Systems and methods of evaluating information via a computer network are provided. A content group can be identified, and each item of the content group can be associated with a vector indicating at least one user interest category of users exposed to the item. The vectors of each item can be evaluated to generate a first nearest neighbor list of each item of the content group. The nearest neighbor list of a first item can be compared with the nearest neighbor list of a second item. Based on a result of the comparison, the first and second items can be associated in a cluster.

Method and system for evaluating content via a computer network

Techniques are disclosed that enable users to access and use digital mapping systems with constrained-resource services and/or mobile devices (e.g., cell phones and PDAs). In particular, latency of a mapping application on high-latency and low-throughput networks is minimized. One embodiment utilizes volatile and non-volatile storage of the mobile device to cache pre-computed map images (e.g., map tiles). An asynchronous cache can be used to prevent delays caused by potentially slow non-volatile storage. Meta-data about each map image and usage patterns can be stored and used by the cache to optimize hit rates.
