Creating a Fake News Dataset using Python

In this article, we will explore how to create a fake news dataset using Python. We will be using the Pandas library for data manipulation and the random library for generating random values.

Introduction

Fake news is a growing concern in today’s digital age, with many websites and social media platforms spreading false information to mislead or manipulate their audience. Creating a fake news dataset can help researchers and machine learning engineers train and test their models on realistic data.

In this article, we will cover the following topics:

• Creating a fake news dataset using Python
• Understanding the importance of datasets in machine learning
• How to use Pandas for data manipulation

Why Datasets Matter

Datasets are essential in machine learning as they provide the training data that algorithms learn from. The quality and accuracy of the dataset directly impact the performance of the model.

In this case, our goal is to create a fake news dataset that mimics real-world data. This will allow us to train and test our models on realistic data, which can help improve their accuracy and robustness.

Creating the Fake News Dataset

To create our fake news dataset, we’ll use Python’s Pandas library for data manipulation and the random library for generating random values.

import pandas as pd
import numpy as np
from datetime import date, timedelta

First, let’s define our dataset structure. We want to create a DataFrame with 15 columns, each representing a different feature of our fake news article:

• profileid: Unique identifier for the profile of the author
• profilename: The name of the profile
• dateofjoin: The date when the author joined Facebook
• allfriends: Number of friends in the profile
• profilepicture: Profile picture URL or ID
• numberofgroupjoins: Number of groups joined by the author
• numberofpagelikes: Number of likes on the author’s page
• newspost: Whether the author has made a news post
• profilewithphotoguard: Whether the profile picture has photo guard
• numberofsharedstories: Number of shared stories by the author
• numberoffollowers: Number of followers of the author’s page
• numberofevents: Number of events attended by the author
• numberofsharedposts (image, text, video): Number of posts shared by the author in different formats
• numberofurlshared: Number of URLs shared by the author
• numberoftags: Number of tags used by the author

Here’s how we can define our dataset structure using Pandas:

dataset = pd.DataFrame(
    columns=[
        'profileid',
        'profilename',
        'dateofjoin',
        'allfriends',
        'profilepicture',
        'numberofgroupjoins',
        'numberofpagelikes',
        'newspost',
        'profilewithphotoguard',
        'numberofsharedstories',
        'numberoffollowers',
        'numberofevents',
        'numberofsharedposts (image, text, video)',
        'numberofurlshared',
        'numberoftags'
    ],
    index=[np.nan]  # Add a row with NaN values for demonstration purposes
)

Now that we have our dataset structure defined, let’s populate it with random data.

Populating the Dataset

We’ll use Python’s random library to generate random values for each column in our dataset. Here’s how we can do this:

for i in range(15000):
    dataset.loc[i] = [
        np.random.randint(0, high=5000),  # profile id
        'User' + str(np.random.randint(0, high=5000)),  # profile name
        date(1970) + timedelta(np.random.randint(0, 365 * 24 * 60 * 60)),  # date of join
        np.random.randint(0, high=5000),  # all friends
        np.random.randint(0, high=2),  # profile picture
        np.random.randint(0, high=1000),  # number of group joins
        np.random.randint(0, high=1000),  # number of page likes
        np.random.randint(0, high=1000),  # news post
        np.random.randint(0, high=2),  # profile with photo guard
        np.random.randint(0, high=1000),  # number of stories shared
        np.random.randint(0, high=1000),  # number of following
        np.random.randint(0, high=1000),  # number of events
        np.random.randint(0, high=1000),  # number of shared posts (image, text, video)
        np.random.randint(0, high=1000),  # number of URL shared
        np.random.randint(0, high=1000),  # number of tags
        np.random.randint(0, high=1000),  # number of hashtags
        np.random.randint(0, high=1000),  # number of newly added friends
        np.random.randint(0, high=2),  # recent post liked or shared
        np.random.randint(0, high=2),  # current location
        np.random.randint(0, high=1000),  # messages with spam words
        np.random.randint(0, high=2),  # source
        np.random.randint(0, high=1000),  # headline
        np.random.randint(0, high=1000),  # body text
        np.random.randint(0, high=1),  # text
        np.random.randint(0, high=1),  # images (with text or with hyperlink)
        np.random.randint(0, high=1),  # videos
        np.random.randint(0, high=999999999),  # linguistics based (chapter, word, sentence, document, quoted word, external link, etc.)
        np.random.randint(0, high=999999999),  # StatisticalFeatures (count, ImageRatio, MultiImageRatio, HotImageRatio, ShortImageRatio)
        np.random.randint(0, high=1),  # Images (ClaritySource, Coherence, SimilarityDistribution, DiversitySource, ClusteringScore)
        np.random.randint(0, high=999999999)  # PostDate
    ]
)

This code will populate our dataset with 15 columns of random values. We can save the dataset to a file for future use.

Conclusion
