Welcome to submit to 2nd DialDoc and Shared Task co-located with ACL 2022! ** About ** The Second DialDoc Workshop, co-located with ACL 2022, focuses on document-grounded dialogue and conversational question answering. There is vast amount of document content created every day by human writers to communicate with human readers for sharing knowledge, ranging from encyclopedia to social benefits. Making the document content accessible to users via conversational systems and scaling it to various domains could be a meaningful yet challenging task. There are significant individual research threads that show promise in handling heterogenous knowledge embedded in documents for building conversational systems, including (1) unstructured content, such as text passages; (2) semi-structured content, such as tables or lists; (3) multi-modal content, such as images and videos along with text descriptions, and so on. The purpose of this workshop is to invite researchers and practitioners to bring their individual perspectives about document-grounded dialogue and conversational question answering to advance the field in a joint effort. We welcome submissions of original work as long or short papers, as well as non-archival papers. All accepted papers will be presented at the workshop. We will have the Best Paper Award and Best Student Paper Award, which will be announced during the workshop. Topics of interests include but not limited to - document-grounded dialogue and conversational machine reading; - open domain dialogue and conversational QA; - conversational search among domain documents; - parsing semi-structured document content for dialogue and conversational QA, table reading; - summarization for dialogue, query-based summarization; - evaluations for document-grounded dialogue; - interpretability and faithfulness in dialogue modeling; - knowledge-grounded multimodal dialogue and question answering. ** Important Dates ** Feb. 28, 2022: Workshop Paper Due Date March 26, 2022: Notification of Acceptance April 3, 202: Final submission to Shared Task Leaderboard April 10, 2022: Camera-ready papers due May 26-28, 2022: Workshop Dates ** Workshop Website ** http://doc2dial.github.io/workshop2022/ Amazon Spain Services sociedad limitada unipersonal, Calle Ramirez de Prado 5, 28045 Madrid.
