BioNavigation: Selecting optimum paths through biological resources to evaluate ontological navigational queries

Abstract:

In this paper we present the BioNavigation system that allows scientists to express their queries using an ontology representing the conceptual level of scientific classes and labeled relationships. We developed the ESearch algorithm that generates all possible evaluation paths for a given ontological query and ranks them based on source metadata metrics. BioNavigation thus helps the user visualize the resources at a higher ontological level, build queries graphically, and provides valuable guidance on selecting the optimum path through the maze of resources. © Springer-Verlag Berlin Heidelberg 2005.
