The document describes ReVeaLD, a user-driven domain specific search platform for biomedical research. ReVeaLD allows users to interactively search biomedical literature and linked data. It supports natural language queries, performs semantic query transformation using templates, and retrieves results from linked data sources. ReVeaLD aims to enable knowledge discovery and hypothesis generation for researchers.
