He was a guest lecturer in the Berkeley course INFO 141 Search Engines: Technology, Society, and Business. He talked about some of the challenges to figuring out what people want from their searches in Google. For example
- when a person is on the Google home page and types in google as a search term, what do they want?
- since people don't notice most of the things on a screen how do they guide the user to the right part of the screen?
- chronological ordering the results of a Scholar search is difficult at best and impossible when the publishers don't include dates in their metadata
- people's skills are very uneven because they learn search skills from someone else (not the manual)
- building an advanced search page that doesn't scare people is very difficult
He also talks about how they do their user observation studies.
