✦ Synopsis

The main objective of this article is to develop a theoretical model for information retrieval. By utilizing more complete statistical information, a generalized binary probabilistic independence model is proposed. Earlier probabilistic independence models are shown to be special cases of the new model. A quadratic discriminant function is obtained, which can be reduced to the linear discriminant functions of the conventional probabilistic models.
