Recipe-Data-Analysis

The Recipe dataset from Kaggle contains over 2 million recipes from all over the world. The dataset contains the dish name, ingredients used and cooking instructions denoted in "directions" column. The author also provides a NER column that applies Named Entity Recognition (NER) on the ingredients and gives the base name of the ingredients used without the brands and quantity used.

This project aims to explore the possibilities opened by the below mentioned questions:

• Question 1: Can clustering techniques be employed to categorize recipes based on their ingredient profiles and identify underlying patterns?

• Question 2: What are the very common ingredients used together?

• Question 3: Given the clusters, and a list of ingredients the user has and their preferred dishes, can dishes be recommended to the user based on the user’s taste?

Since the decompressed dataset is over 2GB, Apache Spark MLlib will be used to analyse the dataset.

The webapp for Question 3 can be accessed here - https://rit-ctrl-recipe-data-analysis-project.streamlit.app/
