Abstract:
This paper describes the work done within the Food and
Agriculture Organization of the United Nations (FAO) on providing an
ontology-based navigation for the Food, Nutrition and Agriculture
(FNA) Journal. The aim of the revised navigation was to provide more
efficient and effective browsing of the Food and Nutrition Publications
using a knowledge model to guide the user with concepts and
relationships relevant to a specific subject area. With this approach, data
from two different bibliographical databases was merged, unified and
presented to the user with improved services. A preliminary metadata
merge was needed to combine all the information into one system in
order to produce a metadata-ontology. Resource Description
Framework Schema (RDFS) was chosen to exploit semantic
relationships, e.g. the possibilities of browsing the data in different
ways (by keywords, categories, authors, etc.), and the creation of a
multilingual concept-based advanced search.
