QuestionAnsweringBERT 0.1

BERT base question answering implementation

QuestionAnsweringBERT

This library is implementation of one of the transfer learning task using BERT model. This is a layer we are writing on top of Hugging Face implementation

Installation

Python version requirement: 3.7 or later

You can install the bleeding edge version of this library by doing:

   git clone https://github.com/swapnanilsharma/QuestionAnsweringBERT.git
   cd QuestionAnsweringBERT
   python3 setup.py install

Or from pip:

   pip3 install QuestionAnsweringBERT

Usage

Using QuestionAnsweringBERT is very easy. Only limitation till now is the paragraph should have less than 512 words/tokens. The model is trained on squad 2.0 which is a general dataset. So it has some limitations for domain specific data. Please check and compare with expected output.

    import QuestionAnsweringBERT as qabert

    paragraph = r"""Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
It was first identified in December 2019 in Wuhan, Hubei, China, and has resulted in an ongoing pandemic. 
As of 5 October 2020, more than 35 million cases have been reported across 188 countries and territories with more than 1.03 million deaths; more than 24.4 million people have recovered.
Common symptoms include fever, cough, fatigue, shortness of breath or breathing difficulties, and loss of smell and taste.
While most people have mild symptoms, some people develop acute respiratory distress syndrome (ARDS) possibly precipitated by cytokine storm, multi-organ failure, septic shock, and blood clots. 
The incubation period may range from one to fourteen days.
The disease spreads most often when people are physically close.
It spreads very easily and sustainably through the air, primarily via small droplets and sometimes in aerosols, as an infected person breathes, coughs, sneezes, talks, or sings.
It may also be transmitted via contaminated surfaces, although this has not been conclusively demonstrated.
It can spread for up to two days prior to symptom onset and from people who are asymptomatic.
The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. 
Chest CT imaging may also be helpful for diagnosis in individuals where there is a high suspicion of infection based on symptoms and risk factors, however guidelines do not recommend using it for routine screening.
Recommended measures to prevent infection include frequent hand washing, social distancing, quarantine, covering coughs and sneezes, and keeping unwashed hands away from the face.
The use of face masks or cloth face coverings such as a scarf or a bandana has been recommended by health officials in public settings to minimise the risk of transmissions, with some authorities requiring their use in certain settings, such as on public transport and in shops. 
Health officials also stated that medical-grade face masks, such as N95 masks, should be used only by healthcare workers, first responders, and those who directly care for infected individuals.
There are no proven vaccines or specific treatments for COVID-19 yet, though several are in development."""
