| Your challenges are almost immaterial compared with what goes into something like Siri. First you need a way to get input. Is that a text input or do you need voice to text? Google and others can provide a voice to text API to help along here at least at first. Second you need to make that text meaningful. But what the heck is "meaningful" in this context? Generically running an NLP over this is going to get you sentence structure, etc which may or may not be all you need. Essentially you need to take this text and turn it into a graph of decisions which can then be executed. Basically distill the sentence "send a text to Josh saying hi" To a graph that might have a branch like:
Action -> Send -> SMS -> ("joshbsmith@yahoo.com", "hi") Categorization is hard. If you can get it reasonable (85% solution) then you'll be pretty good. This is how Siri essentially works. Things to consider: - "How long is the Titanic" is this referring to a movie or the boat? - "Where is Aaron's?" Is this referring to the furniture store chain, a friend in your contact list or even the street name? Source: been looking into this a ton. Wrote this during a hackathon: http://devpost.com/software/sim. So this is all very possible :) |
