personalizacj

Personalizacja is the process of tailoring products, services, or content to the individual preferences, needs, or context of a user. It relies on data about the user and on rules or statistical models that determine what to show or how to interact. It is used in marketing, digital platforms, software, media, and education. In Polish, the standard term is personalizacja.

Data sources include explicit inputs (user-provided preferences, settings, demographics), and implicit signals (past behavior, clicks, dwell time), as well as contextual factors (location, device, time). Methods include segmentation, rule-based targeting, and machine learning approaches such as collaborative filtering, content-based recommendations, and hybrid models. Personalization may be implemented dynamically, updating as new data arrives.

Applications include product recommendations in e-commerce, personalized emails, adaptive interfaces, personalized search results, targeted advertising, and educational platforms that adjust content to learner needs. Benefits include increased relevance, engagement, conversion, and user satisfaction, as well as efficiency for organizations. Risks include privacy and data protection concerns, potential bias or discrimination, creation of filter bubbles, overfitting to historical data, and a loss of serendipity.

Regulation and governance emphasize privacy, transparency, consent, data minimization, and user control. Compliance frameworks such as the European Union's GDPR and other regional laws influence how personal data may be collected and used. Technical challenges include data quality, model bias, explainability, and monitoring; ethical considerations address autonomy and fairness in automated decisions.
