Two Zillow Presentations that Explains how Zillow works

I discovered the following two presentations that explains how Zillow works:

Zillow: Disrupting the Real Estate Marketplace with Data

• 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.

How Zillow uses Machine Learning to Transform Real Estate

• 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.
