Researchers built an 8.65-million-word Language Education Research Corpus from ten Q1 journals and derived a word list covering 5.28% of the source corpus and 4.75% of an independent corpus.
Key findings
- LERWL covered 5.28% of LERC and 4.75% of the independent same-field corpus, showing coverage beyond the development set.
Why this matters globally
A field-specific list may prioritize vocabulary for ESP learners and researchers after general and academic foundations.
Thai researcher contribution
A Thammasat University researcher developed a lexical resource from international literature with a reproducible selection framework.
Limitations to consider
Ten top journals may bias publisher, language and topic representation. Token/family definitions and expert details are absent from the abstract, and coverage is not pedagogical effectiveness.
