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.
