+.. Automated Essay Grader documentation master file, created by
+   sphinx-quickstart on Wed Nov 27 01:05:04 2019.
+   You can adapt this file completely to your liking, but it should at least
+   contain the root `toctree` directive.
+
+Welcome to Automated Essay Grader's documentation!
+==================================================
+
+Automated Essay Grader is essentially a usable wrapper for using machine learning models based on Essay grading. Our project runs on ``Starlette server`` hosted on ``Heroku cloud`` with a noSQL database hosted on ``Firebase``. Using ``MVC architecture`` we have created a web interface powered by ``Bootstrap 4.0``. Our project also has a fully featured ``Android`` interface.
+
+To check a live web demo `Check out <https://codigos.herokuapp.com/>`_
+
+
+Project environment setup
++++++++++++++++++++++++++
+
+To start the project you first need to install all dependencies:
+
+    >>> pip install requirements.txt
+
+After we have all the requirements set up, we will now create an environment
+
+    >>> conda env create -f Softlab.yml
+
+After the environment is set up you can initialize the environment somehow
+
+    >>> conda activate Softlab
+
+Yes that was it!! Now simply start the system by typing 
+
+    >>> python3 main.py
+
+
+Deployment steps using Docker
++++++++++++++++++++++++++++++
+
+1) You can simply build the the image file by running following in the directory where Dockerfile is present
+
+    >>> docker build --tag essay-grader .
+
+    >>> docker run --name essay-grader -p 8000:8000 essay-grader
+
+
+Checkout some code now

+;; style file for xindy
+;; filename: LICRlatin2utf8.xdy
+;; description: style file for xindy which maps back LaTeX Internal
+;;   Character Representation of letters (as arising in .idx index
+;;   file) to UTF-8 encoding for correct sorting by xindy.
+;; usage: for use with the pdflatex engine,
+;;        *not* for use with xelatex or lualatex.
+;;
+;; This is based upon xindy's distributed file tex/inputenc/utf8.xdy.
+;; The modifications include:
+;;
+;; - Updates for compatibility with current LaTeX macro encoding.
+;;
+;; - Systematic usage of the \IeC {...} mark-up, because mark-up in
+;;   tex/inputenc/utf8.xdy was using it on seemingly random basis, and
+;;   Sphinx coercing of xindy usability for both Latin and Cyrillic scripts
+;;   with pdflatex requires its systematic presence here.
+;;
+;; - Support for some extra letters: Ÿ, Ŋ, ŋ, Œ, œ, IJ, ij, ȷ and ẞ.
+;;
+;;   Indeed Sphinx needs to support for pdflatex engine all Unicode letters
+;;   available in TeX T1 font encoding.  The above letters are found in
+;;   that encoding but not in the Latin1, 2, 3 charsets which are those
+;;   covered by original tex/inputenc/utf8.xdy.
+;;
+;; - There is a problem that ȷ is not supported out-of-the box by LaTeX
+;;   with inputenc, one must add explicitely
+;;       \DeclareUnicodeCharacter{0237}{\j}
+;;   to preamble of LaTeX document.  However this character is not supported
+;;   by the TeX "times" font used by default by Sphinx for pdflatex engine.
+;;
+;;     **Update**: since LaTeX 2018/12/01, the \j as well as \SS, \k{} and
+;;                  \.{} need no extra user declaration anymore.
+;;
+;; - ẞ needs \DeclareUnicodeCharacter{1E9E}{\SS} (but ß needs no extra set-up).
+;;
+;; - U+02DB (˛) and U+02D9 (˙) are also not supported by inputenc
+;;   out of the box and require
+;;       \DeclareUnicodeCharacter{02DB}{\k{}}
+;;       \DeclareUnicodeCharacter{02D9}{\.{}}
+;;   to be added to preamble.
+;;
+;; - U+0127 ħ and U+0126 Ħ are absent from TeX T1+TS1 font encodings.
+;;
+;; - Characters Ŋ and ŋ are not supported by TeX font "times" used by
+;;   default by Sphinx for pdflatex engine but they are supported by
+;;   some TeX fonts, in particular by the default LaTeX font for T1
+;;   encoding.
+;;
+;; - " and ~ must be escaped as ~" and resp. ~~ in xindy merge rules.
+;;
+;; Contributed by the Sphinx team, July 2018.
+;;
+;; See sphinx.xdy for superior figures, as they are escaped by LaTeX writer.

+;;
+;; The aim for Sphinx is to be able to index in a Cyrillic document

+;; with diacritics.  To this effect the xindy rules from lang/general
+;; got manually re-coded to avoid collisions with the encoding

+;; observed not to use bytes with octal encoding 0o266 or higher.
+;;
+;; So here we use only 0o266 or higher bytes.

+Automated Essay Grader is essentially a usable wrapper for using machine learning models based on Essay grading. Our project runs on \sphinxcode{\sphinxupquote{Starlette server}} hosted on \sphinxcode{\sphinxupquote{Heroku cloud}} with a noSQL database hosted on \sphinxcode{\sphinxupquote{Firebase}}. Using \sphinxcode{\sphinxupquote{MVC architecture}} we have created a web interface powered by \sphinxcode{\sphinxupquote{Bootstrap 4.0}}. Our project also has a fully featured \sphinxcode{\sphinxupquote{Android}} interface.

+\chapter{Project environment setup}
+\label{\detokenize{index:project-environment-setup}}
+To start the project you first need to install all dependencies:
+
+\begin{sphinxVerbatim}[commandchars=\\\{\}]
+\PYG{g+gp}{\PYGZgt{}\PYGZgt{}\PYGZgt{} }\PYG{n}{pip} \PYG{n}{install} \PYG{n}{requirements}\PYG{o}{.}\PYG{n}{txt}
+\end{sphinxVerbatim}
+
+After we have all the requirements set up, we will now create an environment
+
+\begin{sphinxVerbatim}[commandchars=\\\{\}]
+\PYG{g+gp}{\PYGZgt{}\PYGZgt{}\PYGZgt{} }\PYG{n}{conda} \PYG{n}{env} \PYG{n}{create} \PYG{o}{\PYGZhy{}}\PYG{n}{f} \PYG{n}{Softlab}\PYG{o}{.}\PYG{n}{yml}
+\end{sphinxVerbatim}
+
+After the environment is set up you can initialize the environment somehow
+
+\begin{sphinxVerbatim}[commandchars=\\\{\}]
+\PYG{g+gp}{\PYGZgt{}\PYGZgt{}\PYGZgt{} }\PYG{n}{conda} \PYG{n}{activate} \PYG{n}{Softlab}
+\end{sphinxVerbatim}
+
+Yes that was it!! Now simply start the system by typing

+% tabulary has a bug with its re-definition of \multicolumn in its first pass
+% which is not \long. But now Sphinx does not use LaTeX's \multicolumn but its
+% own macro. Hence we don't even need to patch tabulary. See sphinxmulticell.sty

+% \X was chosen to avoid possibility of conflict

+%      exactly \sphinxbelowcaptionspace
+%   b) the space from last baseline of previous text to first baseline of
+%      caption is exactly \parskip+\baselineskip+ height of a strut.
+%   c) the caption text will wrap at width \LTcapwidth (4in)

+%   (with its width or margin option taking place of \LTcapwidth role)

+% 2. interacts very poorly with tabulary.
+%
+% It is needed to write own macros for Sphinx: to allow code-blocks in merged
+% cells rendered by tabular/longtable, and to allow multi-column cells with
+% paragraphs to be taken into account sanely by tabulary algorithm for column
+% widths.
+%
+% This requires quite a bit of hacking. First, in Sphinx, the multi-column
+% contents will *always* be wrapped in a varwidth environment. The issue
+% becomes to pass it the correct target width. We must trick tabulary into
+% believing the multicolumn is simply separate columns, else tabulary does not
+% incorporate the contents in its algorithm. But then we must clear the
+% vertical rules...
+%
+% configuration of tabulary
+\setlength{\tymin}{3\fontcharwd\font`0 }% minimal width of "squeezed" columns
+\setlength{\tymax}{10000pt}% allow enough room for paragraphs to "compete"
+% we need access to tabulary's final computed width. \@tempdima is too volatile
+% to hope it has kept tabulary's value when \sphinxcolwidth needs it.
+\newdimen\sphinx@TY@tablewidth
+\def\tabulary{%
+  \def\TY@final{\sphinx@TY@tablewidth\@tempdima\tabular}%
+  \let\endTY@final\endtabular
+  \TY@tabular}%
+% next hack is needed only if user has set latex_use_latex_multicolumn to True:
+% it fixes tabulary's bug with \multicolumn defined "short" in first pass. (if
+% upstream tabulary adds a \long, our extra one causes no harm)
+\def\sphinx@tempa #1\def\multicolumn#2#3#4#5#6#7#8#9\sphinx@tempa
+   {\def\TY@tab{#1\long\def\multicolumn####1####2####3{\multispan####1\relax}#9}}%
+\expandafter\sphinx@tempa\TY@tab\sphinx@tempa
+%
+% TN. 1: as \omit is never executed, Sphinx multicolumn does not need to worry
+% like standard multicolumn about |l| vs l|. On the other hand it assumes
+% columns are separated by a | ... (if not it will add extraneous
+% \arrayrulewidth space for each column separation in its estimate of available
+% width).
+%
+% TN. 1b: as Sphinx multicolumn uses neither \omit nor \span, it can not
+% (easily) get rid of extra macros from >{...} or <{...} between columns. At
+% least, it has been made compatible with colortbl's \columncolor.
+%
+% TN. 2: tabulary's second pass is handled like tabular/longtable's single
+% pass, with the difference that we hacked \TY@final to set in
+% \sphinx@TY@tablewidth the final target width as computed by tabulary. This is
+% needed only to handle columns with a "horizontal" specifier: "p" type columns
+% (inclusive of tabulary's LJRC) holds the target column width in the
+% \linewidth dimension.
+%
+% TN. 3: use of \begin{sphinxmulticolumn}...\end{sphinxmulticolumn} mark-up
+% would need some hacking around the fact that groups can not span across table
+% cells (the code does inserts & tokens, see TN1b). It was decided to keep it
+% simple with \sphinxstartmulticolumn...\sphinxstopmulticolumn.
+%
+% MEMO about nesting: if sphinxmulticolumn is encountered in a nested tabular
+% inside a tabulary it will think to be at top level in the tabulary. But
+% Sphinx generates no nested tables, and if some LaTeX macro uses internally a
+% tabular this will not have a \sphinxstartmulticolumn within it!
+%

+% Now the branch handling either the second pass of tabulary or the single pass
+% of tabular/longtable. This is the delicate part where we gather the
+% dimensions from the p columns either set-up by tabulary or by user p column
+% or Sphinx \X, \Y columns. The difficulty is that to get the said width, the
+% template must be inserted (other hacks would be horribly complicated except
+% if we rewrote crucial parts of LaTeX's \@array !) and we can not do
+% \omit\span like standard \multicolumn's easy approach. Thus we must cancel
+% the \vrule separators. Also, perhaps the column specifier is of the l, c, r
+% type, then we attempt an ad hoc rescue to give varwidth a reasonable target

+% --- MULTIROW ---
+% standard \multirow
+% 1. does not allow verbatim contents,
+% 2. does not allow blank lines in its argument,
+% 3. its * specifier means to typeset "horizontally" which is very
+%    bad for paragraph content. 2016 version has = specifier but it
+%    must be used with p type columns only, else results are bad,
+% 4. it requires manual intervention if the contents is too long to fit
+%    in the asked-for number of rows.
+% 5. colour panels (either from \rowcolor or \columncolor) will hide
+%    the bottom part of multirow text, hence manual tuning is needed
+%    to put the multirow insertion at the _bottom_.
+%
+% The Sphinx solution consists in always having contents wrapped
+% in a varwidth environment so that it makes sense to estimate how many
+% lines it will occupy, and then ensure by insertion of suitable struts
+% that the table rows have the needed height. The needed mark-up is done
+% by LaTeX writer, which has its own id for the merged cells.
+%
+% The colour issue is solved by clearing colour panels in all cells,
+% whether or not the multirow is single-column or multi-column.
+%
+% In passing we obtain baseline alignements across rows (only if
+% \arraylinestretch is 1, as LaTeX's does not obey \arraylinestretch in "p"
+% multi-line contents, only first and last line...)

+Project : Automated Essay Grader
+**************************************************
+
+**************************************************
+Team Name: Codigos
+Team Members:
+193050021 : Kartavya Kothari
+1930500028 : Aditya Jain
+193050040 : Shreyansh Jain
+**************************************************
+
+
+**************************************************
+Motivation : 
+There are several Issues with manual essay grading such as wastage of man hours, non stan-dardization of checking criterion and inconsistency in grading
+We also focus on Improving the speed of evaluation and fairness
+Automated  essay  grading  and  open-ended  assignments  has  received  increasing attention due to the unprecedented scale of Massive Online Courses(MOOCs)
+More and more students are relying on computers to complete and submittheir school work
+**************************************************
+
+
+**************************************************
+Project environment setup
++++++++++++++++++++++++++
+
+To start the project you first need to install all dependencies:
+
+    >>> pip install requirements.txt
+
+After we have all the requirements set up, we will now create an environment
+
+    >>> conda env create -f Softlab.yml
+
+After the environment is set up you can initialize the environment somehow
+
+    >>> conda activate Softlab
+
+Yes that was it!! Now simply start the system by typing 
+
+    >>> python3 main.py
+
+
+Deployment steps using Docker
++++++++++++++++++++++++++++++
+
+1) You can simply build the the image file by running following in the directory where Dockerfile is present
+
+    >>> docker build --tag essay-grader .
+
+    >>> docker run --name essay-grader -p 8000:8000 essay-grader
