    Abstract: A method and apparatus for determining geographic clusters of geographical content may include computation of a first evaluation metric. The first evaluation metric may be descriptive of a distribution of geo-location points within a cluster of a plurality of geographic clusters. A second evaluation metric may also be computed that is descriptive of coherence of the plurality of geographic clusters. Geo-location points of the geographical content may be clustered based, at least in part on the first and second evaluation metrics.

    Abstract: Software for a content-aggregation website generates a first representation of interests for a geographical location. The representation includes a plurality of entities that are derived from a corpus of documents. Each of the plurality of entities is associated with an expected value that is based on engagement signals from users in the geographical location and that is weighted using a sparse-polarity approach to be discriminative with respect to other entities. Each of the ingested articles is represented by the second representation that associates an aboutness score with each of the plurality of entities. The software uses the first representation, a similarity measure, and a second representation to create rankings of a plurality of ingested articles received. Then the software receives a request for access to the content-aggregation service from a new user from the geographical location and serves the new or infrequent user a content stream based on the rankings.

    Abstract: Methods and apparatus for improving performance of a system including a first computing system are disclosed. In one embodiment, the first computing system receives a request via a network from a client device. The first computing system determines whether a second computing system is available to respond to requests from the first system. The first computing system obtains a response to the request received from the client device based, at least in part, on one or more estimated values maintained by the first computing system according to whether the second computing system is available to respond to requests from the first computing system. The first computing system transmits the response to the client device.
