8 Syntax Probabilistic Model for Assessing the Adequacy of Russian Texts

The methodology of application probabilistic-statistical syntactic model for assessing the adequacy of information text objects was developed. The structure of probabilistic-statistical syntactic model was determined. The technique of probability images formation for compared texts was shown. The amount of information of compared texts estimated by the entropy, and as a measure of semantic proximity of the texts used the mutual information. The sensitivity of mutual information to differences in texts and parts of sentence weights variations was demonstrated on examples.
