In general, we will demonstrate that techniques from open-domain QA cannot be directly applied to perform QA on unseen new domains (Tang et al.,2020;Castelli et al.,2020) and emphasize the importance of domain-specic training is necessary. They can extract answer phrases from paragraphs, paraphrase the answer generatively, or choose one option out of a list of given options, and so on. Depending on . This attention is mainly motivated by the long-sought transformation in information retrieval (IR) systems. Question answering is a critical NLP problem and a long-standing artificial intelligence milestone. Question answering provides cloud-based Natural Language Processing (NLP) that allows you to create a natural conversational layer over your data. QA structures permit a person to specific a question in natural language and get a direct and brief reaction. 1948 - In the Year 1948, the first recognisable NLP application was introduced in Birkbeck College, London.. 1950s - In the Year 1950s, there was a conflicting view between linguistics and computer science. Each question-answer entry has: a question; a globally unique id; a boolean flag "is_impossible" which shows if the question is answerable or not; in case the question is answerable one answer entry, which contains the text span and its starting character index in the context. You can use Question Answering (QA) models to automate the response to frequently asked questions by using a knowledge base (documents) as context. What is Question Answering. The core content covers RNN, LSTM, CNN, transformer, bert, question answering, abstract, text generation, language model, reading comprehension and other cutting-edge content. This module identifies the context and focus, classifies the type of question, and sets the answer type's expectations. a survey on question answering datasets with a particular focus on the required reasoning skills (Rogers et al., 2021); a survey on neural unsupervised domain adaptation in NLP (Ramponi & Plank, 2020); the ACL 2020 tutorial on open-domain question answering; and my ACL 2019 tutorial on cross-lingual representation learning.
