Development of Aircraft Maintenance Glossaries in Higher Education: Exploring Methodological Paths to Corpus-Driven Analysis of Key Keywords

doi:10.12339/j.issn.1673-8578.2025.01.014

Abstract

Abstract:

This paper presents a project aimed at developing a trilingual visual dictionary for aircraft maintenance professionals and students. The project addresses the growing demand for accurate communication and technical terminology in the aviation industry, particularly in Brazil and China. The study employs a corpus-driven approach, analyzing a large corpus of aircraft maintenance manuals to extract key technical terms and their collocates. Using specialized subcorpora and a comparative analysis, this paper demonstrates challenges and solutions into the identification of high-frequency keywords and explores their contextual use in aviation documentation, emphasizing the need for clear and accurate technical communication. By incorporating these findings into a trilingual visual dictionary, the project aims to enhance the understanding and usage of aviation terminology.

Key words: aircraft maintenance, corpus, extraction
