are there already programs/projects to calculate a rating
by looking at the moves of a particular game ?

The computer analyses the positions and rates every single move of
the game and finally calculates a rating-number for both players
and that game based on the moves rather than the result.

The program will be optimised so that the overall rating
difference of a players reflect the expectation value
of his points in a tournament.


Rating is not an absolute value, it's establishing differences in
strenght, or even better, predicting win/lose scores.
The value depends on the pool of players, not on the strenght of
individual moves.
A 2100 player in pool one can be as strong as a 1900 player in pool two.

Programs that use rating features use personalities or values that have
been tested against players with a certain rating and see how much the
results differ from their actual rating. Sometimes ratings come close to
your own OTB ratings, but more than often they don't, because they're
tested against players from other pools.
