A Generalized Binary Probabilistic Independence Model.

Wong, S. K. M.; Yao, Y. Y.

Journal of the American Society for Information Science, v41 n5 p324-29 Jul 1990

Describes a theoretical model based on binary vectors that was developed to improve relevance in information retrieval systems. Earlier probabilistic models are examined, quadratic and linear discriminant functions are discussed, relationships between queries and documents are considered, and further research is suggested.
