Knowledge management rests on information systems such as Decision Support Systems (DSS) and Expert Systems (ES). this paper focuses on ES, described as formal systems based on Well Formed Formulas (WFF), axioms and inference rules. the basic axioms gathers explicit codified knowledge like regulations, codes, processes, copyrights and patents into a knowledge database, the first component of the ES. the valid well formed inference rules are evaluated by forward chaining (if...then patterns) by the inference engine, the second ES component. those two united components forms a deductive apparatus fueled by the organization intellectual capital.

A multiple-agent logic, which associates subsets of agents to logical formulas, has been recently proposed. the paper presents a graphical counterpart of this logic, based on a multiple agent version of possibilistic conditioning, and applies it to preference modeling. First, preferences of agents are supposed to be all or nothing. We discuss how one can move from the network to the logic representation and viceversa. the new representation enables us to focus on networks associated to subsets of agents, and to identify inconsistent agents, or conflicting subsets of agents. the question of optimization and dominance queries is discussed. Finally, the paper outlines an extension where gradual preferences are handled.

Mutation testing assesses test suite efficacy by inserting small faults into programs and measuring the ability of the test suite to detect them. It is widely considered the strongest test criterion in terms of finding the most faults and it subsumes a number of other coverage criteria. Traditional mutation analysis is computationally prohibitive which hinders its adoption as an industry standard. In order to alleviate the computational issues, we present a diff-based probabilistic approach to mutation analysis that drastically reduces the number of mutants by omitting lines of code without statement coverage and lines that are determined to be uninteresting - we dub these arid lines . Furthermore, by reducing the number of mutants and carefully selecting only the most interesting ones we make it easier for humans to understand and evaluate the result of mutation analysis. We propose a heuristic for judging whether a node is arid or not, conditioned on the programming language. We focus on a code-review based approach and consider the effects of surfacing mutation results on developer attention. the described system is used by 6,000 engineers in Google on all code changes they author or review, affecting in total more than 13,000 code authors as part of the mandatory code review process. the system processes about 30% of all diffs across Google that have statement coverage calculated. About 15% of coverage statement calculations fail across Google.

WalkSAT is a local search algorithm conceived for solving SAT problems, which is also used for sampling possible worlds from a logical formula. this algorithm is used by Markov logic Networks to perform slice sampling and give probabilities from a knowledge base defined with soft and hard constraints. In this paper, we will show that local search strategies, such as WalkSAT, may perform as poorly as a pure random walk on a category of problems that are quite common in industrial fields. We will also give some insights into the reasons that make random search algorithms intractable for these problems.

A dynamic framework, based on the Dynamic logic of Propositional Assignments (DL-PA), has recently been proposed for Dung's abstract argument system. this framework allows the addition and the removal of attacks, and the modification of the acceptance status of arguments. We here extend this framework in order to capture the addition and the removal of arguments. We then apply the framework on an access control case, where an agent engages in an argued dialogue to access some information controlled by another agent.

Credit risk is considered as one of the important issues for financial institutions. It provokes great losses for banks. To this objective, numerous methods for credit risk evaluation have been proposed. Many evaluation methods are black box models that cannot adequately reveal information hidden in the data. However, several works have focused on building transparent rules-based models. For credit risk assessment, generated rules must be not only highly accurate, but also highly interpretable. In this paper, we aim to build both, an accurate and transparent credit risk evaluation model which proposes a set of classification rules. In fact, we consider the credit risk evaluation as an optimization problem which uses a genetic programming (GP) algorithm, where the goal is to maximize the accuracy of generated rules. We evaluate our proposed approach on the base of German and Australian credit datasets. We compared our finding with some existing works;the result shows that the proposed GP outperforms the other models.

Article addresses the issue of the EU funds approved after Romania joined the European Union, highlighting with a technical analysis from the first programming period 2007-2013, but also for the period 2014-2020, their direct applicability to their degree of absorption (Structural and Cohesion Funds) in Romania. the Structural Funds are implemented through five Sectoral Operational Programs (SOP, respectively FUR 4.5 bilion -for transport, EUR 3.4 bilion - for human resources development, FUR 2.5 bilion - to increase economic competitiveness, EUR 208 million - for Development of administrative capacity, EUR 4.5 billion - for the environment), a regional development program (ROP, respectively EUR 3.7 billion) and a technical assistance program (EUR 170 million). After analyzing the degree of absorption of the funds, one can observe a paradox of the public litigation, on the one hand, the sum of the current receipts and the measures taken in the past, and on the other hand,it confirms how slow the European funds are accessed.
