In this online event, Katie Gross (Lead Data Scientist, Dataiku) walked through a project built in Dataiku DSS using NLP on data from popular cooking sites, to predict whether a recipe is likely to be highly rated.


Presentation abstract:
Want to judge whether your recipe will be a hit? Or in general, what user-generated content is likely to lead to high engagement? We developed a workflow in Dataiku DSS that uses NLP to predict which recipes are likely to be highly rated. We’ll walk you through how we webscraped text recipes from popular recipe-sharing sites like Allrecipes and Epicurious, cleansed and prepared the data, and built a machine learning model to predict ratings of future recipes.
What's discussed:
  • NLP is a field of AI that enables machines to read, understand, and derive meaning from human languages.
  • Utilizing a Text Featurization Pipeline to convert text into features of a machine learning model: this includes Preprocess Text (normalize, remove stop words, stem, and tokenize) so "I was running to the river and jumped over a log" is processed to ["i", "run", "river", "jump", "log"].
  • Vectorizing the text (converting to numeric features) utilizing either Count Vectorization or Term Frequency-Inverse Document Frequency (TF-IDF).
  • Deep dive of recipe reviews in Dataiku DSS.
