Development of Multilingual Domain Ontologies Fishery Ontology
• The goal Making information interchangeable between
ASFA, FIGIS, OneFish and Agrovoc
• The approach Creating an ontology, integrating or mapping
the 3 different systems + Agrovoc Linking of the Ontology through wrappers to
the different Information Systems

1) Form versus meaning: a) Traditional Search
FAOBIB results
Using a free text search, the system retrieves all records containing the string “vessel” including records not pertinent to the user’s intended meaning of the term
Using a keyword search, the system retrieves 0 results as the thesaurus used in this portal does not use vessel as a keyword

1) Form versus meaning: b) Concept Search
In a concept based search the system retrieves all meanings represented by the term vessel.
For example:- vessel can refer to the concept blood vessel- vessel can also be interpreted as ship
