  • Dynamic background rater for internet content
    Patent number: 7587488
    Abstract: The present invention extends to methods, systems, and computer program products for dynamically rating Internet content. A computer receives an indication that at least one URL is available to be rated and that resources (e.g., a content rater) are available for rating the URL. The computer selects a URL, which identifies a portion of Internet content, and transfers the URL to at least two different content classifiers. The computer accesses first rating data corresponding to the identified portion of Internet from a first content classifier. The computer accesses second rating data corresponding to the identified portion of Internet from a second content classifier. The computer combines at least the first rating data and the second rating data into a combined rating corresponding to a specified content category. The computer indicates that the identified portion of Internet content is included in the specified content category.
