Abstract: A search engine provider interacts with a content provider wherein the content provider provides content to the search engine provider. The content may comprise information that indicates a structure of the content provider's web pages. The search engine may use structural information to classify and extract data items from web pages, and to highlight those data items in search results with labels that identify each such data item's class.

Abstract: Disclosed is a method and system for retrieving data; extracting information from the data; learning to disambiguate the extracted information such that a particular sense of each phrase within the extracted information is determined; generating a disambiguation classifier from the learning to disambiguate step, the disambiguation classifier configured to determine a sense of a phrase within a document; learning to select a portion of the information as being relevant to a theme of the data; generating a selection classifier from the learning to select step, the selection classifier configured to select a topic in a document that is relevant to a theme of the document; and using the disambiguation classifier and the selection classifier by an indexing computer to determine a set of topics from a web document retrieved by the indexing computer.

Abstract: A search engine provider enters into an agreement with a content provider wherein the search engine provider agrees to provide compensation in exchange for the content provider giving content to the search engine provider. The content may comprise data that normally can't be accessed without a subscription, or any other content. The content may comprise information that indicates a structure of the content provider's web pages. The search engine may display normally inaccessible content with search results. The search engine may use structural information to classify and extract data items from web pages, and to highlight those data items in search results with labels that identify each such data item's class. A computing device determines the extent to which enhancement of the search results page using the content provider's content increased the revenue value of the page. The amount paid to the content provider may be based on this extent.

Abstract: An infrastructure facility for interactive commerce in media objects over a network is described. Consumers are provided with searchable access to media object suppliers using standardized commercial packages. A commercial package is associated with a media object by using a commerce tag consisting of embedded metadata to identify the associated commercial package and optionally parameterize a commercial offer. The infrastructure facility provides a searchable database of available media objects with commerce tags, media object suppliers, and an accessible reference for commercial packages and associated tags.
