DIRECTIONAL EXPRESSION-BASED SCIENTIFIC INFORMATION KNOWLEDGE MANAGEMENT

The present invention relates to methods, systems and apparatus for capturing, integrating, organizing, navigating and querying large-scale data from high-throughput biological and chemical assay platforms. It provides a highly efficient meta-analysis infrastructure for performing research queries across a large number of studies and experiments from different biological and chemical assays, data types and organisms, as well as systems to build and add to such an infrastructure. In particular, aspects of the invention relate to integrating, organizing, navigating and querying “directional” data, such as gene expression profiles.
