The computer program Fritz actually has algorithms to imitate a human's analysis. It's one of my favorite tools to improve my game, since it searches databases of master-level games to find games that progressed in the same way and also gives "human-like" annotations. Here's an example PGN[1] from one of my games (NAG[2] has been converted to Unicode for the sake of clarity)
