Urban Computing and Location-based Services
Linked Data and Semantic Web
Games with a Purpose and
Crowdsourcing
Urban GamesUrban Games
citizens as sensors, check-in logging, mobile apps
collecting data, cleaning data, engaging the user, supporting the user while entertaining him/her
open/gov data, structured data, social networks,
tourism data and recommendations

UrbanGames - Approach
• Urban Games:• to consume, create and assess the quality of
Smart Cities-related Linked Data
• via a Human Computation approach
• for users in mobility with smart phone devices
• Traditional Human Computation approaches are based on users' domain knowledge…
…while Urban Games are based on and aim at exploiting "on site" users' experience knowledge

LinkedGeoData(OpenStreetMap)
bootstrap of "venues" data
players
game to buy / sell venues with missions
data about venues as missions
GWAP approach to consolidate dataverified / improved data
+ new data
Game purpose: check and correct pre-existing data from LinkedGeoData (OpenStreetMap) + collect missing data

Urbanopoly – how it works
PlanetData - UrbanGames - 2012/05/10 Madrid meeting
home players "visit" venues from the map
players have missions to get venues/money

data validation missions
data addition or correction missions
social incentive
Slide 9 of 12
Urbanopoly – evaluation
• Validation/correction of pre-existing data• Accuracy
• Completeness
• Collection of new data• Accuracy
• Ranking
• "Popularity" of information
• Engagement • Throughput
• Average Lifetime Play
• Usability/playability

Urbanopoly – modelling issue
Ok, we gathered data: now what?
1. Simply publish data like LinkedGeoData
2. Add dataset/linkset description (VoID)
3. Add provenance (PROV-O) and confidence annotations
4. Consider games as sensors data ("human as sensors" reusing SSN)
5. Stress the "data quality" aspect (extending DQM vocabulary)
6. …
