2. A WEEK ON FOURSQUARE (WSJ)
www.densitydesign.org
To learn about where people go and what
they do on Foursquare, Digits collected
every check-in on the service for a week
earlier this year (starting at noon Eastern
on Friday, Jan. 21 until noon on Friday Jan.
28), via the Foursquare “firehose” aiming
to see where people checked in around
New York City and San Francisco over
the course of the week.
New York City and San Francisco were
among the first cities where people start-
ed using Foursquare, and the company’s
founders say it’s because the service spread
first among their own friends. Through geolocated check-ins’ and official categorization of Foursquare’s venues analysis,
two kind of data were compared aiming to
highlights common elements and differences who caracterize:
- activities in both territories (New York
City and San Francisco Bay area)
- habits and preferences of genders

14. URBAGRAMS
www.densitydesign.org
A spatial analysis of the aggregate activity
generated by such networks can show us
how social activity in a city is distributed,
revealing fine-grained spatial patterns
evident in the social life of cities.
Large-scale data from one such network
is analysed across three cities in order to
produce an inter-urban analysis. Hubs are
identified from activity distributions, and
measures of polycentricity, fragmentation and centralisation are examined with
respect to levels of social interaction. Spatial clustering tendencies are analysed to
determine the characteristic logics of agglomeration in urban social activity.
These comparative measures are used to
discuss the spatial structure of the three
cities in question. ‘Networked urbanism’
(Graham and Marvin, 2001a) has contained the promise that “the city itself is
turning into a constellation of computers”
(Batty, 1997) for over a decade now.

24. LIVEHOODS
www.densitydesign.org
Unlike the boundaries of traditional
municipal organizational units such as
neighborhoods, which do not always
reflect the character of life in these areas, the Livehoods’ clusters,are representations of the dynamic areas that
comprise the city. The data comes from
two sources. Approximately 11 million
foursquare check-ins from the dataset
of Chen et al. (2011) were combined with
a dataset of 7 million checkins that were
downloaded between June and Decem-
ber of 2011. Foursquare check-ins are
by default not publicly visible, however
users may elect to share their check-ins
publicly on social networks such as Twitter. These 18 million check-ins were all
collected from the Twitter public timeline, then were aligned with venue information from the foursquare API. One
of the main contributions is the design
of an affinity matrix between check-in
venues that effectively blends spatial
affinity and social affinity.

36. THE EMERGENT URBAN IMAGINARIES OF GEOSOCIAL MEDIA
www.densitydesign.org
Geosocial databases inhabit the virtual space in which geosocial media are
produced, and the information that they
contain is both archival and generative
meaning that not only does it provide historical context to a place, but it also gives
access to the contemporary pulse of the
ways that geosocial users perceive, experience and interact in places.
These data can be assembled to speak to
the imaginaries of sub-city scale communities blendind urban place-frames
and the geoweb to show how we per-
ceive and understand urban imaginaries as well as how the geoweb is an evermore integral element of daily life.
Imaginaries are not simply passive representations of sociocultural reality, but are
instead active elements in the structuring
of individual social, cultural and spatial
practice. The imaginaries would be sociospatial meaning that data generated by
individuals about space via Foursquare
would tend to broadcast personal perceptions about how spaces are used
and/or experienced.

50. ESTIMATING PEOPLE PERCEPTION OF INTIMACY
www.densitydesign.org
How does the intimacy relate to privacy?
The main scope of the research is to estimate people intimacy to detect when information about the users’ context can be
collected and shared in order to develop
applications that automatically control
how events and notifications to the users
(receiving a message, a call, an email, a request of approval etc.) are handled by his/
her smartphone or other devices in the
environment, for example assuming that
when the user is intimate the alerts shall
be less intrusive. Analizing raw data of
“Mobile Data Challenge“ collected from 38
selected participants using smartphones
in their daily life and use and elaborating
informations using an algorithm, the researchers derived the users’ level of intimacy in particular places and intervals
of time. The research uses an “Intimacy
Estimation Algorithm” that compute data
from the devices.
51. ESTIMATING PEOPLE PERCEPTION OF INTIMACY
www.densitydesign.org
For the “observers” category:
For the “safe-place” category:
BLUETOOTH --> number of devices
around the user can reveal the number of
people opbserving him;
CHARGING STATUS --> if the phone is
charging it can indicate that the user is
currently in a trusted place;
RING STATUS --> representing the willingness of the user to share the events of the
device with other;
RING STATUS --> is related to “how much”
the user wants to be disturbed by external events;
OUTGOING CALLS --> the duration of a
call made by the user and the relation with
the called person can give a hint about
how the user feels about speaking on
the phone at that moment;
INDOOR/OUTDOOR --> there is a high
probability that if the user is outdoor, he
may not be in a safe place.
OUTGOING SMS --> if a user is exchanging many SMS with a family member or a
friend it may indicate that is in company of
people that are not supposed to know
the content of the conversation;

57. FAR FROM THE EYES, CLOSE ON THE WEB
www.densitydesign.org
Analising a large dataset of anonymised
snapshot of Tuenti’s friendship connections, that includes about 9.8 million
registered users, more than 580 million
friendship links, about 500 million interactions during a 3 month period and the
user’s the self-reported city residence, this
research aims to study how social interactions is related to users’ geographic locations. While spatial prooximity
greatly affects how users establish their
connections on online platforms, the researchers found that social interactions
are only weakly affected by distance: this
suggest that once social connection are
established other factors may influence
how users send messages to their friends.
On the other hand, more active users tend
to preferentially interact over short-range
connections.
This observation is crucial for architectures that optimise distributed storage
of data related to online social platforms based on users’ geographic locations. Similarly, it is important for system
that exploit geographic locality of interest
to serve content items requested through
online social network services. The findings also likely to help other domains
such as link predition, tie strengh interference and user profiling: the observed
spatiual patterns can me also included in
security mechanism to detect malicious
and spam accounts.
58. FAR FROM THE EYES, CLOSE ON THE WEB
www.densitydesign.org
Geographi properties:
Interaction analysis:
Analizing the spatial properties of the
Tuenti social network, may be assumed
that users tend to preferentially connect
to closer users (as found in many other
online social network).
About 60% of social links between users are at a distance of 10km or less,
while only 10% of all distances between
users are below 100 km.
There a re two process taking place. One
process, strongly affected by geographic
distance, influences how users connect
to each other, i.e. their frienship links; another process impacts the level of interaction among connected users and appears unrelated to spatial proximity.
