We introduce a grocery retrieval system that maps shopping
lists written in natural language into actual products in a
grocery store. We have developed the system using nine
months of shopping basket data from a large Finnish supermarket.
To evaluate the system, we used 70 real shopping
lists gathered from customers of the supermarket. Our system
achieves over 80% precision for products at rank one,
and the precision is around 70% for products at rank 5.
