Subtask A addresses the challenge of rumour stance classification,\nwhich involves identifying the attitude of Twitter users towards the\ntruthfulness of the rumour they are discussing. Stance classification is\nconsidered to be an important step towards rumour verification, therefore\nperforming well in this task is expected to be useful in debunking false\nrumours. In this work we classify a set of Twitter posts discussing rumours\ninto either supporting, denying, questioning or commenting on the underlying\nrumours. We propose a LSTM-based sequential model that, through modelling the\nconversational structure of tweets, which achieves an accuracy of 0.784 on the\nRumourEval test set outperforming all other systems in Subtask A.","url_abs":"http://arxiv.org/abs/1704.07221v1","url_pdf":"http://arxiv.org/pdf/1704.07221v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"turing-at-semeval-2017-task-8-sequential","repo_url":"https://github.com/seongjinpark-88/RumorEval2019","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[{"task_slug":"classification","task_name":"General Classification"},{"task_slug":"rumour-detection","task_name":"Rumour Detection"},{"task_slug":"stance-classification","task_name":"Stance Classification"},{"task_slug":"stance-detection","task_name":"Stance Detection"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/stance-detection-on-rumoureval","task":"Stance Detection","dataset":"RumourEval","model":"Kochkina et al. 2017","rank_in_archive_order":1,"of":3,"metrics":{"Accuracy":"0.784"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1704.07221","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
