Creating the ontologists of the future
The goal of the Ontology Summit 2010 was to address the current shortage of persons with ontology expertise by developing a strategy for the education of ontologists. To achieve this goal we studied how ontologists are currently trained, the requirements identified by organizations that hire ontologists, and developments that might impact the training of ontologists in the future. We developed ...
متن کاملSNOMED CT's Problem List: Ontologists' and Logicians' Therapy Suggestions
After a critical review of the present architecture of SNOMED CT, addressing both logical and ontological issues, we present a roadmap towards an overall improvement of this terminology. In particular, we recommend the following actions: Upper level categories should be rearranged according to a standard upper level ontology. Meta-class like concepts should be identified and removed from the ta...
متن کاملLeptogenesis from Right-handed Neutrino Decays to Right-handed Leptons
We investigate what would be the consequences for leptogenesis of the existence of a charged SU(2)L singlet scalar δ . If such a scalar particle exists it allows the right-handed neutrinos to couple not only to left-handed lepton and Higgs doublets as in ordinary leptogenesis, but also to a right-handed charged lepton and a δ. This provides a new source of leptogenesis which can be successful i...

متن کاملCharacterization of right-handed and left-handed shapes
Many natural shapes are chiral (or handed). Our hands, for example, have a righthand version and a left-hand version, the two types being mirror images of each other. Molecules are also classi ed according to their chirality, which determines their chemical characteristics. Glucose, for example, is sweet only in one chirality, while it is tasteless in the other. The notion of chirality for two ...
