Existing security models require that information of a given security level be prevented from “leaking” into lower-security information. High-security applications must be dem...
This paper presents a new discriminative model for information retrieval (IR), referred to as linear discriminant model (LDM), which provides a flexible framework to incorporate a...
The language modeling approach to retrieval has been shown to perform well empirically. One advantage of this new approach is its statistical foundations. However, feedback, as on...
Abstract. We propose a probabalistic model of single source multimodal generation and show how algorithms for maximizing mutual information can find the correspondences between com...
In this paper I propose a model for situated information processing based on a set of layers, each related to a different processing phase and to a different context type. The mod...
