Christian06.01.2023Rethinking semantic product search: a new approach to queries with unusual spelling variations
In recent years, semantic product search has been widely adopted in global e-commerce. However, many systems exhibit issues in understanding queries with unusual spelling variations. In this blogpost, we show you how Otto’s Team Turing has developed a new system that alleviates these problems. It is live and has lifted the Click-Through Rates (CTR) in the low-recall segments of otto.de by more than 25% and the Conversion Rate (CvR) in the low-hit segment by more than 90%.development
Guido01.12.2022Scaling Agile @ OTTO
Agile Development is definitely nothing new at OTTO – the term has long since reached Peak Hype.

Andreas, Philipp01.11.2022Kaggle: Machine Learning competition for the best Multi-Objective Recommender System
Major online retailers such as OTTO offer their customers millions of products to explore and purchase. However, finding the right product from such a vast selection without a little guidance can be exhausting! So we work to guide our customers to those products that best match their interests and motivations using personalised recommendations. For this reason we want to enhance our ability to forecast in real time which products each customer will want to see, add to their cart and order at any given moment of their visit.development
