SIGIR 2009 Best Paper Award Goes to...

Sources of Evidence for Vertical Selection (ACM DL link) by Jaime Arguello (Carnegie Mellon University), Fernando Diaz (Yahoo! Labs Montreal, UMass Alum), Jamie Callan (Carnegie Mellon University, UMass Alum), Jean-Francois Crespo (Yahoo! Labs Montreal)
Vertical selection is the task of selecting the relevant verticals, if any, in response to a user's query. We focus on single vertical selection, defined as the task of predicting a single relevant vertical.
They looked at 18 different verticals and compared how their vertical selection methods compared with prior work on federated search. They used:
  1. Query string features which used key phrases in the query ("weather", "movies", etc...)
  2. Query log features which used the likelihood of the query given past queries on the vertical
  3. Corpus features which uses documents retrieved from the different verticals.
My congratulations to Jaime, Fernando, Jamie, and Jean-Francois!

(Note: Since the best paper was from a student there was no separate best student paper award)
