The knowledge navigation platform 'Knowlegator' is designed to derive actionable-knowledge from the web content. It comprises of (i) a content acquisition engine that drives the delivery of literature from distributed public repositories, (ii) a workflow of natural-language processing algorithms that deliver semantically indexed sentences as A-boxes to OWL-DL ontologies, and (iii) a drag 'n drop visual query composer that facilitates query navigation over concept hierarchies, instantiated object properties and visualization of data type properties in the ontology. The platform has been deployed in series of life science application scenarios. This talk will showcase 'instantiated' ontologies constructed for knowledge navigation in the domains of lipidomics, disease epidemiology and mutated phosphatases.
