Introduction to MUGGES

Mobile UserGenerated Geo Services

Mobile services are directly accessed, created,

and launched from mobile devices

UserGenerated users create content and type

of services

Geo Services always connected to a location

MUGGES objectives

Beyond usergenerated contents

Users act as consumer, producer, and provider

From their mobile devices

Super

Prosumer

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

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

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

MUGGES Location

Combination of location attributes

Physical (coordinates [43.604, 1.443])

Symbolic (“Toulouse”, “Room 312”)

Semantic (“next to the church”)

Unique location

Benefits

Better search capabilities

Mugglets in child show up in parent

Different ontologies cover different types of locations

(e.g. touristic places)

Reasoning to add attributes

Missing coordinates taken from parent location

Closeness relation based on sibling feature
