Open-domain question answering (QA), which fulfills a user’s information need by outputting di- rect answers to natural language queries, is a chal-lenging but important problem (Etzioni, 2011). making the subject answering a multiple choice question of which the category the image belongs to is shown using a mouse. {84} H. Yang, T. Chua, S. Wang, and C. Koh, "Structured use of external knowledge for event-based open domain question answering," in Proceedings of the 26th Annual International ACM SIGIR Conference on Research and Development in Information Retrieval, pp. Wei-Cheng Chang et.al. Question answering systems in the context of machine reading applications have also been constructed in the medical domain, for instance related to Alzheimer's disease.

Full Text. 13:30–13:48 We argue that both are suboptimal, since gold evidence is not always available, and QA is fundamentally different from IR. How can I correct errors in dblp? Recently, the state- of-the-art machine reading models achieve hu- man level performance in SQuAD which is a reading comprehension-style question an- swering (QA) task. .. Real-Time Open-Domain Question Answering with Dense-Sparse Phrase Index 2. Distantly supervised open-domain question answering (DS-QA) aims to find answers in collections of unlabeled text. Recent breakthroughs of pretrained language models have shown the effectiveness of self-supervised learning for a wide range of natural language processing (NLP) tasks. Recent work on open domain question answering (QA) assumes strong supervision of the supporting evidence and/or assumes a blackbox information retrieval (IR) system to retrieve evidence candidates. We introduce readers to the … 1 datasets • 48119 papers with code. 3 Medical Domain sub-task In addition to the main question answering task, a subtask for medical question answering is in-troduced this year.

Oral presentations. We argue that both are suboptimal, since gold evidence is not always available, and QA is fundamentally different from IR. domain adaptation or domain adaptation methods that presume a single underlying domain shift. Latent retrieval for weakly supervised open domain question answering. Existing DS-QA models usually retrieve related paragraphs from a large-scale corpus and apply reading comprehension technique to extract answers from the most relevant paragraph. 11 1 0 1 0 Reading Wikipedia to Answer Open-Domain Questions 2. Automated question answering - the ability of a machine to answer questions, simple or complex, posed in ordinary human language - is one of today’s most exciting technological developments. retrieval (or “pull”) operations on the corpus and/or KB.

Many question answering (QA) tasks only provide weak supervision for how the answer should be computed. Abstract Recent work on open domain question answering (QA) assumes strong supervision of the supporting evidence and/or assumes a blackbox information retrieval (IR) system to retrieve evidence candidates.

Information retrieval. We would like to express our heartfelt thanks to the many users who have sent us their remarks and constructive critizisms via our survey during the past weeks. 1 Introduction Open-domain question answering (QA) is an im- portant means for us to make use of knowledge in large text corpora and enables diverse queries without requiring a knowledge schema ahead of time. applied to the task of open domain QA. Instead of using opaque and com- putationally expensive neural retrieval models, GOLDENRetriever generates natural language search queries given the question and available context, and leverages off-the-shelf informa- tion retrieval systems to query for missing en- tities. Question generation in large-scale, open-domain dialogue systems is relatively unexplored. 2 YUAN ET AL. The task of information retrieval is an important component of many natural lan-guage processing systems, such as open domain question answering. Latent Retrieval for Weakly Supervised Open Domain Question Answering. 2016), Wikipedia contains up-to-date knowledge that humans are interested in. We call F a fake-representation generator.
