Today fake news on social media is big problem. Its damage peoples honor. So, Fake news detect on social media is a major solution.

3. INTRODUCTION
• Fake news exist way before social media but it multifold when social media was
introduced
• Fake news is a news designed to deliberately spread hoaxes, propagenda and
disinformation
• Fake News Stories usually spread through social media sites like Facebook,
Twitter etc

4. BACKGROUND
• Social media is used for news reading
• Source of the news
• Proffession used to distribute the news in the past
• Nowadays , everybody wants to be a journalist .
• People are profiting by clickbaits and publishing fake news on online
• More clicks contribute to more money for content publishers.

5. MAJOR PROBLEMS
• By clicking on clickbait, users are led to page that contains false information.
• Fake news influences people’s preceptions.
• The rise of Fake news has become a global problem that even major tech companies like
Facebook and google are struggling to solve.It can be difficult to determine whether a text is
factual without additional context and human judgement

6. PURPOSE
• This project aims to develop a method for detecting classifying the news stories
using Natural Language Processing.
• The main goal is to indentify fake news, which is aclassic text classification issue.
• We gathered our data , preprocessed the text, and translated our articles into
supervised model feautures.
• Our goal is to develop a model that classifies a given news article as either fake or
trure.

7. DELIMITATIONS
• Our system does not guarantee 100% accuracy
• The system is unable to test data that is unrelated to the training database

8. TYPES OF FAKE NEWS
Visual based type
Visual based are mainly photoshopped images and videos which are
posted in social medias
Linguistic based type
Linguistic based are mainly the manipulation of text and string
content/ This isssues is with blogs , news , or emails

9. DATA SET
 Datasets are collected reaseech purposes with help of kaggole websites
 Our data is preleveled with fake and real news
 30% of the data is used for training the Ml Model
 70 of the data is used to test the model

10. WORKFLOW
• The steps in this procedure are as follows:
• Data set loading
• Data pre processing (remove stop words,
streaming, Drop duplicate and remove
meaningless char from the text.)
• Feauture Selection
• Applying Classifiication and model Consruction
• Classifying the new data

11. CONFUSION MATRIX
A confusion matrix is a table that is used to
define the performance of a classification
algorithm. A confusion matrix visualizes and
summarizes the performance of a
classification algorithm.

12. METHODOLOGY
1. Data collection
2. Data preprocessing
3. Model implementation

13. DATA COLLECTION
• In this paper, we used a dataset which collected from Kaggle[28].There are two dataset.
One of them includes real data, while the other ones contain fake data. True dataset
consists of 21417 data and Fake dataset consists of 23481 data.Title, text, subject, and
date are the four features present in both datasets. Text, Title and Subject which
attributes are contain qualitative data means all is textual data and Subject represent
categorical data.
DATA PREPROCESSING
• Both organized and unstructured data might be included. Unstructured data is that which does not adhere to all of the
grammar rules and may contain typos and slang. Structured data adheres to proper grammar standards. Both organized and
unstructured data do not produce the greatest outcomes. It is advisable to utilize data with a semi-structure. Data that is
partially organized but not completely unstructured is referred to as semi-structured data. It stands in between the two.We use
NLP.
• Eliminate punctuation
• Tokenization
• Stopwords
• Stemming

14. MODEL IMPLEMENTATION
• Logistic Regression
• Decision Tree
• Random Forest
• Gradient Boosting
• Naïve Bayes
 At present, one of the most popular methods is machine learning. First we taken a dataset for
implementation .But we need to modify this dataset before applying classifiers. There are two
dataset. Purpose of our work ,we need to merge our two dataset and also add a categorical
features (class) which make sure the news is true or fake. So, we preprocessing the data which
will eventually increase the performance of our model and the text data is converted into a
numerical vector during vectorization. After completing we applied some classifiers--

15. RESULT
• For implementation and better results, we produced a dataset in the form of a CSV
file. We taken this dataset from Kaggle. And two dataset are merged for applying
classifiers and get best performance. Additionally, a google colab was developed to
put the ML program into practice. We have employed decision trees, random
forests, gradient boosting, logistic regression, and k-nearest neighbors. The
accuracy for Logistic Regression is 0.99%, Decision Tree, Naïve Bayes is 0.93 . For
Decision Tree, it was 0.99%, for Random Forest, it was 0.98%, and for Gradient
Boosting Classifier, it was 0.99%.
• Classifiers are models that are applied to both training and testing sets of data.
Accuracy is the proportion of times an algorithm successfully classifies a data point.
Precision is calculated as the ratio of correctly anticipated positive observations to
all positively predicted observations.

16. CONCLUSION
• All classifiers have these prediction values calculated, and the final percentage is determined
by averaging all of these prediction values. Using these metrics. In order to determine the
percentage of news that is accurate, we are setting a range. The news is being displayed first,
then the result, on the webserver we built. We used certain emoticons as a symbol to more
effectively display the results and draw users' attention. A platform-independent web server
has been developed. It implies that every configuration of the webserver will be device-
independent. We used Bootstrap to make our web server independent of hardware. The
resultant output takes the form of a message that varies depending on certain
percentages.These prediction values are computed for each classifier, and the final 97.8 % is
obtained by averaging all of these prediction values. These metrics are used. We are
establishing a range to determine the proportion of news that is accurate. On the webserver
we constructed, the news is displayed before the outcome. To capture users' attention and
more effectively convey the results, we employed specific emoticons as a sign. A web server
that works on any platform has been created. It indicates that each webserver setup will be
independent of the device. To make our web server independent of hardware, we used
Bootstrap. The output that results is a message that changes based on specific percentages.
