The basis of any intellectual resource is a knowledge base, which, based on the basic terms of the field under consideration, builds relationships between them. Therefore, the first task to building multilingual information system using Natural language processing (NLP)in scientific and educational activities will be the development of a multilingual dictionary on modern NLP methods, including terms in Kazakh, English and Russian. For its construction, linguistic models for semantic dictionaries and thesauruses will be used, as well as methods of automatic extraction of terms from the corpus of texts of a given subject area. In this paper, a system of concepts of the NLP domain will be formalized, which will form the terminological core of the NLP ontology. To systematize information and provide support for multilingualism and accessibility, we plan to apply ontological engineering methods to systematize information and build the upper levels of the NLP ontology (its terminological core) using the dictionary of terms obtained at the previous stage. The ontology developed by us can later become the conceptual basis for a multilingual information system used in scientific and educational activities using NLP. This system will provide systematization of all information, convenient navigation on it, integration into a single information space, as well as access to it.
