Designing Possibilistic Information Fusion—The Importance of Associativity, Consistency, and Redundancy

Possibilistic Information Flow Control

Distributed systems make increasing use of encrypted channels to enable confidential communication. While non-interference provides suitable means to investigate the flow of information within distributed systems, it has proved to be rather difficult to capture the notion of encrypted channels in such a framework. In this paper, we extend the framework MAKS for possibilistic information flow in...

an investigation into iranian teachers consistency and bias in evaluation of students writings

while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...

Associativity and Non-Associativity of Some Hypergraph Products

Several variants of hypergraph products have been introduced as generalizations of the strong and direct products of graphs. Here we show that only some of them are associative. In addition to the Cartesian product, these are the minimal rank preserving direct product, and the normal product. Counter-examples are given for the strong product as well as the non-rank-preserving and the maximal ra...

Information Retrieval by Possibilistic Reasoning

Causality Consistency Problem for Two Different Possibilistic Causal Models

Conditional Causal Probability (CCPR) and Conditional Causal Possibility (CCPO) have been proposed to express exact uncertainties of causalities, and some reasoning methods based on them have been studied to calculate probabilities or possibilities of unknown events under the condition that some events are known. CCPR/CCPO is a conditional probability/possibility of a causation event conditione...
