How Fuzzy Association Rule Mining and Twitter Can Save Lives

How Fuzzy Association Rule Mining and Twitter Can Save Lives

As the U.S. recovers from one of the worst cold and flu seasons in recent years, incidents of the avian flu are appearing across China, and other infectious diseases continue to spread across most regions of the world. Outbreaks like these can have immediate and negative impacts on our communities and put a strain on our health and emergency response resources.

Two recent innovations by the Johns Hopkins University (JHU) are using more sophisticated data modeling and social media technologies to improve the tracking and predicting of infectious diseases.

  • A team of scientists from the JHU Applied Physics Laboratory has developed a way of accurately predicting outbreaks several weeks before they occur using a new data modeling tool (PRISM—Predicting Infectious Disease Scalable Model). PRISM uses Fuzzy Association Rule Mining (FARM) to extract relationships between multiple variables in a data set, such as clinical, meteorological, climatic, and socio-political data. The model can help decision-makers assess the future risk of a disease outbreak occurring in a specific area at a specific time.
  • Social media has been used to track information about the spread of certain diseases for years. New tweet screening methods using sophisticated statistical modeling based on human language processing technologies developed by researchers at JHU are improving on this capability. They can filter out online chatter not linked to the actual disease to achieve more accurate results that more closely match government disease data and in much less time (CDC data can take up to two weeks to publish while social media is near real time).  

These and other innovations enable communities to make informed decisions about limited resources and quickly anticipate the needs for outreach and health services to decrease the impact of future outbreaks.

Boosting the Mission: Developing Acquisition Requirements Guidance

Boosting the Mission: Developing Acquisition Requirements Guidance

To keep up with the fast pace of change in the field of Government acquisitions, Department of Homeland Security (DHS) components are developing their own acquisition requirements (AR) policies. However, without specific timeframes to finalize these policies, DHS agencies often lack guidance on how to develop ARs. Among DHS agencies, the U.S. Coast Guard is leading the way with their own formal policy to describe this process. To compliment the U.S. Coast Guard’s policy, DHS created the Joint Requirements Integration and Management System (JRIMS) to offer direction for agencies—to review, validate, and suggest solutions for capability gaps and requirements.

Think, Key, Speak: Purposeful Communications

I spent the early years of my career in the United States Navy as a Naval Flight Officer on the E-2C Hawkeye, the Navy’s aircraft carrier-based Airborne Early Warning and Command and Control platform. The various missions of the aircraft demand that aircrew monitor up to ten radio frequencies, and actively speak on three or four of those, at any given moment in flight.

How Can Communities Ready Themselves for a Major Power Grid Event?

How Can Communities Ready Themselves for a Major Power Grid Event?

Communities are often the foundation for an expedited recovery following major events. But how can communities strengthen their response to, for example, a major cyber-attack or natural event, such as an Electronic Magnetic Pulse solar flare? A United States electrical grid failure could destroy a number of the nation’s high voltage transformers causing widespread outages for several weeks, even months. A public health emergency could quickly ensue particularly among the vulnerable as the ripple effects cause significant societal disruption. The Federal Emergency Management Agency’s (FEMA) strategic plan encourages and empowers communities to prepare for the inevitable impacts of future disasters. How can communities prime for major events?

Confessions of a Chief Strategy Officer

Confessions of a Chief Strategy Officer

I’ll admit it, I was a little smug. After more than 20 years in the consulting business helping clients develop, implement, and integrate their strategies, I thought… “how hard could it be to do the same things for my own company – a company of consultants?” I had the commitment of my leadership, a group of talented people, and a plan and resources to grow the company. We had energy and we had a great process and tools to successful. What could go wrong?
