Propaganda is a form of communication that is aimed at influencing the attitude of a community toward some cause or position. It often presents facts selectively to encourage a particular synthesis. The disinformation damages the reputation of respectable news outlets, organisations and very bad for business indeed. The objective of the Hackathon is to be able to detect the Propaganda and Non-propaganda news as well as to develop a model that can help with the venture. The other objectives of this work includes detecting phrases which are propagandist and also finding out the type of propaganda it is. The algorithms that we will be taking help from are Passive Aggressive, Multiple Layer Perceptron Network, Logistic Regression, AdaBoost, Decision Tree, Random Forest, KNN, SVM and Naive Bayes to detect the potentially propagandistic and non-propagandistic sentences in a news article. For the evaluation, we are calculating F1 Score to measure the class imbalance in the testing dataset. We have used the best model for detecting propagandist and non-propagandist articles, phrases and also type of propaganda.

News is the lifeline of the human society , it underlines all the important events and influences public opinion like no other tool , but with the recent advent of electronic media and the sheer amount of new being churned out and the current political climate it’s hard to figure out what’s genuine news and what’s propaganda , this is where intelligent systems which can classify news articles , text fragments as propagandistic or non-propagandistic comes into play , this Datathon is focussed on developing such a system using various algorithms and methods to predict such a scenario the levels of challenges are:

A System that is able to classify a news article whether it is propaganda or not.
A System that is able to classify whether a sentence in a article is propaganda or not.
A System that is intelligently able to classify the propaganda technique used in the new piece.
