   Probabilistic $\text{IR}$ models aim to estimate the probability that a document is relevant to a query, conditioned on the observed term distributions. The Binary Independence Model ($\text{BIM}$) assumes term occurrences are statistically independent, a premise often violated in natural language but mathematically convenient. More advanced models, such as the Probabilistic Relevance Model ($\text{PRM}$), use [feedback loops](/entries/feed…
