2. GACS??
= Global Agriculture Concept Scheme
• To make a common repository of
terminological and conceptual information in
agriculture
• To achieve efficiency of scale by maintaining
core concepts in cooperation
4. Why should all this be interesting? #1
Vocabularies are used in concrete applications
to describe datasets, pieces of data
5. Why should all this be interesting? #2
Both vocabularies and data can be linked ->
more data getting closer to grasp
– E.g. AGROVOC linked to 16, EUROVOC, GEMET,
GeoNames, Wikipedia, LCSH, ...
7. Where are we now?
• First prototype, Alpha 1, internal
• Formed by mapping a core of 10,000 concepts
from each vocabulary
– Info from matched concepts is aggregated – only Only
exact match considered
• Result: ~ 15,000 concepts, ~ 400,000 terms
11. Different in concept granularity
AGROVOC: [animal oil], [animal fats]
NALT: [animal fats and oils]
12. Modelling
• Common names and scientific names are
different things? Or different names for the
same things?
• E.g. Salmo salar, salmo carpio, salmo ferox -
salmon
