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
