Organization based access control
TLDR
We propose a new security policy model that provides solutions to specify contextual security policies that are not restricted to static permissions, prohibitions, obligations and recommendations. Expand

Inconsistency Management and Prioritized Syntax-Based Entailment
TLDR
We study the behavior of non-monotonic inferences induced by various methods for priority-based handling of classical formulas. Expand

Naive Bayes vs decision trees in intrusion detection systems
TLDR
We show that even if having a simple structure, naive Bayes provide very competitive results in intrusion detection. Expand

Fusion: General concepts and characteristics
TLDR
This paper aims at presenting the different aspects of information fusion in different domains, such as databases, regulations, preferences, sensor fusion, etc., at a quite general level. Expand

Some Syntactic Approaches to the Handling of Inconsistent Knowledge Bases: A Comparative Study Part 1: The Flat Case
TLDR
This paper presents and discusses several methods for reasoning from inconsistent knowledge bases under different inconsistency-tolerant consequence relations, namely the so-called argumentative, free, universal, existential, cardinality-based, and paraconsistent consequence relations. Expand

Nonmonotonic Reasoning, Conditional Objects and Possibility Theory
TLDR
We show that conditional objects, a purely qualitative counterpart to conditional probabilities, offer a very simple semantics, based on a 3-valued calculus, for the preferential entailment, while in the purely ordinal setting of possibility theory both the preferential and the rational closure entailments can be represented.

TLDR
The bipolar view in preference modeling distinguishes between negative and positive preferences. Expand

A Practical Approach to Revising Prioritized Knowledge Bases
TLDR
This paper investigates simple syntactic methods for revising prioritized belief bases, that are semantically meaningful in the frameworks of possibility theory and of Spohn's ordinal conditional functions. Expand
