Problem Statement & Description

The last two decades have witnessed a significant change in how consumers purchase products and express their experience/opinions in reviews, posts, and content across platforms. These online reviews are not only useful to reflect customers’ sentiment towards a product but also help businesses fix gaps and find potential opportunities which could further influence future purchases. 

To that end, Ugam, a Merkle company, in association with MachineHack, is inviting the entire machine learning community to develop a machine learning model that can analyse customers’ sentiments based on their reviews and feedback.

Unlike typical sentiment analysis problems, this challenge isn’t as simple as it appears to be and thus gives an opportunity for the participants to come up with some innovative solutions and gauge their data science knowledge. This hackathon is not your average sentiment analysis problem, rather goes beyond. 

Participants of this hackathon will get to analyse and deep dive into the natural language text (reviews) and bucket them based on their discussion topics. Plus, they will get to analyse the overall sentiment of the business to make tangible decisions. 

MachineHack and Ugam have created a training dataset of 6136 rows with 14 columns and a testing dataset of 2631 rows with 14 columns to solve the sentiment analysis problem. The dataset will be a mix of customer reviews for products across categories and retailers. 

The participants need to develop a model that can bucket the future reviews in their respective topics, where a review can talk about multiple topics and overall polarity, i.e. positive/negative sentiment.

The hackathon demands a few prerequisite skills such as text pre-processing – Lemmatization, tokenisation, N-Grams and other relevant methods, along with multi-class classification and optimising Log Loss.

Submission Guidelines

The participants must submit a .csv/.xlsx file with exactly 2631 rows with 12 columns . The submission will return an ‘Invalid Score’ if any extra columns or rows are presented. 

Sklearn models support the predict_proba() method to generate the predicted values.

Evaluation Criteria

The evaluation of the hackathon will be done using the Log Loss metric. One can use sklearn.metric.log_loss to calculate the same.

The hackathon will also support private and public leaderboards, where the public leaderboard will be evaluated on 70% of test data. On the other hand, the private leaderboard will be available at the hackathon’s end and assessed on 100% of test data.

The final score will represent the score achieved based on the ‘Best Score’ on the public leaderboard.

Prizes

Ugam will select the top three (3) winners based on the given criteria. The prize money is for interested candidates willing to get interviewed/hired by Ugam.

First Prize: INR 40,000

Second Price: INR 20,000

Third Prize: INR 10,000

The hackathon will end on January 10, 2021 at 6:00 PM.
