A Mobile Semantic Web:  CMU's testbed for mobile apps built on the Semantic Web.  "MyCampus consists of several task-specific agents that automatically capture contextual information. Each MyCampus user has a database, called a "Semantic eWallet," which is a repository for users' personal information, such as class schedules, list of friends and classmates, and lifestyle and event preferences. Location data is generated using Pango's WiFi access-point triangulation. All the data is marked with Semantic metadata so that MyCampus agents can make use of it. User's can set access privileges to allow certain people to know where they are at any given moment, or what their schedule for the upcoming week is.

One of the most popular applications is the “restaurant concierge” agent, which recommends places based on a user's dining tastes, schedule, location, and weather conditions. If there's a storm brewing, the concierge will recommend a place that doesn't require stepping outside, and if the user has a study group meeting in 30 minutes, it'll suggest a fast food joint within a block or two.

Recently, a group of students at CMU developed an application for MyCampus called InfoBridge, which lets users post and read "virtual posters" about upcoming events. For example, say a user has indicated that she likes track and field events. She’ll be notified about events as soon as another person makes a virtual poster about it, unless she’s sitting in class. If that’s the case, she won’t be notified until class is over. If she wants to attend the event, she clicks on a link and, because the data has been tagged with Semantic Web metadata, it’ll be added it to her calendar. If there’s a scheduling conflict, it’ll notify her and present her with options. All this data exchange is done with agents -- no human screen scraping."  Seems potentially useful for GIS info in remote data-gathering projects also, to notify and sync info that's relevant by location or type.  8:02:47 AM  permalink
