  • Patent number: 8478792
    Abstract: Publishers define relationships between their own content items (e.g., World Wide Web pages) and content items created or maintained by other publishers. A central namespace manager provides grouping labels that publishers insert into their content items. Content items having matching grouping labels are identified as related. Different classes of grouping labels can be used to define different types of relationships, and multiple classes of grouping labels can co-exist. Grouping labels are made available to an information server such as a search server, which uses the labels in identifying content items related to a currently displayed content item.

  • Publication number: 20050198319
    Abstract: Techniques are provided for limiting access to Internet content using a parental control filtering system. One or more user systems are connected to the Internet through a network device such as a gateway router. The network device restricts Internet access to pre-selected Internet content in a guest mode without requiring a user to login to a user account. A guest user who does not have a user account is allowed limited access to the Internet through a user system in the guest mode. A user who has a user account can bypass the guest mode and obtain less restrictive access to the Internet by logging into the user account. Parental control settings of any level can be applied to a user account. The parent control setting assigned to a user account are applied to the user system when the user successfully logins to his user account.
