Entity extraction
I would like autotools to do entity extraction on pieces of text. Like detect phone numbers, email addresses and names of places and people to name a few.
You can search online for "Phone number Regular Expressions" for example to find regex's to use in AutoTools Regex to match a phone number.
There's too many variations worldwide on phone numbers, addresses, etc. to make say an easy drop down menu to just select "phone numbers".
Depending on what country you're in guaranteed there's regex's out there to match what you need, and when you find some - just drop them into AutoTools Regex to test them out until you find what works for you.
Probably a good way to learn about Regular Expressions as well, to better utilize AutoTools Regex action.
