Portal web search engines must support a wide variety of user queries. Those queries which deal with late-breaking news or emerging topics are amongst the most difficult classes of queries for a search engine to support. In this presentation, I will be describing the detection of queries on emerging topics and how a search engine can best support them. Topics will include automatic query classification, news vertical federation, web resource discovery, and ranking.
