Strategies for truth discovery under resource constraints
(ACM, 2015)
We present a decision-theoretic approach for sampling information sources in resource-constrained environments, where there is uncertainty regarding source trustworthiness. We exploit diversity among sources to stratify ...
TRIBE: Trust revision for information based on evidence
(IEEE, 2013)
In recent years, the number of information sources available to support decision-making has increased dramatically. However, more information sources do not always mean higher precision in the fused information. This is ...
Reasoning with uncertain information and trust
(SPIE, 2013)
A limitation of standard Description Logics is its inability to reason with uncertain and vague knowledge. Although probabilistic and fuzzy extensions of DLs exist, which provide an explicit representation of uncertainty, ...
How to trust a few among many
(Springer International Publishing, 2017)
The presence of numerous and disparate information sources available to support decision-making calls for efficient methods of harnessing their potential. Information sources may be unreliable, and misleading reports can ...
Semantic reasoning with uncertain information from unreliable sources
(Springer International Publishing, 2016)
Intelligent software agents may significantly benefit from semantic reasoning. However, existing semantic reasoners are based on Description Logics, which cannot handle vague, incomplete, and unreliable knowledge. In this ...
Reasoning about uncertain information and conflict resolution through trust revision
(International Foundation for Autonomous Agents and Multiagent Systems, 2013)
In information driven MAS, information consumers collect information about their environment from various sources such as sensors. However, there is no guarantee that a source will provide the requested information truthfully ...
SOBE: Source behavior estimation for subjective opinions In multiagent systems
(International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2016)
In cooperative or hostile environments, agents communicate their subjective opinions about various phenomenon. However, sources
of these opinions may not always be competent and honest but more likely erroneous or even ...
