He reportedly also outlined some of the key DB application challenges Google is working on: schema auto-complete, synonym discovery, creating entity lists, association between instances and aspects, and data level synonyms discovery...
I really like Alon's research. See also Google's Deep Web Crawl and Web-scale Data Integration: You can only afford to Pay As You Go
