CNN for Query Categorization in ​ E-Commerce

Submitted by Deepak Arora (@deepakarora) on Jun 14, 2019

This is a proposal requesting for someone to speak on this topic. If you’d like to speak, leave a comment.

Query categorization is a fundamental problem in e-commerce.
For a query, find most relevant category of products.
Think about it:
Apples bought from electronics do not taste sweet.
Apples at Grocery Store don’t have OS.
Queries have multiple tokens. Longer the query , less products supporting it.
Milk 2 % and 2% Milk probably mean the same product.
