Vowpal Wabbit (Fast Online Learning) by John Langford.
From the website:
There are two ways to have a fast learning algorithm: (a) start with a slow algorithm and speed it up, or (b) build an intrinsically fast learning algorithm. This project is about approach (b), and it’s reached a state where it may be useful to others as a platform for research and experimentation.
I rather like that!
Suspect the same is true for subject identity recognition algorithms.
People have fast ones that require little or no programming. 
What it will take to replicate such intrinsically fast subject recognition algorithms in digital form remains a research question.
