Title
Expressing user profiles for data recharging
Abstract
e are rapidly heading toward a world in which the computing infrastructure will contain bil- lions of devices that are carried or worn by their users as they go through their daily routines. These devices require two key resources to function: power and data. The mobile nature of such devices combined with the economic limitations of size and cost makes it impractical to keep them continually connect- ed to fixed sources of either resource. Mobile devices cope with disconnection from fixed sources of power and data by "caching." For power, devices typically use rechargeable batter- ies; batteries act as a cache of power from the fixed power grid. Likewise, data from the "information grid" (i.e., the Internet) is cached in device-local storage (memory, flash memory, disk, etc.) for use by the applications running on that device. Periodically, a device's batteries must be recharged by con- necting with the fixed power grid. Performing such recharging is easy: the device can be plugged into any electrical outlet that is available; the charge can be interrupted at any time —- the longer it is plugged in, the better the charge gets, until it is fully charged; and most important, the process happens with minimal intervention by the user. Abstract Mobile devices need two basic renewable resources — power and data. Power recharging is easy; data recharging is a much more problematic activity. It requires complex interaction between a user and a collection of data sources. We provide an automatic data recharging capability based on user profiles written in an expressive profile language. A profile identifies relevant information and orders it by its usefulness. In this article, we discuss the issues involved in designing a profile language for data recharging.
