Information Retrieval and Dempster-Shafer’s Theory of Evidence
1998This paper describes the use of the Dempster-Shafer theory of evidence to construct an information retrieval model that aims to capture four essential features of information: structure, significance, uncertainty and partiality. We show that Dempster-Shafer’s initial framework allows the representation of the structure and the significance of ...

Connections between rough set theory and Dempster-Shafer theory of evidence
International Journal of General Systems, 2002In rough set theory there exists a pair of approximation operators, the upper and lower approximations, whereas in Dempster-Shafer theory of evidence there exists a dual pair of uncertainty measures, the plausibility and belief functions. It seems that there is some kind of natural connection between the two theories.

Rate-Unknown Image Steganalysis Based on Dempster-Shafer Evidence Theory
2012 Fourth International Conference on Multimedia Information Networking and Security, 2012The existing detection algorithms are difficult to obtain high detection accuracy when applied to the condition, in which the embedding rate of the stego-images is unknown. Therefore, it is very difficult to adopt the existing image steganalysis techniques in the design of a practical covert communication detection system.

Expert finding by the Dempster‐Shafer theory for evidence combination
Expert Systems, 2017AbstractThe expertise of human experts can be formally extracted from their written documents, research projects, and everyday activities. The process whereby experts are recognized according to their activities is called expert finding. In this paper, we propose an approach to identify the experts in a given field according to the content of 3 easily ...

Models Based on the Dempster-Shafer Theory of Evidence
1991Like Bayesian approaches, the Dempster-Shafer theory of evidence aims to model and quantify uncertainty by degrees of belief. But in contrast to Bayesian approaches it permits assignment of degrees of belief to sets of hypotheses rather than to hypotheses in isolation.

Situation Theory and Dempster-Shafer’s Theory of Evidence for Information Retrieval
1994We propose a model of information retrieval systems that is based on a Theory of Information and a Theory of Uncertainty, respectively Situation Theory and Dempster-Shafer’s Theory of Evidence. These were selected because they allow us to tackle two of the main problems that confront any attempt to model an information retrieval system: the ...

Research on Threat Assessment Based on Dempster–Shafer Evidence Theory
2012Based on D−S evidence theory, a new method of multi-target threat evaluating and sequencing is presented. Firstly, the concerned problems are defined and formalized using fuzzy sets and fuzzy number. Secondly, the BPA is obtained by using the similarity measure between generalized fuzzy numbers. Lastly, D−S evidence theory is applied to combine the BPA

Interval Comparison Based on Dempster-Shafer Theory of Evidence
2004The problem of crisp and fuzzy interval (number) comparison is of perennial interest, because of its direct relevance in practical modeling and optimization of real-world processes under uncertainty. There are many approaches to this problem presented in literature, but in all cases the authors propose the methods which give the result of interval ...
