The study examines the relationship between word length and educational stage, as well as the distribution patterns of word-initial letters across stages. A stage-specific vocabulary dataset was constructed, incorporating word lists, frequency data, textbook positioning, word length statistics, and initial-letter distributions. Based on this dataset, correlations were established between word length and educational stage, and between lexical difficulty and progression in schooling. The findings offer data-driven theoretical support for the design of English language teaching and examinations tailored to different educational levels.<\/jats:p>","DOI":"10.3233\/faia251691","type":"book-chapter","created":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T13:19:59Z","timestamp":1769519999000},"source":"Crossref","is-referenced-by-count":0,"title":["Data Analysis of English Vocabulary at Different Educational Stages"],"prefix":"10.3233","author":[{"given":"Junying","family":"Pan","sequence":"first","affiliation":[{"name":"School of Computer Information Engineering, Hanshan Normal University, Chaozhou, China"}]},{"given":"Zhongxing","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Computer Information Engineering, Hanshan Normal University, Chaozhou, China"}]},{"given":"Wei","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Computer Information Engineering, Hanshan Normal University, Chaozhou, China"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Fuzzy Systems and Data Mining XI"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA251691","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T13:19:59Z","timestamp":1769519999000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA251691"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,27]]},"ISBN":["9781643686448"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia251691","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1,27]]}}}
