criterionoften

Criterionoften is a coined term used to describe a family of decision criteria that emphasize the frequency with which criteria appear or are satisfied across tasks. In this notion, a criterionoften assigns greater influence to criteria that recur or remain relevant across multiple situations, rather than treating all criteria as equally important. It is often discussed in the context of multi-criteria decision analysis and data-driven optimization as a way to reflect commonality across cases.

Origin and usage: The term has appeared primarily in theoretical discussions, workshops, and exploratory writings rather than formal standards. It lacks a single, widely accepted definition, and practitioners may describe the idea using related phrases such as frequency-weighted criteria or occurrence-based weighting. As a result, the concept is typically treated as a heuristic or modeling approach rather than a fixed methodology.

Definition and formalization: A simple formalization defines, for each criterion c in a set C, a frequency f(c) representing how often c is considered relevant across tasks. A weight w(c) is then assigned proportional to f(c), so w(c) = f(c) / sum over c in C of f(c). The criterionoften-augmented score for an option is the weighted sum of unit criterion scores. This approach favors criteria that are commonly observed, balancing breadth of relevance with task-specific signals.

Applications and limitations: Criterionoften can be useful in settings with large criterion spaces and recurring patterns, such as feature selection, recommender systems, and adaptive planning. However, overemphasis on frequent criteria can overlook rare but critical factors, so it is common to combine frequency-based weights with domain knowledge or safeguards to ensure important minority criteria are not neglected.
