Open-world Assumption
Definitions
D1 [ Arp et al., 2015 ]
- The assumption that we capture knowledge within an ontology or ontology-like resource in an ongoing process as we discover it, so that we can at no stage guarantee that we have discovered complete information — hence no conclusions should be drawn from the fact that a given assertion is not recorded in our system.
In a formal system of logic used for knowledge representation, the open-world assumption is the assumption that the truth value of a statement may be true irrespective of whether or not it is known to be true. It is the opposite of the closed-world assumption, which holds that any statement that is true is also known to be true. (https://en.wikipedia.org/wiki/Open-world_assumption)
