CNN for Query Categorization in ​ E-Commerce

Submitted by Deepak Arora (@deepakarora) (proposing) 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.

Session type: Short talk of 20 mins Status: Rejected


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.

    Hi Deepak,

    Thank you for submitting a proposal. We need to see detailed slides and a preview video to evaluate your proposal. You’ve also proposed this on behalf of someone, but your slides indicate otherwise. Do correct this or share the bio of the person you’d like to speak on this. Your slides must cover the following:

    • Problem statement/context, which the audience can relate to and understand. The problem statement has to be a problem (based on this context) that can be generalized for all.
    • What were the tools/frameworks available in the market to solve this problem? How did you evaluate these, and what metrics did you use for the evaluation? Why did you pick the option that you did?
    • Explain how the situation was before the solution you picked/built and how it changed after implementing the solution you picked and built? Show before-after scenario comparisons & metrics.
    • What compromises/trade-offs did you have to make in this process?
    • What is the one takeaway that you want participants to go back with at the end of this talk? What is it that participants should learn/be cautious about when solving similar problems?

    We need your updated slides and preview video by Jun 27, 2019 to evaluate your proposal. If we do not receive an update, we’d be moving your proposal for evaluation under a future event.
