In addition, it introduces two effective ways to construct unanswerable questions, namely, negative question sampling and context truncation, which enable the model to handle “none” value slots in the zero-shot DST setting.","description_state":"present","introduced_year":null,"introduced_by":{"title":"Zero-Shot Dialogue State Tracking via Cross-Task Transfer","paper":"/paper/zero-shot-dialogue-state-tracking-via-cross","first_author":"Zhaojiang Lin","n_authors":11,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/zero-shot-dialogue-state-tracking-via-cross"},"source":{"url":"https://arxiv.org/abs/2109.04655v1","title":"Zero-Shot Dialogue State Tracking via Cross-Task Transfer","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Natural Language Processing","area_id":"natural-language-processing","collection":"Question Answering Models","url":"/methods/category/question-answering-models","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/zero-shot-dialogue-state-tracking-via-cross","title":"Zero-Shot Dialogue State Tracking via Cross-Task Transfer","date":"2021-09-10","arxiv_id":"2109.04655","n_code_links":1,"syntology":null}],"papers_shown":1,"tasks":[{"task":"/task/dialogue-state-tracking","name":"Dialogue State Tracking","papers":1},{"task":"/task/question-answering","name":"Question Answering","papers":1},{"task":"/task/transfer-learning","name":"Transfer Learning","papers":1}],"tasks_shown":3,"n_tasks":3,"usage_by_year":[{"year":"2021","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/transferqa"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
