Our vision

Massive amounts of data and other information are in principle available to us almost anywhere and instantly, but most of them are in practice hidden and inaccessible: They are not turned into actual knowledge but represent what we call Knowledge in the Dark or short: Dark Knowledge (Jeschke et al. 2018). Untapping Dark Knowledge is a huge challenge.

Hi-Knowledge tackles this challenge. It is a novel online tool that structures information in a unique way, thus making it accessible to science and society. It will allow scientists to perform instantaneous synthetic analyses (meta-analyses sensu lato) tailored to their specific needs. Currently, meta-analyses and other syntheses of research data are either unavailable for a given topic or are outdated shortly after publication.

Hi-Knowledge is also for policy makers, managers, teachers and students, as it uniquely structures available scientific information in a readily accessible way. For instance, it will provide a continuously updated overview of scientific hypotheses and their degree of empirical support. Such knowledge is vital for science and society.

Cover of Invasion Biology – Hypotheses and Evidence

The initial phase of the project focuses on invasion hypotheses and accompanies the book Invasion Biology – Hypotheses and Evidence (Jeschke & Heger, eds, 2018; CABI, Wallingford, UK).

Launch visualisation

In the future, Hi-Knowledge will become the unique web portal described here – this is our vision, at least.
