Sorry for the short notice and the early starting time, but if you can make it, this sounds like it will be a great talk. Levine Hall, by the way, is Penn's shiny new Computer Science building. It's somewhat hidden between 33rd St., 34th St., Walnut St., and Locust Walk.

Google faces two large technical challenges: ensuring that our search results are as relevant as possible, and serving hundreds of millions of queries in a fraction of a second at a reasonable cost. To solve the first problem, we perform an offline matrix computation to produce PageRank, a query independent measure of page reputation, and combine it with more traditional query-specific scoring. To solve the distributed computing problem, we use tens of thousands of commodity PCs and highly fault-tolerant software. I will discuss some details of these solutions, and also share some interesting statistical tidbits about search and the web.
