We fine-tune the BERT, RoBERTa, ALBERT, XLNet and ELECTRA transformers and their connecting classifiers. Each transformer model is regarded as a standalone method to detect tweets that self-reported chronic stress. The final output classification result is then combined using the majority voting ensemble mechanism. Experimental results indicate that our approach achieved a best F1-score of 0.73 over the positive class.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"393\" src=\"http:\/\/140.115.70.194:6417\/wp-content\/uploads\/2023\/12\/\u622a\u5716-2023-12-29-\u4e0b\u534811.32.13-1024x393.png\" alt=\"\" class=\"wp-image-496\" srcset=\"https:\/\/ainlp.tw\/wp-content\/uploads\/2023\/12\/\u622a\u5716-2023-12-29-\u4e0b\u534811.32.13-1024x393.png 1024w, https:\/\/ainlp.tw\/wp-content\/uploads\/2023\/12\/\u622a\u5716-2023-12-29-\u4e0b\u534811.32.13-300x115.png 300w, https:\/\/ainlp.tw\/wp-content\/uploads\/2023\/12\/\u622a\u5716-2023-12-29-\u4e0b\u534811.32.13-768x294.png 768w, https:\/\/ainlp.tw\/wp-content\/uploads\/2023\/12\/\u622a\u5716-2023-12-29-\u4e0b\u534811.32.13.png 1346w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Tzu-Mi Lin, Chao-Yi Chen, Yu-Wen Tzeng and Lung-Hao Lee<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_themeisle_gutenberg_block_has_review":false,"footnotes":""},"categories":[6],"tags":[35,43,21],"class_list":["post-494","post","type-post","status-publish","format-standard","hentry","category-achievements","tag-35","tag-emotion","tag-smm4h"],"blocksy_meta":[],"_links":{"self":[{"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/posts\/494","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/comments?post=494"}],"version-history":[{"count":2,"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/posts\/494\/revisions"}],"predecessor-version":[{"id":792,"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/posts\/494\/revisions\/792"}],"wp:attachment":[{"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/media?parent=494"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/categories?post=494"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ainlp.tw\/index.php\/wp-json\/wp\/v2\/tags?post=494"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
