Google's ML for rich snippets thinks a quarter is worth 50 cents. http://imgur.com/1nNreR2
Really parsing language for meaning is hard. Sentiment analysis, which seems simpler than this problem, still has relatively poor accuracy.
I could see it perhaps thinning out how much has to be done manually, but I don't see it removing that need entirely.
Plus, the picture is a standing liberty quarter that is nearly 90 years old and pretty much completely out of general circulation.
Other than the subjective statement that quarters are "useful", every fact in the google response is wrong.
Quarters are:
- Worth $0.25 (not $0.50)
- Not the largest. (Dollar coins and half-dollars are larger)
- Made of a blend of copper and nickel. (No silver content for circulating coins)
The picture depicts a standing liberty quarter that is no longer a circulating coin.
It's amazing that Google would put that in production.
What you're seeing is a hyper-accurate snapshot of the exchange rate between "a shave and a hair cut" and "two bits"[1]. Typically you hear about the value over a much longer period of time and the average value of "a U.S. Quarter Dollar" == $0.25.
/snark ;)
[1] "Two bits" -- Noun. Slang term used predominantly by Neo-Victorian communities living in California's Bay Area megalopolis.
