Description

This Project is part of Data Science Nanodegree Program by Udacity in collaboration with Figure Eight.
The initial dataset contains pre-labelled tweet and messages from real-life disaster.
The aim of the project is to build a Natural Language Processing tool that categorize messages.

The Project is divided in the following Sections:

1. Data Processing, ETL Pipeline to extract data from source, clean data and save them in a proper databse structure
2. Machine Learning Pipeline to train a model able to classify text message in categories
3. Web App to show model results in real time.

Getting Started

Dependencies

• Python 3.5+ (I used Python 3.7)
• Machine Learning Libraries: NumPy, SciPy, Pandas, Sciki-Learn(0.19.1)
• Natural Language Process Libraries: NLTK
• SQLlite Database Libraqries: SQLalchemy
• Web App and Data Visualization: Flask, Plotly

Installing

Clone this GIT repository:

git clone https://github.com/Akshatjain1999/Disaster-Response.git

Executing Program:

1. Run the following commands in the project’s root directory to set up your database and model.

   • To run ETL pipeline that cleans data and stores in database
     python data/process_data.py data/disaster_messages.csv data/disaster_categories.csv data/DisasterResponse.db
   • To run ML pipeline that trains classifier and saves
     python models/train_classifier.py data/DisasterResponse.db models/classifier.pkl

2. Run the following command in the app’s directory to run your web app.
   python run.py

3. Go to the link showed in the command prompt.
