Data Scientist

March 2019 - June 2019

Moderation of online content through NLP and Deep Learning
Classification accuracy of 87%.

I explain the most commonly used techniques to gain meaningful information from text and apply them on a concrete example:
the creation of an algorithm capable of monitoring questions by checking if
a question respects or not the terms and conditions of a question-and-answer website named Quora.
I started by creating statistical features, normalizing the questions and transforming them into a format that classification algorithms can handle.
Finally, I used a Logistic Regression, a Random Forest and a Deep Learning model to predict if the questions were compliant or not.
The best algorithm reached an accuracy of 87%.
