…grasping the meaning, to occupy the right place…
Conceptual system• “structured set of concepts established
according to the relations between them, each concept being determined by its position in the set”
which characteristics – show their similarities and delimitations – are essential to the evaluation of the
connections supporting their relations – reveal gaps and inadequacies
![Page 8: Do conceptual systems improve concepts effectiveness? Joint UNECE/Eurostat/OECD Work Session on Statistical Metadata (METIS) Lisbon, 11– 13 March, 2009.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649f345503460f94c518dc/html5/thumbnails/8.jpg)
…grasping the meaning, to occupy the right place…
Concepts do not exist as isolated units of knowledge,
but always in relation to others
Hierarchic Relations
• Generic• Partitive
Associative Relations
![Page 9: Do conceptual systems improve concepts effectiveness? Joint UNECE/Eurostat/OECD Work Session on Statistical Metadata (METIS) Lisbon, 11– 13 March, 2009.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649f345503460f94c518dc/html5/thumbnails/9.jpg)
Essential conditions to build concept systems
• exhaustive understanding of the conceptualization that structures knowledge
• objectives and expectations of real and potential users
• changes, evolution and expansion that will inevitably occur
…tying designations and definitions
to their respective concepts!
![Page 10: Do conceptual systems improve concepts effectiveness? Joint UNECE/Eurostat/OECD Work Session on Statistical Metadata (METIS) Lisbon, 11– 13 March, 2009.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649f345503460f94c518dc/html5/thumbnails/10.jpg)
…tying designations and definitions
to their respective concepts!Stages to be accomplished
• gathering of unstructured concepts
• consulting of sources of information
• the allocation of the concepts within the concept system
• the formulation of the definitions and the designations for each one.

…tying designations and definitions to their
respective concepts!• concepts selection• terms attribution • definitions formulation

How far leads the path?
Convergenceis of vital importance for users in general:
ensures consistency reduces ambiguity avoids misunderstandings
