Abstract: The present invention provides methods and apparatus, including computer program products, implementing techniques for searching and ranking linked information sources. The techniques include receiving multiple content items from a corpus of content items; receiving digital signatures each made by one of multiple agents, each digital signature associating one of the agents with one or more of the content items; and assigning a score to a first agent of the multiple agents, wherein the score is based upon the content items associated with the first agent by the digital signatures.

Abstract: Data is identified from one or more data sources, where the data is associated with at least one structured document. Data sets contained within the at least one structured document are extracted, and one or more record items are added to a searchable database, where the one or more record items correspond to the extracted data sets.

Abstract: Systems, methods, and computer program products for automating local content are described. In some implementations, an ad manager and a business table can be provided by a backend system. The business table can store, for example, user information, user account information including billing information, campaign related information and advertisement data associated with one or more local business advertisers as well as geo-targeting information. Based on the information stored in the business table, the ad manager can tailor a specific online advertising campaign on behalf of a local business advertiser. Where new or updated information is found, the ad manager can initiate campaign management updates to one or more business ad listings associated with the local business advertiser.
