# PyCon APAC 2023 Tech Talk - AI for Efficient Routing of Customer Inquiries at Mercari



I gave my first-ever tech-talk at a conference at [PyCon APAC 2023](https://2023-apac.pycon.jp/) on Friday, October 27th. I mostly talked about how we use AI in customer support operation at Mercari. The takeaways from the talk are:



- Translating a business problem into an ML one

- Solving the ML problem using NLP and Python

- Insights into the routing of customer inquiries



If you're interested in the use of AI for improving customer support operations, you'll find this talk worthwhile!



You can find the video of the talk and the slides that I used here as well as the proposal that I submitted for the talk.

## Proposal



### Abstract



One of the most significant challenges in efficiently handling customer inquiries is routing inquiries to the appropriate customer support agent with the right skills and knowledge to provide prompt and accurate responses. This talk will explore how we use AI for skill-based routing of customer inquiries at Mercari and its business impact.



### Description



Customer support operations can be a significant cost center for businesses. The volume of customer inquiries also grows as a business grows, but the customer support team can't scale linearly with the business. Efficient and effective handling of customer inquiries is the key to keeping the customer support operation costs in check without compromising customer satisfaction. One of the most significant challenges in efficiently handling customer inquiries is routing inquiries to the appropriate customer support agent with the right skills and knowledge to provide prompt and accurate responses. If we fail to route the inquiries to suitable agents, it can lead to long wait times and unsatisfactory resolutions for customers.



In this tech talk, we will explore how AI can be used to predict the skill required to handle customer inquiries. We will discuss the challenges involved in an AI-based routing system, including data collection, model training, and deployment. We will also develop the benefits of AI-based routing, such as a lesser number of transfers, a reduction in customer support operation costs, and a reduced workload for support agents.
