The representation of semantic structure of  Georgian sentence is considered in the article on the base of its syntactical structure. The base of such experiment is founded on the hypothesis which says, that syntactical and semantic structure of a sentence may be constructed on the base of the principle of compositionally, i.e. complex syntactical and semantic structures may be constructed step by step from initial elementary structures. It means, that a corresponding  semantic  structure exists for a syntactical structure and the final semantic structure may be obtained  by such way and this is considered as the sense of the original sentence. Such approach is founded on the works of R.Montague ([1]),  which was  developed by T.Janssen in his dissertation ([2]). We have in mind, that individual  words of semantic representation is known.

In particular, a common noun is considered as a set of  objects, marked by the noun. The adjectives  are attributes of objects by which an object is adjusted. Some words are considered  as  logical quantifiers.Verbs are actions or situations, which  are marked with the verbs and correspond to  procedures  with a parameters from which some ones are received from the valency of a verb and others carry attributes upward from one level to another. A tree represents the syntactical and semantic structures of a sentence.

The  construction of  syntactical and semantic trees is  illustrated by an example in parallel mode. As the example,  we have considered the context free grammar for a fragment of Georgian  language.  We used  general up-down parsing  algorithm for a context free  grammar ([3]). Corresponding program is composed on  Oz logical programming  language and its work is illustrated for some Georgian sentences ([4]).
