Combination of Evidence in Dempster-Shafer Theory [PDF]

open access: yes, 2002
Dempster-Shafer theory offers an alternative to traditional probabilistic theory for the mathematical representation of uncertainty. The significant innovation of this framework is that it allows for the allocation of a probability mass to sets or intervals.

Stock portfolio selection using Dempster–Shafer evidence theory

open access: yesJournal of King Saud University: Computer and Information Sciences, 2018
Markowitz’s return–risk model for stock portfolio selection is based on the historical return data of assets. In addition to the effect of historical return, there are many other critical factors which directly or indirectly influence the stock market ...

Using the Dempster-Shafer Theory of Evidence to Resolve ABox Inconsistencies [PDF]

open access: yes, 2008
Automated ontology population using information extraction algorithms can produce inconsistent knowledge bases. Confidence values assigned by the extraction algorithms may serve as evidence in helping to repair inconsistencies. The Dempster-Shafer theory of evidence is a formalism, which allows appropriate interpretation of extractors' confidence ...

Modeling Partially Reliable Information Sources: A General Approach Based on Dempster-Shafer Theory [PDF]

open access: yes, 2005
Combining testimonial reports from independent and partially reliable information sources is an important problem of uncertain reasoning. Within the framework of Dempster-Shafer theory, we propose a general model of partially reliable sources which ...

Human Cognitive Models for Heritage Site Monitoring

open access: yesDigital Presentation and Preservation of Cultural and Scientific Heritage, 2021
Integrating evidence from a single sensor over time is becoming more common due to the Internet of Things (IoT). It can play a critical role in Heritage site monitoring, as networks of sensors are required to catalog and analyze data over extended ...

Measuring Uncertainty in the Negation Evidence for Multi-Source Information Fusion

open access: yesEntropy, 2022
Dempster–Shafer evidence theory is widely used in modeling and reasoning uncertain information in real applications. Recently, a new perspective of modeling uncertain information with the negation of evidence was proposed and has attracted a lot of ...

Indistinguishability relations in Dempster–Shafer theory of evidence

open access: yesInternational Journal of Approximate Reasoning, 2004
Each theory or model implicitly defines its inherent notion of equality for the objects in question. In turn, this equality, and its counterpart, the mathematical concept of equivalence, provides the basis on which to establish classification mechanisms for the domain at hand.
