Stage: stereotypical trust assessment through graph extraction
(Wiley, 2016-02)
Bootstrapping trust assessment where there is little or no evidence regarding a subject is a significant challenge for existing trust and reputation systems. When direct or indirect evidence is absent, existing approaches ...
Inference management, trust and obfuscation principles for quality of information in emerging pervasive environments
(Elsevier, 2014-04)
The emergence of large scale, distributed, sensor-enabled, machine-to-machine pervasive applications necessitates engaging with providers of information on demand to collect the information, of varying quality levels, to ...
A hybrid reasoning mechanism for effective sensor selection for tasks
(Elsevier, 2013-02)
In this paper, we present Ontological Logic Programming (OLP), a novel approach that combines logic programming with ontological reasoning. OLP enables the use of ontological terms (i.e., individuals, classes and properties) ...
SHACL constraints with inference rules
(Springer Nature, 2019)
The Shapes Constraint Language (SHACL) has been recently introduced as a W3C recommendation to define constraints that can be validated against RDF graphs. Interactions of SHACL with other Semantic Web technologies, such ...
Goal directed policy conflict detection and prioritisation: an empirical evaluation
(Springer Science+Business Media, 2014)
We address the problem of developing effective automated reasoning support for the detection and resolution of conflicts between plans and policies (or norms). How automated reasoning mechanisms can effectively support ...
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 ...
TIDY: A trust-based approach to information fusion through diversity
(IEEE, 2013)
Trust and reputation are significant components in open dynamic systems for making informed and reliable decisions. State-of-the-art information fusion models that exploit these mechanisms generally rely on reports from ...
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 ...
