Evaluating Outbreak-Detection Methods Using Simulations: Volume Under the Time-ROC Surface
Content Type: Abstract
There are many proposed methods of identifying outbreaks of disease in surveillance data. However, there is little agreement about appropriate ways to choose amongst them. One common basis for comparison is simulating outbreaks and adding the simu… read more… ways to choose amongst them.

Semantic Approach to Text Understanding of Chief Complaints Data
Content Type: Abstract
Chief complaints are often represented textually and as a mixture of complex and context-dependant lexical symbols with little formal sentence structure. Although human experts usually comprehend this information in its right context intuitively and… read more… to process- ing free form text information such as chief com- plaints using formal knowledge representation and … challenge.

An Enterprise Information Integration (EII) Approach for a Syndromic Surveillance System
Content Type: Abstract
A comprehensive definition of a syndrome is composed of direct (911 calls, emergency departments, primary care providers, sensor, veterinary, agricultural and animal data) and indirect evidence (data from schools, drug stores, weather etc.).… read more… BACKGROUND A comprehensive definition of a syndrome is com- posed of direct (911 calls, emergency departments, … 2003.

Online Temporal Clustering for Outbreak Detection
Content Type: Abstract
We hypothesize that epidemics around their onset tend to affect primarily a well-defined subgroup of the overall population that is for some reason particularly susceptible. While the vulnerable cohort is often well described for… read more… being studied. REFERENCES [1] Singliar, T. and D. Dash. COD: Online Temporal Clustering for Outbreak Detection.

What Is the True Shape of a Disease Cluster? The Multi-Objective Genetic Scan
Content Type: Abstract
Irregularly shaped spatial disease clusters occur commonly in epidemiological studies, but their geographic delineation is poorly defined. Most current spatial scan software usually displays only one of the many possible cluster solutions with… read more… de- grees of penalization parameters imposed to the free- dom of shape [1].
