In research writing as a scientific basis in education, some mistakes related to choosing appropriate term or definition take place. This research discusses the solving such problem by using word embedding in the Research Writing discipline. This is a word representation form, where one word has a vector and its coordinates. The words with close meaning have similar direction, showing lexical compatibility. To calculate lexical relations, the cosine of the angle between two words’ vectors are considered. Value of highly compatible word combinations is equal to 1. On the other hand, lexically incompatible words should approximately have value -1.

To test the system the text of the Constitution of the Republic of Kazakhstan was used. Particularly, words which are not related to meaning of article of the Constitution were inserted, and the system had to identify that inserted words. The system for some words showed high accuracy, however some words showed low accuracy. It is suggested that such factor was because even inserted words were not related in meaning, they could be lexically compatible with their neigh bors. This research is carried out within the framework of the Ministry of Education and Science of Republic of Kazakhstan grant project “Developing and implementing the innovative competency-based model of multilingual IT specialist in the course of national education system modernization”.
