Summary or Abstract : This dissertation describes some new methods for automated stochastic processing of formal languages and natural languages in particular. This work makes use of stochastic modeling for approximation of the original language L(G) by some stochastic subset $\rm L\sbs\sp\prime$ (G$\sp\prime$, p) where p is the sum of probabilities p(w) of every string w in L, such that G$\sp\prime$ is finite-state and $\rm\Sigma\ p\sb\varepsilon(w) < \varepsilon,$ for all w $\rm\in\ (L - L\sp\prime$), where $\varepsilon$ is some error $\varepsilon > 0$ and L$\sp\prime$ is the characteristic (non-weighted) language of L$\rm\sbs\sp\prime$..
