óvissa

Óvissa is a hypothetical term used in information science and knowledge representation to denote a class of statements or data points that are uncertain or lack robust supporting evidence. The concept is intended to help distinguish between well-supported information and probabilistic or disputed claims within knowledge bases, wikis, and research corpora.

Etymology and usage: The name combines a negating prefix with a notion of certainty, reflecting a general idea of negation of assuredness. Although inspired by European-language roots, the term is not part of an official, standardized taxonomy and remains informal in most contexts. In practice, items labeled as óvissa are typically flagged with a low confidence level and may require corroboration, primary sources, or expert review before being treated as established facts.

Classification and criteria: An item might be designated óvissa if it depends on a single source, involves speculative inference, relies on outdated information, or presents contradictory accounts. The exact criteria can vary between repositories or projects, often accompanying the label with notes such as “unverified,” “speculative,” or “in need of corroboration.”

Impact and critique: Supporters argue that óvissa helps prevent overclaiming and increases transparency about evidence gaps. Critics contend that without standardized guidelines, the term can introduce ambiguity or be misused as a catch-all for uncertain information.
