Abstract:
1. A computer implemented method, comprising: determining statistics for each of a plurality of Web pages with respect to one or more predetermined categories based on content rating of each of the Web pages; and for each of the predetermined categories, selecting a set of primary Web pages having relationships with one or more secondary Web pages, wherein the one or more secondary Web pages probabilistically distinguish from relationships with a remainder of the secondary Web pages, wherein the selected set of primary Web pages having relationships with one or more secondary Web pages are used by a network access device to determine a probability that a particular Web page received at the network access device responsive to a request by a client belongs to one or more of the predetermined categories based on a linking pattern of the particular Web page linked with other Web pages using content ratings of the selected set of primary Web pages and the associated secondary Web pages, wherein the network access device is a gateway device that interfaces the client of a local area network (LAN) with a Web server of an external network, wherein the particular Web page is routed exclusively through the gateway device from the external network to the client with the gateway device acting as a sole interface between the LAN and the external network for the purpose of downloading a Web site, and wherein the determined probability of the particular Web page is used by the network access device to determine whether the particular Web page should be delivered to the client over the LAN.
