The challenge

Train a Machine Learning model to categorize products’ listing based on their titles.

MercadoLibre hosts millions of products and services listings. Having structured data describing each of them is a key factor providing the best customer experience by facilitating product search and discovery, improving recommendations, providing comprehensive technical datasheets, package size estimations, among other possibilities.

That's why it is vital that each listing is properly classified (whether it's a cell-phone, a refrigerator, a television, etc.). However, given the variety of products in our market and thousands of available categories, choosing the right category might be a difficult task.

Given a listing title, we challenge you to predict the best fitting category.
