The document discusses using urban games and games with a purpose (GWAP) to improve linked data about smart cities. It describes several ongoing LarKC projects that integrate different types of urban data through semantic web technologies. It proposes using GWAP to engage citizens to help assess and correct linked data about urban environments. The vision is that open data, structured data, and data from citizens can be combined with linked data, semantic web, and GWAP to create urban games that both entertain users and collect useful information to support smart cities.

1. Urban Games for Smart Cities
"Vision Workshop" on Smart Cities
Irene Celino – Semantic Web Practice

2. Urban Computing in LarKC
Urban LarKC:
Integration of data about monuments, events and path-finding in
Milano through Linked Data and Open Data
(also extensible to other locations)

Traffic LarKC:
Integration of traffic predictions and path-finding in Milano through
Machine Learning and Semantic Web technologies
in collaboration with Siemens

Local "Mavens" (ongoing work)
Extraction of data from social networks (Twitter, foursquare, etc.) to
identify "experts" of local POIs in Seoul (e.g. restaurants)
JRU with Politecnico, in collaboration with Saltlux and Siemens

3. GWAP per Linked Data Quality
(ongoing work)
Games with a Purpose (GWAP)
game played on a computer that serves some purpose for the
people setting up the game by harnessing human abilities in an
entertaining setting
Data collection
e.g. GWAP used to tag images
Data quality assessment
e.g. GWAP (or sort of) used to correct/update
manually curated datasets
Linked Data are large datasets that contains
information with a varying level of quality
let's use GWAP to improve Linked Data sets
(about urban environments)

4. Vision: 3 converging trends?
open data, Urban Computing e citizens as sensors,
structured data, check-in logging,
Location-based Services
government data, mobile apps
tourism data, social (LBS)
networks, touristic
recommendations
Urban
Games
Linked Data e Games with a Purpose
Semantic Web e Crowdsourcing
collecting data, cleaning
Preliminary contacts with: data, engaging the user,
supporting the user while
entertaining him/her
