Tasks and duties

The main mission of the center is to conduct theoretical and applied researches on the development of the Arabic language and linguistics; in cooperation with the bodies and institutions concerned with the unification and approval of terminology, the implementation of research projects in the fields of sciences of language and its techniques applied to the Arabic language and broad-based languages, in order to develop the Arabic language at the educational and technological level.

Research areas

In this context, the Center also carries out research in:

Arab linguistics

This is by focusing on the theory called neo-khalilien theory, trying to deep in and develop it to make a comparison with other linguistic theories.

The science of linguistics and the teaching of Arabic at all levels of education

By conducting critical scientific studies for the teaching of Arabic and foreign languages ​​in Algeria, organizing comparative experimental educational seminars, and controlling the methods of linguistic education.

Arabic dictionaries and terminology

To contribute and to control Arab scientific and technical terms at the level of the Arab world.

The art and science of translation

By conducting scientific studies in translation methods and controlling translation techniques that respond to the needs of translators of scientific books.

Automated treatment of computational language or linguistics

With the contribution of research conducted to formulate linguistic theories, especially modern Hebronic theory, theoretical formulation. As well as a critical study of scientific theories in this field, and the setting of software and other computer tools to invest in the teaching of languages, lexicology, speech diseases, data bases, and so on.
