The Fukushima Nuclear Disaster in Social Media


Social Media and the Market

Geospatial Intelligence @ Mason 5.2013© George Mason University© Dr. Arie Coritoru,


Motivation: The Proliferation of Social Media

• Twitter: 400 million accounts (140 million active users) (9th most populous country in the world – above Japan)

• Facebook: 1 billion users (the world’s 3rd most populous country), and 6 billion photos uploaded monthly

• flickr: 6 billion photos (3,000 photos uploaded every minute)

• QQ has 800 million accounts


Motivation: User-Generated Digital Content


Social Media and Intelligence


Reporting Events


Building Communities


A New Communication Tool


A New Battlefield


Social Media Contant and

GeoSocial Analysis


Geolocation Information


Social Media Content: The Message


Social Media Content: Social Networks


A GeoSocial Approach

GeoSocial data mining:

A unique combination of geospatial, social network, and content analysis, to understand the human landscape and gain situational awareness.


A GeoSocial Approach: An Example


Opportunities and Challenges


Test Case: Mineral, VA Earthquake (Summer ‘11)


Event Responses in Twitterdom


Impact Area Assessment: People as Sensors


Test Case: Occupy Brooklyn Bridge (Winter ‘11)


Validation Test Case: OWS Day of Action (11/17/11)


GeoSocial Clustering (Test case: Occupy Wall Street, 11/17/11)

Identifying keywords:

Understanding what are the defining

keywords for evolving events.


Social Network Analysis


The Interplay of Cyber and PhysicalHybrid

Communities:

Where cyber meets spatial


Geography Redefined: Case Study Syria



A new map of Syria as a polycentric state.


Test Case: Boston Marathon Bombing


Test Case: Boston Marathon Bombing (cont.)


Test Case: Hurricane Sandy


GeoSocial Gauge: A Sample Architecture


GeoSocial Gauge: Front End


Outlook

• Authoritative vs. open-source: a changing balance

• Social Media: Opportunities and challenges

• From post-event response to predictive analysis

• GeoSocial Analysis: A new type of analysis for a new type of data and events

• Validation

• Improving signal-to-noise
