relewantnoci

Relewantnoci is a theoretical metric used in information theory and cognitive science to describe the perceived value of information when selecting what to present to a user. It represents a balance between relevance to the user’s goals, novelty, and cognitive cost.

The term is a neologism formed to convey the idea of combining relevance with novelty and cognitive considerations. It is used mainly in academic discussions about content selection, curation, and AI-assisted information presentation, and does not refer to a single universally standardized measure.

In practice, relewantnoci is defined as a weighted combination of normalized components: Rel (relevance to the user context), Nov (novelty relative to user history), and Cog (estimated cognitive load). A typical form is U = α*Rel + β*Nov - γ*Cog, with α, β, γ > 0 and α+β+γ = 1. Higher U indicates higher information value for presentation or recommendation.

Applications of relewantnoci appear in recommender systems, news and article curation, educational content sequencing, and editorial decision-making. Researchers study how to estimate Rel and Nov via user models, implicit feedback, and content analysis, aiming to maximize user engagement while maintaining clarity and learning efficiency.

Criticism and limitations of the concept focus on its heuristic nature and dependence on chosen weights and measurement methods. Measuring novelty can be highly context-dependent, and optimizing for novelty can inadvertently reduce relevance or increase cognitive burden. Consequently, practical utility requires careful calibration, transparency about assumptions, and ongoing validation across domains.
