Message Polarity Prediction: Weekend Hackathon #3

Amal Nair

The third instalment of the adrenaline rush hackathon series is here. This week we challenge the data science community to predict the polarity of a text message or email in MachineHack’s Message Polarity Prediction: Weekend Hackathon #3.

The challenge will start on May 1st, Friday at 6 pm IST.

Problem Statement & Description

All of us receive a ton of messages and emails on a daily basis. Collectively that is a lot of data which can provide useful insights about the messages that each of us gets. What if you could know whether a certain message has brought you good news or bad news before opening the actual message. In this challenge, we will use Machine Learning to achieve this.

Given are 53 distinguishing factors that can help in understanding the polarity (Good or Bad) of a message,  your objective as a data scientist is to build a machine learning model that can predict whether a text message has brought you good news or bad news.

You are provided with the normalized frequencies of 50 words/emojis (Freq_Of_Word_1 to Freq_Of_Word_50) along with 3 engineered features listed below:

  • TotalEmojiCharacters: Total number of individual emoji characters normalized. (eg. 🙂 )
  • LengthOFFirstParagraph: The total length of the first paragraph in words normalized
  • StylizedLetters: Total number of letters or characters with a styling element normalized

Target Variable: IsGoodNews

The data sets will be made available for download on Friday, May 1st 6 pm IST.
