The tutorial gives an overview of the characteristics of search queries, when considered as an input data source in open-domain information extraction, and their impact on extraction methods operating over queries as opposed to documents; types of knowledge for which queries lend themselves as a useful data source in information extraction; detailed methods for extracting classes, instances and relations from queries; and implications in semantic annotation of queries, understanding query intent, and information access and retrieval in general.
