Microsoft Research Asia has just released their latest research achievement: "Computerized Spring Festival Couplets". As long as you provide the first line of the couplet, the system will automatically generate the second line and the horizontal scroll. I just tried it out, and it's indeed quite fun. It seems like it matches word by word. However, the matching is relatively neat. It appears that this year, those who write spring festival couplets for people at the market might need to bring along a laptop.
