Gangemi, Fisseha, Keizer, Taconet, Pettman, Pisanelli: A Merged Fishery Ontology for Semantic Interoperability Conceptual templates Conceptual templates are relevant parts of ontologies that describe the core concepts and relations of a domain (core ontologies) Ex. APO, BFQF, etc. They can be often discovered from: database schemata, forms, elicited know-how analysis of systematic polysemy

Interface and Server communicate with a Topic-Based Fishery Information Browser. The browser can either interrogate the source systems, or perform own searches to document corpora. The Server can directly provide information on fishery conceptual structures, terminology, and scope notes.
