Abstract Word alignment Translational dictionary
In this paper we demonstrate the semantic
feature machine translation (MT) system
as a combination of two fundamental
approaches, where the rule-based side is Desperate to hold onto power , Pervez
supported by the functional model of the Musharraf has
Russian language and the statistical side discarded Pakistan ' s constitutional
framework and
utilizes statistical word alignment. The declared a state of emergency .

Features of Machine Translation System
dictionary entries contain semantic attributes of the Russian words the MT system is automatically extendable through acquiring new par-
each entry represents a sample of a context extracted using statistical allel corpora and applying the method of word alignment with semantic
