... K=(1-C)t+C(1-u)p (2) The relationship between the real and the ob- served performance is derived from 1 and 2: x=K-C(1-u)p+Cu Since only K and C are known (or approxi- mately estimated) we can ... bounds for t, u and p, and see in which range is x. Since all variables are probabilities, they are bounded in [0, 1]. We also can assume 2 that K > C. We can use this constr...

We provide a necessary condition and a sufficient condition for the probabilistic exten- sion of parsing strategies. These ... ex- amples of parsing strategies are the standard con- structions of top-down PDAs (Harrison, 1978), left- corner PDAs (Rosenkrantz and Lewis II, 1970), shift-reduce PDAs...
