In the article the essential characteristics of the role relations of “sentential primitives” and specifically primitives, containing the adjectives of the Georgian language and a model for their automatic translation into English are considered. According to the fact which member of the sentence the adjective is connected with and what role it plays in the sentence, types of sentential primitives are separated. If during the translation process both languages are provided with means of partitioning into primitives and vice versa, compiling an expression from primitives, then the process will be brought up to the level of translation of primitives, and the translation will be significantly simplified. 

Fundamental scientific researches in Computational Linguistics have been carried out at the Archil Eliashvili Institute of Control Systems, Georgian Technical University, for many years. Various combination methods (lexical functions, synonymous series, semantic roles and superparadigms) were developed for the Georgian language; A computer dictionary of the Georgian language has been created, which, at the same time, carries out functions of a morphological generator, in other words, it produces the full paradigm for each lexical unit. Within the framework of the fundamental issues of language modeling, a means of presenting linguistic algorithms has been developed, that allows the formulation of a bi-directional analysis-combined processor. For some languages, the filling-widening process of dictionaries ​​has been simplified with the help of a grammar compiler, which is the most modern tool for the automatic realization of a formal language model. It is possible to compile morphological processor libraries of individual languages ​​for different variations of any language (according to time, space, origin, genre, etc.) and so on. Automatic machine translation can be considered as the main achievement. To solve this task completely it is necessary to create lexical translator. This type of system is rather valued among the ordinary users, as it makes it easier for them to learn foreign-language texts intensively thus is much more useful while composing text. The strategy of our team is to provide reliable support for future language technologies by the theoretical and practical key issues that have been worked up in separate projects for the past years. The computer products created by our team are used in various linguistic areas. It is a challenge for linguists to create computational model of a language, taking into account its multi detections and changes. We have created main components to compile a national corpus manager.

Language modeling is one of the most important directions in modern linguistics. Linguistic models are characterized, on the one hand, by the division of the linguistic system into several levels (morphological, syntactic, semantic), and, on the other hand, by the establishment of direct connections between these levels. It is possible to rely on the "explanatory-combinatorial dictionary" for the agreed functioning and effective operation of different levels of the Georgian language model. In the computer explanatory-combinatorial dictionary of the Georgian language, all the information around the lexeme is divided into zones: first - the word commander, second - the definition of the word, third - the morphological model, fourth - the semantic-syntactic model of the word; the fifth zone is devoted to the list of lexical functions of speech. With the support of Shota Rustaveli National Science Foundation, a generator of the Georgian Explanatory-Combinatorial Dictionary was developed. To create it, we use the modern approach to the syntax and semantics of the Georgian language: "layered" syntactic structures; I. Melchuk - Theory of lexical parameters; J. Apresian - method of synonymous sequences. From the point of view of Kartvelology, this is an extension, strengthening and updating of the Georgian language description methodology in accordance with the new international standards; for the above modern theories - a new test of their cross-linguistic suitability; In terms of computer linguistics, this work provides a strong basis for creating a complete functional model of the Georgian language.

The article discusses the peculiarities of declination of some georgian language nouns in plural. Linguistic events are subject to certain regularities, but besides the general rules there are exceptions. The focus is on the forming issues of some noun plural forms. According to the already established rule, the nouns of a certain group do not use plural forms. They are called uncountable nouns. Such are the nouns of substances, abstract, collective, but it is not uncommon to use such nouns in the plural during different semantic loads. Some adjectives are turned into nouns in plural forms (reds, greens, rich, poor, etc.). In the article for ilustration a lot of word combination – collocation are presented which have already been well-established in the Georgian language, such as „ქართული ღვინოები“ - Georgian wines, „მარილების დაგროვება“- salt accumulation, „მინარალური წყლები“-mineral waters - (nouns of substances); "ფიქრები”-Thoughts, „მოტივები“-Motives, „არჩევნები“-Elections - (abstract nouns); „გუნდები“-Teams, „კრებები“-Congregations - (collective nouns): and others.

Georgian computer prompter is a software which can assist the disabled to write in Georgian on the computer. As is known this problem cannot yet be solved by any current software. This system suggests the correct forms of the word and makes it easy to use the keyboard with the minimum of effort.The development of the Georgian morphological processor is provided by means of knowledge collection MESLM Multilanguage expert system. MESLM can be regarded as an instrument which imitates the human mind and creates morphological rules for any language processor. Development of the Georgian language processor by means of the MESLM system software includes three components. These are: verb, noun and other parts of speech. By this time the Georgian text corpora has been filled with about one million words. The software will assist the users to select grammatically correct words while keying in Georgian texts by means of specifying the sequence of words.

The computer based language research serves as means for creation of theoretical-conceptual and algorithmic-applied basis of the language. We think that our models satisfy these requirements. We have fundamentally elaborated morphologic synthesis and analysis for Georgian language, which include the quite exhaustive stem dictionary. The essential problem of semantics syntax and lexicology are also investigated. It’s worthwhile to consider some general or concrete questions, for example, such as: some suppositions about two kinds of the synonymy - arbitrary (on the syntactic level) and restricted one (on the morphologic level); we think that arbitrary synonymic is a source of language enrichment (the examples of this are paraphrases, style, poetry, ..., and some other characteristics which confirm the flexibility of language); moreover we think that homonymy performs a positive function, particularly, the language economically uses its building materials. The morphologic synthesis of Georgian word forms is computerized together with its stem dictionary.
