The definition of a formal ontological framework aimed at semantic interoperability: the case for fisheries domain:  The definition of a formal ontological framework aimed at semantic interoperability: the case for fisheries domain Aldo Gangemi1, Frehiwot Fisseha2, Johannes Keizer2, Marc Taconet4, Ian Pettman3, Domenico M.

RT are transformed into axioms; e.g.: PARTICIPANT(i1,i2), provided that the topmost parents of c1(i1) and c2(i2) are related by PARTICIPANT in the core ontology? Topic trees into (preliminary) topic spaces Conceptual templates:  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 The APO schema:  The APO schema Use of APO:  Use of APO It resulted useful in several domains: clinical guidelines (planning vs. process knowledge) fishery (management vs. intervention knowledge) banking regulations (legal vs. world knowledge) possibly extendable to the general problem of control knowledge In the third lecture some examples from the banking domain will be given Warn the mereotopological constraints when applying it! The APO schema modified for clinical conditions:  The APO schema modified for clinical conditions APO applied to transactions:  APO applied to transactions OCT: the OntoClean Top-level:  OCT: the OntoClean Top-level A core ontology for aquaculture:  A core ontology for aquaculture An excerpt from the ontology:  An excerpt from the ontology The concept fishing technique is formalized in a description logic as follows: (defconcept Fishing-Technique :annotations ((DOCUMENTATION "FIGIS: A fishing technique describes the set of equipment used for the capture of a target species together with any associated fishing practices.")) :is (:and Technique (:some INVOLVES Gear) (:some METHOD-OF Fishery) (:some PART Handling-Mode))) FOS development (3):  FOS development (3) Producing or reusing glosses (informal descriptions) Building and refining library architecture Choosing integration architecture (mediation or merging) Applying integration, building and active cataloguing procedures Building (or reusing) query interface and wrappers to source dbs Fisheries merged information access:  Fisheries merged information access A user query is submitted to an interface connected to the Fishery Ontology Server. 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.
