March 10, 2021. One of the ways to assess reading comprehension is to pose questions based on a given text. This pre-trained model can be fine-tuned and used for different tasks such as sentimental analysis, question answering system, sentence classification and others. What if we can do it in a few lines of code using BERT. The current BERT-based question answering systems use a question and a contextual text to find the answer. The Open Model Zoo repository now comes with a BERT Question Answering Python Demo to input passages (i.e., from the URL) and questions, and to get responses generated by the BERT model in return. In Question Answering tasks, the model receives a question regarding text content and is required to mark the beginning and end of the answer in the text. Here I will be focusing on context-based question answering, where questions are asked from a given paragraph. The text contains the context that is used by Longformer for answering the question. The broken up context would overlap over 128 tokens (specified by the doc_stride)- to make sure a Question has access to the sentences in the Context that come before and after an Answer text.

BERT, which stands for Bidirectional Encoder Representations from Transformers, is a major breakthrough in NLP in 2018. BERT Question-Answering. SpanBERT was developed as an improvement on the BERT model to predict the Spans of the text. One of the most popular datasets for training is SQuAD (Stanford Question Answering Dataset), a dataset developed at Stanford University. QG for improving question answering. The Data: meet the SQuAD. I’m Patrick Xia. Which *BERT? Stanford Question Answering Dataset (SQuAD) is a reading comprehension dataset, consisting of questions posed by crowdworkers on a set of Wikipedia articles, where the answer to every question is a segment of text, or span, from the corresponding reading passage, or the question might be unanswerable. Traditional question answering datasets, such as MCTest, have been high in quality. Text summarization is the process of shortening a long piece of text with its meaning and effect intact. In tasks like sentence pair, single sentence classification, single sentence tagging, and question answering, the BERT framework is highly usable and works with impressive accuracy. As you can imagine, it’s the text that we specified above. To fine-tune BERT for a Question-Answering system, it introduces a start vector and an end vector. a question and then extracts a text span from the document as an answer.
