What viable technologies exist to enable the development of so-called desktop virtual reality (desktop-VR) applications? Specifically, which of these are active and capable of helping us to engineer a multi-user, collaborative, virtual environment (CVE)? An examination of the literature and numerous project websites indicates an array of both overlapping and disparate approaches to this problem...

In a typical Event-Based Surveillance setting, a stream of web documents is continuously monitored for disease reporting. A structured representation of the disease reporting events is extracted from the raw text, and the events are then aggregated to produce signals, which are intended to represent early warnings against potential public health threats.
