We showcase the use of Neo4j as a backend to our AI technology in eBay's virtual shopping assistant: eBay ShopBot. We will discuss how we used Neo4j as a probabilistic graph model to drive conversations. We also touch upon the key learnings for deployment and scalability in Google cloud platform. We will touch upon the following application oriented learnings of using neo4j for a year in production:
1. How we deploy at scale in GCP, how we scaled to 1TB graph data
2. How neo4j can form the backend for a conversational engine like shopbot
3. Discussions and recommendations on the use of procedures against cypher in Neo4j
4. Future plans
