Abstract: In one example, a data package created by a particular wireless mobile device, and comprising metrics collected by the wireless mobile device, is retrieved. The metrics concern performance of the wireless mobile device in a wireless communication network, and are transformed into measures that enable derivation of a key performance indicator concerning the performance of the wireless mobile device. An enriched measure is generated by processing the measures based on correlations of wireless mobile device events in a time sequence, and the enriched measure is transformed into a KPI that is specific to the performance of the wireless mobile device. The KPI of the wireless mobile device is compared to a KPI of the population of wireless mobile devices, and results of the comparison of KPIs serve as a basis to resolve a problem regarding operation of the wireless mobile device.

Abstract: Electronic messages, such as emails, often ask questions, ask that a task be done, or assign a task. The responsive messages often forget to answer the questions and the responders often forget to calendar tasks. Advances in natural language processing provide computers the ability to notice the questions and task requests/assignments. Automated analysis of the messages can detect and highlight questions, can provide for draft responses addressing every question, and can provide for getting tasks calendared.

Abstract: Distributed computing system functionality is enhanced. Transmission of data changes may be incremental, thus reducing bandwidth usage and latency. Data changes may be propagated over geographic distances in an outward-only manner from a central data store to one or more servers or other remote nodes, using proactive updates as opposed to making cache updates only in reaction to cache misses. Cache expiration and eviction may be reduced or avoided as mechanisms for determining when cached data is modified. A central computing environment may proactively push incremental data entity changes to place them in remote data stores. Remote nodes proactively check their remote data store, find changes, pull respective selected changes into their remote node caches, and provide current data in response to service requests. Data may be owned by particular tenants. Data pulls may be limited to data in selected categories, data of recently active tenants, or both.
