Task: Class Definition Understanding (ontology: Legal/LKIF_Core_Ontology)

Which of the following definitions best describes 'Atom'?

A. An the concept is something that is excluded from a general statement or does not follow a rule. In LKIF rules, an the concept is a rule which has an the concept relation to another rule (cf. Deliverable 1.1)
B. A the concept is a proposition (about something) which is (commonly) agreed upon to hold as true: it has some backing in evidence
C. An the concept is a predictive belief held on purely logical grounds, i.e. not based on direct external evidence, like an observation or a statement by another agent. It is also often characterized as a "belief about the future", but this isn't very helpful since one may also hold expectations about the (yet unknown) past. The theory of evolution is for instance a fertile ground for predictions about the existence of past species, and therefore at the same a predictor of future observations.
D. An the concept is the most basic (undivisible) part of an LKIF rule (cf. Deliverable 1.1)

Answer: An the concept is the most basic (undivisible) part of an LKIF rule (cf. Deliverable 1.1)
