Journal Title: Закарпатські філологічні студії - Year 2018, Vol 6, Issue
Abstract
The article considers the description of the step sequence in forming the text corpora, and then frequency dictionaries on the example of Acoustics and Ultrasonic Technique (AUST) specialty, the texts of which are referred to scientific and technical discourse. The necessity of application of real text corpora compiled with the help of statistical methods in the present-day research processes is proved. Statistical method usage allows to determine such a mandatory parameter as the reliability of text corpus and lexicographic resources created on its basis – frequency dictionaries, alphabet-frequency dictionaries, etc. The example of specialty AUST demonstrates how statistically verified characteristics of the text corpus allowed to create a reliable probabilistic-statistical model (frequency dictionary) of this subject area. The statistical reliabil- ity of the dictionary manifested itself in the fact that the percentage of covering the AUST texts with the units of the base dictionary (the first 2 thousand words) is 86%, which makes it possible to understand the content of almost any text on the specialty AUST using the lexical units presented in it (the base dictionary).
