This is an ensemble based spam detection web-application that uses probablistic data-structures based on the paper: A. Singh, S. Batra, Ensemble based spam detection in social IoT using probabilistic data structures, Future Generation Computer Systems (2017), https://doi.org/10.1016/j.future.2017.09.072.

1. Test whether a tweet is spam or ham using the ensemble based spam detection classifier.
2. Type/Paste a single tweet or upload a file to test multiple tweets.
3. Sign-up to create an account and add custom files as database for the classifier model.
4. Login and add/update files from their profile.
5. Classify tweet(s) using model trained from their custom files (Login Required).

1. Quotient filter to quickly and efficiently search the parts of tweet from a list of spam urls, spam users and spam words stored in database.
2. Locally sensitive hashing using MinHash is used to get the jaccard similarity of the input tweet from a set of ham and spam tweets in the database.
3. A Machine Learning model trained on a large dataset of spam and ham tweets. The model uses a pipeline where the tweet goes through CountVectorizer, TfidfTransformer and then using Multinomial Naive Bayes from sklearn library, the model gives the prediction.

1. Install Git Version Control [ https://git-scm.com/ ]

2. Install Python Latest Version [ https://www.python.org/downloads/ ]

3. Install Pip (Package Manager) [ https://pip.pypa.io/en/stable/installing/ ]

1. Create a Folder where you want to save the project

2. Create a Virtual Environment and Activate

Install Virtual Environment First

$  pip install virtualenv

Create Virtual Environment

For Windows

Activate Virtual Environment

For Windows

$  .\env\scripts\activate

For Mac/Linux

$  source env/bin/activate

3. Clone this project

$  git clone https://github.com/Aditya-1500/Spam-Ham-Detection.git

Then, Enter the project

$ cd Spam-Ham-Detection\SMSSpamHam

4. Install Requirements from 'requirements.txt'

$  pip install -r requirements.txt

5. Set Allowed Hosts

• Go to settings.py.
