Abstract: A graphical user interface includes tabs representative of different classes of search results. The tabs are derived in response to the processing of a query. The different classes of search results group content by meaning, such that a query term with different meanings produces different classes of search results with different meanings.

Abstract: A graphical user interface includes tabs representative of different classes of search results. The tabs are derived in response to the processing of a query. The different classes of search results group content by meaning, such that a query term with different meanings produces different classes of search results with different meanings. Further, stacks associated with each tab are derived. Each stack shares common attributes associated with a tab but has a refined meaning representing a different class of search results. Each stack includes text to characterize a class of search results.

Abstract: A graphical user interface includes configurable parameters to format search results. The configurable parameters include configurable parameters to specify column configuration and textual summary length.

Abstract: A graphical user interface includes a listing of results derived from processing a query. The graphical user interface further includes a menu of refining search terms that is dynamically derived in response to the processing of the query.

Abstract: A graphical user interface includes a scroll area displaying search results and a permanently displayed anchored area.

Abstract: A graphical user interface includes a document retrieved by processing a query. The graphical user interface further includes an advertisement selected based upon the document. The advertisement may include an image, text or an icon.

Abstract: A graphical user interface includes stacks organizing different classes of search results. The stacks are derived in response to the processing of a query. The different classes of search results group content by meaning, such that a query term with different meanings produces different classes of search results with different meanings.

Abstract: Disclosed are a system, method, and program storage device implementing the method of extracting information, wherein the method comprises inputting a query; searching a database of documents based on the query; retrieving documents from the database matching the query using a plurality of classifiers arranged in a hierarchical cascade of classifier layers, wherein each classifier comprises a set of weighted training data points comprising feature vectors representing any portion of a document; and weighing an output from the cascade according to a rate of success of query terms being matched by each layer of the cascade, wherein the weighing is performed using a terminal classifier.
