👉 A pre-reference is a type of reference that has been established in a specific context and serves as a starting point for further information or analysis. It typically involves a set of guidelines, rules, or criteria that are used to determine what is considered "pre-referential" or "prior." In the context of data mining, a pre-reference can be defined as a feature or attribute that has been previously identified and categorized in the dataset, but which has not yet been utilized for further analysis.
