What is the technology behind this?

Jiglu is powered by the Jiglu Dynamic Discovery Engine. This allows large bodies of dynamic content to be analysed in context and the hidden links between different elements to be exposed.

The system is based on four years of research and refinement, working with e-mail, wiki entries and RSS to better intelligently tag content. While other services provide textual analysis of individual pages, Jiglu Dynamic Discovery analyses how a piece of content fits in with everything else, and in real time.
