Computer-implemented systems and methods for synthesis of concept definitions and concept relationships from a domain of data, utilizing different semantic processing protocols such as formal concept analysis and faceted classification synthesis from existing domain concepts that have a confidence gradient built into them. A cognitive or an input agent provides an input of an active concept which is matched against existing domain concepts. The resultant pool of relevant domain concepts is then used to derive virtual concept definitions using a semantic processing protocol. The derivation is then overlaid with a concept of relative proximity of an attribute from another within an attribute set. An additional layer of coherence is given by the relative proximity measure. The end result is a pool of related virtual concept definitions in a tree structure.

L'invention porte sur des systèmes et des procédés informatisés qui permettent de synthétiser des définitions de concepts et des relations entre concepts issus d'un domaine de données, par la mise en oeuvre de différents protocoles de traitement sémantique, comme l'analyse formelle de concepts et la synthèse de classification à facettes, sur des concepts de domaines existants auxquels est intégré un gradient de confiance. Selon l'invention, un agent cognitif ou un agent d'entrée fournit une entrée de concept actif qui est comparée à des concepts de domaines existants. On utilise alors le groupe de concepts de domaines pertinents obtenu pour dériver des définitions de concept virtuelles à l'aide d'un protocole de traitement sémantique. On superpose ensuite à la dérivation un concept de proximité relative d'un attribut par rapport à un autre attribut appartenant à un ensemble d'attributs. La mesure de la proximité relative fournit une couche de cohérence supplémentaire. On obtient comme résultat final un ensemble de définitions de concepts virtuels liées en une structure arborescente.
