Abstract: A method and system for associating keywords with online content sources. According to one embodiment, a method may include identifying a result set including one or more of a plurality of online content sources, wherein each of the included one or more online content sources satisfies a keyword query including one or more keywords. The method may further include, for a given one of the online content sources included in the result set, identifying one or more aggregate paths including the given online content source, wherein a given one of the one or more aggregate paths includes one or more navigation paths among the plurality of online content sources, and in response to detecting a selection of a particular online content source from one of the identified aggregate paths, associating the one or more keywords included in the keyword query with the particular online content source.

Abstract: A method and system for determining and notifying users of undesirable network content are disclosed. According to one embodiment, a method may include detecting an adverse content event corresponding to a given network information source, where the adverse content event occurs dependent upon activity of a given user with respect to the given network information source. The method may also include reporting the adverse content event with respect to the given network information source, detecting a reference to the given network information source on behalf of a particular user, and in response to detecting the reference, retrieving an indication corresponding to the given network information source, where the indication is determined dependent upon adverse content events reported with respect to the given network information source. The method may further include notifying the particular user of possible undesirable content with respect to the given network information source dependent upon the indication.

Abstract: A method and system for determining interest levels of online content navigation paths. A method may include determining each of a plurality of navigation paths among a plurality of online content sources, and for each of the navigation paths, determining a corresponding path weight, where a given corresponding path weight is indicative of user activity along a corresponding navigation path. The method may further include identifying a particular aggregate path within the online content sources, where the particular path includes some of the navigation paths, where an aggregate path weight corresponding to the particular path is dependent upon the path weights corresponding to the navigation paths included in the particular path, and where the aggregate path weight satisfies an optimization criterion relative to other aggregate paths. A given navigation path included in the particular aggregate path may correspond to a possible user traversal from a first to a second online content source.

Abstract: A facility for determining article influence and author authority based upon cites of the author's articles by other authors is described. Authors post new articles to their blog covering one or more memes, which describe the content of the article. The facility determines other web pages that share the same memes as the articles to form a context set, and then identifies those authors, called stakeholders, that commonly cite posts from web pages within the context set. Stakeholders are those with some knowledge about a particular topic that also write articles on the topic. Articles cited by stakeholders are considered more influential than those that are not cited, and a frequently cited author will have more authority for a given meme than one who is largely ignored, as indicated by receiving few article citations.

Abstract: A method and system for displaying interest space user communities. A method may include detecting a request to access a given online content source, where the request is generated on behalf of a given user, where the given online content source is one of a number of online content sources included within an interest space, and where the interest space is identified dependent upon indications of user navigation activity among the online content sources. The method may further include displaying to the given user a representation of the interest space in response to detecting the request, where the representation includes respective indications of at least a subset of the content sources included within the interest space, and for a given content source within the subset, displaying to the given user respective indications of users on whose behalf a respective previously-generated request to access the given content source has been detected.

Abstract: A method and system for scaling navigation path weights among online content sources. A method may include determining a first probability of users traversing a first navigation path from a first to a second online content source, dependent upon a ratio of traversals of the first navigation path and traversals of all navigation paths to the second online content source. The method may also include determining a second probability of users traversing navigation paths from the first online content source to any of the online content sources, dependent upon a ratio of the plurality of online content sources to which navigation paths from the first online content source exist and a total number of the plurality of online content sources. The method may further include generating from the probabilities a scaling factor indicative of a strength of the first navigation path relative to other navigation paths among the online content sources.

Abstract: A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.

Abstract: A system, method and computer-readable medium for request routing. A client request processing a resource identifier for requested content transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat with the content delivery network service provider's network until a DNS server resolves a DNS query from the client computing device.
