poznatok

Poznatok is a term used in theoretical discussions of knowledge representation to denote a minimal, verifiable unit of knowledge that can be shared between agents. In this usage, a poznatok is atomic, meaning it cannot be meaningfully split into smaller truth-claims without losing verifiability, and transferable, so it can be encoded in varying media or protocols. A poznatok should be verifiable independently of its immediate context; its truth value can be checked against evidence, data, or established facts.

The term is derived from Slavic roots related to knowledge, combining a root associated with knowing with a diminutive or nominal suffix. It is commonly contrasted with larger aggregates such as claims, propositions, or knowledge graphs, which may encompass multiple poznatoks.

In practice, a poznatok serves as a building block in educational technology, knowledge graphs, and learning analytics. Each poznatok may represent a discrete fact or skill, such as a definitional statement, a procedural step, or a basic data interpretation. Because a poznatok is designed to be verifiable independent of context, it can be recombined into new sequences for different learning objectives.

The concept emerged in the 2010s within debates on knowledge representation and micro-credentialing. Critics argue that ensuring genuine verifiability across contexts is difficult and that overly fine granularity can overwhelm learners and systems. Proponents see poznatok as a way to formalize learning outcomes and to enable cross-domain interoperability.
