to delete the current incorrect Image tag.
   From within the Tag panel, right-click on the image tag and select "Delete Tag" from the drop-down menu.
   
   
   
   
   
5. Next, open the Reading Order tool - (this can be found within All Tools > Prepare for accessibility.
   I have it added as a short-cut on my tool menu, outlined in blue in screenshot below).
   With your mouse, click and drag around the caption text to select it. Then click on the "Text / Paragraph" button in the Reading Order tool window. 
   
                 
   
   This will remove the caption text from the Figure tag, and transfer it into a paragraph tag (<P>) in the Tag panel.
   
   
6. You'll need to drag this new <P> tag up so that it sits directly underneath the affiliated image.  Simply grab it with the mouse and drag it into place within the Tags panel.
   
   
   
   
7. We can now change the <P> tag into a <Caption> tag. 
   In the Tags panel, simply click on the <P> tag to access the editing field, and replace the "P" by typing in the word "Caption", and the transformation is done!
   
   
   
   
8. Finally, we'll delete the empty <Figure> tag. 
   In the Tags panel, right-click on the old, empty <Figure> tag, and select "Delete Empty Tags" to get rid of it.
   
   
   
   Voila! You have fixed the problem - hooray!
