The document describes a hybrid and semantic location management system (HS-LMS) for mobile user-generated geo services (MUGGES). The HS-LMS allows for a consistent location concept between micro-applications called "mugglets" by mapping different location aspects like coordinates, symbols, and semantics. It also enables reasoning between related locations through ontologies describing political, administrative, and geographic relationships. The system aims to provide better search capabilities and attribute information for mugglets through relationships defined in the location ontologies.

Introduction to MUGGES
Mobile UserGenerated Geo Services
 Mobile services are directly accessed, created,
and launched from mobile devices
 UserGenerated users create content and type
of services
 Geo Services always connected to a location

MUGGES objectives
Beyond usergenerated contents
 Users act as consumer, producer, and provider
 From their mobile devices
Consumer Producer
Super
Prosumer
Provider Mobile

5. Objectives Architecture HS-LMS Conclusion
Mugglets
MUGGES micro-applications
 Sharply focused applications
 Instantaneously available
 Short-term, i.e. up-to-date information
 Every user is potential creator and
provider (“prosumer”)
 From mobile to mobile
 Location-based

6. Objectives Architecture HS-LMS Conclusion
Use Case
 Jack comes to the Toulouse Space
Show
 Long and interesting day
 A “muggesNote” indicates a good
restaurant close to the conference
center
 Jack meets colleagues from the
talks and has a good dinner
 Creates muggesNotes
recommending the steak

8. Objectives Architecture HS-LMS Conclusion
Location Problem
 Location has many facets
 “Toulouse, France”, “Room 312”
 “Next to the church”
 “Latitude 43.604, longitude 1.443”
 Several location mechanisms
 GPS / Galileo
 Cell tower or Wi-Fi network ids
 Text input

9. Objectives Architecture HS-LMS Conclusion
MUGGES Location
 Combination of location attributes
 Physical (coordinates [43.604, 1.443])
 Symbolic (“Toulouse”, “Room 312”)
 Semantic (“next to the church”)
 Unique location
