eBay HelpBot

Live now in the UK for hundreds of thousands of users, the HelpBot is a product backed by a machine learning-based natural language understanding engine to take care of issues on the member’s behalf. Users can submit returns, get refunds, or have disputes with sellers adjudicated without even having to leave the page.

Launched a new machine learning classifier-based search engine for the eBay Help platform in Australia, which is seeing a large improvement over the prior Oracle-based keyword search engine in terms of click-through rate, average click position, and search comprehension.

Launched a routing system utilizing the HelpBot's natural language understanding capabilities to reduce contact transfer rate in eBay's contact centers (transfers are a bad experience for the user, and expensive for eBay). This routing application identifies the user's issue from a brief description and connects them with the correct staffgroup.

Based on the tutorial by Siraj Raval with quite a few modifications. This convolutional neural network model is trained on the MNIST dataset using the Keras API and TensorFlow as a backend. The application itself is deployed on Heroku, using Flask and Gunicorn to serve.
