I am trying to detect whether the sentence I have is a question or no.

I started by thinking about writing keywords, then look-up everytime for those keywords. But I don't think that's enough. 

qWords= ["what","when","where","how"]    

def isQuestion(w):
    return any(item for item in w.split(" ") if item.lower() in qWords)

Is there any way to get insight from a question, like extracting places, times ... etc

sentence= "What is the weather in London today".
  • It's a question
  • Asking about weather
  • Place: London
  • Time: today

If I train words by simply looking in senetence for key words. I would face problem like: 

 "The rainy weather, is what I love most about London"

Is there any recommended approach! or Should I try to train all the words like I did in this simple example for both places, times, .. If it's the case, where can I find data set of these words.

    You can also try to analyze the word order. – Danil Gaponov Oct 30 '14 at 14:16
