AI Driven Search

Nextdoor is the diverse multi-sided marketplace where on the one side we have neighbors having the most diverse sets of intents. Their interests are explicitly expressed in the search bar and form quite a unique demand vector. People are searching for local neighbors to connect with, trying to find classifieds or recommendations for their next pet projects just to name a few. At the same time, with the latest advances in the area of Machine Learning and AI, the modern search needs to be intelligent, domain-aware, contextual, and personalized. Using these guiding principles, the Search Team at Nextdoor has built modern, AI-Powered Search. In this talk, we will present the search advances we have conducted in the area of Query Understanding, Recall, and Ranking using principles we have listed above.
