deléció

Deléció is a term used in information studies and digital humanities to describe the intentional removal of elements from a dataset, document, audio track, or visual content. The purpose is to reduce redundancy, minimize exposure of sensitive information, or improve interpretability and processing efficiency. The coinage is attributed to early-21st-century scholars exploring privacy-preserving analytics and data-centric archiving; the word blends the English verb delete with a Romance-language suffix -ció to form a noun.

Definitions and scope: Deléció encompasses several practice types, including data minimization (selective deletion of personal or nonessential data), content summarization through deletion (pruning extraneous material to yield concise representations), and context-preserving deletion (removing elements while preserving core meaning or function).

Techniques: Approaches rely on heuristics, statistical thresholds, linguistic analysis, and redaction. In text, deléció may involve deleting filler words or nonessential clauses; in media, it may involve removing metadata or sensitive segments.

Applications: It is discussed in privacy-preserving data sharing, digital archiving, content moderation, and user-interface design for information dashboards.

Limitations and criticism: Critics point to potential loss of information, contextual biases, and reproducibility issues. Ethical considerations include consent, fairness, and the risk of erasing historical detail.
