I would like to make a piece of software able to regognize whether a sentence is positive or negative.
Is there any Lexical Analysis libraries arround?
I don't really know where I should start.

try google, I did a quick search and found a few links. What do you mean when you say the sentence can be positive or negative ?

For example if the word "good" shows up, the sentence is positive. If the word 'bad" shows up the sentence is negative. Thats a very simple example, but I guess it gives you the idea.

This field is called Natural Language Processing, and it's an incredibly complex subject - not only do you have to parse the words that are positive/negative, but you need to parse modifiers, too (e.g. "Something is not bad").
As usual Wikipedia has some information. If you're just having a bit of fun with this, I suggest trying out a simple system (e.g. recognize "good" and "bad" and "not") and build it up.
