Man is to woman as king is to

How would a computer answer these questions?

I made this app to find out. Play with it, it will sometimes come to weird conclusions.

All the standard stuff it agrees with most people (Rome is to Italy as Paris is to...will generate france).
but...

Man is to Woman as Software is to freeware?
President is to Country as software is to computer?

Find any cool (or crazy/unexpected) results? please mail them to remko66@gmail.com

How does it work(sorry some nerd speak after this...if you don't understand, its oke...just enjoy the app)

I made a word vector database of about 400 thousand english words. (CBOW method). I substract the first to word vectors and add the third.

btw...I love to play with NLP and other AI stuff....any ideas for good apps always welcome..(can also hire me for boring apps btw).
