      <title>1. Introduction</title>
      <p>
        Recently, an outbreak caused by the virus
named SARS-CoV-2 has impacted the lives of
humans very badly across the globe. The very
first occurrence of COVID-19 was enlisted in
December 2019 in China. The infection may
outspread from bats to people through another
median host and cause extreme respiratory
disorder, described by strong man-to-man
transferal through the air [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ]. From that
particular day, there’s a rapid growth
number of cases being registered daily. And the
many countries were under lockdown for almost
3-4 months. During this period, people face
many problems financially, medically. This
global pandemic has even made a negative
impact on the economy of most of the countries.
      </p>
      <p>This global pandemic has made a
devastating impact on several domains like
education, business, and others. There are
many problems that people are facing in this
situation. The medical staff is facing problems
in providing medical assistance to the people
in need, providing awareness among the
people has become difficult, many people need
financial help and the list goes on. We need to
solve the COVID-19 crisis and help people
using technology.</p>
      <p>As a collective solution to all the problems,
we are proposing a user-friendly, reliable web
application that includes a COVID-19 tracker,
COVID-19 prediction, a Chatbot, and many
other features which are solutions to some
problems faced by people. We are trying to
integrate an efficiently developed Chatbot,
which can assist people to surf the website and
thealso accurately answer the COVID-19 related
queries they have.</p>
      <p>On the internet, there are many applications,
websites that are designed and developed to
predict the COVID-19 outbreak. The models
used various machine learning algorithms, deep
learning algorithms and a few have used some
statistical methods to do predictions. All these
models provide acceptable accuracy but the
development of the model is complex in nature.
To eliminate the hassle included in the
development of the model, we tried to design a
simple mathematical algorithm, called Generic
hypothesis algorithm to make the predictions
without compromising on the accuracy of
predictions.</p>
      <p>This paper aims to design and develop a
reliable and easy to use the web application
through which help can be offered to the people
in need. The flow of development starts with the
requirement analysis, finalizing the design of the
application followed by the Chatbot, COVID-19
prediction model development, and then
integrating all the developed components.</p>

      <title>2. Related Work</title>
      <p>
        In a pandemic like this, providing timely
information to the public is very important. So,
the authors thought of developing a
COVID19 tracker. A stage like Corona Tracker will
help the public authority &amp; specialists to
spread checked articles, give updates to the
circumstance, &amp; backer great individual
cleanliness to the individuals. They used the
data from the John Hopkins University (JHU)
which is a trusted source [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. They used
Susceptible-Exposed-Infected Removed
(SEIR) model to do the predictions of
COVID19 outspread.
      </p>
      <p>
        In [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], authors propose a system which
screens individuals for disease. They used
artificial intelligence (AI), digital artificial
intelligence (AI), digital thermometers, mobile
phone applications, thermal cameras,
webbased toolkits for developing this system. This
system gives data on infection pervasiveness
&amp; pathology, recognizes people for testing,
contact following, &amp; confinement. It neglects
to identify asymptomatic people whenever
dependent on self-detailed side effects or
observing of fundamental signs, includes
significant expenses &amp; requires validation of
screening tools.
      </p>
      <p>
        [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ] proposes a system that helps in tracking
the people who might get infected with
COVID19. The developed can identify and track people
who may have come into contact with the tainted
individual utilizing worldwide situating
frameworks, constant checking of cell phones,
and wearable intelligent gadgets. As the system
identifies the people who got in contact with the
infected person, we can contact them, and ask
them to take tests, isolate them to stop the viral
spread to some extent. There are few
disadvantages to the system like it can’t track the
exposed people when the device is offline, there
is a scope for cloud breach.
      </p>
      <p>
        In [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ], the authors proposed forecasting
models with logistic and prophet model to
predict COVID-19. The data is collected from
JHU, which released a dashboard at the country
level. Data is first fed into the logistic model
and then cap value is given to the prophet
model for forecasting. This paper concludes
that a hybrid logistic and prophet model has
been good in predicting the epidemic trend and
it is also capable of predicting the number of
infections that might occur across the globe or
in particular country.

      <p>
        [
        <xref ref-type="bibr" rid="ref5">5</xref>

track infected people and implement
quarantine. To develop this system,
technologies like artificial intelligence, digital
recorders, quick response codes, and mobile
applications are used. It helps in stopping the
communal spread of disease. It fails to track
infected people who don’t carry their devices
and the system also violates civil liberties.

      <p>
        [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ] proposes a model that diagnoses
infected people, monitors clinical status and
also predicts the required capacity to provide
telemedicine, virtual care services. This can be
achieved by using artificial intelligence (AI)
and machine learning (ML) techniques can be
used for providing telemedicine, virtual care
services. Sometimes the system may fail in
diagnosis of disease and development of
system involves high costs.
      </p>
      <p>
        [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] proposes a telemedicine service which
can be accessed and used by the people in all
locations. Using services like this can reduce the
number of people coming out of homes and that
directly impacts the outbreak of
COVID19. For the disease diagnosis, virtual checkups
and care authors used AI. System helps to
transport the medicine to the particular patient
at immediate from online booking but the
transportation time may be large for some
remote areas, which makes the patients into
danger.
      </p>
      <p>
        [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] proposes a model for anticipating
COVID-19 threatening movement with AI
methods. The proposed model can be viably
utilized for discovering the mellow patients
who are anything but difficult to weaken into
extreme/basic cases, so such patients get
convenient therapies while reducing the
restrictions of clinical assets. There’s a scope
for wrong predictions and this leads to the
wastage of medical facilities.
      </p>
      <p>
        Chatbots may be highly useful in pandemic
situations like this because people want to know
where, how and at what rate the infection is
spreading. But information dissemination,
symptom monitoring, providing mental health
support are challenging tasks in the
development of these chatbots [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. If the
chatbots are designed and developed in an
efficient way they can solve the problem of
misinformation, which is one of the major
problems in the pandemic situation.

      <p>
        In [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ], authors proposed a forecasting
model which can predict number of
confirmations, recoveries and deaths registered
because of COVID-19. Prediction models such
as the PA, ARIMA, and LSTM algorithms
were used to predict the number of COVID-19
confirmations, recoveries, &amp; deaths over the
next 7 days and acquired prediction accuracies
of 99.94%, 90.29%, and 94.18%, respectively.
Under this paper they also propose a diagnosis
model using VGG-16 to detect COVID-19
utilizing chest X-ray images. The model
allows the rapid &amp; reliable detection of
COVID-19, enabling it to achieve an
Fmeasure of 99% using an augmented dataset.

      <p>
        [
        <xref ref-type="bibr" rid="ref11">11</xref>

limiting the COVID-19 transmission, increase
health care providers capability and capacity;
prevent/predict the future outbreaks. For this
system they used telemedicine, tele-critical care,
tiered tele-mentoring. This system makes sure
that the patient gets convenient healthcare from
the comfort of their own home. This might be
good for treating patients with small diseases like
flu or general fever but are not efficient to treat
people with some serious health issues.
      </p>
      <p>
        Lately, social media is considered as one
platform to share information to have maximum
reach. To make use of this fact the authors have
come up with an idea of bringing awareness and
social control in the public using social media
[
        <xref ref-type="bibr" rid="ref12">12</xref>
        ]. They used smart phone thermometers
instead of the regular apparatus and they also
used cough type detection using an extensive set
of acoustic features applied to the recorded
audio. This might not require huge investments
but requires a lot of time to do all the campaigns
and show visible results.
      </p>
      <p>
        The authors [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ] propose a system that
cando disease diagnosis using the radiology
images. AI &amp; deep learning are some of the
techniques that they preferred to use in
building this system. This system helps in
decreasing the exposure of patient to radiation
and it requires no preparation but it is more
expensive compared to the radiography and
provides basic anatomic information for only a
few tissue densities.
      </p>
      <p>
        As mobile partnership has widely increased
in the recent years, the authors came up with the
idea of developing mobile applications to track
their health. To do this they proposed usage of
GRU neural network, SEIR model and other
techniques [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ]. The cost of development is
high and it’s a challenge to collect
prospective data from social media.

      <p>
        [
        <xref ref-type="bibr" rid="ref15">15</xref>
        ] proposes a system that predicts the
patient’s health condition using XGBoost
classifier, machine learning based CT
radiomics models. The predictions are made
based on the patient health records submitted.
Having access to the health records helps in
studying the case properly and treat them in
the best way possible. Besides the advantages
this model also has its disadvantages as the
system requires large amount of private data.

      <p>
        In [

Linear regression &amp; Vector autoregression
approaches on a publicly available COVID-19
Kaggle dataset for COVID-19 cases in India.

affected places in India and Tamil Nadu, then
to provide COVID-19 tracker to find state case

      <title>3.3Methodology</title>
      <p>We approached solution for the pandemic
situation using web application development
with 3 major functionalities like NLP Chatbot
Integration, automating our 3D printer and
sending live print stream using Raspberry Pi 3,
forecast predicting the cases using exponential
function and forum for more.</p>
      <sec id="sec-6-1">
        <title>NLP Chatbot Integration</title>
        <p>We built Chatbot using Dialog flow console
works with the help of google cloud. This NLP
chatbot is a fully automatic chatbot where input
gets invoked and response trained are processed
and sent by google cloud. The invoking phrases
are trained, then the trained inputs processing
can be manipulated using fulfillment coding
using node.js program and the response for the
input phrases are also trained accordingly.</p>
        <p>The Chatbot in this application helps in
getting,
❖ Government Helpline numbers
❖ Remote Education
o Learn A – Z (which for</p>
        <p>children under age of 6)
o Learn Tables (for above</p>
        <p>age of 7)
❖ Hotspot Locations and COVID-19</p>
        <p>Tracker</p>
        <p>India’s statse and union territories helpline
numbers are trained, then by invoking state or
union territory name we will get their state’s
helpline number as a response.</p>
        <p>Remote education is machine learning
based where the data are trained and used
according to the node.js program we coded.</p>
        <p>The Hotspot locations we get from the
developed chatbot was developed by node-red
console in that using world map node, we
marked the Top 10 affected locations using
their latitude and longitude coordinates by
getting dynamic API which was developed by
reusing the JHU’s API.</p>
        <p>The COVID-19 tracker is developed with
the help of JHU API.</p>
        <p>The Chatbot is integrated in web
application as a widget by using Botcopy to
make the widget as a script which connects
with the google cloud directly to invoke the
input phrases.</p>

        <title>3D Printer automation using IoT</title>
        <p>We used Raspberry Pi 3 to automate our 3D
printer using octopi application and configured
our 3D printer with that application. Then
connecting Raspy Cam with Pi then enabling
camera features in terminal. Later when we
receive order from the web application, we will
be sending the live stream URL of 3D printing
of their own order through mail and also in
SMS. The streaming is prepared by coding the
spaghetti detective plugin connection in
Raspberry Pi, so that the customers can watch
their mask printing lively and give feedback to
us.</p>

        <title>Forecast Prediction of cases</title>
        <p>The forecast prediction of COVID-19 cases
is prepared by using general exponential
function. We used this mathematical function
because the cases in America is increased
exponentially, so rather for every country it
applies. So, after getting 10 days of case
details we will be dividing every 2 days total
cases (2 points in a graph) the resultant will be
its growth factor. For that 10 days we will be
getting 5 growth factors and taking mean for
that growth factors. Then using the
exponential function Y = abx</p>
        <p>where a is the current total cases, b is the
mean of growth factor and x is the number of
predication days we want to predict. By using
this general exponential function, we got
around 89 to 92% of accuracy in prediction.</p>

This project helps the user in getting most of
the information’s majorly needed during this
pandemic situation. The proposed systems are
mostly a single major feature application, but
we combined everything together and made it
work it as a light weight application. This is
also has been developed in android for
converting into a app.</p>
      <p>In future we can make chatbot more
accurate and efficient, the geofencing concept
can also be added. Then in Android still more
upgradations can be done. The deep learning
