"Knowledge Modeling and Discovery: Understanding Risks, Outcomes and the Ever Changing Nature of Complex Systems" Presenter: Danielle Forsyth, CEO & Co-Founder, Thetus Corporation. 1.5 - 2.0 hours. Abstract:

Advances in collection technology have fueled an unprecedented increase in the amount of data generated in 
earth sciences research. The majority of critical information is never located and leveraged because traditional 
information management systems are not designed to cope with massive amounts of data pouring in from 
satellites and sensors as well data residing in silos—structured using proprietary, inaccessible metadata formats.  
Designed to enable users to model, discover, track, and evolve information from within disparate stores of 
complex, multi-layered data, Thetus Publisher provides the essential component to complement traditional 
information management systems and enable data-rich, knowledge poor earth sciences organizations to realize
the full potential of their most valuable assets: knowledge and knowledge workers. In the earth sciences, 
organizations must process and analyze massive amounts of complex, multi-source, multi-format data in order 
to analyze, hypothesize, predict, and act. Semantically-based knowledge modeling and discovery systems allow 
organizations to integrate, automate, and enhance spatial and non-spatial data within a dynamically-evolving 
knowledge base, enabling users to search, relate, annotate, and share information across multiple communities 
of interest.
