The package includes the following files:

-data_extraction.py: The data extraction script extracts the relevant data from the corpus and creates a CSV corpus.csv to store the data in a format that can be used by the system -SVMClassifier.py: implements the Linear SVC SVM Classifier and returns a list of classified output labels for the test data -corpus.txt: This is the corpus that is used for the project, this file can be stored at any desired path. When the data_extraction.py script is run, the system prompts the user to enter the path of the location where this file is stored) -README.txt

Instructions:

1. Install the required libraries, the system needs the following import statements to import the required libraries:

import glob import numpy import pandas as pd import matplotlib.pyplot as plt import seaborn as sns from sklearn.preprocessing import LabelBinarizer from sklearn.feature_extraction.text import (CountVectorizer, TfidfTransformer) from sklearn.multiclass import OneVsRestClassifier from sklearn.svm import LinearSVC from sklearn.pipeline import Pipeline from sklearn.cross_validation import KFold from sklearn.metrics import (confusion_matrix, classification_report, accuracy_score) from sklearn.calibration import (calibration_curve, CalibratedClassifierCV)

2. Save the corpus.txt file on disk

3. Run the data_extraction.py script and provide the required input (i.e. file path to the corpus.txt)

4. Run the SVMClassifier.py script and provide the required input

5. A heatmap of the confusion matrix (percentage), accuracy score and classification report are printed
