Récence

Récence is a term used in various fields, primarily in information retrieval and data management, to denote the freshness or timeliness of information. In the context of search engines, recence refers to how recently a document or webpage was created or updated. Search algorithms often consider recency as a factor when ranking results, with more current information sometimes being preferred, especially for queries where timeliness is important, such as news or product releases.

The concept of recence is also relevant in data analysis and time series forecasting. When analyzing data collected over time, the most recent data points may hold more predictive power or relevance for understanding current trends. Therefore, weighting or prioritizing recent data can be a crucial aspect of building accurate models.

In library science and archival practices, recence can influence collection development and cataloging. Newer acquisitions or materials might be highlighted or accessed differently. The definition and importance of recence can vary depending on the specific application and the nature of the information being managed. Generally, it addresses the question of how "new" something is and why that aspect matters for its use or interpretation.
