摘要
The probabilistic approach to document and text retrieval adopts standard probability theory, applied via the Probability Ranking Principle, as a sufficient foundation for retrieval theory. Proposals for how this approach might best be carried out include the use of statistical independence or linked dependence assumptions, regression analysis, and the application of the Maximum Entropy Principle.
