Closed World Assumption

What Is Closed World Assumption

In a formal system of logic that is used for the representation of knowledge, the closed-world assumption (often abbreviated as CWA) is the supposition that a statement that is true is also known to be true. Therefore, the inverse of this is true, which is that which cannot currently be verified as being accurate. Raymond Reiter is the author of a logical formalization of this assumption that bears the same name as this assumption. The open-world assumption (OWA), which holds that a lack of knowledge does not automatically entail that something is untrue, is the hypothesis that directly contradicts the closed-world hypothesis. The interpretation of the real semantics of a conceptual statement with the same notations of ideas is determined by the decisions made regarding CWA versus OWA. In most cases, a good formalization of natural language semantics is going to need an explicit revelation of whether the implicit logical underpinnings are based on CWA or OWA. This is because CWA and OWA are two distinct schools of logical thought.
