How far is the Empire State Building from the Eiffel Tower? 0.22

… and both are 0.14 from the keyword "summit". This talk describes how we use semantic vectors to improve the discovery experience of our online travel marketplace. We apply such text-based embeddings for recommendations, ranking, and ad optimisation. The applied algorithms have evolved over time, starting with a slightly twisted application of word-2-vec to fine-tuning pre-trained BERT models on our own data. We will try to share helpful advice from the application side like how we applied simple vector arithmetics to improve results.
