Re: Seeking Help with finding an assertion

Hello,

About the searching for websites it rung a bell in my head and this
was what I was thinking
http://video.google.com/videoplay?docid=-1882341271080460143
Its a pretty good talk.

About 5 minutes in he talks about navigational queries and cites this paper -
"Understanding user goals in web search"
International World Wide Web Conference  archive
Proceedings of the 13th international conference on World Wide Web
http://portal.acm.org/citation.cfm?id=988672.988675&coll=portal&dl=ACM&type=series&idx=SERIES968&part=series&WantType=Proceedings&title=WWW

Hope that helps,
-Leon
