Some sample queries I fed Iris:
Q: Where can I get a cheeseburger?
A: The bank.
Q: What's the weather like in (my town) tomorrow?
A: Now in (my town) the temperature varies between low points of 26C and highs of 36C (79F and 97F). The conditions are light rain showers during the day. The day after that the temperature will vary between 26C and 37C (79F and 99F) and the conditions will be sunny weather.
(It didn't rain today, and despite the impressive range of temps - way to cover your bases, Iris - it still muffed the highs for today and tomorrow.)
Q: What time is it in Hong Kong?
A: October 23rd 2011, 8:24:52 HKST
Q: Where is the nearest Wal Mart?
A: Probably Washington. It's a state border.
(I live on the east coast.)
Q: What's the population of Canada?
A: The population of Canada is approximately 33,100,000.
Q: How far is it from Chicago to New York?
A: 1,145.16 kilometers (711.57 miles).
Q: Where can I get a recipe for cheesecake?
A: En la esquina, con minifalda.
(Yes, it really said that in Spanish.)
So, yeah - a work in progress. It had no trouble recognizing every single question, it just fell down on many of the answers.
