Kasetsart University researchers compiled 10,901 Scopus-indexed airline-business abstracts from 2015–2024, totaling 2.08 million tokens. Corpus analysis and researcher judgement organized trends into topics, research intentions, concepts, participants and methods.
Key findings
- Annual keyword patterns across the five themes reveal dominant interests and less prominent areas that researchers may either follow or deliberately explore.
Why this matters globally
Airlines connect trade and tourism globally. The map can inform research agendas amid digital, climate and passenger-behavior change.
Thai researcher contribution
Five Kasetsart University authors developed the ABRAC corpus and an integrated computational-and-judgement workflow.
Limitations to consider
Scopus-only abstracts omit other databases, books, industry reports and full-result detail. Human classification is interpretive, and word frequency is not policy importance.
