Today is the first day I tried Bing Translator for myself. Not because I wanna use it for my translation work, but just to test is it reliable translation robot or not.
Still, real human English Korean translator is far better than robot.
Anyway, here is a simple translation work performed at Google Translate and Bing Translator.
I wrote: 난 사용해
Google Translate result : I'm using
Bing Translator: I used
So.. see it? Both are differ in meaning. That's the reason why you need a real human translator who did not use machine or translation tools in their work.
