I consult for a taxi company that uses the stoic system to track movements of cars on a 24/7 basis.
They have a department just to pore through the stoic data to detect drivers mischief.
I have been considering deploying an expert system maybe done with prolog(using my 13 years old cs theory).
Anyone who has tackled such a problem before.
