This study employs the hybrid keyword extractionmethod proposed by Gries (2021) to analyze diachronic semantic changes of keymaritime terms in International Maritime Organization Assembly Resolutions from 1959to 2023. Traditional frequency-based methods primarily identify high-frequency functionwords, whereas text dispersion-based analysis highlights keywords consistentlydistributed across the corpus, ensuring thematic representativeness. Gries’ (2021) hybridmethod, integrating both frequency and dispersion measures, effectively identifieskeywords that are not only contextually relevant but also semantically significant,providing a more nuanced understanding of specialized discourse. The corpus is dividedinto three distinct periods based on major regulatory and technological milestones,revealing significant semantic shifts in maritime discourse. Keywords such as “safety”and “pollution,” initially having narrow meanings, have notably broadened theirsemantic scope in response to evolving international regulations, technologicaladvancements, and heightened environmental awareness. This study contributes tocorpus linguistics by demonstrating that advanced keyword extraction methods, suchas Gries’ hybrid approach, offer deeper insights into how specialized languages evolvein response to dynamic industry contexts.
