I discovered the following two presentations that explains how Zillow works:
- Stan Humphries, Chief Economist from Zillow, talks about what data Zillow has, how Zillow thinks about big data, what applications Zillow builds on top of the data, a little bit about the technical infrastructure, and what questions the data allows Zillow to answer in terms of the real estate marketplace.
- Zillow pioneered providing access to unprecedented information about the housing market. Long gone are the days when you needed an agent to get comparables and prior sale and listing data. And with more data, data science has enabled more use cases. Jasjeet Thind explains how Zillow uses Spark and machine learning to transform real estate.
