Abstract: The technologies described herein serve contextually relevant advertisements under a guaranteed advertisement campaign. A publisher retrieves a guaranteed advertisement campaign related to a webpage available for serving an advertisement, and identifies a set of advertisements relating to the guaranteed advertisement campaign. Advertisement selecting circuitry of the publisher determines whether an advertisement that is contextually relevant to content published at the webpage is present in the set of advertisements. If there is no contextually relevant advertisement in the set of advertisements, the advertisement selecting circuitry selects an alternative advertisement from the set of advertisements that minimizes an under-delivery risk related to the guaranteed advertisement campaign. If there is a contextually relevant advertisement in the set of advertisements, the advertisement selecting circuitry selects the contextually relevant advertisement.

Abstract: The present invention provides a method and system of manipulating XML data in support of data mining. In an exemplary embodiment, the method and system include (1) storing the XML data in a network format to a buffer, thereby resulting in a stored network representation of the XML data and (2) selecting at least one feature of the XML data via a naive selection operating on the stored network representation of the XML data. In an exemplary embodiment, the method and system include (1) storing the XML data in a network format to a buffer, thereby resulting in a stored network representation of the XML data and (2) modifying at least one feature of the XML data via a naive modification operating on the stored network representation of the XML data. In an exemplary embodiment, the network format includes xtalk format.
