1. A system that facilitates determination of search query answers, comprising: a processor that executes computer executable components stored in a memory: an extraction component that crawls content located via multiple sources on a network and obtains, at crawl-time, structured content along with associated metadata; an indexing component that indexes the structured content from the extraction component based at least on the associated metadata, and stores the indexed structured data in a database; a query response component that employs the indexed structured content to determine a plurality of query answer strings in response to receiving a user query, wherein the query response component: parses the user query to ascertain a question focus and an answer type; searches the indexed structured content stored in the database for the question focus and identifies the plurality of query answer strings that conform with the answer type in accordance with one or more relationships specified by the obtained structured content; and provides feature information included in a feature vector for each of the plurality of query answer strings, wherein the feature information includes a set of features that describe characteristics of an answer, the set of features including at least one source feature relating to a source from which a particular string of information was extracted, and at least one answer type feature relating to an intrinsic property of an actual query answer string; and a ranking component that utilizes the feature vectors to automatically order a top K number of query answer strings, where K is an integer from one to a total number of available query answer strings.
