Artificial Intelligence with Java

G

Giovanni R.

I'd like to create an application using Java where users give a phrase in input and the application says if it's a /negative/ or /positive/ phrase.

Where should I start?
Has AI already solved this kind of problems?

Thanks.

Is the following sentence negative or positive and why?

»Nella predisposizione dei turni di ferie, nei limiti delle
esigenze di servizio, viene data precedenza ai lavoratori
disabili rientranti nelle categorie di cui alla legge
12.03.1999 n. 68; per il restante personale si tiene conto
delle richieste degli interessati in rapporto alla loro
situazione familiare e alla loro anzianità di servizio.«

Consider that the same phrase, "good job!", can mean it was a good job or
it was a terrible job depending on the context. (Ex.: In Star Wars Attack
of the Clones when Anakin and Padme have been captured and are chained up
next to Obi-Wan, he asks what they're doing here. Anakin says they came
to rescue him. Cue "good job!".)

The day AI can reliably tell when "good job!" is positive or negative is
the day we can all stop worrying about keeping *our* jobs -- one way or
another.

The phrase you want to feed into a search engine is "natural language
processing".


Probably (or to put it another way -- I doubt whether AI is necessary):
depending on what you mean by negative or positive: for instance is "<some
name> is a <some insult>" negative (because of the insult) or positive (because
it makes a positive statement) ?

As an exercise, consider what part of the problem /wouldn't/ be solved by
testing whether the phrase contained the word "not" (including contractions).
