I have a large spreadsheet with thousands of rows/columns of text. Some are saying essentially the same thing but in different ways.
When you enter a natural language question Wolfram Alpha makes a good stab at 'understanding' what you enter. For example, 'how far is the sun from the earth' has the same answer as 'what is the distance from the earth to the sun'. Mathematica converts it to [Sun][ Distance from the Earth].
Does MMA have built-in (undocumented) functions that would allow us to compare text strings and test for equivalence (or fuzzy equivalence)?
